New Allen & Heath GLD Manages Russian BMW Launch

Russian PA company, City Sound, recently selected Allen & Heath’s new GLD digital mixing system to manage BMW Group’s national launch of its new generation 6 Series Gran Coupe.

“We were one of the first sound companies to adopt Allen & Heath’s new GLD system in Russia, and had already tested the system at several top level events before the BMW presentation, so we had no doubts about the system’s capabilities,” comments Alexander Kosarev, General Director of City Sound.

Hosted on a specially constructed rooftop stage in downtown Moscow with panoramic views of the city, the agenda included an overview with a sound and light show demonstration of the car, plus performances from a live band and a DJ.

“GLD has proved to be very reliable and we are especially happy with the quality of sound,” said Kosarev. “We originally purchased the system for our smaller events but our experiences have shown that we can rely on GLD to manage any event.”

University Of Virginia’s Chooses Danley For Memorial Gymnasium

As part of its commitment to keeping Memorial Gymnasium in tip-top shape, the school recently renovate the sound reinforcement system with Danley Sound Labs loudspeakers and subwoofers.

Known affectionately to the students at the University of Virginia as “Mem Gym,” Memorial Gymnasium was constructed in 1924 to provide a home for the school’s basketball team. The 2,500-seat facility currently serves as a workout center and home to the school’s volleyball, wrestling, and intramural sports teams.

As part of its commitment to keeping the facility in tip-top shape, the school recently hired dB Audio & Video of Gainesville, Georgia to renovate Memorial Gymnasium’s sound reinforcement system. In order to deliver intelligible speech and spirit-motivating bass, dB Audio & Video installed Danley Sound Labs Synergy Horn loudspeakers and Tapped Horn subwoofers, with Danley Sound Labs processing and amplification at the front end.

The previous sound system was centered on four clusters of horns that fired down from the rafters. Because the brick walls are untreated and because the horns had poorly-controlled patterns, significant energy bounced around the room, effectively masking speech and undermining intelligibility.

“It was an echo chamber,” explained David Clark, operations manager at dB Audio & Video. “It was very difficult to understand what was being said.”

Clark presented proposed the Danley Sound Labs solutions because their Synergy Horn technology not only delivers point-source, hard-pack arrayable, phase-coherent sound, but it also delivers well-defined pattern control all the way down into the low octaves.

“With the Danley boxes, I was able to keep all of the energy on the bleachers and off of the walls,” said Clark.

Danley’s Synergy Horn line contains a diversity of boxes with different beam widths for different situations. At Memorial Gymnasium, the Danley SH-69’s 60x90 pattern fit the bill perfectly.

Clark used a total of eight Danley SH-69s, three each on either end of the building and two at the midline.

“The athletic director also requested some low end to help pump up the crowd,” recounted Clark. A pair of Danley TH-118 subwoofers fulfilled that request wonderfully with Clark mounting them in the rafters, splitting the distance between the three clusters of SH-69s.

A Danley DSLP48 DSP provides modest input tuning, as well as loudspeaker conditioning and protection. A pair of Danley DSLA-3.3k amplifiers powers all of the SH-69s, and one Danley DSLA-6.5k amp powers both subwoofers.

“With Danley processing and amplifiers, I always know that I’ll have the flexibility to meet the requirements of the system and the power to make it sound its best,” said Clark. “And it’s a very clean installation when everything comes from the same manufacturer. It looks good, and you know everything is matched to work well together.”

He continued, “The system turned out sounding really nice. The intelligibility improved one-hundred percent, and now the fans can understand everything that’s being said.

“Moreover, we were able to position the loudspeakers and subwoofers high above the rafters – above the light fixtures even – so that the aesthetics of the building remain intact. With the clarity of the Danley SH-69s and the undistorted thump of the Danley TH-118s, the sound quality of music in Memorial Gymnasium is now amazing!”

