round dais, and the front of the dais is raised about 12 inches above the actual work surface,” Cyree says. “It’s designed to look like elegant yet simple wooden furniture. From the audience’s point of view, the monitors sit just slightly above the wood. You can hardly see them.” The monitor inputs come from the equipment room next door. It is equipped with a Denon DN-C310 professional DVD player, an Extron CrossPoint 300 124HV 12x4 RGBHV/audio switcher, and an Extron DVS304A four-input video and RGB scaler with audio switching. Signals from the three laptop stations — one at the center dais (mayor’s position), and one each on the two staff tables facing the dais — are fed into this room, then distributed to the monitors in the chambers. “Since we had to feed seven monitors on the councillors’ dais using a small conduit, we decided to send a single feed into the dais, then amplify/split the signal at that point using a Kramer VP-15 distribution amplifier,” says Cyree. “This allowed us to effectively feed all seven monitors using a single piece of coax cable.” Audio is played through a QSC CX108V 100-watt, 8-channel amplifier located in the equipment room, and fed to JBL Professional Control 26CT ceiling loudspeakers. Each of the councillors has his or her own Shure MX418S/S gooseneck microphone, and there is one located at each of the two staff tables; providing nine in all. “The audio levels are automatically balanced by the Biamp Nexia CS digital signal processor, which has 10 mic/line inputs and 6 mic/line outputs,” Cyree says. “This means that no one has to manually balance the levels; keeping things nice and simple, as the client requested.” The audio from each meeting is recorded using a Marantz PMD-570 Pro digital recorder. This is a solid state recorder that dubs directly to removable Flash memory cards. After the meeting is over, the card is removed and taken to a clerk. They insert it into the clerk’s PC and make a transcription using Windows Media Player. The audio is then dubbed to the city’s server, with the Flash card being stored in the city archives. To provide audio to the hearing impaired, the Council Chambers have been equipped with a Listen LT-800-216 stationary transmitter, LR-400-216 display receiver, and LA-165 wireless headsets. For $135,000, the City of Aliso Viejo has transformed its city council AV system from primitive to professional. “For what we got, we believe this to have been money well spent,” says Yasui.
