Calvary Chapel in Melbourne, Fla. recently upgraded their sound system with Turbosound Flex Array loudspeakers powered by Lab.Gruppen PLM Series amplifiers with on-board Dolby Lake processing. System was designed and installed by Atlantic Pro Audio of Altamonte Springs, Fla.

Calvary Chapel Expands With Road-worthy Sound

The need to connect with an audience is a vital concern in any application, but all the more so in a house of worship. “It’s a recurring theme,” says Craig Beyrooti, designer of Calvary Chapel’s new system in Melbourne, Fla., and head of Atlantic Pro Audio, the design/build contractor for the audio install.  “I’ve been told this so many times by worship leaders that they need to connect with the audience and it’s absolutely vital for the engineer and the sound system to enable them to do that. They have to have clarity and dynamics,” he continues. “Loud sound that doesn’t rip your head off. That you can sing along with, full voice, to be able to join in the worship.”

Over the course of the past year, Beyrooti has been exploring the possibilities for creating a system for Calvary that does just that. The impetus for the build was the construction of another worship facility, into which Calvary’s pre-existing system would be placed. At the initial Melbourne campus, with its balcony seating area and 3000-seat capacity, the idea was to provide a slightly more powerful system.

In the end, Beyrooti specified six Lab.gruppen PLM 10000Q/BP’s power amplifiers giving life to a Turbosound Flex Array made up of 24 TFA-600H’s, 12 TFA-600L bass cabinets and TCS-61/106’s and – two NuQ-10’s. A Dolby Lake processor is also part of the loudspeaker’s signal chain, chosen for their flexibility, power, superior sonic purity.  “The high channel count, and, of course, the quality of the Labs is second to none. Once we got the system installed and fired up, it was fantastic.”

Many large modern houses of worship increasingly depend heavily on technologically advanced systems and experienced techs to run them, but what sets Calvary Chapel apart, says Beyrooti, is the real world experience of Senior Audio Engineer, Greg Branch. “He’s been out on the road for years and has experience with real world use of the PA. He really understands the importance of good sound.” In fact, Branch took the gig at Calvary five years ago to be able to spend more time at home, after stints as Bebo Norman’s front-of-house engineer, and as a tech on tour with American Metal Core giants, Sevendust.

“There are many good amplifiers out there, but Greg really liked the idea of having [the functionality of the Lake controllers],” says Beyrooti. “If he wants to time align the PA he can do it collectively as one system, using the Lake controllers versus getting into each component.”

House of worship and theater installs are a major part of Atlantic Pro Audio’s business and Beyrooti and APA pride themselves on not being simply a one size fits all solution for their clients. Offering instead, decidedly personal, customized service that speaks directly to individual client’s needs.

Part of what appeals to Greg Branch about Calvary Chapel, is the fact that both the size and scope of the chapel’s system, and the sheer number of bodies in the seats is comparable to what he’s become used to on the road. “I’ve always been a fan of Labs, but what really led me to them was Lake onboard,” says Branch. “I’ve always used Lake processors, pretty much everywhere I’ve gone. With the on-board DSP, the flexibility of the amplifiers, you can virtually do anything with them you need to. It just makes sense.

Beyrooti says it was a simply matter of the correct tool for the job. “The clarity, definition, the transient response, the damping factor – it’s a great sounding rig,” he says, referencing another Turbo Sound system that exists as part of APA’s rental inventory. “"Turbosound Flex Array is an awesome system and powered by Lab PLM's is about as good as it gets."

Durham Festival of Light Features Stunning Cathedral Display

E/T/C UK's Ross Ashton designed a specially commissioned projection artwork for Durham Cathedral as part of the four-day "Lumière" Durham Festival of Light event.

E/T/C UK's Ross Ashton designed a specially commissioned projection artwork for Durham Cathedral as part of the four-day "Lumière" Durham Festival of Light event, curated and co-ordinated by Artichoke. Ashton's work, "Crown of Light", covered the entire North fascia of the Cathedral including all sides of the three towers, It was the largest installation of the festival, and arguably also the biggest cathedral projection to date in the UK.

Durham Cathedral dates back to 1093 and is regarded as one of the finest examples of Norman architecture in the country. It is a designated UNESCO world Heritage Site along with nearby Durham Castle which faces it across Palace Green.

Ashton received an initial brief from Artichoke's Helen Marriage and Nicky Webb about the narrative and direction of the show. Taking these as a creative starting point for the storyboard, he then input and developed his own ideas.

The story encompassed the history of the cathedral including the Lindesfarne Gospels, noted for their amazing accompanying imagery and spectacular Celtic calligraphy. These were originated by the Lindesfarne Monks and stored in Durham Cathedral for many years, along with the bones of St Cuthbert which still reside there. Ashton's piece also explored the building as an architectural space and its relationship with and historical significance to the city.

