Monroe Model R164 Stereo Audio/Video Switch module provides 2x1 (AB) balanced stereo audio follow video or IF/RF switching. The 2x1 switch will respond to a contact closure, a transistor switch to ground or a compatible logic level. The control input is buffered to eliminate high output current drive requirements of the controlling device. The R-164 can be controlled by Monroe Electronics’ program timers, remote controls or CATV Cue Tone receivers.
