Crown Audio CTs Series Amplifiers Network Control Technologies Power Audio Intelligibility At Wukesong Indoor Stadium For 2008 Summer Olympics

Demonstrating the performance consistency and system reliability of Crown Audio’s CTs Series amplifiers in concert with the efficient network capability of Crown’s IQ Series network cards, Beijing’s new 18,000-seat Wukesong Indoor Stadium, home to the basketball competitions at the 2008 Summer Olympics, features a complement of three Crown CTs600 amplifiers, two CTs1200 amplifiers, two CTs3000 amplifiers networked via seven Crown IQ3-PIP-Lite cards and Harman’s HiQnet™ system configuration and control protocol. The networked amplifiers drive 22 JBL Professional Control 29AV-1 loudspeakers.

Situated in Western Beijing, the 63,000-square meter facility was completed in January 2008 and after the Olympic basketball preliminaries and finals will become a major cultural, recreational center for the citizens of Beijing, integrating cultural, sporting and commercial facilities with large-scale gardens and green space.

The audio design required engineers to specify and install a system that would sound great despite the resonant surfaces of the large space. Bcause the system would enjoy a second life after the games reliability, scalability and versatility needed to be balanced carefully with the budgetary limitations.

“The Crown CTs Series is a proven performer for installed sound applications and, together with the JBL Professional loudspeakers, will provide Olympic basketball fans and the citizens of Beijing with quality audio for years to come,” noted Marc Kellom, Vice President of Marketing, Crown Audio. “And because CTs amplifiers are so easily networked using IQ-PIP cards and HiQnet, the system is optimally configured for the games but can be easily configured and controlled for many future applications via the HiQnet™ System Architect™ user interface.:”

Crown’s CTs Series amplifiers provide exceptional performance, flexibility and value for installed sound applications. CTs Series amplifiers feature independent selection of high and low impedance operation for a specific channel, plus power levels and features that were carefully chosen to match the requirements of fixed install design. Crown Audio PIP Lite integrates Ethernet-based network control via 100-Mb TCP/IQ protocol for digital control of analog devices with digital signal control for error trapping, proactive response and remote load monitoring.

Harman HiQnet™ is the world's first connectivity and control protocol that integrates all product categories in the signal chain for professional audio systems of all types, size, and applications. Harman HiQnet no longer requires the user to manage multiple disparate operating systems or be responsible for programming individual signal processors, speaker controllers, wireless microphone systems, and mixing consoles. HiQnet was developed by engineers from across the Harman Pro Group and is coordinated by the System Development and Integration Group (SDIG), a team of dedicated systems specialists based in Salt Lake City, Utah.
