Remote Audio Mixing Control with MutingThe D-RC type remote audio mixing controls provide user-accessible volume knobs for two or three sources. Each control is available with level controls only or with level controls plus a muting button for each channel. They function exactly as a mixer without the need to send audio to and from the remote location. A rear-panel RJ45 jack provides the connection for standard twisted-pair wiring between the remote control and an RDL remote-controlled mixer. The cable sends the knob position and muting status data to the mixer. All audio signals remain local to the mixer which uses VCA technology to set the mixer levels. A long life 10 kΩ potentiometer is used in the control for setting the VCA voltage. Muting models provide a MUTE button for each mixer channel that alternately mutes or un-mutes the audio. An LED MUTE indicator glows red when the signal is muted and turns green when the audio channel is active. Each model is offered in a standard RDL