Sennheiser Provides Authentic Sound Via Wireless Headphone Technology At Newport Folk Fest

Attendees were able to experience performances from festival artists via Sennheiser RS 120 wireless headphones

Sennheiser, in conjunction with event partner Paste Magazine, recently hosted a live broadcast/recording studio session housed in an alcove of an 18th century fortress, located on the site of this year’s Newport Folk Festival.

By donning a pair of Sennheiser RS 120 wireless consumer headphones, music fans were able to experience performances from festival artists, including Of Monsters and Men, Tom Morello, Jonah Tolchin and 26 others.

Wherever possible, the entire audio chain consisted of Sennheiser related technology — including microphones from subsidiary Neumann and Sennheiser, pre-amplifiers from distributed brand TRUE Systems and wireless RF technology from Sennheiser.

The two-day recording session presented challenges, including a live sound stage located just 100 yards away and an extremely reflective — and somewhat leaky — recording environment.However, the wireless headphones were still able to deliver a clean and quiet performance, faithfully representing the artists’ sounds.

Microphones on stage and in the room included several Neumann TLM 49s and KM 184s, two U 87s and a pair of Sennheiser e 906s. The microphones were connected to a pair of TRUE Systems Precision 8 preamplifiers, which — through a special feature on the back panel of the unit — split the signal and subsequently routed it to both a multi-track recording rig as well as a live mixer.

Each of the Sennheiser wireless headphones received a live stereo mix of the multitrack recording sessions courtesy of Nashville-based engineer Steve Ledet. A Sennheiser A5000CP antenna was strategically placed in the rear of the grotto, providing a generous amount of RF coverage both inside and outside the grotto.

In addition to having many pairs of wireless headphones on hand, Sennheiser set up a special VIP seating area where listeners could audition an assortment of Sennheiser’s audiophile and professional headphones, including the HD 600, HD 650, HD 700, HD 800 and the new Amperior.

“Each of the performers we hosted at the Sennheiser Sound Lounge at the Paste Ruins takes an enormous amount of pride in the craftsmanship and honesty of their songs — this is of paramount importance to them,” says Tim Moore, artist relations manager, Sennheiser. “By selecting a complete signal path of Sennheiser family gear before and after the mixing console, we were able to ensure the integrity of the audio at almost every stage. As a result, the performers were able to establish a more direct and honest connection with their fans.”

Singer/songwriter/guitarist Jonah Tolchin, who performed on the second day of the festival, found the Sennheiser Sound Lounge at the Paste Ruins particularly inspiring. “This is just incredible,” he states. “In this environment, with all these great mics, you are so zoned in and focused with all your heart and soul.”

Clips of the performances will be made available for viewing via Sennheiser’s social media outlets over the next several weeks.

To Match Or Not To Match? Paying Attention To Impedance

Principles involved in feed a number of inputs from a single signal source

A common task in “audioland” is the need to feed a number of inputs from a single signal source. This may include driving a rack of amplifiers, providing feeds to the press, or distributing a signal around a building or campus.

The methods used to accomplish this range from the profoundly simple to quite complex, and the appropriate method can only be determined after sizing up the situation.

Impedance matching means that an output is terminated with a “mirror” input impedance. This configuration yields maximum power transfer, and more importantly, reduces reflections from a load back to the source.

In multimedia systems, the matched interface is used for very high frequency signals. These include video, antenna and digital interfaces.

One drawback of the matched interface is that active or passive splitters must be used if the source must drive multiple inputs. Otherwise the impedance match is violated and problems result.

One of the most common mistakes in audio is to attempt to apply this interfacing method to the basic analog interfaces that dominate today’s sound reinforcement systems.

In a constant voltage interface, an electronic signal source with a low source impedance (i.e. an output) is used to develop a signal voltage across a high load impedance. The minimum ratio between the source Z and load Z is one order of magnitude (1:10).

This scheme is used universally in the audio industry for passing signals from component to component. One utility of this interface is that it provides the possibility of driving multiple parallel loads from a single source without additional hardware.

The stipulations are as follows:
—The parallel combination of all loads cannot violate the 1:10 minimum impedance ratio.
—The path length (interconnecting cable) must be short when compared to the wavelength of the highest frequency component of the signal.

