StereoSwitchtm 

StereoSwitch is a handy audio switcher thatÕs perfect for switching between studios, selecting audio sources. If youÕve used up all the inputs on your console, feed infrequently-used sources into StereoSwitch and select between them. StereoSwitch can also be used "in reverse", as a router, to send a source to one of three destinations.

3-INPUT STEREO AUDIO SWITCHER

Product Description

StereoSwitch is a three-input stereo audio switcher. It accepts up to three stereo balanced audio sources, selecting one to be routed to the stereo balanced output. It is ideally suited for numerous broadcast applications, e.g., as a studio switcher, line selector, or for automatic source selection under the control of a broadcast automation system. StereoSwitch utilizes sealed relays with gold-plated contacts for audio switch- ing. There is no circuitry in the audio path,making StereoSwitch totally transparent to the source. The unit can be controlled with any momentary or maintained contact closure, open collector, TTL/CMOS logic, or DC voltage from 5-24 volts. Internal power-up programming permits the user to determine which of the three inputs is automatically selected when AC is applied. Tally outputs are provided to drive remote status indicators. Inactive sources can be automatically terminated.
