1 – Introduction
The CD-RW4U CD rewritable recorder allows you to
make your own CDs from a variety of sources—
other CDs, MD recordings, analog cassette tapes, and
records.
A sampling frequency convertor is incorporated,
allowing the recording of CDs from digital audio
sources which are at frequencies other than the CD
standard sampling frequency of 44.1kHz.
In addition, the USB connector allows the CD-
RW4U to be connected to most modern personal
computers and used as a high-speed data CD-RW
drive, allowing easy archival of data to disc, as well
as the reading of commercial CD-ROMs.
Track divisions can be entered manually, or can pro-
duced automatically as a response to the input signal
level.
A recording buffer ensures that even the first milli-
seconds of a track are recorded.
Tracks can be recorded all at one time, or added, until
the disc is “finalized”, allowing it to be played on CD
players.
“One-touch” fade-ins and fade-outs over a specified
time allow you to edit program material to your spe-
cific requirements.
NOTE
A multi-function “multi dial” control is used to set
Some models of CD player may be unable to play certain
discs produced using the CD-RW4U.
and confirm parameter settings.
A cordless remote control unit allows control of the
CD-RW4U from remote locations.
A variety of sophisticated features are incorporated
in the CD-RW4U, allowing a wide degree of
flexibility.

1 – Introduction—Special notes
CDs either for playing or recording, even with a “sin-
gle” adaptor.
Environmental considerations
The CD-RW4U may be used in most areas, but to
maintain top performance, and prolong operating
life, observe the following environmental conditions:
sible problems with overheating. Also, you should
avoid placing anything on the unit while it is in oper-
ation, for the same reason.
The nominal temperature should be between 5°C and
35°C (41°F and 95°F). The CD-RW4U is more sensi-
tive to extremes of temperature than ordinary CD
players.
The voltage supplied to the unit should match the
voltage as printed on the rear panel. If you are in any
doubt regarding this matter, consult an electrician.
NOTE
Relative humidity should be 30 to 90 degrees non-
condensing.
When transporting the unit, always use the original packing
materials. For this reason, we strongly recommend that you
save all the packing materials that came with the CD-
RW4U, in case you need to transport it in the future.
As the unit may become hot during operation, always
leave sufficient space above the unit for ventilation.
In addition, when transporting the unit, you should tape the
disc tray closed, using an adhesive tape that will not spoil
the finish of the unit.
You should not place the unit on a piece of equip-
ment generating heat, e.g. an amplifier, to avoid pos-
Use of the remote control unit
When using the remote control unit, make sure:
• Always make sure that both batteries are replaced
together. Do not mix old and new batteries.
• There is a clear unobstructed path between the
main unit.
• Do not mix batteries of different types.
• Always make sure that the batteries are located
with the correct polarity (the positive terminals of
the batteries should match the + markings inside
the battery compartment, and the negative termi-
nals should match the – markings).
• The remote control unit is located within 5 m
(15 ft.) of the main unit, and is pointing at approxi-
mately right angles ( 30°) to the front panel.
When fitting or replacing the batteries:
• If you are not going to use the remote control unit
for an extended period of time, remove the batter-
ies. Old batteries can leak, casing damage to the
remote control unit.
• Always dispose of old batteries in the way recom-
mended by your local garbage disposal authorities.
Beware of condensation
If the unit (or a compact disc) is moved from a cold
to a warm place, or used after a sudden temperature
change, there is a danger of condensation; vapor in
the air could condense on the internal mechanism,
making correct operation impossible. To prevent this,
or if this occurs, leave the unit for one or two hours
with the power turned on, then turn the power off and
on again.
About CD-R and CD-RW discs
The CD-RW4U uses CD-R and CD-RW media, and
can also use CD-R and CD-RW Digital Audio media.
CD-R discs can be recorded once only. Once they
have been used for recording, they cannot be erased
or re-recorded. However, if space is available on the
disc, additional material can be recorded. The pack-
In this manual, when we refer to “CD-R” and CD-
RW” discs, we always include “CD-R Digital Audio”
and “CD-RW Digital Audio”, even when this is not
explicitly stated.

