5 – Recording—Synchronized recording
34 TASCAM CD-RW402 Owner’s Manual
The conditions under which synchronized recording
stops are:
• the sound level drops below the threshold level for
the time set by the Sync End Time function (“Add-
ing extra time at the end of a recording” on
page 35):
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 with a slow fade-in:
Also remember that when recording from an analog
source, the threshold should be set so that it is higher
than the “noise floor” (the base level of hiss, pops
and crackles which may come from an older vinyl
recording, for example). If the “noise floor” is higher
than the threshold, synchronized recording will not
take place:
Because synchronized recording can be turned on
and off while recording is taking place, it is therefore
possible to record with a synchronized automatic
start, and a manual end, or vice versa.
When the source material is being played back
before synchronized recording is enabled, the condi-
tions under which synchronized recording will start
(after synchronized recording has been enabled) are:
When the signal drops below the threshold for one
second or more and then rises above the threshold
again (this is the general condition, of which starting
synchronized recording from a stopped or paused
source is a special case):
Alternatively, when recording digitally from sources
(MD, CD and DAT) which output track divisions,
synchronized recording starts when a track division
is received, regardless of the level:
To stop synchronized recording:
1 The unit must be in record mode, and the
SYNC
indicator in the display must be lit.
2 Stop the source. After a few seconds, the unit
enters record ready mode. The time between
the stopping of the source and entering
record ready mode is used to record a gap at
the end of the track.
3 If no changes are made to the unit’s controls,
restarting the source restarts recording, as
the unit is still in sync mode and will start
recording again when the source is detected.
NOTE
When recording in sync mode, you may notice a
slight delay between starting the source, and the CD-
RW402 responding. This is due to the way in which
the unit works, storing the data in a memory buffer
before writing it to the disc. The resulting delay is
therefore not a cause for concern—all audio data
received between the start and end points will be
recorded.
