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. Unit can also be
operated manually. AC Power adapter Included.
