Provo CP5425 - Channel Plus Two Channel Video Modulator

The Model 5425 Two-channel Video Modulator converts two video and stereo audio inputs to two programmable TV channels (stereo audio is converted to monaural audio after modulation). The Model 5425 modulator offers video loop-through. Jumpers on the Model 5425 terminate the video inputs at 75 ohms. When a jumper is removed, the input can be looped using a "Y" adapter to feed the video to a local monitor or VCR.
