Alexandria First Presbyterian ChurchSet among the first lands to be settled by European colonists, Alexandria First Presbyterian Church boasts a main sanctuary built in the late 1800s, and listed on the US National Registry of Historic Places. But despite being one of the area’s older buildings, the church is very modern inside – thanks to a sophisticated A/V system designed and installed by JD Sound & Video.

The system includes distributed HD video, with multiple screens throughout, as well as a sound system featuring Community Professional Loudspeakers’ Entasys column arrays and VLF Series subwoofers. ‘It’s not a large building, and it’s not very ornate,’ says JD Sound’s Joe DiSabatino. ‘But they’ve invested wisely with the technology they’ve installed.’

Typically, the interior of the sanctuary is highly reverberant, and achieving good spoken word intelligibility has long been a challenge: ‘It’s a large, boxy room with high ceilings, hard plaster walls, and lots of hard wood,’ says DiSabatino. ‘It sounds great for the choir, but not for the sermon.’

JD Sound recommended a pair of Community Entasys column loudspeakers to cover the entire space: ‘We set up a temporary system for them to use during a service, and they were immediately convinced,’ says DiSabatino.

EntasysThe church services make good use of music, and DiSabatino recommended a pair of VLF208 subwoofers to fill out the frequency range: ‘We built the subs into the altar, underneath the stage,’ he says. ‘They provide just that little bit of extra low end and kick.’

The Entasys also addressed the church’s aesthetic concerns: ‘The columns are painted to match the walls, and are barely visible,’ says DiSabatino. Crown amplifiers power the system, and a Rane HAL system provides DSP and enables the church to make multi-channel recordings of their services, with an eye toward webcasting in the future.

The installation of the new system has allowed the church to repurpose its previous loudspeakers – a pair of Community CSX cabinets: ‘The kids have a gathering spot down in the basement, and the original system is still working fine, so it was perfect for that,’ says DiSabatino.

‘The Entasys system was the perfect solution,’ DiSabatino concludes. ‘Coverage is consistent to every seat, even under the balcony, and we’ve got far more gain before feedback. And they sound terrific.’

Indiana’s Church of the Greater Faith is a forward-looking Pentecostal congregation whose contemporary approach to worship has seen it growing consistently – a source of both joy and challenge, and as the modest 700-seat sanctuary now hosts two Sunday morning services, with a third service added in the afternoon.

Church of the Greater FaithDespite efforts to improve the problematic acoustic of the room’s peaked, metal A-frame structure over the years, the resukts have actually made things worse: ‘The original system was poorly designed and underpowered to begin with, and they spent the next 11 years trying to fix it,’ says Jason Ryder, General Manager of Lake Charles, LA-based Porche Advance Systems. ‘The result was a patchwork of mis-wired, out-of-phase components, and a room with dead spots and poor, uneven coverage.’

‘They knew they ultimately needed to replace the entire system, but they had been reluctant to do so because they were looking at moving to a larger venue within the next couple of years,’ offers Porche Advance Systems owner, Jacob Porche.

The solution to the problem has come in the form of a Renkus-Heinz Varla loudspeaker system – one of the first Varia systems to be installed in the US.

‘With Varia, we were able to design an expandable, flexible system that would work for them now, and become part of their new system later,’ Porche explains. ‘When they build the new sanctuary, these three cabinets will become the bottom three cabinets in a larger, eight-cabinet array. The fact that this was an investment that could grow with them was a huge plus.’

The Varla system comprises LR arrays of three Varia cabinets each: ‘The top box has a 90° by 7° horn pattern, the middle cabinet has the transitional horn that goes from 90° to 120° wide by 15° vertical, and the bottom unit covers 22° vertical by 120° wide,’ Porche says. ‘That tapered approach enabled us to cover the entire space without resorting to EQ and processing, and to achieve a remarkably flat response from left to right. There is not a single dead spot in the entire sanctuary now.’

