Lakeview Baptist Church Gets System Overhaul

This story begins six years ago, when Lakeview Baptist Church, in Auburn, Alabama, contacted dB Audio and Video owner Mike Hedden to assess their less-than-pristine acoustics. Church members had been complaining that substantial portions of the Sunday service were unintelligible and that the music was muddy and uninspiring. Hedden took TEF readings of the 1,800-seat, 50-foot-ceiling sanctuary and confirmed analytically what he had suspected intuitively. The room's untreated, near-parabolic rear wall, nearly 200 feet long and 80 feet from the stage, was focusing all of the energy from their late-1980s era, "honky-stadium" compression driver horns back at the stage. He measured higher SPLs in the choir loft than he did in the middle of the room.

Lakeview Baptist

Lakeview Baptist Church, in Auburn, Georgia, is the latest dB Audio and Video system design featuring Danley Sound Labs speakers. The center cluster is comprised of two TH-115 subwoofers, two SH-50s hanging below with a single Danley SH-100 for front fill.

Unfortunately, forces conspired at the time to keep the church from moving on improvements, and they muddled through with their existing sound system until a new minister of music arrived in 2005. With an orchestra in place, Lakeview already offered a decidedly blended style of worship, but the new director upped the energy, allowing the rhythm section to lead three-quarters of the service. The long-standing problem had reached its tipping point. Something needed to be done.

This time dB Audio and Video's System Designer, Keith Armstrong, led the project. Starting with Hedden's original measurements, he laid out a dramatic plan for improvement. "We always start our jobs by considering the acoustics," he explained, "because you can't overcome a physical flaw with electronics. Once the acoustics are well behaved, carefully chosen reinforcement that complements the space can make an otherwise adequate system into a stellar system. With Lakeview's situation, it was clear that we had to do something about the rear wall first and foremost."

Armstrong's solution was to the point, brutish, but singularly effective in a way that any more nuanced approach would not have been. He covered the areas above, below, and on the leading edge of the rear wall balcony with 4' x 4' two-inch thick absorption panels. The panels easily cut most of the energy above 1kHz and a good deal of the energy below that frequency. "The rear wall delay that had been the bane of their services was reduced to almost nothing," Armstrong reported.

There was another acoustical flaw that Armstrong felt compelled to address. "The original designer had placed diffusion panels above the stage," he explained. “But they had been installed upside down. Instead of diffusing sound away from the stage, their flat backs focused everything right back at its source. The last thing you want is energy going straight up and down like that, slapping back and forth." The fix was obvious and was affected with the help of free church labor.

With the acoustical problems under control, Armstrong shifted his focus to the antiquated reinforcement system. "Their existing compression driver horns had no pattern control at all," he said. "They were splashing energy all over the place. If we had left them in place or settled for their similarly sloppy contemporary descendants, the side walls would have needed treatment as well." Instead, Armstrong opted for Danley full-range loudspeakers, which use proprietary Synergy Horn patent-pending technology to deliver steep drop-offs outside their prescribed pattern and naturally-phase coherent, high-fidelity sound.

Armstrong designed an exploded mono system with a center cluster composed of two 50 deg. x 50 deg. Danley SH-50 full-range loudspeakers. A single 110 deg. x 110 deg. Danley SH-100 provided front fill for the massive room. A pair of SH-100s 45 feet to either side of the center cluster provided side fill. A delay ring of three, SH-100s situated between the stage and the FOH position covered the balcony. Finally, a delay ring of ten Atlas SM52TS 70-volt loudspeakers provided reinforcement underneath the balcony.

Armstrong commented, "The Danleys were perfect for this installation because we had to be absolutely sure that their patterns would be true to the angles we set. We've used speakers from other manufacturers who claimed to have tight pattern control. But when you go below 500Hz, all their pattern control was lost. The Danleys have remarkably consistent pattern control across the entire spectrum. We set our angles and kept everything off the side walls."

In addition to the full-range loudspeakers, Armstrong floated two Danley TH-115 subwoofers above the center cluster. "Lakeview's volunteer sound engineer stressed that the new system should have truly excellent bass," Armstrong added. "The Danley subwoofers are second to none when it comes to clean, loud low-end. To ensure that their engineer was happy, I put the sub output on an aux send. If he wants more bass, he has total control."

