1 – Introduction to the DA-98HR
The TASCAM DA-98HR is a digital audio multi-
track recorder designed for use in a variety of appli-
cations, including video post-production and audio
multitrack work.
1.2
Features
Key features of the DA-98HR include:
• TASCAM-exclusive high-performance/high wear
resistive rotary 4-head mechanism with TASCAM
original track layout (DTRS standard)
It records up to 8 tracks of full-quality digital audio
on standard Hi8 video cassettes using a specially-
designed transport and head mechanism. Using this
medium, up to 108 minutes of continuous recording
is possible on a single NTSC “120” tape.
• Use of standard, low-cost media with long record-
ing and playback times
• 16-bit or 24-bit recording
Recording is carried out at either 24 bits or 16 bits of
resolution, and digital data may be input at 16, 20 or
24 bits of resolution.
• “Traditional” and high-speed sampling rates for
ultimate sonic performance
• Different sampling frequencies can be recorded
simultaneously on different tracks on the same
tape, providing ultimate flexibility
As well as the “traditional” industry-standard
44.1 kHz and 48 kHz sampling frequencies, the DA-
98HR can also record and playback at double and
four times these sampling frequencies: 88.2 kHz and
176.4 kHz, and 96 kHz and 192 kHz.
• Fast, frame-accurate tape location and positioning;
end-to-end winding for a “120” tape is around 80
seconds
The DA-98HR builds on the foundations laid by the
TASCAM DA-78HR, DA98, DA-88 and DA-38 digi-
tal multitrack recorders, and retains compatibility
with them. Tapes recorded on one of the DTRS series
can be replayed and overdubbed on any other
• Direct digital synchronization of up to 16 DTRS
recorders (128 tracks) without the use of any exter-
nal synchronizer or controller
• Direct digital dubbing between DTRS units

• Input patchbay provides an internal digital patch-
bay, allowing input-to-track assignment without the
use of external equipment
ject to the word length and sampling frequency capa-
bilities of both machines.
• Output patchbay allows the routing of tracks to out-
puts without the need for external equipment
NOTE
Recording is an art as well as a science. A successful
recording is often judged primarily on the quality of sound
as art, and we obviously cannot guarantee that. A com-
pany that makes paint and brushes for artists cannot say
that the paintings made with their products will be critically
well-received. TASCAM can make no guarantee that the
DA-98HR by itself will assure the quality of the recordings
you make. Your skill as a technician and your abilities as an
artist will be significant factors in the results you achieve.
• 15-segment peak meters with user-selectable fall
ballistics and variable hold time (including contin-
uous peak hold)
• Integral digital sine oscillator, providing signals at
440Hz for tuning and 1kHz for lineup purposes
• Digital input and output in TDIF-1 format on a sin-
gle convenient compact D-sub connector
• Eight channels of AES/EBU I/O on a single conve-
nient compact D-sub connector

Notes and precautions
7, “Advanced operations”: Operations that you will
not necessarily perform every day, but are necessary
for the successful operation of the DA-98HR.
As with any precision piece of electronic equipment,
common-sense precautions apply with the DA-
98HR.
However, there are a few extra notes and precautions
which apply to using the DA-98HR, and we suggest
8 TASCAM DA-98HR
1 – Introduction to the DA-98HR–Notes and precautions
that you make a note of these, to prolong the useful
life of the DA-98HR.
Relative humidity should be between 30% and 80%
non-condensing
There should be no strong magnetic fields (speakers,
etc.) near the DA-98HR.
1.4.1 Clock source in a digital studio
The DA-98HR can be used in a variety of situations,
and with a variety of equipment, either digital or ana-
log.
Avoid spraying polish, insecticides, etc. near the DA-
98HR.
NOTE
If you are working with more than one digital audio
unit in your setup, you should note that all units must
be driven by the same central clock source (“word
clock” or “word sync”).
If you need to clean the DA-98HR, use a soft cloth, moist-
ened if necessary with a little detergent and water. Do not
use abrasive cleaners or solvents such as alcohol or
thinner.
If different word clock sources are used throughout
the setup, it is actually possible to damage speakers,
etc. because of mismatches.
Avoid subjecting the DA-98HR to jolts, sudden
shocks, etc.
NOTE
The DA-98HR can be designated as the word clock
master for your studio, or can be slaved to external
word clocks, using a convenient front-panel switch
and standard BNC connectors.
If you have to return the unit for service or repair, use the
original packing materials if possible. If the unit is to be
transported to a recording location, etc., use a suitable
transport case with sufficient shock protection.
Even though AES/EBU stereo digital audio signals
are self-clocking, any AES/EBU format signals fed
to or from the DA-98HR must be synchronized at
word level with the DA-98HR.
TASCAM does not accept responsibility for damage
resulting from neglect or accident.
1.4.4 Installing the DA-98HR
1.4.2 Confidence replay
The DA-98HR may be installed in a standard 19”
rack, occupying 4U of space. Since the DA-98HR is
quite heavy (around 11kg – 24lb), your rack should
be strong and stable to take the weight of the DA-
98HR.
Because the DA-98HR can accept digital data at dif-
ferent sampling frequencies, and the word length is
may be either 16 or 24 bits, monitoring the input
source during recording will not necessarily provide
a completely accurate representation of what is
recorded on tape.
The DA-98HR should be mounted with the front
panel vertical.
The DA-98HR provides a dither setting (7.12.1,
total harmonic distortion figures for 16-bit recording.
Since the dither is applied prior to recording, again,
monitoring the input source will not allow you to
hear the effect of the dithering process.
Accordingly, the DA-98HR provides a confidence
mode, allowing you to monitor off-tape as recording
progresses. Since this monitoring is not synchronized
exactly with the source inputs, gapless punch-in and
punch-out is not possible in confidence mode. For
full details of confidence monitoring, together with
other monitoring modes available on the DA-98HR,
1.4.5 Electrical considerations
Make sure that your local power supply matches the
voltage requirements marked on the rear panel of the
DA-98HR.
1.4.3 Environmental conditions
The DA-98HR can be operated in most environ-
ments, but we suggest that you keep the environmen-
tal conditions within the following limits:
If you are in any doubt concerning the local power
supply, consult an electrician.
Ambient temperature between 5° and 35° C (41°
and 95° F).
TASCAM DA-98HR 9
1 – Introduction to the DA-98HR–Recommended tapes
Avoid extreme voltage fluctuations. If necessary, use
an input voltage regulator to smooth the power sup-
plied to the DA-98HR.
1.5
Recommended tapes
The DA-98HR is designed for use with Hi8 video
cassettes. You cannot use any other kind of tape with
the DA-98HR.
Do not open the unit to clean inside, or to perform
any internal adjustments. You should not attempt any
cleaning or other maintenance procedures which are
not described in this manual.
There are two basic types of Hi8 tape: MP and ME.
Each has its own particular characteristics and mer-
its:
You may need to clean the heads occasionally. The
procedure for doing this, and for checking tape error
• MP tapes are manufactured using a daubed mag-
netic particle deposit process and exhibit a level of
performance which is more than acceptable. They
have a durability which allows them to be used as
work tapes in studio and post-production
environments.
1.4.6 Condensation
If you use the DA-98HR in a warm place after mov-
ing it from a cold place (for instance, recording on
location), or if there has been a sudden change in
temperature, condensation may occur within the tape
mechanism, with a risk of possible damage to the
unit.
• ME tapes have their magnetic layer produced
through a metal evaporation process. Generally
speaking, though these tapes have a high perfor-
mance level, they are not as robust as MP tapes (see
above) and should be used for live recording and
archival purposes, rather than as work tapes.
If condensation does occur, you will not be able to
operate the DA-98HR controls, and you will see the
following message on the display:
TASCAM does not endorse any specific tape or tape
manufacturer. TASCAM has licensed the use of the
WARNING !
DTRS logo (
) to tape manufacturers, provided
Condensation on drum
their tape meets the specifications required by DTRS
tape recorders. However, the use of the DTRS logo
on the tape packaging does not imply any endorse-
ment of the tape by TASCAM. It is possible that the
characteristics and sensitivities of tapes may be
changed by the manufacturers without notice. The
brands and model numbers of tapes listed below may
not always meet the specifications required by DTRS
systems for optimum performance. TASCAM
assumes no responsibility for problems resulting
from changes made by a manufacturer to the materi-
als or specifications of its tape products.
If you see the above message, press the ESCAPE key
to remove the message, leave the DA-98HR switched
on for one or two hours, then switch it off and on
again before starting recording.
If you are going to use the DA-98HR in a location
where you think condensation is likely to occur,
move the DA-98HR into the warmer location about
one or two hours before recording is due to start, and
leave it switched on. Turn the DA-98HR off and then
on again before starting recording.
The electrical characteristics of DTRS recorders are
adjusted and set using Sony Hi8 tape parameters (MP
and ME) prior to shipment.

