SKU: CIR-DTMF16 Categories: ,


The DTMF-16 is excellent for controlling remote satellite receivers, network switching equipment, repeaters, or virtually any application where local control is inconvenient or impossible. Simply connect the DTMF-16’s bridging input across an audio line and it’s outputs will activate whenever a DTMF tone is received. The DTMF-16 is an inexpensive and convenient way to interface many news services to automation systems. For services using DTMF signals on voice channels, an inexpensive optional activation delay prevents false trips & mutes the audio during tones.

The Silencerâ„¢ equipped DTMF-16 takes its audio feed directly from your satellite receiver or other source. The audio output of the DTMF-16 feeds program audio to your console or switcher input. The control tones are automatically muted from the audio path. If your program material regularly contains Touch-Tones®, we will custom shift your control tones so that “normal” Touch-Tones pass through without muting.
