CHANNEL SELECT
This diagram shows a VSX41 used for video source selection in a "sports bar" application. A similar system could be used for classroom
applications. The VSX41 Remote Output is connected to an ADVANTAGE
units. Wall-mount and/or infrared remote controls provide simultaneous "audio-follow-video" switching of sources, as well as a master
volume control. The VSX41 receives video input signals from satellite, cable, VCR, etc., and sends a single output to a large-screen video
monitor or projector. The SPM412e receives stereo audio input signals from the same sources, and sends a stereo output (with remote
volume control) to the main sound system, as well as providing a mono output for a zone sound system. In addition, the SPM412e
provides an input for a paging microphone, which includes automatic "page-over" muting of the audio signals.