The following brands and models of tape can be used
with the DA-98HR. As mentioned above, this list
does not constitute any endorsement by TASCAM of
these products, nor is it a guarantee that tapes bearing
this brand and model name will continue to give opti-
mum performance.
Depending on whether the tape has been purchased
for use with an NTSC (P6/E6) or a PAL/SECAM
(P5/E5) television system, the same length of tape (as
far as video length is concerned) will provide differ-
ent times for audio work, as shown below, due to dif-

The electronics of DTRS recorders are designed to
operate within specific parameters. The use of a tape
with sensitivity higher or lower than that of tapes for
which the DTRS recorder was originally designed
may cause an error in functionality or prevent the
user from getting optimum performance from the
tape. Always use the shortest possible tape for a
given project. Do not attempt to use 150-minute or
longer tapes in DTRS machines, as the machine will
detect the thickness of tape and automatically eject
any tape thinner than recommended.
Never attempt to use a tape with the DA-98HR that
has previously been used in video equipment.
NOTE
You cannot cut and splice DTRS 8mm tapes for editing pur-
poses. Using a spliced tape in the DA-98HR will invariably
result in serious damage to the heads, requiring replace-
ment. All editing must be done digitally.

This section explains how to connect other equip-
ment to the DA-98HR in a variety of situations. It is
not intended as a complete reference to the use of the
DA-98HR. See the appropriate sections for full
details of how these connectors are used.
Before starting to make the cable, we suggest you
contact your TASCAM dealer for full details of cable
specifications, etc.
The pinouts for both the ANALOG OUTPUT and
INPUT connectors are given in the manual for these
boards, as are detailed specifications and
NOTE
S
When making connections between the DA-98HR and
other equipment, whether audio or control, both the DA-
98HR and the other equipment must be turned off, other-
wise damage may be caused to the DA-98HR and/or the
other equipment.
All audio inputs are balanced and are rated at a nom-
inal +4dBu level.
The impedance of the inputs is 20kΩ and that of the
outputs is 10Ω.
Only use TASCAM-supplied and TASCAM-approved
cables when making connections to the DA-98HR. Though
the cables and connectors may resemble computer cables,
they serve different purposes, and meet a different set of
specifications. The use of cables other than TASCAM
cables will at best cause the equipment to work erratically,
and at worst cause damage to the equipment.
3.1.2 Digital audio connections (using
TDIF-1)

To carry signals between a DA-98HR and another
DTRS unit or a suitably-equipped digital mixing
console, use a PW-88D cable (1 meter long) or a PW-
88DL cable (5 meters long).
If the use of cables other than TASCAM cables causes or
results in damage, the warranty is voided.
NOTE
3.1
Audio connection
Although the TDIF-1 and AES connectors use the same
type of 25-pin D-sub connector, it is not possible to connect
a TDIF-1 -equipped unit directly to an AES/EBU-equipped
unit. An interface such as the IF-AE8HR must be used to
convert the signals.
Other audio equipment can be connected to the DA-
98HR either using optional analog or digital inter-
faces.
3.1.1 Analog audio connections
(optional IF-AN98HR)
3.1.3 Digital audio connections (using
AES/EBU)
All analog audio connections to the DA-98HR are
made through 25-pin D-sub connectors to the
optional analog slot 2-board set, IF-AN98HR.
The AES/EBU connections (strictly speaking, this
format is AES3-1992 Amendment 3-1999) allow
direct connections between the DA-98HR and suit-
ably-equipped devices.
This allows convenient and tidy cabling between the
DA-98HR and other units such as the TASCAM M-
1600 series of mixing consoles.
NOTE
If four dual-frequency (i.e. 88.2 kHz or 96 kHz) tracks have
been selected as the available tracks, see also 7.10.3,
It is not recommended that you make up your own
cables—consult your TASCAM dealer for availabil-
ity of suitable ready-made cables. However, we rec-
ognize that every situation has its own unique
features, and there are occasions when a special cable
must be made.
The AES x2 IOmenu item (menu group A),
allows the choice of either dual lineor

If the menu value is an individual field in a time
value, as described, all the fields are reset to zero. If
the whole time value is flashing, this action also
resets the whole of the time value. If there is more
than one independent field in a menu screen, use the
cursor to point to the value that you want to reset to
zero and then perform this action.
The screen relights, and shows the top menu.

