Differential Video Driver MSM2915-01-x Product Description The MSM2915-01-x is designed to reduce noise in video signals. The unit amplifies the video signal output of source equipment to allow video transmission over twisted/shielded pair wiring. Its outputs are utilized in conjunction with Audio International’s MSM2917-0x-x Video Receiver or A/V-4595-xx-x Audio/Video Controller. The increased signal voltage out of the unit reduces signal-to-noise ratio, resulting in clearer video. The MSM2915-01-x has four video source equipment inputs and eight video channel outputs (two outputs per input channel). Low impedance / high level video drivers provide the increased signal level needed to overcome noise interference. Four DIP switches are provided for each output to select the number of loads connected to that output (maximum 5 loads per channel). The unit has passive coaxial video outputs for each input to pass the signals to other devices. The “-x” in the model number denotes the type of connectors utilized on the unit.
