CHANNEL SELECT

1) Connect Zone Output to the input of a teleconferencing system. This allows interactive meetings, training seminars, and presentations to be fed to remote locations. 2) Connect Main Output to the inputs of the amplifier driving the boardroom speakers. A separate tap from Main Output can be used to feed the audio inputs of a VCR, when recording training seminars or presentations for future viewing. A distribution amplifier, such as a DA28R, may be desired for multiple isolated feeds. 3) Connect an automatic or mic/line mixer, such as an autoTWO or 801i to the Mic/Line Input. Connect a wire across the ‘Mute’ & ‘Signal Present’ terminals for voice-activated muting. 4) Connect the stereo line-level program sources to Inputs 1~4, and adjust Level 1~4 (reduce level only on inputs which are higher than the others). 5) Adjust Main Level, Zone Level, and Limit Threshold for desired maximum levels. 6) Set microphone mixer output level. Set Trim & Pad so the +10 indicator flashes only on occasional peaks. Adjust Mic Level for desired overall microphone levels. 7) Connect an optional Controller to the Remote terminals. Mount the Controller in a location to accept push-button and/or infrared commands.
