							6  TASCAM CD-D1x4 
1 – Introduction
The TASCAM CD-D1x4 CD duplicator provides 
you with a quick and simple method of copying your 
original audio material in CD format on up to four 
drives at once at considerably more than real-time 
speeds (up to 16 times), using easily-obtainable, low-
cost CD-R or CD-RW media, with no auxiliary 
equipment or computer system required. 
Another CD-D1x4 may be slaved to the first in order 
to provide an eight-drive unit (see “Cascading” on 
page 19).
It is especially useful for duplicating material pro-
duced using TASCAM CD-RW recorders on CD-RW 
media, which may be unplayable on certain types of 
CD player. The CD-D1x4 can read CD-RW discs 
produced on CD-RW recorders for easy duplication.
Copying can be performed on a disc-at-once basis 
(DAO) when the CD-D1x4 copies or performs track 
extraction operations on an audio disc, and on a 
track-at-once (TAO) basis for other discs.
The CD-D1x4 should only be used to duplicate CD-
ROM material to which you own copyright or for 
which you have appropriate permission.
NOTE
This product is designed to help you record and repro-
duce sound works to which you own the copyright, or 
where you have obtained permission from the copy-
right owner or the rightful licensor. Unless you own the 
copyright, or have obtained the appropriate permission 
from the copyright owner or the rightful licensor, your 
unauthorized recording, reproduction or distribution 
thereof, may result in severe civil and criminal penalties 
under copyright laws and international copyright trea-
ties. If you are uncertain about your rights, contact your 
legal advisor. Under no circumstances will TEAC Corpo-
ration be responsible for the consequences of any ille-
gal copying performed using the CD-D1x4.
Depending on the quality of the source CD (audio 
CD, CD-R, CD-RW or CD-ROM), it is possible to 
copy material at up to sixteen times the real-time rate 
(selectable from the front panel), making it conve-
nient for rapid duplication of a number of identical 
discs, etc.
Depending on the content of the source CD, you may 
not be able to read it, or to make a completely accu-
rate copy of the source. Making copies of copies of the same disc may 
degrade the sound quality. Always try to duplicate 
from an original disc, whenever possible.
NOTE
Although the operation of the CD-D1x4 is relatively 
straightforward, we strongly suggest that you read this 
manual before starting operations. There are a few fac-
tors affecting the production of CD-R discs using the 
CD-D1x4 which may not be immediately obvious.

							1 – Introduction
  TASCAM CD-D1x4 7
About CD-R and CD-RW discs
The CD-D1x4 uses CD-R and CD-RW media, and 
can also use CD-R and CD-RW Digital Audio media. 
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.
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 may be recorded. The pack-
aging of CD-R discs will include one of the follow-
ing logos:
By contrast, a CD-RW disc can be used in much the 
same way as a CD-R disc, but the disc can be erased, 
and the disc can then be re- used for other recordings. The packaging of CD-RW discs will include one of 
the following logos:
High-speed RW discs may be recorded at a higher 
speed than the usual high-speed discs. These will be 
marked on the packaging with a special logo:
However, you should note that an audio CD created 
using a CD-RW disc may not play back satisfactorily 
on every audio CD player. This is in no way a limita-
tion of the CD-D1x4 itself, but of the difference 
between the different types of media and the methods 
used to read them.
CD-R discs created on the CD-D1x4, by contrast, 
may be played satisfactorily on the majority of audio 
CD players.
Recordable media
When a CD-R disc has been written, no more data 
can be written to it, and it is fixed, but when a CD-
RW disc has been written, it can be erased and 
reused.
Note that the CD-D1x4 may not be able to use CD-
RW media that have been erased by other models of CD recorder. We recommend that you erase such 
media in the CD-D1x4 before use. Also note that you 
may have to wait some time after loading before such 
media are recognized by the CD-D1x4 (the drive 
indicator goes out).
Installing the CD-D1x4
The CD-D1x4 is designed to fit into 4U of standard 
19” rack space. We suggest that you leave 1U of 
space above the unit to allow for cooling.There are no connections to be made to and from the 
CD-D1x4 other than the power connection on the 
rear panel, as the unit is completely self-contained.
However, you can use the supplied cable to link two 
CD-D1x4 units together, and set one as the master 
unit, and one as the slave. This setting is made using 
the rear panel switch.
Leave 1U of space above each unit in a rack to allow 
for cooling.
Temperature considerations The ambient 
operating temperature should be between 5°C and 
35°C (41°F and 95°F).

