Taking its place among Central America’s architectural wonders, the Casa de Dios church is the culmination of years of planning and fundraising that has given Pastor Cash Luna sanctuary space for a congregation of more than 12,000, as well as satellite youth churches supplementing the main building.

Casa de Dios churchThe chosen partner for A/V and lighting installation, Michael Garrison Associates was involved from the early stages of the project, working with the architect to adapt the design to accommodate a technical system that would meet all of the church’s required. ‘Because of the size of the sanctuary, we initially specified a line array,’ Garrison explains. ‘However, half way into the project we learned that they wanted to zone the seating to accommodate groups that were far less than 12,000. As a result, 

A long-time user of Tannoy systems, Garrison had the company’s loudspeaker technology in mind from the outset: ‘Initially, we looked at Tannoy and a couple of other brands,’ he confirms. ‘When we modelled all of it, we were very surprised to find that, in the computer modelling, the Tannoy VQ system – an exploded cluster for the main and two delay rings of satellite delay speakers - actually exceeded the max sound level of the very fine line array system, and with much smoother coverage.’we ended up starting from scratch on a new system design.’

With integrated digital signal processing, network control and dual channel class-D amplification, the VQNet line is a self-powered, networked variant of the company’s flagship VQ Series high -performance, high SPL sound reinforcement system.

With Pastor Cash Luna having the final say on the project, MGA shared the modelling data with him: ‘When we showed the coverage to the pastor and the cost comparison, his mind was made up,’ says Garrison. ‘Using VQ instead of a line array saved this project something in the realm of US$500,000. When he heard that, the pastor said: “I don’t care about the touring riders. If they want to play here, they will play with my system”.’

With assistance from Graham Hendry, VP of TC Group’s Applications Engineering and Support division, the team at MGA designed and installed a system that is unique to the space, but one that also considers aspects such as line of sight and aesthetics as well as the general acoustics. The system design included one main exploded array flown above the stage consisting of five VQ60 loudspeakers. With such a defined pattern control, the VQ60 make the horizontal coverage seamless; as a point source the vertical dispersion is perfectly consistent and not hampered by vertical inconsistencies inherent with line arrays, especially at high frequencies.

‘There are two further delay rows of VQ60s, which allow zoning to accommodate smaller congregations,’ says MGA Senior A/V Designer, Steve Shewlakow. ‘There’s also a main LF array of 18 VNet 218DRs and nine of the VNet 215HLs, and then a supplemental five-position delay zone with three VNet 218DRs in each zone in a cardioid array. There are also two subs on the ground that act as warmers and front fills.’

One of the most interesting and unique aspects of the installation is the central subwoofer cluster that sits directly in the middle of two large video screens, described by one onlooker as ‘hiding in plain sight’.

‘People in Latin America they like a lot of bass, so we knew from the beginning that we couldn’t use the usual US reference points for that,’ Garrison says. ‘We knew we would have to put in a low frequency and subwoofer system that would go beyond what would be expected in the US.’

‘With the help of Tannoy, Graham Hendry and other people, we came up with a three wide array that is nine boxes tall, so a total of 27 boxes, 218s on the outside and the centre is 215 boxes, for the main LF subwoofer array, and then we have some supplemental units at floor level because people want to be able to feel that additional sub to reach the outside edge,’ he adds. ‘Because the room is so deep and because they wanted to be able to zone it, we also have an additional delay ring with five positions, with three double 18s each. It comes to around 42 subwoofer devices in the room, and it’s pretty amazing. Working with signal timing, we were able to achieve wide dispersion, and it’s a pretty wide fan room.’

That overall performance characteristic of the VQ system impressed everyone involved: ‘It’s punchy, it’s concert levels, it’s thump your chest kind of levels, so we’re very happy with it,’ Garrison reports. ‘More importantly the pastor is happy with it, and the sound people are very happy with it.’


Two eminent colleges in Trondheim have turned to IT and A/V specialist Atea to set up systems for lecture hall audio and online content streaming in classrooms – and found Symetrix Solus and Radius processors central to their solutions.

NTNUIn both cases, the processors are part of systems that include large numbers of RCF and Focal speakers, and Sennheiser wireless and Audix wired mics. Cisco and Tandberg collaboration equipment, Crestron control solutions, Sony and Epson projectors and Samsung screens are among the other stalwart elements of the installations.

