The SB-5544LCM is a true matrix routing switcher for AV (Composite & Stereo Audio) signals with full support of NTSC or PAL Composite Video & Stereo Audio systems. It has (4) individual Composite Video and Stereo Audio inputs with (4) 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-5544LCM 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 inputs can be made via the front panel push buttons or an infrared remote control or RS-232 control by computer.
