This Model One-Channel Video Modulator has the same output power as the rest of the 5400 series, but it is a quarter of the size. Video and stereo audio inputs are modulated to a programmable TV channel (stereo audio is converted to monaural audio after modulation). This Model modulator offers video loop-through. A jumper on this Model terminates the video input at 75 ohms. When the jumper is removed, the input can be looped using a "Y" adapter to feed the video to a local monitor or VCR. Features: • One modulated TV channel • Channel range: CATV 65-125 (excluding 95-99) and UHF 14-64 • Pushbutton digital programming of modulated channel • Compatible with DA-8200 and DA-550 series distribution amplifiers • 4.6" W x 1.0" H x 3.2" D