With offices throughout Scandinavia and Eastern Europe, Atea is a prominent player in IT and A/V installation. During the past 12 months, the company has found increasing applications for Symetrix’ SymNet Solus 16 open architecture standalone DSP and SymNet Radius 12x8 open architecture scalable DSP with support for Audinate’s Dante media networking technology.

‘Generally speaking, these offer the processing power and versatility required for academic-type installations,’ says A/V Senior Consultant/Programmer, André Dominic Schorr. ‘In most cases, we are talking about general purpose lecture room audio, streaming and sharing of content, and flexible routing to and from different lecture halls and teaching spaces. The Radius 12x8 and Solus 16 are entirely capable of handling such tasks, but there is no doubt that Dante networking affords even greater flexibility, so the level of interest in those solutions is definitely on the rise.’

NTNUIn the most recent phase of work at its two primary academic clients in Trondheim, Schorr and his team have installed multiple 16-input/8-output Solus processors.

‘One of the really great aspects for this type of project is that with Solus you have a library of design templates that provides a solid basis for most problems encountered in typical university installations,’ he explains.

‘I come from a live sound background, and it seems to me that Solus’ design makes life straightforward for all types of engineers – it is very easy to get to grips with.’ Then there is the processor’s rock-solid reliability: ‘I have never experienced a system failure, which is precisely what you need when dealing with high-volume projects like these.

‘In our current and next phase of work, we are upgrading some auditoria and lecture halls that have not received significant attention for as long as ten or 15 years,’ he adds. ‘With the Symetrix DSPs we are confident that we have the tool to take these rooms forward confidently into a new era of technological ease and versatility.’

Hart House’s Great Hall‘We have one of the most diverse clientele, with a massive variety of events,’ says A/V Manager Ira Cohen of the University of Toronto’s Hart House – one of the largest and busiest event spaces in Canada. Hosting around 7,000 annual events, including conferences, concerts, corporate and social events, Cohen recently designed and oversaw a new audio installation for the Hart House’s Great Hall, the signature space at the venue.

Cohen’s design uses a Soundcraft Si Expression 1 to control the system, which includes BSS Blu-80 signal processing with a CobraNet expansion card for full Harman integration with the console. Cat5 connections are used to patch the console to control the entire equipment rack.

‘Together with the CobraNet expansion card, this one-of-a-kind system offers an incredible amount of flexibility with the ability to run any type of event or show imaginable,’ he says. ‘Factoring in the expansion capabilities, it is a system that Hart House has longed for and one that we are truly proud of.

‘I have long held Soundcraft in high regard, and over the years I have had the pleasure of mixing on various analog and digital boards and have always trusted the level of sonic quality and control you get with Soundcraft. At this price point, there is no other board in the market with as many top quality features as the Si Expression. It allowed me to present a proposal design at half the cost that external companies offered.’

‘The console has exceeded performance expectations,’ according to Cohen. ‘Its ease of use out the gate has been a pleasure to work with – I am mostly impressed with the layout, because it’s quite nice to have the physical controls of your channel strip and dynamics right in front of you. Overall, it is a very economical and straightforward board to operate, which is great for new users. All the advantages of digital are literally at your fingertips, rather than through page layers.’

Alongside Georgia’s Stone Mountain Park’s natural glory, crowds regularly come to see the laser, firework, pyrotechnic and projection show that has operated on summer evenings since 1983. Additionally, there is the Geyser Towers playground, Sky Hike family ropes adventure course, a children’s activity area and the Crossroads Base Camp with restaurants, retail stores, a movie theatre, mini-golf and craft stores. Less spectacular but equally impressive is the Full Spectrum audio installation, which is based around a Symetrix SymNet Edge Dante networked audio DSP system.

Stone Mountain Park‘The owners built Crossroads about a decade ago, and the original sound system did a passable job of supplying background music,’ explains Full Spectrum partner, Paul Creasy. ‘But as the development grew and several of the establishments set their sights on more and different events, the constraints of the original system became apparent.