5 – Monitoring modes
the source input rather than the recorded signal, even
in play mode.
NOTE
We strongly advise you to read this section—the effective
use of multitrack monitoring is one of the keys to an effi-
cient recording session.
The following table shows what will be monitored
from a track. This depends on the AUTO MON and
the REC FUNCTION switch settings, and on the
transport mode currently engaged.
Like all multitrack recorders, the DA-98HR has a
number of different monitoring modes, depending on
the current monitor status, transport status and
whether the track is armed or not.
In addition to the “standard” modes common to most
multitrack recorders, the DA-98HR includes two spe-
cial monitoring features: the CONFIDENCE MODE
switches . These are described in this section.

only possible when the tape is moving (in recording or play-
back modes).
this mode (AUTO MON off and REC FUNCTION on) and
when confidence mode is active, the monitoring is selectable
between source and tape.
5.1.1 ALL INPUT and INPUT MONITOR
When these are active, the signal from the DA-
98HR’s outputs will always be the input source sig-
nal received at the input for the appropriate track or
tracks.
The AUTO MON function therefore allows you to
switch automatically between monitoring modes as
the tape transport function changes.
When the ALL INPUT key is pressed, its indicator
and the INPUT MONITOR indicators of all tracks
light. Monitoring for all tracks is then of the input
sources.
NOTE
The ALL INPUT key overrides the monitoring mode from
the table above (when this mode is active, monitoring for all
tracks will always be source monitoring, regardless of the
status of AUTO MON).
When the ALL INPUT key is pressed again to turn off
this mode, the status of the INPUT MONITOR indica-
tors will revert to the status before the ALL INPUT
key was turned on.
5.1.3 Shuttle monitoring
In addition to these modes, there is one further menu
item, that affects monitoring, but only in one special
case – shuttle mode. Usually, when shuttling the tape,
you will want to monitor the tape. However, if a track
is armed, you may want to listen to the source input
signal, rather than the recorded signals.
The INPUT MONITOR switches are disabled until the
ALL INPUT key is turned off (the ALL INPUT indica-
tor goes out).
The INPUT MONITOR switches allow you to perform
the same function on a track-by-track basis, allowing
you to check the input source, and are available from
a number of modes as described in the table below.
NOTE
ALL INPUT overrides any shuttle monitoring selections
described below. Any shuttle monitoring while ALL
INPUT is on will always be source monitoring.
5.1.2 AUTO MON
When replaying a track, you will usually want to
monitor the program material recorded on the tape.
However, there are times when you want to monitor

between onand off.
The shuttle monitoring setting key has no effect
when AUTO MON is off. While shuttling, you can use
tracks’ INPUT MONITOR switches (regardless of
arming status) to change between source and tape
monitoring.
Note that a track may be routed to more than
one channel. In the screen above, the routing is
“normalled”, except that tracks 2 and 3 are
routed to output channels 3 and 2 respectively,
and track 8 is paralleled to channels 7 and 8.
When the AUTO MON and shuttle monitoring are
both on (the indicators will light), the output from all
armed tracks will be the source input. This cannot be
changed.
When the outputs are not “normalled”, i.e.
there is no longer a one-to-one correspondence
between the tracks and the output channels,
the OUTPUT PATCH indicator under the tape
counter lights.
NOTE
You can always (regardless of any other status except ALL
INPUT) use the INPUT MONITOR switch of unarmed
tracks to switch between source and tape monitoring.
NOTE
The number of tracks available, and their possible assign-
ments, vary according to the number of available tracks
If AUTO MON is on, but the shuttle monitoring mode
is turned off, all armed tracks will monitor the
recorded signals in shuttle mode. This cannot be
changed.

You can also disable shuttle monitoring with the Shuttle
When recording in a studio, it is usual to monitor the
input signals, rather than the tape. This allows accu-
rate synchronization between studio events and the
actions of the control room staff. If a “glitch” is later
discovered in the recording, or it is discovered that a
signal has been wrongly routed, resulting in an
unwanted recording being produced, it is a relatively
simple matter to re-record the take.
Shuttle monitoring is attenuated by 12 dB compared with
other monitoring modes. This helps to avoid damage to
tweeters, etc. when shuttling fast.
5.2
Patching the outputs
The tracks do not have to be assigned to the outputs
on a one-to-one basis. This may be useful in situa-
tions where a digital audio patchbay is not available.
In a live recording situation, this luxury is not possi-
ble. One can hardly ask an orchestra giving a concert
to repeat a movement of a symphony for re-recording
purposes!
NOTE
Note that this routing function only allows rerouting
between tracks of the same sampling frequency. It is not
possible, for instance, to assign a double-frequency track to
an output which would normally be used by a base-fre-
quency track.
For this reason, the DA-98HR includes a confidence
mode which permits off-tape monitoring on a track-
by-track basis while recording is in progress.
Confidence mode provides monitoring off-tape while
recording for all tracks, except those tracks whose
INPUT MONITOR switch is active. The monitoring of
these tracks will be the input source, not tape.
The outputs are made in parallel on both the AES/
EBU and the TDIF-1 outputs (though only one may
be selected at a time). If an optional slot board has
been installed, the outputs will also be output from
there.
The actual mechanics of how this is accomplished
internally are quite complex, but the result is that off-
28 TASCAM DA-98HR
5 – Monitoring modes–Mixdown patchbay
tape signals are delayed by about 240 milliseconds
NOTE
relative to the input signal. This means that it is not
recommended that you perform punch-ins, etc. in the
confidence mode.
Using confidence mode, it is possible to monitor some
tracks off-tape during recording while monitoring the input
source of others. However, as explained above, the way in
which the confidence mode is implemented means that the
off-tape signals are delayed by 240 milliseconds relative to
the input source signals. Hence, the off-tape and source
signals will be out of sync. We therefore recommend that
this function is only used when dubbing.
In the confidence mode, overdubbing will be out of
sync with previously recorded tracks, as well as with
the input source.
We suggest you use confidence mode only when lay-
ing down long takes of basic tracks which will not
need punching for correction (e.g. laying down tracks
from a video worktape, or classical live recordings).
You may also choose to use confidence mode when
you are dubbing from another audio multitrack tape
to the DA-98HR, to ensure the quality of the transfer.
The indicator will flash.
4 Press the CONFIDENCE MODE key again
within five seconds of pressing it for the first
time. The indicator will light steadily.
Another use for the confidence mode is when you are
want to check the effects of dither on the re-quan-
tized recording as the tracks are being laid down.
If you do not press the CONFIDENCE MODE
key twice within five seconds, the indicator will
stop flashing. This is to stop you from entering
the confidence mode by accident.
5 To leave confidence mode, press the CONFI-
5.3.1 Arming tracks in pairs
DENCE MODE key once.
Note that in confidence mode, tracks at the base sam-
pling frequency are always armed and unarmed in
pairs (1+2, 3+4, 5+6, 7+8). Dual-frequency and
quad-frequency tracks may be armed and unarmed
individually.
5.4
Mixdown patchbay
In addition to the routing, it is also possible to mix
down eight signals (as a mixture of off-tape and input
signals) to outputs 7 and 8. These outputs are paral-
leled on the AES/EBU and TDIF-1 digital outputs
(though only one of these can be selected at one
time) as well as on any optional slot boards fitted to
the DA-98HR.
NOTE
Turning on confidence mode unarms any tracks which have
been armed prior to turning on confidence mode.
1 Pressing the REC FUNCTION of either track 3
or track 4, for instance, will arm both tracks 3
and 4(provided these are base-frequency
tracks).
In this way, a rough stereo mix, with channel level
and pan, and a master level, can be produced without
the need for a mixing console (for example, the AES/
EBU outputs can be used to feed a DAT recorder,
whose headphone amplifier is then used as the moni-
toring source).
2 Pressing either track 3 or track 4’s REC FUNC-
TION key will unarm both tracks (regardless of
which track’s REC FUNCTION key was used to
arm the tracks).
3 If confidence mode is turned off, track arming
and unarming can now be carried out on a
track-by-track basis.
5.4.1 Turning on the MIXDOWN mode
The mixdown mode is turned on and off using the
mixdown is in operation, and signals will only be
received at the 7 and 8 output channels.
Even if tracks were armed in pairs while confi-
dence mode was enabled, when confidence
mode is disabled, they can now be unarmed
individually.
NOTE
The mixdown function is only available when all eight
tracks have been selected at the base frequency (44.1 kHz
or 48 kHz).
5.3.2 Using confidence mode

