Advanced recording
The signal level which may be used with synchronized
recording operations (here called the “trigger level” or
“threshold”) is set as below:
1 With a recordable disc loaded, press the
1 With a recordable disc loaded, press the
MENU
key
until the display shows:
S_LVL>-XXdB
, where
-XX
is the current value.
2 Turn the
MULTI DIAL
control or use the
SKIP
keys
to change the value between -24, -30, -36, -42, -48,
-54, -60, -66, and -72 dB (-60, -66 and -72 are only
for digital signal).
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 signal will trigger the
start of recording.
When a digital source is selected, there is another option,
When a digital source is selected, there is another option,
DD, which means that any digital signal above the zero
level will trigger the recording.
Setting the trigger level
An input signal used as trigger to start recording is the
sound level rises above the threshold for one second or
more:
S_LVL
Start of recording
level
time
Noise level
Synchronized recording stops when the sound level drops
below the threshold for five seconds:
S_LVL
REC standby
level
time
Five seconds
If you set the threshold value so that only high-level signals
trigger recording, remember that this will not record the
start of a piece which has a slow fade-in:
S_LVL
Recording starts
level
time
This part of the
track may not be
recorded
If the “noise floor” is higher than the threshold, synchro-
nized recording will not take place.

NOTE
Remember that when recording from an analog
source, the threshold should set so that it is higher
than the “noise floor” such as the base level of hiss,
pops and crackles which may come from an older
vinyl recording, for example. However, synchronized
recording is not recommended with the PHONO mode
(see “Recording to disc from the RIAA PHONO inputs”
on page 23).

If you want to prevent the “five seconds” at the end of
recording, try restricting the number of tracks using DD
mode (see “Restricting the number of tracks” on page 23
and also “Automatic track division” on page 26). This will
stop recording immediately so the “five seconds” will not
be recorded. When there are no tracks left to be detected in
DD mode, you need to make an extra track on the source
media before recording.
