INTRODUCTION
Congratulations on your purchase of one of the most innovative
8x8 AV (Composite Video/Audio) matrix switching products on the
market today. 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

infrared remote control or with RS-232 control by a computer.
