MASTER
Use the buttons to select the master clock to use.
INT button (default):
Use this unit’s internal clock.
WORD button:
Synchronize with the word clock input through the
WORD/VIDEO IN connector.
VIDEO button:
Synchronize with the video clock input through the
WORD/VIDEO IN connector.
DIN–1, DIN–2 buttons:
Synchronize with the clock of the digital signal selected as
the input of DIGITAL IN 1/2.
You cannot select an input as the master clock if the
sampling rate converter is ON for that input.
NOTE
・ A mark appears on the button of the currently active master clock.
・ If synchronization from an external clock is interrupted, the unit’s
internal clock becomes active. In this case, the
mark appears on
the INT button to show that it has become the active clock, and the
mark appears on the button of the selected external clock that was lost.
SYNC page
Make settings related to synchronization on this page.
STATUS
Shows the status of the currently loaded project’s sampling
frequency and clock synchronization.
Play Fs
When playing a take with a sampling frequency of 48 kHz, 48 kHz
pull-up or 48 kHz pull-down, the unit can be made to
synchronize with an external clock by setting it to play back with
pull-up or pull-down.
Depending on the combination of Project sampling frequency
and Play Fs settings, the unit will operate with the sampling
frequency shown below (default:
OFF).
NOTE
Set this to OFF before recording.
Recording is not possible when set to
Pull-up +0.1% or Pull-down
–0.1%
. If you try to record when not OFF, “Cannot REC” appears in a
warning pop-up window.
TC Chase
Use to turn playback synchronized with timecode ON or OFF
(default).
Set it to
ON when you want to match the timing of this unit’s
audio with a timecode master device (audio recorder, video or
built-in time code generator).
You can also set timecode offset (TC Offset) with the timecode
master device. Touch the
EDIT button to open the CHASE
Offset
screen where you can set the offset value in a range
between −23:59:59.29 and +23:59:59.29 (default: 00:00:00.00).
NOTE
TC Chase can also be turned ON and OFF by pressing the SHIFT and CALL
keys at the same time.
TC Rechase
Turn this function, which re-synchronizes when synchronization
with timecode becomes inaccurate,
ON or OFF (default).
When set to
OFF, after synchronizing once, input time code is
ignored and the unit operates in free run mode.
When set to
ON, set the amount of inaccuracy that triggers
rechasing.
To set the amount of inaccuracy that triggers rechase, touch the
knob and turn the DATA dial to select a value in frames of
1/3, 1,
2 (default), 5 or 10.
Master TC
Set whether the unit synchronizes with the built-in timecode
generator or with timecode input from another device.
Internal button:
Synchronize with the built-in generator.
External button (default):
Synchronize with timecode input from another device.
