2.5.4 Synchronization

The detection of the reference standard is automatic. An AES3 digital audio reference signal
connected at the AES Sub-D has a higher priority than any reference signal connected to the BNC
jack.
In stand-alone mode the REF led, when green, indicates compatibility between the sync signal and
the AES output-sampling rate selected. It will be orange if the AES output signals are not
synchronized to a reference signal.
When used in conjunction with a video processor, the reference source is the video module that
delivers a 27 MHz reference signal (via the ABUS front panel connector). The REF led will be green
to indicate the validity of this 27 MHz, orange when it is not valid but with an external valid reference
signal connected at the rear, and red in other cases.
The relative phase between external sync signal and AES samples is respected for any case except
for mode video NTSC. For video PAL mode, output samples are aligned with the start of the first line.
The AES 110 Ω Sync input is located on "AES" Sub-D socket. The switch
A-110 rear panel
"LD110" must be set on the LOZ position to properly terminate the line. Other
syncs are connected on BNC jack "REF.IN". The switch "LD75" must be set on
the LOZ position to properly terminate the line. The second BNC jack is lined to
"REF.IN" input and may be used as loop-through. For this conditional use, the
switch "LD75" must be set on the HIZ position.
AX rear panel The sync signal must be connected on BNC "REF.IN". The switch "LD75" must
be set on the LOZ position to properly terminate the line. The second BNC jack
is lined to "REF.IN" input and may be used as loop-through. For this conditional
use, the switch "LD75" must be set on the HIZ position.
When used in a Symphonie frame, the module 75 Ω ? ? r eference input can be connected to the global
reference signal (video or Word Clock only) instead of the BNC REF.IN. It is done by sliding LK1 to
position 1-2 (GLOBAL) on the rear panel and SW2 to position A75 on the module.