In addition to front-of-house sound, Armstrong revitalized Lakeview's monitoring system and, per the pastor's request, did away with the clutter of floor wedges. He flew a Danley SH-100 for the pastor and two SH-100s for the choir. An eight-station Aviom personal monitoring system provides custom mixes for the orchestra members.

QSC RMX-Series amps power all of the Danleys and include 5050s for the TH-115 subwoofers, 4050s for the SH-50s, and 2450s for all of the SH-100s. An RMX 850 interfaced with a Peavey Automatch transformer powers the 70-Volt under-balcony speakers. A Biamp Audia Solo 4 x 12 DSP fed by a Yamaha M7 C148 console provides a stunning front-end to the system.

The church and its members are amazed and impressed by the new treatments and the new system. "It's a completely different animal now," Armstrong laughed. "Gone are the reflective surfaces and the muddy compression drivers. Church members have commented that they're hearing things they never heard with the old system. Beyond sheer intelligibility, the new system has a lot of punch. A group of kids from Auburn University worship there on Thursdays, and you know they push it. We easily did 110dB in tests, and with the Danleys, there isn't a trace of distortion.”

Management Buyout Signals New Push Ahead for DiGiCo

DiGiCo announces their new management team comprising of Chief Executive, Bob Doyle, Managing Director, James Gordon, Marketing Director, David Webster, Technical Director, John Stadius, and Company Secretary, Helen Culleton.

Having taken over the mantle of Managing Director from Doyle in January, this was Gordon’s first significant project in the role. “We’ve always been a reactive and pro active company that understands the market place we’re in,” says Gordon. “However, when you have external investors, there is a need to explain the ins and outs of decision making processes and that can slow things down.

“The management buyout removes that requirement and means we can focus more of our time on doing what we do best, making us an even more agile and focussed company.” Gordon adds.

Along with a number of plans yet to be revealed, DiGiCo will be putting a share incentive scheme in place for its employees. “It’s nice that as a modern company we’re able to reward the people that work with us and put in the extra time,” continues Gordon. “We have a lot of staff that work 24/7 for the benefit of this company and they will now be able to share in the success with us fully.”

“Lots of companies evolve as we did,” adds Doyle. “It was necessary to introduce shareholders into the mix to make the initial purchase of the company back in 2002. But now, those whose hard work over the last five years has enabled the company to reach a position to where a buyout was a reality, need to be rewarded with equity ownership so that we can take things to the next stage in company development and growth.”

“The potential of what we can achieve with the technology we have within the company, both current and future, is amazing and I thank John Stadius for that every day,” says Gordon. “The enthusiasm and drive for success that has got us this far is back to where it was when we started in 2002 and will carry us forward.”

Multidyne
MULTIDYNE UTP CAT 5 LINK FOR RGB/UXGA VIDEO AND STEREO AUDIO

Multidyne's TP-RGB-1000 transports RGB/UXGA and stereo audio over more than 1000 feet of UTP CAT 5, 5e and 6 cables. The system supports UXGA resolutions of up to 1600 by 1200 and includes automatic equalization and anti-skew technology. The anti-skew feature permits video transmission over inexpensive data grade twisted pair cable. Expensive non-skew cable is not required.

The TP-RGB-1000 receiver unit has a Daisy-Chain or repeater option. One RGB/UXGA source can be daisy-chained to multiple monitors. Also, the TP-RGB-1000 supports computer video graphical input signals on a female 15-pin HD connector and transmits the video on a shielded female RJ-45 connector. The unit also accepts PC audio on a 3.5 mm stereo mini jack.

Another feature of the TP-RGB-1000 is that it supports video with 15-130 kHz horizontal scan rate and a 30-150 Hz vertical scan rate. The system is compatible with nearly every video graphics format.

The transport of high resolution video over long distances on data grade cable causes a problem known as skew. Skew causes distortion in the image which results in image convergence problems in the red, green, and blue color spaces. One solution is the use expensive non-skew cable. The TP-RGB-1000 includes advanced anti-skew technology that automatically corrects skew problems and distortion. Twisted pair transport provides the capability for the separation of a video signal source and the monitor. For example, a computer or imaging device can be in a different location than the monitors. In many applications space is limited in the monitor area. With flat screen technology, very little space is required. The computers or imaging devices can be in another room. Systems are available to transport HDMI, DVI or RGB video as well as audio, keyboard, and mouse control.