aging of CD-R discs will include one of the follow-
ing logos:
However, you should note that an audio CD created
using a CD-RW disc may not play back satisfactorily
on every audio CD player. It will, naturally, be play-
able on the CD-RW4U. This is in no way a limitation
of the CD-RW4U itself, but is a property of the dif-
ference between the different types of media and the
methods used to read them.
By contrast, a CD-RW disc can be used in much the
same way as a CD-R disc, but the last track or tracks
recorded can be erased before the disc has been
“finalized”, and the space on the disc can be re- used
for other recordings. The packaging of CD-RW discs
will include one of the following logos:
CD-R discs created on the CD-RW4U, by contrast,
may be played satisfactorily on the majority of audio

Handling of compact discs
Observe the following:
stains will have absolutely no effect on reproduc-
tion quality.
• Always place the compact discs in the trays with
their label facing upward (compact discs can only
be played on one side).
• To remove a disc from its storage case, press down
on the center of the case, and lift the disc out, hold-
ing it carefully by the edges.
• Never use such chemicals as record sprays, anti-
static sprays or fluid, benzine or thinner to clean
compact discs. Such chemicals will do irreparable
damage to the disc’s plastic surface.
• Discs should be returned to their cases after use to
avoid serious scratches that could cause the laser
pickup to “skip”.
• Don’t expose discs to direct sunlight or high
humidity and temperature for extended periods.
Long exposure to high temperature can warp the
disc.
• Finger marks and dust should be carefully wiped
off the disc’s recorded surface with a soft cloth.
Unlike conventional records, the compact disc has
no grooves to collect dust and microscopic debris,
so gently wiping with a soft cloth should remove
most particles.
• Only use circular compact discs. Avoid using non-
circular promotional, etc. discs.
• Wipe in a straight motion from the inside to the
outside of the disc. Small dust particles and light
• To keep the laser pickups clean, don’t touch them.
For the same reason, don’t leave the disc trays
opened unnecessarily.
Additional notes with regard to CD-R and CD-RW discs
There are additional precautions that you should take
when handling CD-R and CD-RW discs, that are dif-
ferent to those that you should take when handling
ordinary CDs.
• Avoid touching the recording (non-label) side of a
disc on which you will be recording. Recording on
a disc requires a cleaner surface than playing back,

1 – Introduction—Switching to audio mode
and fingerprints, grease, etc. can cause errors in the
recording process.
• When labeling CD-R discs, always use a soft oil-
based felt-tipped pen to write the information.
Never use a ball-point or hard-tipped pen, as this
may cause damage to the recorded side.
• CD-R discs are more sensitive to the effects of heat
and ultraviolet rays than ordinary CDs. It is impor-
tant that they are not stored in a location where
direct sunlight will fall on them, and which is away
from sources of heat such as radiators or heat-gen-
erating electrical devices.
• Dirty discs may be cleaned using a soft dry cloth
and/or a commercial CD cleaning fluid or ethyl
alcohol. Do not use thinner, gasoline, benzene or
LP cleaning fluid, as these will damage the disc.
• Always store CD-R discs in their “jewel cases” to
avoid dirt and dust accumulating on their surfaces.
• If you are in any doubt as to the care and handling
of a CD-R disc, read the precautions supplied with
the disc, or contact the disc manufacturer directly.
• Do not put labels or protective sheets on the discs
and do not use any protective coating spray.
Never use a stabilizer, printable discs or a single adapter
Using commercially available CD stabilizers or
printable recordable discs with this player will dam-
age the mechanism and cause it to malfunction.
NOTE
Never use a disc that has had a stabilizer mounted to it.
The residual adhesive may cause the disc to stick to the
mechanism of the CD-RW4U. If it sticks to the mechanism,
you will need a technician to get it out.
You should not use an 8cm (“single”) adapter when
using the CD-RW4U.

