The VIDEO OUT section on 3Play’s backplate provides vertical columns of four BNC connectors. These represent:
- Channel A (labeled 1 in the VIDEO OUT group)
- Channel B (labeled 2 in the VIDEO OUT group)
- 3Play 4800 only – Aux (labeled 3 in the VIDEO OUT group); carries the same signal as either Channel A or Channel B, depending on 3Play’s current Channel Delegate.
