TV/VCR/Cable Switch 75 Ohm

Passive 3-way toslink optical
switch. Passive selection knob
with a spring loaded lock
mechanism and seleciton
indicator. Bi-directional
switching. Size: 5.5"W x
1.3"H x 4.5"D.

Enables 2 audio inputs to be switched to 1 output. Slim metal chassis with black finish. Mounts with velcro, included or double stick tape. 2 L+R inputs, female RCA jacks. Output cable with L+R male RCA plugs, 5ft. long.

4 inputs, 2 outputs. This device switches between 4 S-video/audio sources automatically. When a video signal is detected from 1 of the 4 inputs that channel�s video and audio are switched to the output. To select a different input simply turn on that piece of equipment and the video and audio signals will override the previous signal and route it to the output. Switching is automatic with no user interaction. This unit can easily be hidden behind the equipment and provides a simple solution for switching video devices. A L.E.D. indicator is provided on the front panel for visual; indication of what input is selected.
