TASCAM IF-AE8HR
1
Introduction
The TASCAM IF-AE8HR provides a convenient way
of exchanging digital audio data between TDIF-1-
equipped devices, such as DTRS recorders, and AES/
EBU devices.
AES (professional—PRO) or as IEC-60958 TYPE II
(SPDIF—CONSUMER).
Consumer and professional formats received at the
XLR-type inputs are automatically distinguished by
the unit.
A single TDIF-1 connector carries eight channels of
digital input and output. Four XLR-type connectors
accept four two-channel input signals, and another
four XLR-type connectors output four two-channel
input signals.
1.1 Mounting, etc.
The IF-AE8HR is a 1U unit, designed to fit into a
standard 19-inch rack.
The word synchronization is selectable, using a front
panel switch, from any of the four XLR-type inputs,
from the TDIF-1 source, or from an external inde-
pendent word clock source.
Included in the package are;
• The unit itself
• This manual
• A rack-mounting kit
• A 2 m (6 ft.) power cord
• Four rubber feet
The IF-AE8HR allows high-resolution (up to 24 bits)
audio data to be transferred between units. No set-
tings are necessary to set word length.
If any of these items are missing, contact your TAS-
CAM distributor.
In addition, four channels of high-frequency audio
data at 88.2 kHz or 96 kHz may be selected from the
front panel and transferred using the IF-AE8HR.
Install the unit in the 19” rack as shown below:
Separate word clock outputs are provided for either
high-frequency or normal-frequency data clocks.
When a high-frequency data rate (88.2 or 96) is
selected, the IF-AE8HR provides a choice of how the
data is physically transmitted: either using a single
high-speed connection (HI SPEED) or two parallel
“normal” speed connections (DUAL).
The audio data format output from the XLR-type
outputs may be selected from the front panel as either

1 Power switch and indicator
Push the POWER switch once to turn on power, and
again to turn it off. The POWER indicator lights
when power is supplied to the IF-AE8HR.
2 LOCK indicator
When a valid clock signal is received at the selected
clock source, this indicator will light.
Note that settings made are not memorized. When-
ever the power is turned on, the CLOCK source is set
to WORD 3, the SAMPLING FREQUENCY is set to
If this indicator starts to flash, the IF-AE8HR is not
locked to the external clock (as specified by 3). This

occurs if there is no clock signal or the signal is ±6%
outside the nominal frequency. In these cases, once a
valid clock signal is received again, the indicator will
light steadily.
DUAL mode (Fs=88.2k or 96k)
Data is transferred in over two channels in the DUAL
mode. In high-frequency sampling modes (88.2k and
96k), there is twice the amount of data compared to
the usual modes (44k and 48k). In DUAL mode, one
XLR-type connector carries the data for one channel,
allowing four channels in total to be transferred.
3 CLOCK switch and indicators
This switch allows you to cycle between the six pos-
sible clock sources for the IF-AE8HR: the WORD
SYNC – IN 9 connector, the DIGITAL I/O (TDIF-1)
8 connector, or any of the four two-channel AES/
EBU connectors (DIGITAL I/O (AES/EBU) INPUTS
(1/2, 3/4, 5/6, 7/8) 7), as shown by the indicators to
the right of the switch.
In this mode, channel 1 is carried by connector 1-2,
channel 2 by connector 3-4, channel 3 by connector
5-6, and channel 4 by connector 7-8.
HI SPEED mode (Fs=88.2k or 96k)
In the HI SPEED mode, data is transferred at double
speed. As mentioned above, in high-frequency sam-
pling modes (88.2k and 96k), there is twice the
amount of data compared to the usual modes (44.1k
and 48k). Here, the transfer speed is doubled, so that
one connector can carry two channels’ data.
NOTE
There should usually never be more than one word clock
signal in a digital audio system. If there is more than one
word clock, at worst, damage may occur to speakers,
amplifiers, etc. as a result of high-frequency noise gener-
ated by word clock incompatibilities, etc..
In theory, this would allow eight channels to be trans-
ferred at high speed, but for the reason below, only
four channels may be transferred using the IF-
AE8HR.
4 SAMPLING FREQUENCY switch and
indicators
This switch allows you to select the sampling fre-
quency at which the IF-AE8HR outputs data, either
to the XLR-type connectors, or to the TDIF-1 con-
nector: 44.1k, 48k, 88.2k or 96k.
NOTE
NOTE
In TDIF version 2 format, only the DUAL mode is sup-
ported. If HI SPEED is selected, only DIGITAL I/O
(AES/EBU) connectors 1-2 and 5-6 are used. Therefore,
INPUT and OUTPUT terminals 3-4 and 7-8 cannot be
used in this mode.
There are also two other settings that may be selected
with this switch: DUAL and HI SPEED, which only
become options when one of the high-frequency
options (96k or 88.2k) has been selected. Repeated
presses of this switch will cycle between the follow-
ing settings:
Error modes
These LEDs are also used as error indicators, to show
an error condition with regard to the input signals.
The selected frequency indicator will flash to show
an error under the following circumstances. When
appropriate steps are taken to correct the problem, as
shown below, the indicator will stop flashing and will
light steadily.

