Execution of recording
Carry out various recordings while the D-160 is chase locked to the sequence
software.
<Note>
When you select “Vari” for the Slave mode setting, the D-160 will use the Vari-pitch
function to lock to the MTC coming from the master device.
However, if you select an S/P DIF digital signal or an adat digital signal for the digital
input track in Setup mode, the D-160 will sync with the word clock via the input
signal.
Therefore, when you set up a digital input track, the D-160 will not sync with the MTC
even if “Vari” has been selected for the Slave mode setting. Once the D-160 locks to
the master device, it will sync to the external digital input signal (in the same manner
as when SP DIF or adat signals are used).
<One Point Advice>
Sync signal "Free" of the "Slave mode setting" menu:
When the D-160 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 D-160, it will not be able to follow the speed difference (MTC speed difference
of the master) of the D-160 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 D-160 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 unit and slave unit exceeds 10
frames, the D-160 will assume that chase lock has been disengaged and the slave unit
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 unit will continue to run while
admitting this drift.