Ryder believes that the congregation’s response to the new system has been unconditionall good: ‘They were all singing louder and moving with the music – the energy level in the room is fantastic.’

‘One of the church’s board members came up to me after a service to thank me,’ adds Porche. ‘He said it was the first time he’d ever been able to hear every word of the sermon, and every instrument in the band.’

‘With Varia, Renkus-Heinz has developed a system that can truly adapt to any environment,’ Porche concludes. ‘The system’s variable coverage means it can work in any room, and its modular, expandable design means that it will not become obsolete once the church moves to larger quarters.’

Specialist systems integrator Abas (Automation Broadcasting Audio Security) has installed new loudspeaker systems for the play and spectator areas of the outdoor and indoor tennis courts at the exclusive Tatoï Club.

Tatoï ClubA short drive northeast of Athens, the club is regarded as one of the best tennis academies in Greece, and provides for the well-being of members with spa, beauty, swimming, physiotherapy and nutrition centres. The complex also houses indoor and outdoor restaurants, meeting and conference rooms.

All of the Tatoï Club tennis courts adhere to strict international guidelines for hosting tournaments of all sizes and levels, offering the best in training methods and amenities. Emphasis is given to on-court training and complete training support, which includes nutritional monitoring, regular ergometric exams as well as physiotherapy and medical support.

Athens-based Abas designed the club’s audio systems around Ateïs network processors for compliance with EN-60849 standards. For the 18 tennis courts, Abas chose Community’s two-way, horn-loaded, coaxial R.25 loudspeakers to meet the requirements for intelligibility and well-defined dispersion. The loudspeakers were additionally required to meet the all-weather needs of the application. Abas installed Monacor amplifiers to drive the Community loudspeakers.

‘The Community R.25 stood out as the best solution for audio quality and intelligibility,’ says Kostas Drosos from Abas. ‘The system is mainly used for speech messages and music distribution and the main tennis courts are addressed individually, so pattern control was very important to minimise spill to adjacent courts.

‘The R.25 is very compact and its availability in black made it aesthetically ideal for mounting on the black lighting poles of the courts. The R.25’s extreme all-weather resistance and long-term reliability will also ensure the system will remain looking and sounding good.’

Specialising musical productions, Teatr Rozrywki, in the Silesian city of Chorzów, has recently completed an extensive renovation, and at the end of 2012 completed the modernisation of its audio infrastructure.

Teatr RozrywkiCommencing with the smaller 100-capacity auditorium, the project moved on to the main 577-seat space. The main challenge facing Piotr Kozłowski and Wojciech Grządziel from system integrator, Pracownia Akustyczna, was to provide independent gain control from the FOH and monitor positions.

One of Poland’s leading design consultants, Pracownia Akustyczna has been responsible for all acoustical and electro-acoustical modernisation of the venue in the last few years: ‘We have been using digital audio networks in our designs for almost ten years,’ says Kozłowski. ‘Many systems today use much more digital kit than analogue, so it is natural to want to use some kind of digital cable to glue all this signal jungle together.’

The chosen solution was an Optocore X6R-DualMic topology, and so the system design was based on three X6R-FX-DualMic and nine X6R-TP-DualMic, providing 96 mic connections with independent gain control for each channel. In addition, two X6R-TP-16LO interfaces were pinstalled as return devices from the consoles – with all X6R units located in the stage rack.

For the FOH position, the theatre commissioned two Yamaha M7CL-48 desks equipped with Optocore YG2 and YS2 I/O cards to allow direct connection to the Optocore network (the same card combination is used with the M7CL-48 down at the stage end). As a result, all three Yamaha consoles are able to control the Optocore preamps using the German manufacturer’s Yamaha Emulation Mode. The two FOH consoles control the primary channels 1-96, while the monitor console operates selected secondary channels 1-48 or 49-96 – giving the respective sound engineers the unique ability to control the gain independently.

The third section of the system is installed in the amp room, where two Yamaha DME64N processors, fitted with YG2 cards, provide feeds to the L-Acoustics amplifiers, with a further Optocore DD2FR-FX Madi interface enabling the Madi connections.

