Pro Audio Review - June 2008 - (Page 42) CONTRACTING | Installation Profile PRUDENTIAL CENTER Continued From Page 41 puts from the FOH mixer to a comprehensive Peavey MediaMatrix NION-based DSP that handles system routing and signal processing. All of the Crown amplifiers also connect to the Media Matrix system via a CobraNet I Gbit Ethernet network. The sound-reinforcement system is run in mono. Crown I-Tech Series power amplifiers feature integrated DSP, peak-voltage and RMS power limiting to protect connected loudspeakers, in addition to remote monitoring and control via integral Harman HiQnet, plus a front-panel LCD readout that provides diagnostics plus preset selection for fast and easy system setup. “Remote control and monitoring of all of the amplifier channels via HiQnet is a great bonus,” stresses Prager. “Using a [Crown-developed] GUI we can set input and output levels and turn groups of amplification on and off. During different events at the Prudential Center, the owners might decide to run different PA configurations, dependent upon the audience size and location within the space. With either of the two redundant control PCs – one at the sound-mixing location and the other within the equipment racks – an operator WJHW Project Consultant Kevin Day testing the PA announcer's microphone. can monitor and verify amplifier status for any system re-configuration within seconds.” The PIP Lite add-on card provides HiQnet control/monitoring for CTs Series amplifiers via IQ Network and IQwic software. And there is another benefit of remote monitoring, the project engineer adds. “Aside from checking input and output levels via HiQnet, the operators can monitor load and thermal BSS Soundweb and Dolby Lake loudspeaker controllers. conditions – and see error-reporting messages – which mean that they can be alerted when a loudspeaker is removed from the system. While loudspeaker theft isn’t foreseen as a major problem, it’s a very useful feature!” HiQnet is available on a number of amplifiers, signal processors, loudspeaker controllers, wireless microphones and consoles; it was developed by the Harman Pro Group System Development and Integration Group (SDIG), based in Salt Lake City, UT. All audio-system routing, equalization, delay and metering are handled by the facility’s multi-element MediaMatrix. “The MediaMatrix control system is distributed throughout the Prudential Center,” Prager continues, “with chassis located close to sound-critical areas. There are six units in the catwalk adjacent to the amplifier racks; two in the Sound Control room; one in the Fiber Core main rack; and one in each of the tech- 42 | ProAudio Review | June 2008 www.proaudioreview.com http://www.sonicus.net http://www.sonicus.net http://www.proaudioreview.com
