The Channel Plus 5445 Video Modulator converts four video and stereo audio inputs into four programmable TV channels (stereo audio is converted to monaural audio after modulation). The 4-channel modulator offers video loop-through for the use of the MPT2743 cable set, and jumpers located on the back 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 computer monitor or VCR. This channel modulator has a full 25 dB output for effective use and frequency-agile tuning. The digital tuning range includes UHF channels 14-64 and CATV channels 65-125. Get a variety of options with your entertainment through the television with this video modulator.