Figure 1: The relative lengths of an audio waveform, a VHF waveform, and an audio cable. (click to enlarge)

Because the speed of propagation of electricity approaches the speed of light, and audio cables are typically less than a few hundred feet, the second condition is easily met in the bulk of audio applications.

Radio frequency, digital, and video signal wavelengths are much shorter, and the impedance-matched interface must be used in lieu of the constant voltage interface to prevent signal degradation. (Figure 1)

“Y” TO THE RESCUE
Figure 2 below shows an equivalent circuit of a single source driving multiple loads. Note that even though the load impedances are not the same, this is a parallel circuit so all of the inputs have the same voltage impressed across them.

Signal distribution requires a simple “Y” cable connected from the source to the multiple loads. This is a perfectly acceptable method of distributing the signal from a source to multiple loads.

There is no need for impedance matching if the components involved are typical analog audio products or even digital products if they are being fed an analog signal.

A drawback to Y-cable signal distribution is the lack of isolation between the individual loads and the source. For instance, a short circuit across any of the inputs will kill the signal to all of the inputs.

For this reason (and others), this method is not recommended for driving loads that lie outside of the equipment rack that houses the source. In these cases, load isolation can be achieved by using a distribution amplifier (DA).

Figure 2: An equivalent circuit of a single source driving multiple loads. (click to enlarge)

The DA provides a single high impedance input for the signal from the source, but provides buffered low impedance outputs that can be used to drive the remotely located loads. The load buffering is achieved by using an active stage for each of the DA’s outputs.

A short across any one output is buffered from the other outputs by the active stage (Figure 3). Note that this is not impedance matching since the output-to-input impedance ratio is still at least 1:10.

Figure 3: Isolation between source and loads. (click to enlarge)

It must be strongly emphasized that while the Y-cable makes an excellent signal splitter it should NEVER be used as a mixer. Doing so places the source device under a load, resulting in an increase in output current that can lead to distortion under high signal conditions.

When a mixer is needed - get a mixer.

IN THE WOODS
While the DA solves the isolation issue, we’re not out of the woods yet. Another problem that plagues distribution systems results from multiple ground connections between the various components.

These “shared” ground paths include the AC safety ground, the cable shields, and possibly connections to the building ground through equipment racks, etc.

Noise currents will circulate through these “ground loops” (Mother Nature does this without our permission) and possibly infect the audio signal if this parasitic ground current finds its way onto a circuit board.

Isolation devices can allow the audio signal to be coupled from an output to an input with no physical wire joining the two circuits, eliminating at least one of the ground loops.

Transformer isolation allows the signal to be coupled via induction (Figure 4).

Optical isolation uses pulsed light to couple the signal, but usually requires that the signal be converted to a digital format.

The transformer has an advantage in that the signal can remain in analog form.

Figure 4: An isolation transformer. (click to enlarge)

The irony is that the same mechanism that allows a signal to be coupled between two circuits inductively also allows power supply fields to be coupled into ground loops (Figure 5).

We’re faced with the common engineering task of maximizing the effect when it helps us and minimizing it when it is working against us.

Putting all of these mechanisms to work, an active distribution amplifier with transformer balanced inputs and outputs may be the optimum way of distributing an audio signal to multiple components.

Figure 5: Ground loops and power supply radiation form an unwanted transformer in a sound system. (click to enlarge)

The active stages buffer the inputs from short circuits, and the transformers allow ground loops to be interrupted while allowing the signal to pass, while at the same time providing excellent common-mode rejection.

Many DAs also include level controls for each output, allowing the signal level to be optimized for mic or line level devices.

When distributing an audio signal to multiple inputs, don’t overlook the simplicity of simply using a properly wired Y-cable to accomplish the task. If the signal needs to extend beyond the rack, a good DA will easily justify the investment.

Our Lady Of Fatima Parish Benefits From Tannoy QFlex Loudspeakers

The installation of a pair of Tannoy QFlex 16 digitally steerable array loudspeakers at Our Lady of Fatima in Seattle, WA has eradicated difficulties parishioners had hearing the Word, while maintaining the parish’s ability to offer historically accurate musical performances.

