Essential Info

The RU-VDA4 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 jacks. Power connections are made using full-size barrier block terminals on the rear panel.

The RU-VDA4 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 ohm 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.

This item requires a 24V power supply such as the PS-24K for operation.
