The RU-VDA4B is the ideal choice in most applications where video signals need to be distributed. Video inputs and outputs are made on the front panel via BNC, PHONO, or type F jacks. Power connections are made using full-size barrier block terminals on the rear panel.

The RU-VDA4B has two jacks in the input stage. One jack is for the input signal; the other is a loop through output of the source signal.The input stage is bridging. If 75 Ω termination of the input signal is required, the termination is plugged onto the LOOP OUT jack.

Gain is user adjustable from the front panel. The GAIN potentiometer allows adjustment from -1 dB to +7 dB.
