Sync signal “Vari” of the “Slave mode setting” menu:
When the VF160 is made to chase lock by MTC only,
variable pitch will be constantly applied by external
MTC. If a digital signal is output to an external digital
equipment from the VF160, it will not be able to follow
the speed difference (MTC speed difference of the
master) of the VF160 and the external digital equipment,
in some cases, may not be able to input a continuous
digital signal.
As a counter measure, the sync signal should be set to
“
Free
” by the “
Slave mode setting
” menu. Using this setting,
the VF160 will enter self operation by the internal clock,
after completion of chase lock, and it will be possible to
supply a stable digital signal to the external equipment.
Under this setting, when MTC drift between the master
recorder and slave recorder exceeds 10 frames, the
VF160 will assume that chase lock has been disengaged
and the slave recorder will carry out position matching
again with the master unit (re-chase operation). During
the re-chase operation, sound output will be muted and
the digital signal will also be interrupted. If it is within
10 frames, the slave recorder will continue to run while
admitting this drift.
Confirming chase lock
1. When the sequence software is played, “CHASE” and “MTC”
in the display will be light and the chase lock will be completed.
Check that the MTC output by the sequence software and
MTC time displayed in the VF160 are the same.
2. When the sequence software stops, MTC will be interrupted
and the VF160 will also stop.
“
CHASE
” in the display will change from lit to blinking.
3. During FF/REW of the sequence software, the VF160 will
remain stopped but upon starting to record, the VF160 will
immediately chase lock.
Should it not be possible to chase lock, re-check connections
/ cables and all settings.
<Note>
Chase lock of the VF160 by MTC only is permissible when
speed difference of the MTC from the master is within
+/- 5.6%. Against the MTC within this range, variable
pitch will be constantly applied internally for chasing.
Chase lock, however, will not function against MTC at a
speed difference outside this range. Also, when the
master speed difference is large, it is advised to let the
VF160 learn the master speed by entering PLAY prior to
recording. By doing so, it will be lock faster from the
second and later sessions.
Execution of recording
1. Carry out various recordings while the recorder is chase locked
to the sequence software.
<Note>
Normally, when “Setup of slave type” is set to “
Vari
”, the
VF160 will be constantly controlled by vari-pitch and
follow the MTC, which is the master.
However, if the digital input is set to “
SPDIF
” or “
adat
”
via the SETUP mode “Setup of digital input,” it will be in
“Word clock external sync operation” by the digital
signal (S/P DIF or adat) that is input.
Therefore, it must be noted that when “Setup of digital
input” is executed, even though “Setup of slave type” is
set to “
Vari
”, it will not follow by application of vari-pitch
and upon completion of lock, it will change to external
sync operation by the digital input signal.