The installation of a pair of Tannoy QFlex 16 digitally steerable array loudspeakers at Our Lady of Fatima in Seattle, WA has eradicated difficulties parishioners had hearing the Word, while maintaining the parish’s ability to offer historically accurate musical performances.

The existing sound system was installed back in 1968 when the new church was built. Needless to say, it was long overdue for a change.

“It was at least thirty years old,” says music director, Matthew Loucks. “Some speakers weren’t functioning and many had been clustered on one side of the sanctuary. In order to hear speech on the opposite side of the room the system had to be very loud – it was a very lopsided configuration.”

As part of a 2010 audio upgrade, a new pipe organ was purchased, while existing wall-to-wall carpeting covering the 650-seat sanctuary’s was removed replaced with Terrazzo flooring. While that enhanced the sound of the choir and encouraged the congregation to lift up their voices in song, it only exasperated the overall lack of vocal intelligibility during services. The church leadership hired Lynwood, WA-based Morgan Sound to design and install a new sound reinforcement system with the primary goal of speech intelligibility.

“Even when we had carpet, it was impossible to hear articulated speech in the back of the room,” says Stephen Weeks, A/V consultant and project manager for Morgan Sound.

Weeks specified a pair of Tannoy QFlex 26 digitally steerable arrays to dramatically enhance speech intelligibility and subtly reinforce musical performances by resident ensembles and visiting performers like The Vienna Boy’s Choir.

“The QFlex array speakers sound natural, clean and clear; particularly in the articulation of high frequencies,” explains Weeks. “QFlex just does a better job in the 4k to 20k range than their competitors and we could manipulate the beam substantially, so less energy is directed at the front of the room and, as you go further back, it gets louder.”

The compact footprint of the QFlex 16 also appealed to aesthetic concerns the church leadership had voiced to Weeks. Mounted discreetly on either side of the altar behind acoustic cloth on an imposing white rock wall their visual impact was minimal while their sonic impact substantial.

“I have nothing but high praise for them,” Loucks says. “There are only two speakers, but they do the job extremely well. QFlex saved us from the hassle and cost of applying acoustic treatments, and they allowed us to preserve the reverberant environment we wanted for music.

“When you’re reading from scripture, you want the Word to be understood all the times. Now, even when there are only a handful of people at our daily 8 AM mass, speech is highly intelligible.”

Cross Pointe Ministries Selects WorxAudio Technologies

To ensure a high level of speech and music reproduction capabilities throughout the seating areas, the church installed a new sound system consisting of WorxAudio X1i-P line array and TL218SS-P subwoofers.

The Cross Pointe Ministries campus recently celebrated the opening of their new building that provides seating capacity for over one thousand worshippers.

To ensure a high level of speech and music reproduction capabilities throughout the seating areas, the church installed a new sound system consisting of TrueLine components from WorxAudio Technologies.

Terry Hayes, owner of Tupelo, MS-based Pro Concert Music, Inc., was contracted to design and deploy the church’s new sound reinforcement system.

After discussions with church management to ascertain their goals for the system, Hayes deployed a central cluster consisting of six WorxAudio Technologies X1i-P powered line array elements augmented by two WorxAudio TL218SS-P powered subwoofers—one on each side of the stage area.

“In addition to consistent sound coverage, we were very concerned about the visual aesthetics of the space and, on that note, wanted to minimize line of sight issues,” explained Hayes. “For this reason, we elected to install a central loudspeaker cluster.

“These speakers needed to have broad horizontal dispersion and this was a key factor in our selection of the WorxAudio X1i-P. With a dispersion pattern of 160 degrees horizontal by 10 degrees vertical, we determined that a 6-element hang would properly fill the space.”

“I provided the WorxAudio Technologies support staff with the measurements of the room and emphasized the need to ensure coverage across the sanctuary’s 120-foot width,” Hayes continued. “After WorxAudio modeled the space in EASE Focus 2, I proceeded to install the system based upon their recommendations.

