Audio Follow Video and Breakaway Audio Configurations
Video and Audio signals are switched by separate crosspoint modules. All crosspoint modules
can be switched at the same time. Audio and video can be switched separately (breakaway) if
desired.
Connecting Peripherals
Control panels, sync inputs, and power are all connected to the rear of the frame. The peripherals
area may vary depending on the model size and type.
Sync Connector
There are two BNC connectors labeled "REF IN". This is a "looping" input for sync referencing.
Connect either composite sync, video with sync, or Tri-level sync to either BNC. If desired, use
the second BNC to loop the signal to another device. If the loop is not used, terminate the second
BNC with 75 ohms.
If a video sync signal is applied to the routing switcher, the control system will cause all switching
to occur during the vertical interval of the reference. If no sync is available, the routing switcher
will switch at a random point rather than during the vertical interval of the reference signal.
AC Power Connections
Some SVS routing switchers offer redundant power supplies but must be specified prior to order.
The power supplies are universal AC inputs. Voltage selection is not necessary because the
power supply senses the correct AC input automatically.
The optional redundant power supply is an external AC to DC converter.
