Recording level adjustment (for analog input signals
only)
The peak level meters show the peak level of the analog
input signal held momentarily. The MARGIN indicator
shows how much margin there is between the peak level of
the input audio signal and 0 dB. Whenever a signal having
a higher level than the displayed one is input, the new level
replaces the lower one on the MARGIN indicator.
Turn the REC LEVEL control so that the "OVER" segments
do not light, even at the highest level.
To reset the margin
Press MARGIN RESET on the remote commander. The
margin wil! become "- -".
If the level exceeds 0 dB
The "OVER" segments light in red, and "0.0 dB" flashes.
If "OVER" lights steadily, lower the recording level so that
the peak level meters light between —12 dB (£2 ) and 0 dB
to avoid sound distortion.
Margin
Peak eve! Should not light.
REC LEVEL
If you keep adjusting the recording level with the unit in
the record-pause mode
If the unit is left in the record-pause mode for more than 10
minutes, the record-pause mode will be released
automatically, and the unit will enter the stop mode.
The levels of the input audio signals appear even in the
stop mode, and you can continue to adjust the recording
level. (The "AD-DA" indicator appears on the display.)
In the above case, press the @REC button again to set the
unit to record-pause mode.
If the unit is left in the record-pause mode for more than
10 minutes during digital recording
The record-pause mode will be released automatically, and
the unit will enter the stop mode. (The -"DA" indicator
appears on the display.) In this case, press the @REC to
set the unit to record-pause mode.
If the cable is disconnected or the program source is
intermitted, the digital input signal will be interrupted
during digital recording
The OPTICAL or COAXIAL indicator flashes and the unit will
enter record-pause mode. (For about 10 minutes) ff the
digital signal is input again in this period, the unit will enter
recording mode automatically.
Long play mode

long play mode can be performed as follows.
Analog input signal standard play long play

The digital input signal of 44.1 kHz or 48 kHz cannot be
recorded/played back in the long play mode, even if the
REC MODE selector is set to the LONG position.