He and Paul Chatfield evolved the PIGI projection artwork using high-powered digital projectors and large-format film strips over a period of two weeks, simultaneously collaborating with musical director Robert Ziegler who compiled a soundscape for the 16 minute show, and sound designer John Del'Nero who designed the audio system.

Ashton used material sourced from the British Library and also conducted a photo shoot at the Cathedral to capture all the architectural and structural elements he wanted to incorporate into the show.

The projection system utilized 7 x PIGI 6KW machines with double rotating scrollers, positioned at various distances around the Cathedral - the longest throw distance was 150 meters and the shortest just 20 meters. This was meticulously calculated to eliminate any shadowing from the numerous trees dotted around the Cathedral Gardens - and was also one of the major creative and technical challenges of the project.

The seven projectors were in six different positions, fitted with five different types of lens, ranging from a 10 cm wide-angle lens to an 85 cm long throw lens. The seven different positions each covered a separate zone of the cathedral's architecture.

The PIGI film scrolls were all approximately 15 metres in length, and the PIGI artwork was assembled and pre-corrected for perspective and keystoning in Photoshop. The show was programmed into E/T/C's PC-based OnlyCue controller and operated by Karen Monid. It featured some fabulously smooth movement dissolves, transitions and other subtleties for which the OnlyCue and PIGI combination is known and loved.

Ashton comments, "It was a huge honor to be asked to create and present this piece. Durham is one of the country's signature Cathedrals. It's a wonderful site with a fabulously rich history and is a very special location in which to work".

The E/T/C London crew of Richard Porter and Michael Barry started rigging the projectors on the Tuesday ready for a Thursday night opening. The PIGI's were all housed in custom weatherized sheilds also supplied by E/T/C.

This show - which ran eight times nightly, and the other Lumiere installations involving over 50 UK and international artists, proved a massive success, drawing up to 75,000 people into the city centee each evening despite some appalling weather. Collectively, they created an imaginative and stimulating environment for the enjoyment and engagement of people of all ages, interests and backgrounds.

The Festival of Light will now become a regular event for Durham. Ross Ashton is also designing projection artworks for the forthcoming St Andrew's Festival of Light in Scotland at the end of November, and has recently completed installations for the 2009 Pittsburg Festival of Light in the US and Rheinpartie 2009 in Germany. In January, he is presenting another special commission for the Closing Ceremony of Cambridge 800, an event that has celebrated the 800th anniversary of the University.

Sennheiser Mics Inspire at Catalyst Conference

Over 13,000 new church leaders at the recent Catalyst Conference in Atlanta’s Gwinnett Arena listened to over a dozen bands using the new Sennheiser SKM 2000 wireless vocal microphones.

For nearly a decade, The Catalyst Conference has been inspiring and guiding the next generation of church leaders. From a modest 1,500 attendees in its first year, the annual event has grown tremendously, with a capacity crowd of over 13,000 leaders packing into the Gwinnett Arena in Atlanta, Georgia for this year’s two-day event. Dustin Whitt mixed front-of-house for over a dozen bands in those two days, relying on four Sennheiser SKM 2000 wireless vocal mics, ten Sennheiser ew 300 IEM G3 wireless personal monitors, and a complete Sennheiser evolution 900 Series drum mic kit with MKH 8040s for overheads.

Whitt is the audio director at Buckhead Church in Atlanta, the nation’s third largest church (and gaining!) and co-founder of OwnTheMix.com, an online audio training solution for the modern church and winner of Worship Leader Magazine’s 2009 Editor’s Pick. The Sennheiser SKM 2000 advances the RF leader’s technology to deliver auto-tuning capability and ever-more robust RF performance. “Having previously demo’d a 2000 system, I fully expected that the SKM 2000 would be the perfect tool for this job,” says Whitt.

“What I didn’t expect,” he continues, “was to be so completely blown away by the MMK 965 condenser capsule. It seems to punch through a mix in the most pleasing way. It’s not harsh or painful in the least, but rather a perfect blend of clarity, presence and warmth.” Whitt observed that vocalists seldom get too excited about the gear they have to use, and their banter is usually about new bands or their favorite TV shows. But with four SKM 2000s with 965 capsules on stage, and over a dozen acts getting to use them, it was all the buzz. “Everyone was talking about that microphone like it was the latest hit single!” he laughs.

Much of the rest of the stage benefitted from Sennheiser wired and wireless technology. Everyone, except the drummer, used Sennheiser ew 300 IEM G3. For his signature drum sound, Whitt used Sennheiser e 901, e 902, and e 904 for close mic’ing and Sennheiser MKH 8040 cardioid condensers for overheads. “I used to mix-and-match my drum mics,” explains Whitt. “But ever since I went with the full Sennheiser package, everything sits together better. The mics are complementary in a way that makes the whole system work together with minimal tweaking.”

