The STE “MS” Series features high performance audio/video routing switchers. Each unit, housed in rackmount chassis, accepts and routes almost 1 Volt p.p PAL or NTSC video input, Composite, Y/C (S-VHS) or RGB. Mono or Stereo unbalanced audio up to 4 volt p.p or balanced audio from 0 to +4dbm. All switching is accomplished during the vertical interval. Video and Audio inputs can be routed simultaneously or independently: they do not need to have the same destination.
