The RS-103A was designed to be the most versatile 10 x 1 routing switcher available. Excellent signal quality, remote control options and RS-422 control capability has been engineered into these switchers. Multiple switchers can be linked together via the Videotek Data Bus to form various configurations such as matrix, component and expanded input systems. Video only or three channel audio-follow-video applications may be built with the RS-103 series. As system requirements change, these switchers may be field-upgraded to new configurations.
