with Mono Audio Transceiver
S-Video + Composite Video + Mono Audio Transceiver #500034.
This Transceiver Balun allows you to send S-Video, Composite Video and a Mono Audio over a single Category 5 (or higher) Cable. You can use it to send the signals either way. For instance, you can use the S-Video to receive a signal from a camera into your recorder or mixer and you can use the composite video to feed a separate monitor (from a separate source) and the audio to talk to your cameraman.
