 TASCAM CD-RW750 Owner’s Manual 21
Sync recording (start)
The conditions under which an input signal is used as 
the trigger to start recording in the 
SYNC ALL and 
SYNC 1 modes are:
 when recording digitally from a DAT deck, a digi-
tal track start signal is detected (the signal level is 
ignored):
 when recording digitally from a CD or MD deck, a 
digital track start signal is received, and the signal 
level subsequently rises above the trigger level: when recording from any source other than the 
ones described above (that is, any digital source 
other than DAT, CD or MD, or any analog source), 
recording starts when the input signal level exceeds 
the trigger level.
In this last case, if the signal level is already higher 
than the trigger level, recording starts immediately.
Sync recording (stop)
SYNC ALL In the SYNC ALL mode, recording 
stops when the input level drops below the trigger 
level for more than six seconds.
Also note that in this mode, the auto track function is 
enabled (see “Automatic track division” on page 22).
SYNC OFF Automatic synchronized record start 
and stop functions are disabled and must be per-
formed manually.
SYNC 1 In the SYNC 1 mode, recording stops at 
the start of the next track (when the level of the first 
track has gone below the trigger level for less than 
six seconds and the level of the second track goes 
above the trigger level)
or
When the input level goes below the trigger level for 
more than six seconds (as in the 
SYNC ALL 
mode).

Setting the trigger level
The trigger level is set as below:
1With a recordable disc loaded, press the 
MENU key (9 or 6) until the display shows: 
S_LVL>> -xxdB, where xx is the cur-
rent value.
2Use the MULTI JOG control B or the  SKIP 
keys 
Ito change the value between -24,  
-30, -36, -42, -48, -54, -60, -66, 
and 
-72 dB.
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.
If you set the value so that only high-level signals 
trigger recording, remember that this will not record 
the start of a piece with a slow fade-in:Also remember that when recording from an analog 
source, the threshold should be set so that it is higher 
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 
than the threshold, a false start will occur: 
NOTE
When recording in sync mode, you may notice a slight 
delay between starting the source, and the CD-RW750 
responding. This is due to the way in which the unit 
works, storing the data in a memory buffer before writ-
ing it to the disc. The resulting delay is therefore not a 
cause for concern—all audio data received between the 
start and end points will be recorded.
Automatic track division
The trigger level, as set above (“Setting the trigger 
level” on page 22 can also be used to divide tracks if 
the A-TRACK (auto track) function is enabled.
When this function is enabled, the unit automatically 
inserts a track division in the recorded material when:
 recording digitally from MD, CD or DAT, an incre-
ment signal is detected and the sound level rises 
above the threshold:or
 increment signals are unavailable (e.g. analog 
recording or digital sources other than MD. CD or 
DAT) and the sound level has dropped below the 
threshold for more than two seconds, and sound 
has re-started

 TASCAM CD-RW750 Owner’s Manual 23
To enable or disable automatic track division:
1With a recordable disc inserted, and with the 
unit in record ready mode, press the 
MENU 
key (
9 or 6) repeatedly until 
A_Track>XX is shown, where XX may be 
ON or OFF.
2Tu r n  t h e  MULTI JOG control B or use the  
SKIP
 keys Ito change the value to ON or 
OFF.
The 
A-TRACK indicator at the top right of the 
display lights when the auto track function is 
enabled.
Automatic track division can be turned on or off 
while recording is taking place.
NOTE
When recording certain types of material (e.g. certain 
types of classical music or spoken word) through the analog or non-DAT/CD/MD digital connections, since 
the track divisions are determined by relative silence, it 
is possible that spurious track divisions will be inserted. 
Under these conditions, it may be better to use manual 
track division (see below). 
However, if recording through a DAT/MD/CD digital 
connection, the track number will be incremented only 
when a track division signal is received, followed by a 
rise in volume.
Digital direct
As mentioned earlier, the digital direct mode 
bypasses some of the input circuitry of the CD-
RW750 (the frequency converter and the digital level 
control) to write directly to the disc.
To enable or disable digital direct recording:
1Ensure that the input source is set to DIGITAL 
(either 
COAXIAL or OPTICAL).
2Press the DIGITAL DIRECT key 5 (main unit 
only). The display shows 
D_Direct XX 
where 
XX is ON or OFF.
3Press the DIGITAL DIRECT key to toggle 
between 
ON and OFF.
When digital direct recording is enabled, the 
DIGITAL indicator in the display flashes slowly.
NOTE
As mentioned earlier, the digital direct feature bypasses 
the frequency converter. Recording is therefore only 
possible from sources recorded with 44.1 kHz sampling 
frequency.
Rec mute function
The rec mute function allows instant cut-off of the 
input signal, and records four seconds of silence on 
the disc.
1While recording is in progress, press the REC 
MUTE
 key G.
The display shows 
REC MUTE, the meters 
stop displaying the current level and the moni-
tored sound is cut.
2After about four seconds, the unit enters 
record ready mode.
NOTE
This function is only available from the remote control 
unit. It is not possible to use this function with the main 
unit only.
Fade-in and fade-out
To provide smooth beginnings and endings to 
recorded tracks, the unit provides fade facilities. 
Fade-ins are from –∞ (silence) to the set input level 
(“Input selection” on page 18) and fade-outs go from 
the current input volume to silence.The fade-in and fade-out times can be set indepen-
dently in increments of one second, from 1 second to 
24 seconds.