Lukasz Tobola, technical director of Polish distributor, M.Ostrowski Sp.j, supplied all the Optocore equipment and is satisfied with the solution: ‘Optocore is one of our leading brands and well known in Poland,’ he says, at the same time confirming that this is the biggest Optocore system installed in the country to date.

‘It is a perfect solution for any system – whether large or small – as this flexible, scalable and elegant solution fits almost any application. The core requirement here was to switch to the digital domain, offering the same or better functionality than a traditional analogue theatre system, with a mic splitter.

‘Optocore was the only solution that offered independent gain control of the real analogue preamps, without any digital tricks. The DualMic device is simply brilliant and will certainly become our best-seller in the Polish market.’

One of the highest appellate courts in China, the Higher People’s Court of Guangdong Province typically sits in judgement over disputes in excess of RMB300m. As well as Chinese cases, the court presides over cases from Hong Kong, Taiwan and Macau – most famously the Apple and Shenzhen Proview iPad trademark dispute.

Higher People’s Court of Guangdong ProvinceThis is not a setting where misunderstanding through the inaudibility of those speaking is acceptable: ‘When the authorities determined the court’s PA system required renovation they set higher definition and intelligibility as immutable goals,’ says Long Po of system integrator, Acejet (Group) Technology, the company called in to manage the project.

As the floor and walls of the courtroom are marble clad, the reverberation is high. Multiple gooseneck microphones with high input gain invite feedback, and in deference to the importance of the cases heard here an extremely discrete audio system was required.

‘One that could deliver high SPLs,’ Long Po qualifies. ‘Fortunately, we have more than ten years’ experience using the d&b audiotechnik product range in prestige installations such as Nanjing University Theatre and the Headquarters of the China Development Bank. We are accustomed to dealing with the more difficult acoustic environments such venues can present.

‘The sheer variety of systems available from d&b, all with consistent quality performance and remarkably accurate pattern control, gives us a toolbox with which to address any problem,’ he continues. ‘We contacted William Xue at d&b China’s head office and arranged for the court room to be Ease modelled. Then, in consultation with Mr Xue, determined a system design using elements of the d&b E-Series – E12 and E15X-Sub for main left and right and a number of 8S loudspeakers from the d&b White installation range that are embedded in the walls of the audience area for local fill without exciting the fragile reverberation environment.’

The installation is powered by d&b D6 amplifiers throughout.

The University of Hawaii’s Translational Health Science Simulation Center (THSSC) is a specialised facilied that presents its students with real-life simulations of scenarios they will meet in the field. Aiding its instructors is a newtork of more than 100 Tannoy CMS 801DC in-ceiling loudspeakers have been installed throughout the facility.

THSSC‘They’re everywhere – hallways, the lobby, the exam rooms, in three conference rooms equipped with video/teleconferencing systems and in the main simulation area, the Multimedia Room…’ says says Alex Donkle, of DL Adams Associates, the firm responsible for designing centre’s A/V and control systems.

One of the most important functions the audio system serves is to provide students and instructors with a means to interact effectively during simulations. ‘THSSC has a variety of mock exam and surgery rooms where students get feedback from the instructors while interacting with their ‘patients’; intelligent mannequins the instructors control,’ Donkle explains. ‘There are speakers, microphones and cameras in the rooms so the instructors can monitor student’s work and so the students and instructors can communicate with each other.’

The system also allows instructors to film and record student interactions for subsequent analysis. Additionally, it features a series of Crestron touchpanels for users to control various parameters such as signal routing, and small speakers mounted in the mouths of the intelligent mannequins to provide additional realism.

The choice of the CMS Series – premium range of full-bandwidth high-power ceiling-mounted loudspeakers – was based on DL Adams’ previous experience with Tannoy: ‘Basically, they provided the easiest way for us to supply a high-quality experience and realistic sound for all of these uses.’

