ISP Technologies Pro Audio was recently featured in Systems Contractor News for the installation at Jimmy Johns Field, home of the United Shore Professional Baseball League in Utica, Michigan. ISP teamed up with Southfield, MI-based Bluewater Technologies for the installation.
In specifying the sound system for the 4,000-seat stadium, Bluewater kept things local, choosing Waterford, MI-based ISP Technologies for all of the loudspeakers, which cover the 22 suites, cabana and picnic areas, and the grass berm seating area. “We approached ISP and asked what we could do for a stadium system,” said Randy Hall, systems design engineer at Bluewater Technologies. “We involved the manufacturer and put together a system that sounds really good.”
“ISP worked with Bluewater to custom develop 19 CX Series coax speakers, which were hung along with four XMAX 218 subs to provide 23,000 watts of power to cover the field area with professional level sound. For the suites, concourse, and restaurant, ISP and Bluewater decided to use the manufacturer’s High Definition Distributed System (HDDS) line of loudspeakers, which feature an integrated design for simplicity.
ISP Technologies loudspeakers cover the 22 suites, cabana and picnic areas, and the grass berm seating area. “The [HDDS] cabinets have the amplifiers built directly into the speakers, so there’s no loss of fidelity across the speaker line,” Hall said. “They distribute it over Category 6, and depending on each speaker’s current load, will depend on how many speakers you can connect to that run. We use two speakers per run, and ran a Cat-6 out there and jumpered it over to the second speaker. And we did it in different zones, so all of the delays would match up.” And since all of the HDDS speakers are powered by the same Cat-6 cable that carries the audio signal, installation process was simplified, as well. The audio system is controlled by a Soundcraft Si Expression 2 board, and the digital signal processing is done via a Biamp Tesira SERVER-IO.”