It is possible to set the fade-in time only (per-
form step 
5 after step 2) or the fade-out time 
only (in step 
1, press the MENU key until the 
fade-out time menu item is shown).To perform a fade-in:
1With a recordable disc loaded, press the 
RECORD key (K or E) so that the unit enters 
record ready mode.
2Start the source material, and press the 
FADER key (M or B). 
The display shows 
Fade IN for the time 
specified in the menu item above.
As the fade progresses, the monitored signal 
gradually becomes louder, reflecting the level 
recorded on disc.
To perform a fade-out:
1While recording, press the FA D E R key (M or 
B).
The display shows 
Fade OUT for the time 
specified in the menu above.
As the fade progresses, the monitored signal 
gradually becomes quieter, reflecting the level 
recorded on disc.
2When the end of the fade-out time is reached, 
the unit goes into record ready mode. Record-
ing can be restarted with the 
FA D E R key or 
the 
PLAY or PA U S E keys.
The fade-in and fade-out times can be reset to new 
values while recording is in progress.
Fades are also possible in digital direct mode (“Digi-
tal direct” on page 23).

5 – After recording
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.
Once finalized, CD-R discs are truly final—no more 
can be recorded on them. By contrast, CD-RW discs can be “unfinalized” using the CD-RW750, 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.
Finalizing
As has been explained earlier (“Finalizing” on 
page 7), 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. 
An unfinalized disc can always be distinguished on 
the CD-RW750 by the 
NO TOC indicator under the 
disc type on the display being lit when the disc is 
inserted.
To finalize a disc:
1With the unfinalized (recordable) disc loaded, 
and the unit in stop mode, press the 
FINALIZE 
key (
F or C).
The display shows 
FINALIZE OK?.
2To start the finalizing process, press the MULTI 
JOG
 control B or press the ENTER key 7.
3If you do not want to proceed with the finaliz-
ing process, press any other key (such as the 
STOP key).
4If finalization has been chosen, the display 
changes. The 
NO TOC indicator goes out, and 
the word 
TOC and the REC indicator flash in 
the display. The unit starts counting down 
from a time shown on the display (depending 
on the disc and material, this value will be 
between 50 seconds and 1 minute 30 seconds).
5After finalization, a CD-RW NO TOC changes to 
CD-RW and a CD-R NO TOC changes to a CD.
NOTE
Although CD-R discs finalized on the CD-RW750 may be 
replayed on ordinary CD players, remember that final-
ized CD-RW discs may not play on CD players.
Unfinalizing CD-RW discs
If a CD-RW disc has been finalized, it is possible to 
erase the Table of Contents in the following way:
1With the finalized disc loaded and the unit in 
stop mode, press the 
ERASE key (G or D).
2If the display does not show the word 
UNFINALIZE?, turn the MULTI JOG con-
trol 
B or use the  SKIP keys I until it is dis-
played.
3To start the unfinalizing process, press the 
MULTI JOG control B or press the ENTER key 
7.
4If you do not want to proceed with the unfinal-
izing process, press any other key (such as the 
STOP key).
5If unfinalization has been chosen, the NO TOC 
indicator starts flashing in the display, and the 
word 
ERASE also starts flashing. The unit 
starts counting down from a time shown on 
the display (depending on the disc and mate-
rial, this value will be between 50 seconds and 
1 minute 30 seconds).
6After unfinalization, a CD-RW indicator 
changes to a 
CD-RW NO TOC indicator.
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 
erasure. 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.
1With the disc loaded, and the unit in stop 
mode, press the 
ERASE key (G or D).
2If the display does not show ERASE XX-
XX?
, where XX is the number of the last 
track recorded on the disc, turn the 
MULTI 
JOG
 control B or use the  SKIP keys I until 
it is displayed.
3Tu r n  t h e  MULTI JOG control or use the  SKIP 
keys to change the number of the first track to 
be erased. The highest value that this number 
can take is the last track recorded (e.g. if 17 
tracks have been recorded on the disc, 
17-
17
 means 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).
NOTE
If only one track has been recorded on the disc, only the 
“erase disc” option (“Erasing a whole disc” on page 26) 
is available.
4When the range of tracks to be erased has 
been selected, press the 
MULTI JOG control or 
press the 
ENTER key 7.
NOTE
This operation cannot be undone. If you are going to 
erase a track or tracks, make sure that they are record-
ings that you really want to erase!
5If you do not want to proceed with the erase 
operation, press any other key (such as the 
STOP key).
6If the erase operation has been selected, the 
word 
ERASE flashes on the display, and the 
timer starts counting down from 
0:20 (20 
seconds).
7At the end of the countdown period, the word 
Complete appears briefly on the display, 
and the display returns to the track/time 
display.
Erasing a whole disc
When you want to erase a whole disc (all the tracks 
on a disc), follow the procedure below:
1With the disc loaded, and the unit in stop 
mode, press the 
ERASE key (G or D).
2Tu r n  t h e  MULTI JOG control B or use the  
SKIP
 keys I until the display shows ERASE 
DISC?
.
3To erase the contents of the disc, press the 
MULTI JOG control or press the ENTER key 
7.
NOTE
This operation cannot be undone. If you are going to 
erase a disc, make sure that it contains only recordings 
that you really want to erase!
4If you do not want to proceed with the erase 
operation, press any other key (such as the 
STOP key).
5If the erase operation has been selected, the 
word 
ERASE flashes on the display, and the 
timer starts counting down a time value shown 
on the display.
6At the end of the countdown period, the word 
Complete appears briefly on the display, 
and the display returns to the track/time 
display.
Refreshing a disc
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.