Before you use a tape in the DA-98HR, you must
first format it. This marks internal synchronization
patterns for the servo to follow on subsequent passes
through the tape as well as the subcode data (ABS).
No audio data is normally recorded during a format-
ting operation (but see below).

When formatting, the tape is prepared for use in HR
(high-resolution; 24-bit) or normal mode (16-bit res-
olution).
Note that all sampling frequencies are related to a
base frequency, which may be either 44.1 kHz or
48 kHz. It is not possible to mix sampling frequen-
cies based on different base frequencies on the same
tape.
The formatting operation also determines the sam-
pling frequency or sampling frequencies that will be
used on the tape, and hence, the number of available

AES/EBU data.
NOTE
Once you have started to format a tape, it is strongly sug-
gested that you allow the format process to continue to the
end of the tape. Changing the sampling frequencies, the
number of tracks, or the recording resolution in the middle
of the tape will almost certainly lead to problems later on.
Even if you do not change any of these parameters, but
stop and start the tape in the middle of a format process,
there will be a discontinuity which will produce unpredict-
able results if you attempt to record over it.

If you have recorded and formatted part of a tape, and you

blank section of the tape and resume formatting and
recording from there.

6.3.2 Selecting the digital source
The DA-98HR has two built-in digital input sources:
for AES/EBU and TDIF-1 format data. Each of these
connectors can accept and output eight channels of
base-frequency audio. Either of these inputs can be
selected:
With a digital recorder such as the DA-98HR, track

1kHz). For this reason, you do not have to worry so
much about the constraints of choosing physical
track locations as you do with analog recordings.

Note that this function can also be used for track
copying later in the recording process. Remember
that track copying in the digital domain will add no
noise or distortion. A digital copy is a “clone” of the
original, and no loss of quality is incurred.
Note that this only selects the source—digital signals
are always output from both the TDIF-1 and the
AES/EBU connectors.
6.3.4 Write-protecting cassettes
If you attempt to record on a cassette where the
write-protect tab has been closed, an error message
will appear on the screen as you press the RECORD
key. Recording is, of course, not possible on a write-
protected cassette.
6.3.3 Selecting input sources
The DA-98HR contains a flexible input patchbay,
which allows signal sources to be selected between
digital, analog (if the optional IF-AN98HR slot board
set has been installed), recorded tracks on the tape
(for track bouncing), and muting.

You can repeat playback continuously between the

Track delay
The DA-98HR allows you to delay tracks relative to
the other tracks, either when recording or playing
back. You can use this function for post-production
“slip”, compensate for delays caused by external pro-
cessing equipment, allow for propagation delay in
multi-microphone sessions or add special effects.
NOTE
When we talk about the “first” and the “second” locations
here, we are referring to the earlier and later location times.
Memo 1 could be at a later time than Memo 2, and hence
we refer to it in this section as the “second location point”.
In repeat mode, the tape winds to a little before the
first point (if it is not there already) and starts play-
ing. Repeat playback (and hence tape monitoring)
starts at the first memory location and continues until
the second location is reached. The tape then stops
playing, and rewinds to a little before the first point
and starts playing again.
The track delay can be set from –200 samples to
+7200 samples. A negative number means that the
track on which the “delay” setting is made is
advanced in time relative to the other tracks. How-
ever, this does not mean that the DA-98HR includes a
time machine! Since the monitoring head is a “vir-
tual” head, made of a composite of input source sig-
nals and delayed signals from tape, the “position” of
the recording head can be adjusted in both directions.
7.2.6 To start repeat play
1 When the two location points have been set,
The track delay, expressed in seconds, is between –4
to +150 milliseconds. At a typical sound propagation
rate, the maximum value corresponds to about 50
meters (about 160 feet) of distance.

Consult your TASCAM distributor dealer for details
of other interface units or optional slot boards for the

ment (e.g. the IF-88SD which allows conversion
between SDIF-2 and TDIF-1 formats).
7.9
Sine oscillator
The DA-98HR should be connected to other TDIF-1
equipment using a PW-88D or PW-88DL connector
cable.
The DA-98HR incorporates a digital oscillator for
lineup and signal tracing purposes. This oscillator is
a sine-wave oscillator at either the standard tuning
frequency of 440Hz or the standard tape line-up fre-
quency of 1kHz.
NOTE
Only use TASCAM digital cables when making digital audio
connections to the DA-98HR. Other types of cable may
cause damage to the system, and the warranty will be
voided if such damage is caused by use of the wrong
cables.
The oscillator signal level is at the nominal signal
level of +4dBu (but note that since the oscillator is a
constant sine wave, it cannot truly be compared with
“real-world” transient signals).
Make sure that the DA-98HR’s word sync clock mas-
ter or slave setting is correctly made when it is con-
nected to other digital equipment. There can only be
one word clock master in a setup.
To operate the oscillator:
1 Enter menu 2, move the cursor to Sine
Osc.and press ENTER:
Since the TDIF-1 format carries a word clock as part
of the interface, there is no need to make a word
clock connection when recording through the DIGI-
TAL I/O connector if the TDIF-equipped devices are
the only digital audio devices in the setup. If there are
other digital audio devices present, make sure that
the word sync clock is properly setup throughout the
device chain.