‘The upshot was that they needed something that was completely flexible. Moreover, the owners wanted to expand system coverage to several of the other attractions, but they didn’t want to have to start from scratch every time they expanded. The Symetrix SymNet Edge DSP system offers the perfect solution. Each Edge frame has modular I/O, and its open architecture programming allows us to customise system features and performance. The fact that the Edge DSP system networks via Dante will allow us to easily expand across the park.’

The network will grow and eventually take in all of the park’s attractions via an inexpensive Cat5 network. Currently, eight SymNet Edge frames populate Crossroads, each in a different building.

‘We do niche A/V,’ Creasy says. ‘You can’t call up a preset for a place like Stone Mountain Park. I appreciate the flexibility and intuitive layout of SymNet Composer open architecture software. It’s easy to work with, even with a complex system like this one. Moreover, any time I have a question, Symetrix’ tech support is available and ready with an answer.’

Within the coming year, Full Spectrum plans to expand the sound reinforcement system via Dante and additional remote Edge DSP units to incorporate the Plantation, the Sky Ride cable car complex and Stone Mountain’s famous laser show.

Flare AudioBritish loudspeaker technology company Flare Audio Limited has appointed UK pro audio supplier Orbital Sound as its exclusive distributor for the UK and Ireland markets.

‘Our two companies have complementary backgrounds – live touring, entertainment installations, studios and events – making for an extremely powerful combination,’ says Flare Audio MD, Kristin Hanson. ‘At Flare Audio, we are introducing what is essentially a new approach to sound reinforcement, making the choice of our first major distributor absolutely key. We were looking for a company that would embrace new ideas and relish the prospect of bringing real innovation to the marketplace, while always putting the customer first. Orbital Sound has an outstanding reputation on all counts, and represents the ideal match for us.’

Orbital Sound will be focusing on introducing Flare Audio’s innovative product range to a broad audience in coming months.

‘Flare Audio’s innovative R&D approach has created a range that delivers high-definition audio with exceptional vocal clarity,’ says Orbital Sales Director, Tom Byrne. ‘This is combined with an extremely accurate sonic footprint that is present in every Flare Audio design – from the studio monitors to large-scale stadium line arrays. This unique blend is something that excites us from a distribution perspective.

‘We will be working initially on establishing a network of nationwide partner dealers that match our standards for sales, installation, service and support excellence. We have a broad canvas to work on – with products that deliver outstanding performance whatever the application, across the live entertainment market, commercial venues, A/V, houses of worship, studios, festivals and touring. We will also be putting in place the very best of training and application support, combined with building market awareness. Our two companies have very similar mindsets and a dedication to technical excellence – we are looking forward to a successful partnership.’


Unhappy with the poor standard of audio that is typical of public spaces, Unibail-Rodamco wanted to create something better for the Aéroville retail centre.

AérovilleLocated adjacent to the Paris Charles de Gaulle Airport (CDG), Europe’s largest listed commercial property company planned different playback content for the various areas, requiring 30 input sources and 40 different outputs feeding more than 250 loudspeakers (without parking areas). Merging Technologies’ Ovation provided the means.

The company to visualise, design and implement the ambitious system was hého, a company well versed in sound architecture and design having developed a new approach to sound in shopping malls and large public areas. hého took the sound concept proposed by Unibail-Rodamco, and saw the project through all steps in the process except installation.

Exploiting and improving the concept of Sound Paths, the hého team knew what they wanted to create, but a year ago they were still struggling to find a solution that would do this efficiently. Word of Ovation took Laurent Sauvagnac and David Guérin to the Merging stand at ISE 2013 – impressed by the demo and the discussion that followed, the design concept seemed to be achievable and the planning began in earnest.

AérovilleThe size of the project was daunting – 84,000m² of retail, 200 shops, 30 restaurants, an Auchan hypermarket occupying 15,000m², a 12-theatre multiplex cinema from Luc Besson’s Europacourt, 4,700 parking spaces and a budget of €355m. The plan was to provide a world-class shopping centre for the 120,000 people working in the area and the 60m passengers arriving at CDG every year. Unusual in being all on one level, the design focused on five different and unique landscapes. Different materials and appearances appealed to sight, smell and touch… but what about sound?

