Arena Updates 1979 Audio System

The Coors Events Center at the University of Colorado Boulder may be nearly 40 years old, but the 11,500-plus capacity venue is kept up to date with regular upgrades, from its playing surface to its video production room, to its brand-new audio system, which replaced the original one that debuted with the venue’s opening in 1979.

Boulder, CO (November 3, 2017)—The Coors Events Center at the University of Colorado Boulder may be nearly 40 years old, but the 11,500-plus capacity venue is kept up to date with regular upgrades, from its playing surface to its video production room, to its brand-new audio system, which replaced the original one that debuted with the venue’s opening in 1979.

Key to the new system are Bose Professional RoomMatch DeltaQ line array components, chosen by Steve Pizzi, Assistant Athletics Director, Coors Events Center and Game Day Operations, and Jason DePaepe, Associate AD, Facilities and Game Day Operations, after they discovered them at a college facilities conference. Englewood, CO-based AV solutions provider AVI Systems tackled the project, working directly with Bose Professional.

As part of that, Bose and AVI developed a system that would accommodate different kinds of events; using Bose Modeler software, the design team tested a variety of speaker configurations, and even different seating layouts, in preparation for any potential future changes.

Ultimately, the venue now sports 15 arrays of RoomMatch modules configured from nine different combinations of horizontal and vertical waveguides. A full 10 arrays hang above the court, covering the audience seating bowl with two downward-firing arrays providing on-court coverage. In the main system, two arrays facing each side of the court are configured, from top to bottom, with two RM7010 RoomMatch modules to cover the upper seating and with an RM9020 and an RM9040 module below to extend coverage to the courtside seats.

At both the north and south ends of the court is a single array configured with an RM9010 cabinet at the top and three RM9020 modules below. Above each corner of the court, covering the wedge-shaped seating beneath, is an array consisting of an RM7010, an RM9020, an RM7020 and an RM5520 module. Two hangs each of two RM9010 modules directly above the free-throw lines deliver audio to the players and officials on the court. A single, centrally located line array of six RMS215 dual 15-inch subwoofers provides low-frequency extension.

A separate five-box array and a small delay array are intended to provide voice reinforcement for events taking place on the stage area at the arena’s north end. The single array is positioned directly above the north end basket and includes two RMS215 subs at the top, with one each of RM9020, RM12020 and RM12040 array elements below. A delay array of two RM9020 modules is flown toward the south end of the venue. A total of 40 RoomMatch Utility RMU108 two-way surface-mount speakers on a 70V distributed network are installed on the concourse level, in the restrooms, and at the building’s entrances. All of that is connected via an Audinate Dante-based audio-over-IP system for the entire building. Powering it all are three racks of eight-input Bose PowerMatch PM8500N configurable 4000 W amplifiers, and the system is managed and processed using a Bose ControlSpace ESP880 eight-channel digital signal processor fitted with a Dante card.