7.12 Dither
If the setting is made to anything other than

Dither is the technique of adding a known noise to
low-level signals, especially when converting from a
high number of bits (for instance 24 or 20 input bits,
as in the case of the DA-98HR) to a lower number
(for instance 16 when the DA-98HR is recording in
standard mode) to improve quantization.
7.13 Output word length
The DA-98HR can output digital audio data at either
24 bit (if the recording has been made in HR mode)
or 16-bit resolution.
Paradoxically, this technique of adding noise
removes quantization noise and distortion at low sig-
nal levels and improves the overall distortion

Though quantization noise is reduced, there is a loss
of a few dB in the signal-to-noise ratio. For this rea-
son, the DA-98HR does not implement dither as a
standard, but allows you to choose between no dither,
rectangular or triangular (the shapes refer to the dis-
tribution of values in the digital noise). Rectangular
gives about 3dB better signal-to-noise ratio than tri-
angular, but there is noise modulation, which may be

By default, when there are many playback errors, the

that playback errors are audible.
Dither can be turned on and off while recording is taking

the sound quality. We suggest making a test recording
before a session using confidence mode. In this way you
will be able to make an instant assessment of the effects of
the different dither settings on your program material.

8 – DTRS synchronization
possible to match dual- and quad-frequency tracks with
base-frequency tracks in a chain, provided that they all use
the same base frequency (44.1 kHz or 48 kHz).
This section describes the techniques and methods to
be followed when the DA-98HR is linked to other
DTRS units (e.g. TASCAM DA-38, DA-88, DA-98,
DA-78HR, and of course other DA-98HR units).
The synchronization connections form a “daisy-
chain”, with the master unit at the head of the chain,
and the last slave at the tail.
In addition to control by a master DTRS unit, the a
chain of DA-98HR and other DTRS units can be con-
trolled by a remote control unit (for example, the RC-
898 remote control unit), or the control functions on
one of the TASCAM TM-D series of digital mixing
consoles. In these cases, the remote control device
should be connected to the REMOTE IN/SYNC IN
of the master unit. Machine IDs are unaffected by
this type of control.
You do not need to change the CLOCK setting from
any of the units if the system is a DTRS-only system.
NOTE
Always make and break all synchronization connections
with the power to all units in the chain turned OFF.
Up to 16 DTRS units can be linked, for a total of 128
digital tracks.
If you are connecting DTRS units of different types
to the DA-98HR, use the DA-98HR as the master
unit and the other units as slave units.
8.2
Machine ID and master/slave
settings
Each DTRS unit in the chain must be assigned a
unique machine ID. The unit at the head of the chain
(the master) should have ID number 1.
8.1
Synchronization
connections
Though not strictly necessary, we suggest that IDs
are assigned in a consecutive sequential order from
the head of the chain.
used when connecting the DA-98HR to other DTRS
units for synchronization purposes should be a PW-
88S cable. This is 1 meter (3 ft.) long.
8.2.1 Differences between DTRS
models
NOTE
Be sure to use only the optional PW-88S sync cables. The
use of any other cables could damage the DA-98HR.
The DA-98HR, DA-78HR, DA-98 and DA-38 all use
machine IDs that are set by software (the machine
must be turned on for the ID to be set). The values for
the IDs of these models start at “1” and go up to
“16”.
Be sure to connect the termination plug that comes with
the PW-88S cable to the last slave’s SYNC OUT connec-
tor , or else incorrect functions may occur.
Turn on all the DTRS units in your system, regardless of
whether you actually use all of them. A unit or units turned
off will make synchronization impossible.
The switch on the back of the DA-88 is only opera-
tive when the unit is turned off. It is marked from “0”
through “F”.
To synchronize multiple DTRS units, use a pre-formatted
tape in the master unit, and also in the slave units. Since
the DTRS system uses ABS time to achieve synchroniza-
tion, tapes without ABS time recorded on them make syn-
chronization impossible.
When including DA-88s and other DTRS units in the
same chain, add 1 to the number shown on the DA-
88’s rear panel machine ID switch to make the DA-
88’s machine ID match the series of the DA-98HR
(and DA-38) IDs. Any DA-88 whose Machine ID is
not 1 (the switch has been set to a value other than 0)
will show its Slave ID briefly at power-on.
To synchronize multiple DTRS units, all the tapes in each
unit must be formatted using the same base sampling fre-
quency, or synchronization is impossible. It is, however,

It therefore makes sense to set the machine IDs of all
DA-88s in the chain first, immediately after connec-
tions have been made with the power off, and then
turn on power to all units before setting the machine
IDs of all other DTRS units in the chain.
When a slave unit is locked to the master unit,
its CHASE indicator lights steadily.

original (also bear in mind that the media used by
DTRS units is relatively low-cost, so making back-
ups is in all ways a painless procedure).