The Bali Market, Africa Lodge, Nordic Chic and Tokyo Mix are all distinct areas of the shopping centre that provide a variety of retail themes. And, Terminal Cook provides a fifth scene with a tropical atmosphere for the Dining Experience (taste) that includes a play-alone piano. With all these varied areas, there was plenty of scope for a variety of soundscapes to feed the last of these senses. By programming scene specific atmospheres and identities, and then being able to program a randomised playback, routing and gains throughout the day allowed each district’s sonic persona to remain interesting and engaging at all times.

This mall is open seven days a week and the audio programme is required to run for 14 hours per day so reliability and stability are obviously paramount. Networked audio provides the flexibility and simplicity needed to control the 40 separate loudspeaker zones. The Ovation connects to a Symetrix SymNet Radius 12 x 8 which then connects to the new Bose PowerMatch PM8500N power amplifiers via Dante.

‘Ovation is very easy to use – you don’t need advanced programming skills to set up interaction rules between events to create even the most complex show,’ says hého Technical Manager, Julien Bachelier. ‘It is a powerful tool with many functions and controls and it suits this application extremely well.’

One of the prizes of the New York Hamptons dining scene, Dockers Waterside made do with a below par sound system until recently – in spite of offering regular live music, as well as its two outdoor ‘living rooms’, three bars, and tables that overlook the bay. Now, however, Taylor Sound has stepped in with a system built around a Symetrix Zone Mix 761 fixed-architecture processor, bringing improved sound quality and control from smartphones via Symetrix’s ARC-Web.

Dockers Waterside‘Dockers Waterside previously had some amplifiers and music-store-grade analogue and digital processors,’ says Taylor Sound owner, Bill Taylor. ‘Some of the components had gone bad, but the real motivation for upgrading the system was the owner’s inability to manage the inconsistent levels coming out of his music players. His solution was to try to compress the signal so as to achieve uniform output, but the compression sucked the life out of the music and killed the low end. It just didn’t sound good.’

The automatic gain control (AGC) in the Symetrix Zone Mix 761, together with the rest of its processing power, is providing rather better results.

Inputs to the 12-input Zone Mix 761 include an iPod, a Sonos music player system, output from the live music system and a wireless microphone. Taylor used all six of its outputs to feed six separate zones around the venue via three new Crown XLS 1000 amplifiers and the existing loudspeakers. Additional improvements include a collection of Audio-Technica paddle antennas that provide coverage for the wireless microphone throughout the establishment. The staff select zone inputs and adjust volumes via Symetrix ARC-Web, which they access from smartphones. They can also make changes using a hardwired Symetrix ARC-2e wall-mounted, menu-driven remote located near the main bar.

‘We got the system up and dialled in very quickly,’ Taylor says ‘We were able to give Dockers so much more functionality than it had previously. Symetrix’s AGC algorithm is great, and the owner is very pleased with the quality and consistency of the sound now. Being able to hand him ARC-Web put the installation over the edge. He loves having that kind of convenient, cutting-edge control.’

Recently reopened after a complete interior renovation, the 685-seat Baldwin Auditorium on the campus of Duke University in Durham, NC has installed a Meyer Sound Mina line array loudspeaker system.

Baldwin Auditorium‘We’d designed the physical acoustics to be quite live, so we needed line arrays to focus sound on the audience and not excite the architecture,’ explains Ben Bausher, Senior Consultant at Jaffe Holden, who designed the hall’s acoustics and reinforcement. ‘We also wanted a minimal profile for aesthetic reasons. Finally, a self-powered solution was mandatory, as there was simply no place to put amp racks, much less a cooled equipment room. Mina was a perfect fit on all counts.’

The system comprises main LR arrays of ten Mina loudspeakers each, supplemented by ten UP-4XP 48 V loudspeakers for front fill, two MM-4XP self-powered loudspeakers for side-balcony coverage and two UPJ-1P VariO loudspeakers for over-balcony coverage. Four 500-HP subwoofers are recessed under the stage for vibration isolation and a Galileo loudspeaker management system with both a Galileo 616 and a Galileo 616 AES processor provides system drive and optimisation.

The system was installed by Audio & Light: ‘As self-powered technology eliminates the need for an amplifier room, the Mina system was more cost-effective as well,’ says Brian Cox, VP of Sales at Audio & Light’s Installation Division.

