The AVS473 Audio Video Switch is an automatic 2X1 Stereo audio follow video switching system that is controlled by an external contact closure or an external TTL signal. This device is a Broadcast quality Audio and Video Relay switch that will handle NTSC, PAL and HD-TVI video signals. The unit is in the “A” channel position until a contact closure or TTL signal is applied to the control input, then it switches to the “B” channel position. If a power failure occurs the unit will automatically switch to the “A” channel position.

The unit can be used to engage a hot standby source or to put up a test pattern when main video fails. This system will maintain your video and stereo audio integrity and reduce trouble calls. It can also be used where unattended video switching must occur if used with an AVI473 “Video Loss Indicator”.

Also inculded are front panel LED’s which indicate the status of the video switch. When the Channel A “CH-A” LED is on the unit is switched to the “A” input both audio and video. When the Channel B “CH-B” LED is on the unit is switched to the “B” input with both audio and video.

Standard 75 Ohm “female” BNC connectors are used for the video inputs and output, the un-used video input is terminated when not connected to the output. A screw terminal connector is used for the balanced stereo audio inputs and outputs. The unit will switch Left and Right audio or Mono with the video switch.