TASCAM DA-98HR 55
9 – Operations related to timecode
The DA-98HR contains synchronization facilities,
including a timecode generator, which allow it to act
either as a timecode master or a timecode slave.
The timecode may be internally generated or
received from an external source. It can be SMPTE/
EBU, received and transmitted via the TIME CODE
timecode synthesized from the ABS subcode (9.2,
If timecode is recorded, a special discrete subcode
track is used, leaving all eight tracks free for record-
ing and playback of audio material.
Whether the SMPTE/EBU timecode is generated or
synthesized, we will refer to it as “timecode” in this
manual, to distinguish it from ABS timing values.
However, the DA-98HR is able to synchronize with
external timecode devices, even if the DA-98HR tape
has not been striped, by converting its internal servo
subcode (ABS) to timecode “on-the-fly”. We refer to
this as “synthesizing” timecode.
SMPTE/EBU timecode can be re-produced indepen-
dently of ABS timings and can be of any frame for-
mat supported by common timecode standards.
A full range of options is provided for full compati-
bility with the widest possible range of equipment.
When multiple DTRS units are connected, and the
master unit’s CHASE mode is set on, the master will
chase to any incoming timecode, regardless of
whether timecode or ABS timings have been selected
9.1
ABS and SMPTE/EBU
timecode
In some menus, by the time value, you may see either
ABSor TC. Here, we explain these two different
timing reference methods and the differences
between them.
Timing information received and transmitted from
and to external controllers (e.g. RS-422, MIDI or
Bus) will always be referenced to timecode values.
When the DA-98HR is referenced to its absolute
timecode, the ABS indicator to the left of the tape
counter will light, and when referenced to timecode
(internal or external), the TC indicator will light.
9.1.1 ABS time
“ABS” stands for “Absolute”, and is the absolute
time of the tape as recorded on the subcode of the
tape. This timing starts at the beginning of the tape
with a value of 00:00:00:00. This is the timing refer-
ence used when the DA-98HR is not using SMPTE/
EBU timecode.
9.1.3 Selecting TC or ABS timing
NOTE
This procedure is fundamental to synchronization opera-
tions. If you select the ABS timing mode when you want to
synchronize with timecode, you will be unable to synchro-
nize the DA-98HR.
Timecode (whether SMPTE or EBU) contains a fixed
number of frames per second. However, the ABS
method of timing works in a slightly different way.
To change between the two different time reference
modes, perform the following procedure:
In three seconds of time, there are 100 frames. These
frames are allocated as follows:

This pattern is repeated every three seconds, as you
will notice when you set frame values using the menu
system in ABS mode. When multiple DTRS units are
connected together in DTRS sync mode, the master
unit always outputs ABS timings to the slave unit(s).
2 Use the § and ¶ keys to select either ABS
(absolute) or TC(timecode).
The appropriate indicator to the left of the
tape counter (either ABS or TC) will light.

This is the one setting in this menu which does not
use the ABS conversion facility. You should only use
this setting if you are using the dedicated timecode
track with recorded timecode (either from an external
source, from the DA-98HR’s own internal generator
or synthesized or assembled from ABS).
You can also enter a time offset directly using
The time you enter is the time at which the timecode
starts from the beginning of the tape. For instance, if
you enter an offset of 00:59:00:00, and the tape
is positioned exactly 1 minute after the start, the
timecode is 01:00:00:00.
If you have selected TcTrackin the menu

tion is performed, allowing you to locate each track
easily with reference to the timecode values.

9.3.5 External timecode sources
The following notes should help you when you have
no alternative but to record timecode on the DA-

9.3.6 Recording timecode from an
analog recorder
If external timecode has been received since the DA-
98HR has been switched on, but is not currently
being received, the tape counter will flash.
When recording timecode from an analog recorder,
feed the analog recorder or its external synchronizer
and the DA-98HR with a common video source, and
use the video resolve function of the analog recorder
or synchronizer, if this is provided.
If the external timecode is currently being received at
normal (play) speed, the tape counter will show the
value of the timecode currently being received. If the
external timecode is being received from a source in
fast wind mode, the tape counter will flash.
If the analog recorder has no video resolve function,
it may have a timecode chase function, which can be
driven by any timecode source from the following
list:
If the timecode source is not clock-synchronized
with the DA-98HR, a warning will be shown on the
display screen. In this case, although you can record
timecode, it is not recommended, as this will proba-
bly cause problems later on.

or reset it to a point prior to where you want
recording to begin. The tape counter now
starts to flash.

Timecode is recorded from the external source
onto the timecode track.
If your analog recorder cannot chase to external time-
code, you must first record the timecode from the
analog recorder on an audio track of the DA-98HR
and then transfer the timecode to the dedicated time-
code track.

9.3.8 Checking external timecode
9.4.1 Pull up and pull down (Fs shift)
External timecode can also be checked in another
way, as described below. This method is useful for
checking the frame rate of incoming timecode, if you
are not sure what frame rate has been recorded or is
being generated by the timecode source.
When working in film post-production with NTSC
telecine equipment, the frame rate of film (24 fps)
and the NTSC color frame rate (29.97) do not form a
simple mathematical ratio, and the sampling frequen-
cies of either 44.1kHz and 48kHz are therefore
affected on transfer back to film.

When using the DA-98HR to chase to a timecode
master, the system frame rate on the DA-98HR must
match the frame rate of the timecode master, other-
wise chase operations are not possible.
The clock source must be set to INT when using the Fs
shift function to pull up, and to VIDEO when using this
function to pull down.

which has been striped with timecode is inserted, or
if power is switched on with a striped tape already
inserted in the unit. The frame rate recorded on the
tape is then used as the system frame rate.

when the DA-98HR is to record timecode from
The 05 Framesetting means that timecode
information is not output continuously. Here, the
DA-98HR reads the timecode from the tape as it is

from tape, then reads the tape again, outputs another
5 consecutive frames based on the new tape position,
and so on.

9.5.5 Using MIDI Time Code (MTC)
The DA-98HR can output MIDI Time Code in
almost exactly the same way as it outputs audio time-
code, with the following exceptions.
However, when a DA-98HR unit has its machine ID
set to a value other than 1, there is a conflict when the
CHASE key is pressed. You must determine whether
the chase mode refers to timecode or to the DTRS
sync, and this is done using the Time Mode menu
selected, when CHASE is pressed, the machine will
enter DTRS sync mode, but if TCis selected, the
machine attempts to lock to external timecode.

MIDI Time Code can be output either when the DA-
98HR is playing, or in fast forward or rewind, or
when stopped. You can turn off the output during the
“fast” modes and while stopped, to avoid overloading
a MIDI data stream.
When the DA-98HR is in “chase-ready” mode (the
CHASE indicator is flashing) and timecode is
received at the TIME CODE IN connector, the DA-
98HR starts to chase the timecode. When it is locked
to the incoming timecode, the CHASE indicator
lights steadily.

Note that the DA-98HR cannot accept MIDI timecode, and
therefore cannot chase to MTC.
The exact ways in which it chases the timecode and
handles transport functions, etc. are determined by a
number of settings, as described below:

Chasing to timecode
9.6.2 Setting timecode offset
The following sections describe the operation of the
DA-98HR when chasing to external timecode.
You may enter a timecode offset for the audio from
the DA-98HR to match the audio (or video sequence)
from the timecode master.
The operation of the CHASE switch is similar to the
way the CHASE switch is used when synchronizing

you can either set this manually, entering the num-
bers, or set it “on-the-fly” by ear. In either case, once
the offset has been entered, it can then be edited.
9.6.1 Machine ID and timecode
Since a DA-98HR with machine ID set to 1 is always
a master unit as regards DTRS sync operation, there
is no need to make any setting on such a machine if it
is to be a timecode slave. As long as timecode is

9.6.7 Park position
When the DA-98HR is slaved to an external time-
code source, it will take some time between the mas-
ter unit starting to play and starting to transmit
timecode for the DA-98HR to read.
9.6.4 Cancelling timecode offset
When the timecode offset value is set to all zeros,
timecode offset is cancelled and the OFFSET indica-
tor goes out.
These functions allow you to measure and test the
optimum pre-roll position for the DA-98HR (when it
is a timecode slave) to park itself relative to the mas-
ter timecode device so that it will lock up and start
playing quickly.

code will be captured and stored as the timecode off-
set (either a positive or negative value).

can automatically determine the optimum park pre-
roll position to sync with the master.