‘The system coverage is exceptionally uniform,’ says Richard Kless, Assistant Manager of Theatre Operations for Duke University. ‘What we had before was really a glorified rehearsal space, and now it’s a splendid-sounding and aesthetically gorgeous concert hall. It was an amazing transformation.’

The new system works with the room’s acoustics for performances of classical, jazz, world music and other music. These concerts are presented by the school’s own music department and Duke Performances, which sponsors touring professional artists.

The Baldwin Auditorium renovation project was designed and supervised by New York-based Pfeiffer Partners Architects in consultation with Ray Walker, Duke campus architect. Principal acousticians for Jaffe Holden were Mark Holden and Matthew Nichols.

The Czech Republic’s Brno University of Technology has established itself as one of the country’s leading universities, and recently sought to consolidate this position with a new technical installation. Covering 12 lecture halls, with capacities ranging from 75 to 200 seats, along with smaller lecture rooms, the centrepiece of the project – and its most challenging in acoustical terms – is a 300-capacity sperical auditorium.

Brno University of Technology‘The volume and acoustics of the room are everything but standard, and yet perfect coverage and intelligibility had to be achieved,’ says Michal Zeman of Audio Digital who, along with systems integrator APS, provided the Faculty of Electrical Engineering & Communications’ new installation. Zeman was aware that a system based around Symetrix SymNet Edge DSP technology could achieve the desitred results.

The modular SymNet Edge provides a 48-channel digital audio matrix and the ability to scale up its capacity should the need arise. Consisting of three Edge units located around the auditorium and connected over a standard Ethernet network using an Audinate Dante bus, Edge’s decentralised structure allowed Audio Digital and APS to keep analogue cable runs at in the auditorium to a minimum.

The Symetrix DSP – which is integrated into the auditorium’s Cue control system – is also kind to the teaching staff, who do not necessarily have great systems operation experience. ‘The choice of Symetrix really paid off here, too, as on one hand it offers user-friendly features such as automixing, and on the other allows external access to every single parameter needed, so there were no limits in adjusting the Cue’s user interface to the needs of the users,’ says Zeman.

Carefully fine-tuning the Symetrix system to optimise the acoustics, Zeman and collaborators used AFMG’s Ease software to derive a loudspeaker design based around TOA line arrays and Dynacord subwoofers. Amplification comes from APart Audio amplifiers, while wired and wireless microphones by TOA, Electro-Voice and MiPro complete the core specification.

The project’s use of Symetrix technology is not restricted to the main auditorium, however, as two of the other lecture rooms feature SymNet Solus 16 standalone DSP units, while audio in ten smaller spaces is driven by Zone Mix 761 devices.

Paying tribute to the ‘feature-richness and competitive price level’ of the Symetrix DSP technology, Zeman says that it was ‘from the very beginning our first and only choice for the DSP brain. No other brand I have encountered currently comes even close to what Symetrix can offer.’

Le 1700While not readily associated with skiing, the highest mountains in the Middle East are to be found in Lebanon along with several fully equipped resorts that have been in operation since the 1960s. The recent refurbishment of Le 1700, one of the best après-ski restaurants in the resort of Faqra, has seen the installation of a QSC sound system by Beirut-based distributor, Techno Sound.

Addressing both the dining and live music requirements of the French restaurant, Techno Sound fitted six QSC K10 speakers, two K12s, six KW122s and five KW181 subs over the course of two days. The installation was ready for the 2013 skiing season.

‘We were asked to provide some speakers for a live test as part of the complete refurbishment of the restaurant,’ explains Pierre Fahed of Techno Sound. ‘The PA had to be suitable for the playback of recorded lounge music suitable for quiet dining, but also for the amplification of live music for dancing. The management tested several brands, but they chose the QSC K and KW Series after our President, Georges Bitar, showed them what the speakers could do on site.

‘The guys at Le 1700 have been very pleased with their choice,’ Fahed reports. ‘I think the sound quality of the QSC speakers won them over; they liked how the speakers sounded when running quiet and loud, and they liked our reputation for good after-sales support — which we offer even for clients halfway up a mountain.’