That’s particularly important in the Multimedia Room, which is also equipped with two Tannoy CMS 110TB subs and boasts a sophisticated A/V system designed to recreate the experience of responding to a given patient’s needs in a variety of locations and situations as realistically as possible.

‘Having uniform, high-quality sound and no hotspots was very important. We found that the Tannoy provided the most even spread and uniform sound quality,’ Donkle explains. ‘When students are moving around they’re not walking in and out of the sweet spot constantly as they would with some other speakers. Tannoy are just very consistent in these types of spaces.’

Founded in 1979, DL Adams Associates is a multi-disciplined engineering firm that provides consulting and design services in acoustics, performing arts, presentation and information technology and telecommunications systems.

Opening a new theatre put considerable pressure on a UK college to maintain the high expectations of both students and staff. The St Lawrence College in Ramsgate prides itself on its facilities, bringing the multi-use theatre as part of a new-build that includes classroom space, a new boardroom and dormitories.

RSG M300 and S1608Able to seat all 480 senior school pupils, the new hall has a balcony with a stage dominating the back wall but can be adapted to hold performances in the round. An open brief for the design of a suitable audio, video and lighting installation was extended to the London office of Stage Electrics, where Business Development Manager Mark Larcombe responded with a system design placing a Roland M-300 at its centre.

The requirements for the project were typical school requirements – ease of use for the variety of people who would need to use the products, flexibility of the system to be used for different purposes and within a specified budget. The various uses of the theatre would be from school assemblies and prizegiving, to GCSE student productions, up to major productions.

As part of the V-Mixing System, the 32-channel console connects via Cat5e to Roland Digital Snake products for simple and high quality audio transmission, distribution, splits and merging. At St Lawrence College, the M-300 can adapt easily to set-ups ranging from using just one microphone to a complicated live band.

Stage Electrics chose the Roland M-300 Digital Mixing Console, the Roland S-1608 Digital Snake Stage Unit and the Roland S-0808 8 x 8 I/O unit connected with REAC (Roland Ethernet Audio Communication) to provide a ‘plug-and-play’ digital system.

Using REAC and Cat5e cables for the audio transmission proved simple and cost-effective as a number of Cat5e points were installed around the new venue. The S-0808 is installed in the back of a control rack and connected to the amplifiers, while the S-1608 has been left as a portable unit so that it can be plugged into various Cat5e panels around the theatre as required – REAC connectivity allows the use the Cat5e points around the venue to connect to the mixer instead of having to use XLRs from the mixer. If the M-300 is in the control room, connecting by XLR is possible but for more advanced set-ups – for example, where there are a number of musical instruments, then the portable S-1608 can be added where necessary to create more inputs.

‘The M-300 desk with the Digital Snakes provides a straightforward solution, which can be easily added to in the future,’ says Larcombe. ‘The theatre itself is such a high quality venue and the technology so accessible that it is now being used for all purposes, far more than it was originally intended for.’

Named after the singer’s 2003 hit ‘I Love This Bar’, Toby Keith’s I Love This Bar & Grill is a new chain of performance venues being opened in the US by the country music star.

Toby Keith’s I Love This Bar & GrillThe success of the chain’s early locations, the rider-friendly Midas Pro2 as its console of choice.

‘The first Pro2 we installed was in the Dallas location – it was the third Pro2 shipped in the US,’ says Josh Maichele, President of LiveSpace, the company handling the sound installation for the venues. ‘The price point of the console for the amount of versatility, usability and sound quality we get out of it has been a big home run for us.’

LiveSpace was called in to create give the venues both quality and consistency of sound:‘We’re a relationship-based company; we work hard to understand the needs of our clients so that we can tailor a solution specifically for them,’ Maichele says. ‘The important factors for the Toby Keith’s chain revolved around great sound, rider friendliness, versatility and ease of operation. Believe me, we looked at everything on the market, but when the Pro2 was announced, the only real question was delivery date. For how it sounds and what it can do, at that price point, it’s not even close.’