When timecode is received, the DA-98HR can either

While the DA-98HR is re-syncing (speeding up and

unless the clock is set to INT). Usually you should
find that the DA-98HR does not need to rechase,
however, and you can leave it in free-running mode.
If the timecode master tape includes a break in the
timecode, though, you may want the DA-98HR to

As explained above, if the DA-98HR is to be syn-
chronized with a VTR, all units must share a com-
mon video reference for the digital audio clocks,
generated either by the VTR or from a sync genera-
tor.
9.6.11 Bypassing timecode errors
As timecode is received from a remote master unit, it
may be subject to errors (dropouts on the timecode
master tape, etc.). These errors can cause synchroni-
zation failure (the DA-98HR will no longer be locked
to the timecode of the master unit).
As well as the sample clock, the timecode can be ref-
erenced to a video clock (i.e. the start of each time-
code frame is synchronized with each frame
boundary received at the VIDEO IN terminal) or can
be independent of the received frame clock.
You can set the DA-98HR to bypass and ignore
incoming timecode errors of up to 30 frames in
length, or up to 10 frames in length.
Additionally, in a similar way to timecode rechase
can be set to rechase the video frame sync (muting
playback output as it rechases), or to run freely once
sync is achieved, ignoring any breaks in the received
video signal.

This delay is also used for controlling the timing of the mon-

There are two basic methods for locating which are
used by controllers. The first method is to send a
locate command. The second is to send fast wind and
shuttle commands.
The delay is calculated in the following way: the first
frame boundary of the video signal received at the
VIDEO IN after the record command is received is
counted as”1”. This number is incremented as subse-
quent frames are received, and when it equals the
record delay value as set above, recording starts.
If the usual high speed winding of the DA-98HR is
used with the second method, the tape will almost
invariably overshoot each time and never come to
rest. For that reason, you can select between the fast
wind modes (at 100 times play speed) and fast shuttle

10.3.6 Track mapping
When a controller arms and records on tracks, you
need to specify which tracks on the controller corre-
spond to particular tracks on the DA-98HR. The
video controller protocol allows for control of up to
eight digital and four analog audio tracks. The setting
described here allows you to map controller tracks to
DA-98HR tracks.
1 1 2 2 3 3 4 4
This mapping does not imply any correspondence
between the user interface of the controller and the
DA-98HR tracks—it refers to the relationship
between the command signals transmitted by the
controller and the DA-98HR tracks. The relationship
between the user interface of the controller and the
command signals must be determined using the con-
troller itself.
1 2 3 4 1 2 3 4

There are no user-settable track mappings, but these
pre-set mappings are designed to cover almost every
set of circumstances.
NOTE
10.3.7 Timecode track mapping
Not all eight tracks may be available , depending on the
able tracks will simply be ignored.
This is a special instance of track mapping, where the
track corresponding to analog track 3 in the control-
ler’s command signals is mapped either to the digital

Each DA-98HR must be assigned a unique number

the commands which are available.
10.4.1 Assigning a MIDI and Bus ID to
the DA-98HR
A MIDI ID is used in a MIDI Machine Control setup
to identify each unit in the MIDI chain. The same
number is also used as a Bus identifier.
10.5.1 MMC and the DA-98HR
An example of a MIDI sequencer being used to con-
trol a DA-98HR (using the auto-punch of the
sequencer to punch in and out on the DA-98HR
tracks) is given below. Note that the sequencing soft-

to it as a “channel number”), and is not connected

ware must be able to transmit MMC commands and
also to sync to MTC for this to be effective:
The sequencer is set up to transmit MMC commands,
and is set so that it synchronizes to SMPTE/MTC.
When a “transport” command is given from the
sequencer, the appropriate MMC command is trans-
mitted to the DA-98HR. When the DA-98HR has
located and starts playback (or recording), the MTC
is transmitted back to the sequencer, which locks in
and starts at the correct point.

(MTC)
In this way, though the DA-98HR is the timecode
master, the sequencer is the transport master.
The arrangement shown here uses two inputs to the
sequencer. The same effect could be achieved with
the intelligent use of filtering mechanisms and one
input to the sequencer.

