The SB-8804LCM is a true matrix routing switcher for digital audio and stereo audio with volume control (analog only). Integrated with Control4 offers you full audio zone control. The SB-8804LCM has (8) individual Digital Audio and Stereo Audio inputs with (8) individual Digital Audio 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 audio input and output cables. The digital audio connections also support composite video. The SB-8804LCM is useful for matrixing signals from digital audio 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 are made via the front panel push buttons or an infrared remote control unit or PC RS-232.
