About the System 7SC

What is the System 7SC?

The System 7SC is a seven input, configurable switcher with a built-in video scaler and projector control ability.

The System 7SC provides central control and integration for small audio/video (A/V) installations. It offers video and audio switching, room controls, and projector control. Each of these functions can be controlled at the front panel, by a hardwired control pad, by infrared remote control (the IR 701), or via RS-232 control.

The switcher can control video and audio input settings; display functions such as power, video mute and video modes; and execute relay/room functions, such as lowering or raising display screens or powering lights on or off. The System 7SC also has the ability to “learn” infrared projector control commands.

The System 7SC accepts computer-video (RGB), component video, S-video and composite video, and each input is separately configurable. The switcher also accepts seven line-level, balanced or unbalanced stereo audio inputs.