Front panel
1STANDBY/ON switch Press this switch 
once to power on the unit, and again to turn it to 
standby mode. There is also a power switch on the 
rear panel which must be switched on first. 
NOTE
If the unit does not turn on when you turn the front 
panel switch on, make sure the switch at the rear of the 
unit is also turned on.
2Display The 2 x 16 LCD display displays the 
menus and sub-menus available, and also provides 
information on the status of the current operation, as 
well as displaying error messages, etc.
3ESCAPE key The ESCAPE key is used to 
go “up” a menu level or to cancel operations. A dou-
ble “beep” is often produced when the 
ESCAPE key 
is pressed.
4MODE key The MODE key is used to cycle 
through the different menus and options available to 
put the unit into the different modes, as explained 
below.
5ENTER key The ENTER key is used to con-
firm the selection of menu items and options. It also 
acts as a “start” key to start operations.
6MASTER drive The MASTER drive is used 
to hold the source CD. This may be a pre-recorded 
audio CD or CD-ROM which you have permission to 
copy, a CD-R or a CD-RW disc.The eject button is used to eject the master disc when 
no operation is in progress. The indicator on this 
drive shows when the disc is being accessed.
In the “Play audio” mode (see “Audio playback” on 
page 17), a pre-recorded CD may be inserted into 
this drive, and played back, track by track. The head-
phone jack and volume controls of this drive are 
operational in this mode only.
7Slave drives (1, 2, 3, 4) The slave drives 
hold the target discs. 
The eject buttons are used to eject the target disc 
when no operation is in progress. The right indicator 
on these drives shows when the disc is being 
accessed for reading and the left indicator shows 
when the disc is being accessed for writing.
In the “Play audio” mode (see “Audio playback” on 
page 17), an audio CD may be inserted into one of 
these drives, and played back. The headphone jack 
and volume controls of this drive are operational in 
this mode only. We suggest that to avoid tangling the 
cord of the headphones in the drive door when it 
opens (automatically in many cases), you only plug 
in headphones when using the audio playback mode.
NOTE
If a disc is in a drive and cannot be removed by using 
the eject button, you can insert a thin stiff wire (such as 
the end of a paperclip) into the hole on the front panel 
of the drive (under the tray) when the unit is turned off. 
This will open the tray.

3 – Care of recordable media
The Compact Disc medium is a robust medium, and 
the discs can survive a good deal of physical abuse. 
However, there are precautions that you should take 
when handling CD-R discs which are different to 
those 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, and 
fingerprints, grease, etc. can cause errors in the 
recording process.
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-generating 
electrical devices.
Always store CD-R discs in their “jewel cases” to 
avoid dirt and dust accumulating on their surfaces.
Do not put labels or protective sheets on the discs and 
do not use any protective coating spray.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.
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.
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.
It is important that you do not use CD lens cleaners 
(including CD-R or CD-ROM lens cleaners) with the 
CD-D1x4. The reason for this is that the drives in this 
unit rotate at a much higher speed than those of an 
audio CD unit, and accordingly, the pickup lenses of 
the drives may be damaged by an ordinary CD lens 
cleaner.
Discs recommended for use with the CD-D1x4
For optimum performance, we recommend the use of 
TEAC brand CD-R and CD-RW media.
Since the CD-D1x4 is capable of recording CD-R 
media at up to 16x speed, and high speed CD-RW 
media at up to 10x speed, make sure that media used 
with the CD-D1x4 can be written at these speeds.Only use high speed CD-RW media (as marked on 
the packaging—an example of the logo is given in 
“About CD-R and CD-RW discs” on page 6) for 
high-speed operations on rewritable discs.
You may obtain an updated list of recommended 
media (CD-R and CD-RW discs) at the TASCAM 
Web site (www.tascam.com).
