A switch allows the user to select one output from multiple baseband video or multiple line-level audio inputs. VAC switches include both local and remote control capabilities as standard features by means of an easily accessed DIP switch. This provides local control. Remote control is readily configured via min-DIN “Control In” & “Status Out” connectors. Remote control can be as simple as a toggle switch or as inovative as the customer needs, since VAC switches accept TTL or CMOS level control signals in addition to switch closures.
Additionally, most switches have VAC’s exclusive Power Fail ByPass which use a passive relay to connect Input 1 to the output whenever the switch loses power. This feature acts as a fail safe mechanism ensuring that the highest priority video signal is always available at the switch.
