  • Model: SB-5548BNC
    UPC: 4718091554819

The SB-5548BNC is a true matrix routing switcher for AV (Composite & Stereo Audio) signals. Full support for NTSC or PAL Composite Video & Stereo Audio TV systems. The SB-5548BNC has (8) individual Composite Video (BNC connector) and Stereo Audio inputs with (8) individual Composite Video (BNC connector) and Stereo Audio outputs. Audio outputs control and adjust volume and AR/AL balance. 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 switcher 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 with a computer. A RS-232 Windows GUI interface is provided for matrix routing control (Windows only).
