Advanced Recording Operations
Setting the Recording Mode
You can select between two recording modes, standard
or long, in the following cases.
• When recording an analog input signal with the
INPUT switch set to ANALOG
• When recording a digital input signal with a
sampling frequency of 32 kHz with the INPUT
switch set to DIGITAL
.
REC MODE
Set REC MODE to select the recording mode.
The following table shows the selectable recording
modes and corresponding REC MODE position and
sampling frequency for various input signals.
'Q' The counter in long-play mode
The displayed tape running time, absolute time and
remaining time on the tape are for standard-play mode.
Double the time to obtain the corresponding times for
long-play mode.
Note
Do not change the INPUT or REC MODE setting while
recording. This may cause an error in the "PGM TIME"
display.
Using the SBM (Super Bit
Mapping) Function
The SBM function uses the principles of human
hearing and noise-shaping technology to reduce
quantizing noise within the frequency band.
You can use the SBM function to record on analog
input signal only when the INPUT switch is set to
ANALOG and the REC MODE switch to STANDARD
(either 48kHz or 44.1kHz).

The recording time in long-play mode (the REC MODE
switch set to LONG) is twice as long as standard-play
mode.
Set SBM to ON.
"SBM" appears in the display during recording using
the SBM function.
Note
The SBM function operates only during recording. The
improved sound produced by the SBM function, however,
can be enjoyed during playback, regardless of the SBM
switch position or the DAT deck being used.