The venues range in capacity from 800 seats up to 3,000 at major locations. Live performances feature both local artists and touring acts. With new locations opening in over a dozen cities in the coming year, another critical factor for LiveSpace is training the house engineer at each location prior to opening.

‘Each location has a house engineer on staff, which is really important when working with visiting engineers who aren’t familiar with the console,’ says Maichele. ‘We’ve developed a workflow for them that makes things pretty user-friendly, with all the routing they should need, plus clearly labeled channel names and a colour-coded system so that engineers can easily understand what they’re running and quickly adjust things like gain and EQ.

‘The biggest problem in working with an unfamiliar console, especially a digital desk, is a fear of getting lost, especially when something starts to ring or feed back,’ he continues. ‘What we’re really teaching is muscle memory, so they have the confidence of knowing they’re only one or two moves away from getting where they need to go. That’s why the POPulation Groups are easily my favorite part of the console. If I’ve built my POP Groups correctly, I can hit those and with one trigger and instantly know where I am.’

To help develop confidence and understanding, LiveSpace walks engineers through the console set up step by step. ‘As we do that, we save those points as scenes so they can see the progression of how we build a show. Those scenes act as a great tool for success. The house engineer can go back through the scenes to see how we did things, and in what order. Another important aspect of training we provide is that we explain the patching, which is very powerful in the Midas system. One thing we love is the ability to hover over an input and see the signal coming in and where it’s routed to from there. That’s very instructive, and a great aspect of the user interface design.’

The last thing that happens before the LiveSpace team turns over the controls is a technical training night, complete with a live band. Maichele explains: ‘We take them from soundcheck right through the show, reiterating the workflow and why it’s that way. We start with a minimum of effects and dynamics, basically to drive home how good this console can sound. Then we build from there. It’s been a very successful approach for us.’

‘Trying to ensure great sound quality while avoiding technical issues across a national chain is a challenge,’ Maichele conclude. ‘Our whole approach to A/V systems is to simplify life for everyone who engages with our work, and the Pro2 definitely fits that profile of sophisticated technology that’s easy to teach and easy to use. It’s everything we wanted in a console, from the rider friendliness right down to the price point.’

One of Latin America’s most versatile and comprehensive exhibition and convention centres, Sao Paulo’s Expo Center Norte hosts events ranging from trade shows and conventions to corporate bookings. Requiring an upgrade of its sound system, Roberto Benedito contacted Sao Paulo-based systems integrator Soundvision.

Expo Center NorteThe original sound system installed in 1993 was unintelligible and event attendees could not hear announcements, which was of great concern to the venue’s management: ‘We immediately narrowed the choice for the project down to Community’s R-Series, because of the output, directivity and intelligibility they provide,’ says Antonio Tadeu Torquato, General Director at Soundvision.

To demonstrate the performance of the R-Series, Soundvision installed a single R.5HP loudspeaker in one of the Expo Center Norte’s convention halls, leaving the venue managers extremely impressed with its performance. They promptlycommissioned Soundvision to install the new Community sound system.

The final system design includes 44 Community R.5HPT 12-inch loudspeaker systems. The three-way, coaxial, horn-loaded design of the R.5HP provides the high sensitivity and exceptional mid-range clarity required for the noisy and reverberant environments found in halls like the Expo Center. The light grey loudspeaker enclosures also blend well with the walls and ceiling of the convention center, making the system visually unobtrusive. Fewer loudspeakers were utilized for the new sound system, but the overall coverage and intelligibility was dramatically improved.

The public address system was designed so that announcements can be made from the main control centre, as well as from any of ten zones located throughout the five separate halls that make up the convention centre. The system was also required to be very easy to operate as staff need to be able to make announcements in each of the different zones.

The Community loudspeakers are powered by Crown CTs 4200 amplifiers and Soundvision opted for Harman Professional’s IDX control system. ‘Roberto Benedito and the management of Expo Center Norte are extremely pleased with the performance of the new sound system, and so are we,’ Antonio Tadeu Torquato notes.
