4 – Recording—Basic recording
22 TASCAM CD-RW4U
Basic recording
NOTE
According to the “Red Book” (the specification for audio 
CDs), a track cannot be less than four seconds in length, 
and there can be a maximum of 99 tracks on an audio CD. 
Bear these limitations in mind when recording. 
If you press either the 
STOP
 or the 
PLAY/PAUSE
 or 
PAUSE
 key within four seconds of starting recording, the 
unit will continue recording until four seconds have elapsed 
(since the start of recording) and then stop or pause as 
appropriate.
After selecting the input source (“Input selection” on 
page 19), it is possible to start recording.
The basic record procedure is as follows:
1Load a recordable disc is into the unit. As the 
disc is loaded, the display shows TOC 
Reading.
When the disc has been loaded, the display 
indicators show 
CD-R
, 
NO TOC
, or 
CD-RW
, 
NO 
TOC
, as appropriate.
2Press the RECORD key (5 or E). The unit 
enters record ready mode, as shown by the 
REC
 and pause indicators on the display. As 
the unit enters record ready mode, the dis-
play shows Now OPC (Optimum Power 
Control), as the unit prepares to record on 
the disc.
If the digital source has been selected (see 
“Input selection” on page 19) and is not con-
nected properly, or is not powered up, the 
message D-IN UNLOCK! (digital 
input is unlocked) will be displayed to show 
that the system is not ready to record.
3Adjust the level of the source (“Level adjust-
ment” on page 20).
NOTE
The red 
OVER
 indicators on the meters should never light. 
Unlike analog equipment, digital audio units produce 
extremely unpleasant sounds when distorted, and there is 
no “headroom” after the 
0
 mark. If recording digitally from a 
commercially-produced CD, the volume set in the menu 
should be 
0dB
. This will maintain all the dynamic range 
of the source CD without clipping. Only boost the signal if 
the source is exceptionally quiet.
An analog signal input at nominal level, with no cut 
or boost from the volume controls (that is, with the 
INPUT control between the “1 o’clock” and “2 
o’clock” positions, is equivalent to a reading of 
between –20dB and –12dB on the meters (in other 
words, 0 is equivalent to 16 dBFS).
4Press the PLAY/PAUSE 6 or PLAY key L to 
start recording. 
Note that there is no need to “cue up” the 
recording position—the unit always finds the 
next available location on the disc and start 
recording to it.
5Press the PLAY/PAUSE 6 or PAUSE key K 
to pause recording temporarily. The pause 
indicator on the display shows this. Pressing 
PLAY again restarts recording with a new 
track number.
Alternatively, press STOP (7 or J) to stop 
recording. When recording stops, the display 
shows PMA Writing (Program Mem-
ory Area) and the 
REC
 indicator flashes for a 
few seconds as the unit writes to the disc. 
NOTE
While the “PMA Writing” message is displayed, all keys are 
disabled, and the unit is actually writing to disc. Do not dis-
connect the power or subject the unit to severe vibration or 
shocks at this time, as this will prevent proper recording of 
the information.
When this message disappears, you must 
press the RECORD key (step 2) before 
restarting the recording. Recording restarts 
with a new track number.
NOTE
Remember that every time recording is paused or stopped, 
when recording is restarted, a new track will always be 
started. It is not possible to record in two “stages” within 
one track.
Playing back tracks
Although an unfinalized disc cannot be played back 
on an ordinary CD player, the CD-RW4U can play 
back tracks that have been recorded.
Use the MULTI DIAL control B or the  SKIP keys I 
to select a track for playback.
