Automatic assemble recording
In automatic assemble recording the CTL signal is
added from where it was broken off.
For example, to dub one channel onto a tape which has
been only partially prestriped, use the RM-3348HR
remote control unit to set that channel only into the
recording ready state, and carry out an automatic
assemble recording.
Since the CTL signal and audio signals can be
recorded in a single pass, this method saves operation
time when compared with insert recording, where the
complete CTL signal is recorded before the digital
audio signals.
Automatic assemble recording
Forced assemble recording
In forced assemble recording, CTL is rewritten from
the recording start point.
The CTL track is written following the sampling
frequency at the recording start point. Therefore, even
if the sampling frequency of the CTL being recorded
changes, there is no need for prestriping. In this case,
however, all digital audio channels must be in the
recording ready state.
