• Model: SB-5548LCM
    UPC: 4718091554826

The SB-5548LCM is a true matrix routing switcher for AV (Composite & Stereo Audio) signals. Full support of any NTSC or PAL Composite Video & Stereo Audio system. It has (8) individual Composite Video and Stereo Audio inputs with (8) individual Composite Video and Stereo Audio outputs. Because it is a matrix router, any input may be routed to any output; or the same input may be routed to all outputs or any combination. It completely eliminates the need to constantly move around video audio input and output cables. The SB-5548LCM is useful for matrix signals from composite video and stereo audio source devices (such as: VCRs, Camcorders, Video Game Consoles, Video CDs, DVDs, Satellite Receivers, CAT5 Set Top Boxes, etc.) to Composite Video/Audio destination devices (such as: LCD TV, HDTV, Plasma displays, Projectors, etc.). Selection of an inputs can be made via the front panel push buttons or an infrared remote control or with RS-232 control by a computer.