If the CD-RW4U is used to record a digital audio source
which is connected using analog connections, even if the
DDsetting above is made, the trigger level will automati-
cally be set to -54dB.
Also note these points when making digital recordings from

MIN L, DD, -24, -30, -36, -42, -
48, -54, -60, -66, and -72dB.
Since the DDsetting pays no attention to the sound level,
but only to received subcode, it is possible that when the
CD-RW4U is in record ready mode and a CD is selected as
the digital recording source, and the source CD is
changed, when the source player reads the TOC of the
source disc, when the first track is read, a spurious signal
will be sent to the CD-RW4U, which will start recording.
Low numerical values of this setting (towards –24)
mean that it takes a louder signal to trigger the start
of the synchronized recording. A high numerical
value (towards –72) means that a relatively quiet sig-
nal will trigger the start of recording.
Also, when a digitally-connected DAT is used as the
source, and the tape is wound fast (forward or backward) to
cue the source tape to the start of the desired track, you
should remember that START IDs will be sent from the DAT
deck while the fast wind is proceeding. These START IDs
will also trigger recording if the CD-RW4U is in record
ready mode, and the DDsetting is selected.
The MIN Lis a special case. It means that any
non-zero digital levels (that is, any sound over the
zero level) will act as the trigger signal. It also
applies to analog sounds passed through the AD
converter.
The DDsetting is also a special case. It is not a sig-
nal level, but refers to the start of a track, as encoded
in an SPDIF digital audio signal. It is therefore only
For these reasons, we suggest that you only switch on the
DDsetting when the source CD player or DAT deck is in
STOP mode.

Finalizing
Although audio data may be written on a CD-R or
CD-RW disc, a standard CD player will not be able
to read the data (i.e. play back the audio) until a final
table of contents (TOC) has been written at the start
of the disc.
In the case of a CD-RW disc which has been final-
ized, the whole of the disc may be erased, or the disc
may be “refreshed”, and the disc re-used.
In addition, a CD-RW disc that has been finalized
may be “unfinalized”, i.e. the TOC is removed. This
allows further tracks to be recorded to the disc, pro-
vided that there is space on the disc.
The process of writing this table of contents is known
as “finalizing”. Once this has been done, no further

4 – Recording
Before you start recording using the CD-RW4U,
make sure that you understand the following key
points:
• You can add tracks to an unfinalized recordable
disc. Once finalized, a CD-R disc is “fixed” and
behaves in the same way as a pre-recorded disc.
Finalized CD-RW discs, however, can be erased,
refreshed and re-recorded.
• Once you have recorded on a CD-R disc, the data
cannot be erased from it.
Copy-protection
The CD-RW4U allows copy-protection to be applied
to the discs produced. Naturally, the copy-protection
applies only to digital-to-digital copies.

until the display shows COPY

There are three settings:
setting.
• FREE(may be freely copied), where no copy-
protection is applied to the recorded disc.
• 1GEN(single-generation copying—SCMS),
where one digital copy (“child”) can be made from
the recorded disc, but no digital copies (“grandchil-
dren”) can be made from the child.
NOTE
Copy-protection applies on a ““per-track”, not a per-disc
basis. This means that you can apply different copy-protec-
tion levels to different tracks (but you can’t apply different
copy-protection levels to different parts of the same track).
If copy-protection is important to your work, you may want
to check this setting every time you make a recording, to
ensure that you have the protection level that you want.
• PROH(copy prohibited) which prevents any digi-
tal copies being made from the recorded disc

the source is exceptionally quiet.
NOTE
According to the “Red Book” (the specification for audio

Bear these limitations in mind when recording.
An analog signal input at nominal level, with no cut
or boost from the volume controls (that is, with the

Also remember that when recording from an analog

than the “noise floor” (the base level of hiss, pops
and crackles which may come from an older vinyl
recording, for example). If the “noise floor” is higher

To stop synchronized recording:

Stop the source. After a few seconds, the unit

the stopping of the source and entering
record ready mode is used to record a gap at
the end of the track.

NOTE
When recording in sync mode, you may notice a slight
delay between starting the source, and the CD-RW4U
responding. This is due to the way in which the unit works,
storing the data in a memory buffer before writing it to the
disc. The resulting delay is therefore not a cause for con-
cern—all audio data received between the start and end
points will be recorded.

