4 – Recording—Frequency conversion
20 TASCAM CD-RW4U
Frequency conversion
The sampling frequency for CDs is 44.1 kHz. The 
CD-RW4U will always record (and play back) CDs 
at this frequency. 
However, if recording through a digital connection 
and the source has been recorded at a frequency other 
than 44.1 kHz, or is being played back at a non-stan-
dard speed using a varispeed unit (more than 0.02% 
away from 44.1kHz), the CD-RW4U’s internal fre-
quency converter will automatically convert the 
incoming frequency to 44.1 kHz.
NOTE
If an attempt is made to record from a digitally-connected 
source at a different frequency, the error message 
Not 
Fs44.1k!
is displayed.
Level adjustment
•The analog signals received at the LINE IN jacks 
are controlled with the INPUT LEVEL control C.
•Digital signal levels as well as the level of analog 
signals once they have passed through the INPUT 
LEVEL control are adjusted in the following way:
1Press the RECORD key (5 or E) to place 
the unit in record ready mode.
2Repeatedly press the MENU key (E or 7) 
until the display shows VOLUME 
XXXdB where XXX is the current setting.
3Use the MULTI DIAL control B or the  SKIP 
keys I to adjust the input volume between 
-60dB and +18db (relative to the origi-
nal input level). There is also a ---- set-
ting which represents a complete signal cut.
NOTE
The unit remembers the volume menu settings for both 
analog and digital inputs. These are independent of each 
other, and the volume setting changes to the remembered 
values automatically when the input source is changed.
Time display while recording
While a recordable disc is being played back, the 
four time display modes available in normal play-
back as described in “Time display modes” on 
page 16: 
TOTAL
, 
TOTAL REMAIN
, track 
REMAIN
 and 
elapsed track time.
However, during recording there are fewer options 
available (obviously, the unit cannot see into the 
future and know how much time remains of the track 
which is being currently recorded!).
When in record or record ready mode, repeated 
presses of the DISPLAY key 6 cycle between dis-
playing the remaining time left for recording on the 
disc (
TOTAL REMAIN
) and the elapsed time of the track 
currently being recorded (no indicator lit).
When a recordable disc is stopped, the following two 
options are available: 
TOTAL
 (the total time recorded 
so far on the disc) and 
TOTAL REMAIN
 (the total time 
available on the disc for further recording).