3To refresh the disc, press the MULTI JOG con-
trol or press the 
ENTER key 7.
NOTE
This operation cannot be undone. If you are going to 
refresh a disc, make sure that it contains only recordings 
that you really want to erase!
4If you do not want to proceed with the refresh 
operation, press any other key (such as the 
STOP key).
5If the erase operation has been selected, the 
word 
ERASE flashes on the display, and the 
timer starts counting down. The refresh oper-
ation typically takes around 40 minutes or so.
6At the end of the countdown period, the word 
Complete appears briefly on the display, 
and the display returns to the track/time 
display (of course, there are no tracks, and the 
disc is as the start, with the total time of the 
disc available for recording).
Titling (CD TEXT)
The CD-RW750 allows you to add titles to discs and/
or tracks on the disc which can be read and displayed 
by suitably-equipped players (naturally, the CD-
RW750 is itself such a player, capable of reading and 
displaying CD TEXT—see “Simple playback opera-
tions” on page 15 and “Time display modes” on 
page 15).
Up to 23 alphanumeric characters (including space) 
may be written in a title. One title may be written per 
disc and per track (for example, it is not possible to 
enter the disc title and artist as separate titles).
NOTE
Titling can only be carried out on an unfinalized record-
able disc, and the titles only become readable by a 
player after the disc has been finalized.
This is a menu option, accessed in the following way 
(this describes the operation from the main unit—
you can also use the 
SKIP keys of the remote control 
unit rather than turning the 
MULTI JOG control, and 
the 
ENTER key of the remote control unit rather than 
pressing the 
MULTI JOG control).
1Press the MENU key until the display shows 
CD TEXT?. Press the MULTI JOG control.
2The display shows T_EDIT DISC?. To 
edit the disc title, press the 
MULTI JOG con-
trol, or to start editing the track titles, turn the 
control so that the display shows 
T_EDIT>01Tr.
Continue turning the control to select the 
track whose title will be edited, and press it when the number of the track whose title will 
be edited is displayed.
3Use the MULTI JOG control both to enter char-
acters (uppercase and lowercase letters, num-
bers, and symbols) and to move the entry 
cursor.
Change between these two cursor modes with 
the 
FADER (JOG MODE) key,
When the MULTI JOG is used for data entry, 
the cursor is a flashing underline (changing 
to data entry mode inserts a space at the 
cursor). Turn the control to select the char-
acter, and push it to confirm the entry and 
move to the next character position.
When the MULTI JOG is used for cursor 
movement, the cursor is a steadily-lit under-
line. 
Use the ERASE/DEL key to delete characters 
at the cursor.
Change between uppercase and lowercase 
letters using the 
DISPLAY key. When upper-
case is selected, 
CAPS is shown in the display.
4Press the FINALIZE/YES key to finish editing 
the title. The display shows 
Writing fol-
lowed by 
Write OK and returns to 
T_EDIT. From this step, you can then select 
another title to edit.
5Press the STOP key when all titles are finished.
6Finalize the disc (see “Finalizing” on page 25).
