Norfolk, VA (July 29, 2011)--MacArthur Center Mall recently upgraded to a new audio system that includes QSC’s Q-Sys integrated system platform and CX series amplifiers.
Sound and communications systems specialist Independence Communications Inc., a Muzak affiliate, handled the upgrade at the MacArthur Center, a modern, upscale, 1.1 million-square-foot shopping center in the downtown Hampton Roads area of Norfolk. The QSC equipment replaced the head end of the mall’s original music playback and paging system.
The system upgrade includes a Q-Sys Core 1000 plus two I/O Frames, with a total of eight CX Series amplifiers feeding the previously installed 70V loudspeaker system. Three CX1201V, one CX602V, and two CX302V two-channel amplifiers provide power to speakers in the mall’s various courts, common areas, hallways, and offices. Two CX204V four-channel amps drive eight zones in the multi-story parking garages located at the north and south ends of the mall. All of the amplifiers include a DataPort connector that enables system-wide networking of telemetry and supervision via Q-Sys.
The new system also makes use of Q-Sys Designer’s UCI software tool, which allows custom control panels to be created for use on handheld Wi-Fi devices. “The mall’s engineer uses his iPad and an internet connection to go out and make level changes or whatever he needs to do,” says William Ammerman III, Director of Engineering for Independence Communications. “They’re also set up so that if there’s an amplifier fault outside of a certain range that we put in for impedance or temperature, I can send him an e-mail and let him know that there’s an issue at the rack.”
Five sensing microphones located throughout the mall--in the food court, two common areas, and outside the two main anchor retail stores--provide information that allows Q-Sys to control ambient sound levels. The system plays background music supplied by Muzak and also supports three paging inputs. There’s a telephone page and two microphones, one at the equipment rack in case of emergencies and another in the security area.
