MILWAUKEE, WI — Sven Pro Sound (SPS) recently completed a major audio upgrade at Eastbrook Church. Four different small to large venues within the church were upgraded with a wide variety of products. The largest venue upgraded was the church’s main worship hall. SPS designed a dynamic sound system that included d&b audiotechnik’s Q-series speakers and D12 amplifiers. SPS also made use of d&b’s ArrayCalc modeling program.
More details from d&b (www.dbaudio.com/en.html):
The old speakers were mounted on large uni-strut beams. In addition, the church is very wide and has tall ceilings, bringing in reverb time to around 2 seconds. Because of the capabilities of the Q10 speakers, only three were needed to cover the all of the floor sections. Two QSUBs were flown in the center to provide even bass for the entire room and two 8S speakers were mounted for upper balcony fill. All speakers were mounted directly to the building, enabling the large uni-strut beams to be removed. All the speakers are powered by three D12 amplifiers providing EQ, limiting and delay for the system. This design enabled SPS to be considerably less costly than other competitors while still providing touring-grade equipment capable of concert-level volume without limiting. The speakers are configured so that wherever one is standing and hearing two of the three speakers, which is the majority of the space, one would get stereo sound. In addition, two MAX 12 monitors were flown for stage monitoring for the choir, which sings biweekly.
A second venue upgraded was a multipurpose gym that was plagued with a acoustical problems since it opened. The church leadership considered adding major acoustical treatment to the room to reduce the echo but SPS encouraged them to wait until the poorly-designed sound system was addressed. SPS suggested two highly directional speakers pointing across the room to avoid reverberation off the walls. D&B Audiotechnik’s product line was the clear choice due to its superb sound and directionality using minimal power. The system would be used not only for speech but for live music youth nights and recorded dance and rap music at basketball games. After running D&B’s ArrayCalc software to predict coverage and SPL levels in the room, the perfect solution was a pair of D&B Audiotechnik E12 speakers mounted horizontally at precise angles powered by a single D&B Audiotechnik D6 amplifier. This design ensured the speakers’ tight and even dispersion pattern was not hitting any of the walls and was only directed to the floor and bleachers. SPS worked with the church to trade-in their existing, obsolete system. The trade-in had enough value that the client didn’t spend any money on the new D&B system.
Another venue upgraded was a multipurpose hall used for primarily church meals and large roundtable events. Like the multipurpose gym, the sound system was inadequate for the room and was poorly designed. An abundance of speakers all pointing inward caused feedback from microphones. Like the gym, SPS took the approach of less is better. An audio system with D&B Audiotechnik E8 speakers powered by a D6 amplifier greatly enhanced the sound quality. There is an increased amount of headroom and with the built-in protection in the amplifier, the speakers are protected against abuse. Often listeners wonder if there are subwoofers present in the room because of the dynamic range of the E8’s but in fact bass was tuned out of the system during installation.
The final venue upgraded was the church’s coffee shop, Holy Grounds which serves commuters, the community, Eastbrook Academy students, teachers, and churchgoers. The coffee shop is used for live acoustic performances, but its basic, low-quality sound system elicited complaints for inconsistent coverage and a lack of clarity. The church was looking for a durable, high-quality yet unobtrusive sound system for higher-volume and more bass-heavy open mic nights and turned to SPS for a reasonably-priced solution. Sven Pro Sound provided a D&B Audiotechnik E series sound system consisting of two E3 speakers, one E12-SUB subwoofer and three E-PAC V3 amplifiers. The system was tuned using d&b’s internal equalization and delay in the amplifiers. The church has credited Sven Pro Sound for providing a system that literally disappears in the rafters yet has plenty of volume and power to fill the entire space with clean, clear sound. They have never once run into the limiters on the amplifiers.
SPS has received countless compliments from professional engineers, church members and musicians on each of the sound systems. SPS regularly demoes all four sound systems and every time the listener is blown away by the clarity, power and accuracy of the sound from each audio system.