Whitt and his business partner, Chris Green, frequently recommend Sennheiser microphones and RF technology on OwnTheMix.com. “I always feel that Sennheiser mics and RF technology offer a lot of professionalism at a semi-pro price,” adds Witt. “The sound quality is excellent and the RF reliability is unmatched.”

Shure Supports Proposed Whitespace Database Legislation

The President and CEO of Shure Incorporated, Sandy LaMantia, today expressed the Company’s strong support for legislation recently introduced by Representative Bobby Rush (D-IL) that proposes to protect 13 different classes of wireless microphone users from interference that could result from the operation of new devices that the Federal Communications Commission (FCC) has approved for frequencies (known as the “white spaces”) currently occupied by wireless microphone users.

“Shure thanks and applauds Congressman Rush for his very thoughtful and balanced approach to the white spaces issue,” says LaMantia.  “New white space devices and wireless microphone users can certainly coexist in the white spaces if the new FCC policy reflects an appreciation for the different classes of wireless microphone users who deserve protection from interference.”

The Rush legislation, H.R. 4353, would require the FCC to provide access to an electronic database where wireless microphone users will register their frequencies, thereby protecting their operation from interference from signals transmitted from the newly approved white spaces devices.  The 13 classes of wireless microphone users in the Rush bill include amusement parks, arenas, convention centers, educational facilities, fairgrounds, government facilities, houses of worship, lodging facilities, museums, recording studios, restaurants, stadiums, and theaters. 

“Congressman Rush’s bill simply and comprehensively identifies the professional classes of wireless microphone use and calls for their protection from interference by new devices,” adds Mark Brunner, Shure’s Senior Director of Global Brand Management.  “The general public is often unaware how common wireless microphones have become in everyday American life.  This legislation spells it out and calls for continuity.”

Canon KJ22ex7.6B HDgc Multi-purpose Portable Zoom Lens

Canon U.S.A., Inc., a leader in digital imaging, introduces the KJ22ex7.6B, the newest member of its “second-generation” line of cost-effective HDgc portable HD lenses. First introduced in 2006, the HDgc lenses were specifically intended to work with the emerging wave of cost-effective HD camcorders from all major manufacturers that were targeted at HD news-gathering and budget-conscious HD productions. These lens families encompass the 2/3-inch, 1/2-inch, and 1/3-inch HD image format sizes.

“Since Canon’s introduction of our HDgc lens series, we have received enthusiastic feedback from our worldwide community of users,” says Larry Thorpe, national marketing executive, Broadcast and Communications division, Canon U.S.A. “Those end-user experiences have helped guide the design of our second-generation line of cost-effective HDgc portable HD lenses, starting with the KJ17ex7.7B portable 2/3-inch HD zoom lens, which was introduced [in 2009] at NAB. The new KJ22ex7.6B is the second in this 2/3-inch family of lenses. These lenses retain the robust magnesium optomechanical design of our higher-end lenses, as this cannot be compromised in ENG applications. Canon’s mobilization of contemporary design tools and optical materials have facilitated a significant cost reduction, while still maintaining an impressive overall HD imaging performance.”

The Canon KJ22ex7.6B is designed as a multi-purpose telephoto lens. Striking an excellent balance between size, weight, and exceptional optical performance, the lens encompasses a generous range of focal lengths while also providing a modest wide-angle of almost 65 degrees in the 16:9 HD image format. This feature provides camera operators with flexible image-framing options, especially for outdoor shooting. Additional design optimizations include Large Diameter Aspherical lens elements that contribute to a better control of comatic aberration, geometric distortion, and corner resolution. Curvature of field and chromatic aberrations have also been reduced by use of special optical materials that include Fluorite and Hi-UD glasses. Extensive computer optimization of both the optical and optomechanical designs contributed to achieving a high-performing telephoto lens within a compact and lightweight body.

Ease of use and reduced operator fatigue were specific design imperatives of the new Canon KJ22ex7.6B, with particular emphasis on a re-designed Digital Drive unit for greater operator comfort and convenience. The Digital Drive unit enables users to program precise and repeatable settings into the KJ22ex7.6B lens for zoom position and speed, focus, and iris. An information display built into the Digital Drive unit makes precise customization quick and convenient. Users can program as many features as they wish, or, if they prefer, none at all. This new unit was designed to improve the tactile interface for the control of zoom, iris, and focus functions. Improvements include widening the spacing between the focus ring and the Digital Drive unit so operators are less likely to accidentally change settings while manipulating the focus control. Of particular importance, Canon incorporated a new software platform within the Digital Drive unit that allows the KJ22ex7.6B to work with the different chromatic aberration correction systems developed by various camera manufacturers.
