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 may be desired for multiple isolated feeds.
3) Connect an automatic or mic/line mixer, such as a BIAMP
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 suitable location.
