  • SB-3790 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 mount type. It has 1 individual input with 8 individual and 1 Loop Output 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 full High Definition LCD HDTV Television for resolution 480p, 720p 1080i and 1080p or Plasma display monitor applications. Control is provided power switch via Front pushbuttons with LED readout. SB-3780 without Audio
