  • Specifications
  • SB-3770 is a high speed Video Bandwidth small signal 700MHz, large signal 380MHz Distribution Amplifier product. It’s one of the most innovative Component Video(YPbPr), Digital Audio(PCM) and Stereo Audio(AR/AL) with Loop output function Distribution Amplifier product on the market today. Support wall Rack mount type. It has 1 individual input with 7 individual outputs. Because it is a Component Video/Digital and Stereo Audio Amplifier, the input may be distribution to any output ; it completely eliminates the need to constantly move around Component Video, Digital Audio and Stereo Audio input and output cables. This Distribution Amplifier is ideally suited for TV for resolution 480p, 720p.