Usual mode (FS=44.1 or 48)
In this mode, one XLR-type connector carries two
channels of data. Since the IF-AE8 is provided with
four such XLR-type connectors for input and four for
output, the data for eight channels can be transferred
in total.
• Incorrect data is being received at one of the AES/
EBU inputs. Make sure that all data sources are
correctly set up.

NOTE
If WORD is selected as the clock source, and a high-
frequency sampling frequency has been selected
(88.2k or 96k), but the incoming word sync clock is

shown by the PRO indicator flashing for about two
seconds, and then returning to a steadily-lit state.

Use this connector to connect a suitably-equipped
TDIF-1 digital audio unit (e.g. a DTRS recorder or a
TASCAM digital mixing console).
These balanced XLR-type connectors output digital
audio data in AES/EBU professional or in consumer
format, depending on the selection made with the
CHANNEL STATUS switch 5.
The signals received at this connector can be selected
as the word clock source using the CLOCK switch
3.
The sampling frequency of the output data depends
on the setting of the SAMPLING FREQUENCY
switch 4, and the currently-selected clock source
3.
NOTE
Note that you should always use genuine TASCAM cables,
or cables which have been approved for use with TDIF-1
interfaces by TASCAM.
7 DIGITAL I/O (AES/EBU) INPUTS
(1/2, 3/4, 5/6, 7/8)
Although these cables appear similar to certain types of
computer cables and use similar connectors, the cables
themselves are very different, and the different electrical
characteristics of the cables can cause damage to the
equipment connected with the wrong cables.
These balanced XLR-type connectors accept digital
audio data in AES/EBU professional or in consumer
format. The data type is automatically selected and
no setting is necessary.
If the use of cables other than TASCAM cables causes or
results in damage, the warranty is voided.
Note that there are four independent detection cir-
cuits, meaning that a mix of consumer and profes-
sional format signals may be input at these four
inputs. However, all the signals must be at the same
sampling frequency.
9 WORD SYNC – IN
The BNC connector accepts a word clock signal from
an external source. It can be selected as the word
clock source for the IF-AE8HR using the CLOCK
switch 3.
Also note that if a signal with emphasis is received at
any input, the resulting output signals will all contain
emphasis.
If a high-frequency sampling frequency (96k or
88.2k) has been selected, it is possible to use either
the appropriate high-frequency word clock, or the
corresponding standard-frequency word clock.
The signal received at any of these connectors can be
selected as the clock source for the IF-AE8HR using
the CLOCK switch 3

input at the WORD SYNC – IN connector 9.
These clocks output from B and C may or may not
be the same as the clock received at WORD SYNC –
IN 9 and retransmitted through WORD SYNC –
THRU (AUTO TERM) A. However, they are always
the word clock selected using the CLOCK switch 3.
If no connection is made to this connector, it is auto-
matically terminated.
B WORD SYNC – OUT (STD Fs)

This BNC connector outputs a standard-frequency
word clock: either 44.1 kHz when 44.1k or 88.2k is
selected, or 48 kHz when 48k or 96k is selected.
Use the supplied power cable to connect the IF-
AE8HR to the power supply. Always ensure that
your power supply matches the requirements marked
on the rear panel of the unit. If you are in any doubt,
consult a qualified electrician.
C WORD SYNC – OUT (HI Fs)
This BNC connector outputs a high-frequency word
clock: either 88.2 kHz when 44.1k or 88.2k is
selected, or 96 kHz when 48k or 96k is selected.