12 – Maintenance and settings
on page 84 below for details of how to check head
usage time.
12.1 Head and transport cleaning
Every 350 to
400 hours
Perform manual cleaning of heads and
guides as described below. Check the
tape path alignment after cleaning. This
requires proper test and measurement
equipment, and should be performed only
by qualified service personnel.
The DA-98HR incorporates an internal cleaning
mechanism that not only cleans the rotary head, but
also the tape as it enters the tape path. The provision
of this cleaning mechanism significantly reduces the
need for manual cleaning.
Every 1000
hours (every
third cleaning)
A complete alignment check should be
performed.
However, before recording in HR mode, because of
the high bit density, dirty heads can have a significant
effect on recording and playback. We therefore sug-
gest a daily cleaning procedure as described below:
The above cleaning cycle timings are based on the
assumption that the DA-98HR is being operated in a
clean environment. A dusty or smoky atmosphere
will shorten the time between cleaning operations
12.1.1 Daily cleaning
If this unit is used for HR recording, we suggest a
daily cleaning of the heads. However, take note that
excessive head cleaning may cause abrasion of the
heads.
NOTE
Most name brand tapes are of very high quality. However, it
is sometimes possible to receive “bad” stock which exhibits
excessive shedding characteristics. If you receive such
tape stock, stop using it immediately, and follow the clean-
ing procedure as described below.
To clean the heads when recording in HR mode:
1 Before inserting the tape to be used for record-
ing, insert a suitable cleaning tape (such as the
TEAC HC-8).
1 Select menu group 9, move the cursor to
Cleaning, and press ENTER:
2 As the cleaning tape is loaded, the display
shows --LoAd, followed by E Hi8t(E
Hi8T), and the cleaning tape is then automati-
cally ejected.
Cleaning Mode
This method of cleaning the heads causes mini-
mum abrasion.
Count:0001
off
2 Press the § or ¶ key to set the cleaning mode
to on. If a tape is loaded, it is automatically
ejected.
If, despite the internal cleaning mechanism and this
daily cleaning operation, the PB CONDITION indica-
manual cleaning procedures below should be
followed.
3 Insert the cleaning tape.
4 The cleaning tape “plays” for about two sec-
onds and then is automatically ejected. The
cleaning counter (number of times the heads
have been cleaned) is incremented by one.
12.1.2 Periodic cleaning
Use a TEAC HC-8 cleaning tape (as supplied with
the unit, and recommended) or a dry cleaning tape
specially designed for Hi8 8mm video equipment.
NOTE
Note the following points:
NOTE
S
Do not attempt to rewind or fast forward the cleaning tape,
either in the DA-98HR or in a video unit. Simply insert it into
the DA-98HR when you use it the next time.
NEVER use a wet-type cleaning tape, as this will result in
winding problems.
The use of the dry tape will reduce the head life of the DA-
98HR by about five hours. Use of manual cleaning is there-
fore discouraged.
Excessive cleaning can cause excessive wear on the
heads. Do not clean the heads too frequently, and never
perform the head cleaning procedure more than 5 times
running.
We recommend the following schedule (based on our
experience with the DTRS system) for cleaning and
maintenance schedules. See “Checking head time”
In addition to cleaning the heads, we recommend that you
have the DA-98HR checked by an authorized TASCAM
service technician every 500 hours or so of use.
TASCAM DA-98HR 83
12 – Maintenance and settings–Checking error rates
Also, before using an ME tape for archival or one-time
tion of the difference between tape types), we suggest that
you clean the heads, as described here.
NOTE
If, after trying different tapes and cleaning the heads, you
still see many errors, you should contact a TASCAM ser-
vice technician to check your DA-98HR.
12.2.1 Checking head time
12.2 Checking error rates
This function allows you to check the number of
hours that the head has been used in play or record
mode.
If you hear noise and distortion on playback, even
after cleaning the heads, or if you are presented with
a tape of dubious quality, you may want to check the
error rate of the tape.
1 Select menu group F, and move the cursor to
Dr Total. The number of whole hours
that the head has been in use is shown on the
bottom line of the display.
You can check the error rates at four tape track posi-
tions, for each of the two heads (A and B) with two
audio channels in each position:

12.3 Memory backup
It is inevitable that there will be a few errors,
but if the display consists mainly of solid
blocks while the tape is playing, something is
wrong (and you will almost certainly be able to
hear it!).
The DA-98HR incorporates battery-backed memory
which preserves almost all user settings after the
power is turned off.
Settings can also be stored to one of three user RAM
memories, meaning that even when settings are
changed between sessions, the previous settings can
be recalled. Factory settings are also recallable in the
same way.
Use this display to show where the tape is in
error, and which head is causing errors. In this
way, you can pinpoint the cause of trouble.
If playing another tape seems to remove the
errors, the problem is with the tape, otherwise
clean the heads more than 5 times in a row.
In addition, the user settings for a particular session
can be stored on tape and later reloaded. This enables
a tape to be transported between locations and
replayed on another unit with the minimum of setup
time.

setup memory banks: 1, 2 or 3. This enables pre-con-
figuration of the DA-98HR for different jobs (video
or film post-production, or different recording setups,
for example). There is also a preset memory bank
which contains the factory settings (see below).

ation. The tape rewinds to the start of the ABS
code, records the settings, rewinds and verifies
that the settings have been correctly written to
tape.
The DA-98HR saves the user parameters to tape
using the first few seconds of the tape after the ABS
00 00 00 00position. This is entirely indepen-
dent of any audio data written at this position, and the
same part of the tape may safely be used for user data
settings and for audio.
The display shows donewhen this is per-
formed with no errors, otherwise an error mes-
sage is displayed.
The following settings are not saved to tape. When a
set of parameters is loaded from tape, these are reset
to the default values, as listed here:

12.6.1 Software upgrades
TASCAM pursues a policy of continuous improve-
ment to products, and there may be future enhance-
ments to the DA-98HR software. Your TASCAM
dealer will be able to advise you of developments in
this area.
TASCAM DA-98HR 87
13 – Options/specifications/reference
• If a remote control unit is used, it should be con-
nected to the DA-98HR’s REMOTE IN/SYNC IN
13.1 DA-98HR options
You can purchase a number of options through your
TASCAM dealer.
• Up to 6 DTRS units can be controlled using one
RC-898 controller. The first unit in the chain
should be a DA-98HR.
These include the IF-AN98HR interface boards,
allowing high-quality 24-bit conversion between the
analog and digital domains. These boards may be fit-
ted in the option slots of the DA-98HR.
• The first DTRS unit in the chain should be given
Machine ID 1 (ID 0 for DA-88 units), even when a
remote control unit is used.
• The last DTRS unit in the chain (even if it is the
only one) must be terminated at the SYNC OUT

13.1.1 Accuride® mounting
The DA-98HR is fitted with screw holes in the case
which allow you to fit Accuride 200 series guide rails
(20”) which also help with removing and replacing
the DA-98HR from and to rack installations.
13.1.3 Meter unit (MU-8824)
The optional MU-8824 external meter bridge unit
can be connected using a PW-88M cable from the
Accuride strips are fitted as shown below:
The meter can be rack mounted using the RM-8824
rack mount angle accessory or mounted on the RC-
898 using the MK-9824 mounting kit.
No settings are necessary on the DA-98HR to use
this meter unit.
13.1.4 Cables
As mentioned earlier, TASCAM cannot accept any
responsibility for damage caused by the use of the
wrong cables.
Make sure that all screws and bolts are securely tight-
ened before replacing the DA-98HR in the rack.
Always consult your TASCAM dealer to see if there
is a ready-made cable to meet your needs. The TAS-
CAM cables to be used with the DA-98HR (at the
time of writing this manual) are given in the table
below:
13.1.2 Remote control units (RC-898,
RC-848 and RC-828)

13.5 MIDI Control Change
These TASCAM Exclusive messages are developed
for controlling DTRS recorders connected to each
other via the SYNC IN connections.
It is possible to send use MIDI Control Change mes-
sages to control the sub-mixer parameters, as
described here:
The messages follow the following format:

checksum — lower 7 bits of the sum of all num-
bers from (and including) <cc> up to <cs>
MIDI channels 1 through 8 control channels 1
through 8 on the master DA-98HR in a DTRS chain.
MIDI channels 9 through 16 can be used to control
channels 1 through 8 on the first slave DA-98HR in a
chain.
