Kramer 712N Composite Video & Stereo Audio over Twisted Pair Receiver
|
The 712N is a twisted pair receiver for composite video and unbalanced stereo audio signals. The 711N transmitter converts composite video and stereo audio to a twisted pair signal and the 712N receiver converts the twisted pair signal back into composite video and stereo audio signals.
- Bandwidth - 85MHz (- 3dB).
- Twisted Pair Input/Outputs - RJ-45 Connectors
- Looping Input - 712N (RJ-45)
- Selectable Input Signal Termination - 712N.
