Sync X Setup & External Offsets Section
With Sync X selected as the Clock Master, the Sync X Setup & External Offsets section lets you configure the Clock Reference,
Video Reference, and Positional Reference settings for Sync X.
Clock Ref (Sample Rate Lock)
Select the Clock Reference Source for Sample Rate Lock, both for Pro Tools and any connected external devices. Depending on
the selected source, Sync X will either generate clock signal (such as if
Internal is selected), or it will lock to the incoming clock
signal from the selected external device (such as if
Word Clock is selected).
Source
Select the appropriate Clock Reference Source for Sample Rate Lock from the following options:
Internal Uses the Sync X internal clock and generates clock signal at the session sample rate (or the session sample rate as modified
by any specified Pull Up or Pull Down setting).
Video Reference Locks to the incoming Video Reference Input signal.
LTC Locks to the incoming LTC signal.
Bi-Phase Locks to the incoming Bi-Phase signal.
Pilot Tone Locks to the incoming Pilot signal (NTSC 60 Hz or PAL 50 Hz).
AES3 Locks to the incoming AES3 signal (DB-25).
AES3id Locks to the incoming AES3id signal (BNC).
10 MHz Locks to the incoming 10 MHz signal (BNC).
Word Clock Locks to the incoming Word Clock signal (BNC).
Loop Sync Locks to the incoming Loop Sync signal (BNC).
Output Sample Rate
This displays the precise sample rate distributed to all clock outputs. When the Clock Reference Source is set to Internal, the Out-
put Sample Rate
can be the session sample rate, the session sample rate modified by VSO (Internal clock), or by Pull Up/Down.
If Sync X is following an external
Clock Reference Source, the Output Sample Rate is proportional to any discrepancy between
the session sample rate and the incoming reference. External devices following Sync X receive and clock to this sample rate.
Clock Ref Status Indicator
The Status indicator shows the state of the selected clock reference. Text to the right of the Status light indicates if Sync X is
Generating clock reference, or if it is Locked or Not Locked to the selected Clock Source. The Clock Ref Status indicator is mir-
rored on the front panel of Sync X as well as in Synchronization view in the Transport window and in the Edit Window toolbar.
* expected rate = session sample rate +/– any pull up/down factor