This section deals with the actions taken after record-
ing: finalizing for CD-R and CD-RW discs, and erase
operations for CD-RW discs.
can be “unfinalized” using the CD-RW4U, i.e. their
TOC can be deleted, and if there is space, further
material can be recorded on them. Even if the disc is
full, tracks can be erased following the unfinalize
process, and new material can be recorded.
Once finalized, CD-R discs are truly final—no more
can be recorded on them. By contrast, CD-RW discs
Finalizing discs
page 12), in order for a disc to become a standard
CD, it must have a Table of Contents (TOC) written
to it. This process is known as finalizing.
3
If finalization has been chosen, the display
changes. The NO TOC indicator goes out, and
the word TOCand the REC indicator flashes
in the display. The unit starts counting down
from a time shown on the display (about 1
minute 10 seconds).
An unfinalized disc can always be distinguished on
the CD-RW4U by the NO TOC indicator under the disc
type on the display being lit when the disc is inserted.
After finalization, a CD-RW NO TOC changes to
CD-RW and a CD-R NO TOC changes to a CD.
To finalize a disc:
If the PLAY/PAUSE key is pressed while the finaliza-
tion process is taking place, playback starts as soon
as the finalization process ends. If the OPEN/CLOSE
key is pressed while the finalization process is taking
place, the tray opens as soon as the finalization pro-
cess ends. Pressing any other key during the finaliza-
tion process has no effect.

loaded, and the unit in stop mode, press the

If you do not want to proceed with the final-
izing process, press any other key (such as
the STOP key).

Although CD-R discs finalized on the CD-RW4U may be
replayed on ordinary CD players, remember that finalized
CD-RW discs may not play on CD players.

5 – After recording—Erasing
Erasing
Unfinalizing (described above) is a special case of
erasing a disc. It is also possible to erase a track or
tracks, starting with the last-recorded track, a whole
disc, or to “refresh” a disc.
NOTE
Erase procedures are possible only on a CD-RW disc.
Even if a CD-RW disc has been finalized, selecting an
erase procedure will automatically unfinalize it prior to era-
sure. The disc may then have to be re-finalized. Remember
that it is not possible to perform any erase procedures on a
CD-R disc.
Erasing tracks
It is possible to erase the last recorded track, the last
two recorded tracks, the last three recorded tracks,
etc. It is not, however, possible to erase tracks in the
“middle” of the disc.
NOTE
If only one track has been recorded on the disc, only the
available.

been selected, press the MULTI DIAL control

If the display does not show ERASE XX-
XX?, where XXis the number of the last
track recorded on the disc, turn the MULTI
until it is displayed.
If the erase operation has been selected, the
word ERASEflashes on the display, and
the timer starts counting down. The process
will typically take around 20 seconds).
3
Turn the MULTI DIAL control or use the SKIP
keys to change the number of the first track
to be erased. The highest value that this num-
ber can take is the last track recorded (e.g. if
17 tracks have been recorded on the disc,
17-17means that the last track only, 17,
will be erased). The lowest value that this
number can take is 2(if this number was 1,
the whole disc would be erased, as described
below).
At the end of the countdown period, the word
Completeappears briefly on the dis-
play, and the display returns to the track/
time display.
If the PLAY/PAUSE key is pressed while the erase
process is taking place, playback starts as soon as the
erase process ends. If the OPEN/CLOSE key is
pressed while the erase process is taking place, the
tray opens as soon as the erase process ends. Pressing
any other key during the erase process has no effect.
If you do not want to proceed with the erase
operation, press any other key (such as the
STOP key).
Erasing a whole disc

on a disc), follow the procedure below:

If a CD-RW disc has been corrupted at any point (e.g.
power has been cut off in the middle of a finalize
operation, etc.), or has been used in a computer or
another piece of equipment that makes it unreadable,
it is possible to “refresh” the disc to make it usable
again. This is equivalent to formatting a disk on a
computer to prepare it for use. This operation
destroys all data on the disc.
