to change the value between DD ,
-24 , -30 , -36 , -42 , -48 , -54 ,
-60 , -66 , and -72 dB.
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 sig-
nal will trigger the start of recording.
The DD setting is a special case. It is not a signal
level, but refers to the start of a track, as encoded in
the digital input signal. It is therefore only used when
a digital input is received on the
COAXIAL or
OPTICAL digital inputs (but not the AES/EBU
inputs).
NOTE
If the CD-RW2000 is used to record a digital audio
source which is connected using analog connections,
even if the
DD setting above is made, the trigger
level will automatically be set to -54 dB.
Also note these points when making digital recordings from
a CD player or a DAT player when using the
DD setting.
Since the DD setting pays no attention to the sound level,
but only to received subcode, it is possible that when the
CD-RW2000 is in record ready mode and a CD is selected
as the digital recording source, and the source CD is
changed, when the source player reads the TOC of the
source disc, when the first track is read, a spurious signal
will be sent to the CD-RW2000, which will start recording.
Also, when a digitally-connected DAT is used as the
source, and the tape is wound fast (forward or backward) to
cue the source tape to the start of the desired track, you
should remember that START IDs will be sent from the DAT
deck while the fast wind is proceeding. These START IDs
will also trigger recording if the CD-RW2000 is in record
ready mode, and the
DD setting is selected.
For these reasons, we suggest that you only switch on the
DD setting when the source CD player or DAT deck is in
STOP mode.
The conditions under which an input signal is used as
the trigger to start recording are:
• when recording digitally, a digital start signal is
detected, and audio is subsequently detected
or
• the sound level rises above the threshold (see
below) after having been below the threshold for
one second or more. Note that the diagram below
represents a special case (the source is stopped or
paused) of the more general condition, as explained
later:
To start synchronized recording when the source is
stopped or in pause mode:
1 The unit must be in record ready mode, and
the
SYNC indicator in the display must be lit, as
explained above.
2 Start playing the source. The pause indicator
disappears from the display, and the unit starts
recording.
The conditions under which synchronized recording
stops are:
• when recording digitally, an appropriate digital sig-
nal is detected. If the signal is detected from a CD,
the unit enters record ready mode after 2 seconds.
