Chicago, IL – August 2010… With the summer concert season in full swing, music enthusiasts everywhere are enjoying performances by their favorite artists. Nowhere is this more evident than at the Country Club Hills Theater, an outdoor venue situated in Country Club Hills, a suburb of Chicago. Known as the number #1 R&B venue in Chicagoland, this summer’s schedule includes performances by Toni Braxton, Al Jarreau, Eric Benet, Bobby Brown, David Sanborn, and Smokey Robinson. This season, the audience and performers alike are really upbeat about the venue’s sound quality—thanks to a new sound reinforcement (SR) system comprised of components from D.A.S. Audio’s Aero Series 2 catalog.

Chicago, IL-based Sound of Authority, Inc., a provider of sound reinforcement services for concerts and special events and a design/build firm for the installed sound market, was contracted to provide the sound system at the Country Club Hills Theater. Ernest Greene, Sound of Authority’s President and CEO, deployed a brand new SR setup consisting of D.A.S. Audio’s Aero 50 line array enclosures and LX-218 subwoofers from the Aero Series 2 product group, augmented by Aero-12A line array modules for side fill. He discussed the challenges of providing sound at the venue.

“This is our third season handling sound services for the Country Club Hills Theater,� Greene explained, “While our client has always been happy with the sound reinforcement services we’ve provided, I’m always looking to improve upon what we’ve done previously and this led to the purchase of our new D.A.S. Audio Aero Series 2 system. The Aero 50 offers a higher output level than what we used previously and this made it that much easier to provide consistent coverage throughout the audience areas.�

The new SR system at the Country Club Hills Theater consists of twelve Aero 50 line array enclosures—flown six modules per side at a trim height of roughly fourteen feet. The two loudspeaker clusters are positioned approximately forty feet apart and are augmented by eight D.A.S. Audio LX-218 subwoofers; ground stacked four enclosures per side in a 2 high by 2 wide configuration. The Aero 50 is a 3-way, large format line array module incorporating dual 15-inch LF (low frequency) transducers, four 8-inch loudspeakers for the midrange, and two neodymium compression drivers with 1.5-inch exits for the high frequencies. The LX-218 sub bass enclosures are high performance systems incorporating two D.A.S. Audio 18LX long excursion transducers in a front loaded, bass reflex configuration. Both loudspeaker systems are driven by Crest Audio Pro II Series 8002 power amps.

For side fills, the Sound of Authority crew placed four D.A.S. Audio Aero Series Aero-8A self-powered, 2-way, line array enclosures. These cabinets are positioned close to ear level—two units per side.

Greene reports the new SR system, which will remain in-place at the Country Club Hills Theater through late August, is delivering everything and more than he originally envisioned. “We took delivery of the new equipment on June first and began installation on June 3rd,� Greene said. “In addition to a dramatic improvement in sound quality, I’ve been equally impressed with D.A.S. Audio’s customer/technical support services. In preparation for our first event on June 5th with R&B vocalist Toni Braxton, D.A.S. Audio’s Carlos Henao, the company’s U.S. Accounts Manager, paid us a visit to ensure the new equipment was operating as expected and helped us optimize the system to the venue. The company’s customer service is first-rate.�

Accolades continue to pour in from all directions. “Our client is absolutely ecstatic with the system’s sound quality, the audiences have been equally complimentary, and the sound engineers that mix for the various artists have been very impressed. The D.A.S. Audio system has great dynamic range, delivers very musical reproduction with a high level of speech intelligibility, and delivers impressive output. With the new equipment’s sonic performance, coupled with D.A.S. Audio’s first rate customer service, I can’t think of a single reason not to deploy D.A.S. Audio.�
