2.5.2 Output connections

When used with a 75 Ω rear panel, switches SW1, SW2, SW11, SW21, SW12, SW22, SW13,
SW23, SW14, SW24 must be set on the A75 position.
When used with a 110 Ω rear panel, switches SW1, SW2, SW11, SW21, SW12, SW22, SW13,
SW23, SW14, SW24 must be set on the A110 position.
2.5.3 Synchronization
A green Led (REF) on the front-end side of the board indicates when lit that the present external
sync is valid. If the sync signal is an AES or a Wordclock, the user has to select the same
sampling rate (in the FREQ menu) to get a valid sync. When the external sync mode is selected
and non-valid external reference signal is detected, this Led blinks. In external mode, the Led
stays off.
The relative phase between sync 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 setting of internal or external synchronization is made via the user's front interface or
remotely.
110 Ω Ω rear panel The AES 110 Ω sync input is located on "AES" D -Sub socket. The switch
"LD110" must be set on the 110Ω position to properly terminate the line.
Other syncs are available on BNC jack "REF.IN". The switch "LD75"
must be set on the 75 Ω position to properly terminate the line. The
second BNC jack "N/C" 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.
75 Ω Ω rear panel
All sync signal are available on BNC "REF.IN". The switch "LD75" must
be set on the 75 Ω position to properly terminate the line.
ASD- - 711i/712i ASD 711i/712i
When one source equipment is connected to
one ASD-711i or ASD-712i, 600 Ω termination
load can be selected: the corresponding jumper
IN1L, IN1R, IN2L, IN2R must be set on "ON"
position.
When source equipment are connected to
several ASD-711i or ASD-712i, if a 600
Ω termination load is needed, it must be
selected on the last A SD-711i or ASD-712i. The
corresponding jumper IN1L, IN1R, IN2L, IN2R
must be set on "ON" position.
ASD-711i corresponds to only channel 1; ASD-
712i corresponds to channel 1 and 2.