“I emphasized the fact that this building is metal construction with a concrete floor, as I was very concerned about echoes. WorxAudio’s TrueAim Grid made the process of installing the loudspeakers a remarkably easy task.

“The bottom of the cluster is positioned 21 feet above the congregation floor and, thanks to the precise throw of the loudspeaker enclosures, echo was held to a minimum. With the congregation in the church, there was no need for acoustical treatment!”

In addition to the six forward facing loudspeakers, there is an additional X1i-P mounted on the rear of the TrueAim Grid. This loudspeaker is positioned down toward the stage and serves as an on-stage monitoring system. It is completely hidden from the congregation’s view.

“The two WorxAudio TL218SS-P subwoofers do a terrific job of providing the low end punch for the system,” Hayes added. “With two 18-inch transducers in each enclosure, there’s plenty of low frequency sound from this system.

“Music plays a prominent role in worship services here, so these subs are a vital part of the overall sound. The fact that the entire system is self-powered was yet another factor that figured prominently in my selection of the WorxAudio equipment, as it minimized noise and power loss from long cable runs and the amps with DSP are part of each enclosure’s design.

“As a result, there was no need to find a space to house a rack of heavy power amps.”

Being a member of Cross Pointe Ministries, Hayes knew that any shortcoming of the sound system would haunt him on a weekly basis. He knew he could count on WorxAudio’s customer support services to help him design and deploy the right system.

“WorxAudio’s support was terrific,” Hayes reports. “They did a great job of modeling the room and had my back every step of the way—all without incurring any additional expense. Speech intelligibility is terrific and the sound remains consistent throughout the entire space. The client is thrilled and I’ve had several other churches come by to listen and observe the new system. I can say with confidence, they’re the best speakers I’ve ever heard!”

CPL Takes Delivery Of Its First Yamaha CL5 Digital Console

Also have sights set Yamaha’s new CL1 and CL3 variations

West Midlands, UK-based AV specialist Central Presentations Ltd. (CPL) is one of the first UK rental companies to take delivery of the Yamaha CL5 digital mixing console, introduced earlier this year.

CPL already has a large stock of Yamaha LS9 and other desks. One reason the CL5 was chosen is that it runs on the same operating principals as these, so all their engineers who are used to working with Yamaha digital consoles will be able to use the CL5 immediately, and quickly familiarize themselves with its many features.

The CL5 system was supplied to CPL by the Birmingham office of LMC Audio Systems.

“The compact size and weight for 72 channels is a ‘no brainer’,” explains CPL managing director Matthew Boyse, who adds that it is “perfect“ for so many of the corporate events and presentations that CPL services. “It is a truly multi-purpose console that will fit neatly into any space and transport very easily.”

The CL Series is the first Yamaha console family to run natively using the Dante digital audio network protocol, with connections between Dante elements via Cat5e cable further reducing overall weight and truck space requirements.

Other Dante devices can be connected to the network keeping the domain completely digital, and in this context, CPL’s CL5 was supplied with two Yamaha RIO-3224-D stage racks giving 64 inputs and 32 outputs which connect via Cat5e in a simple daisy-chain or redundant star-network. Up to eight RIO stage-boxes can operate on the same network, including the smaller RIO1608-D, providing excellent expansion and audio distribution potential.

James Lawford, sales manager at LMC Audio Systems, states, “The availability of the RIO-1608-D stage box, and the move towards Dante by other third party manufacturers, will allow CPL to harness the power of a fully integrated digital audio network, working across standard Cat5e cabling and Ethernet switches, future-proofed with the move towards AVB, and with the reliability, ease of use and wide industry acceptance of a Yamaha console.”

The CL Series also includes a Premium Rack with a Rupert Neve Designs five band Portico 5033 equalizer and a Portico 5043 compressor/limiter. Up to eight Premium Rack devices can be assigned, including VCM technology emulations of other classic analog devices.

Via Dante, the console is also optimized for very straightforward live multitrack recording, utilizing Steinberg Nuendo Live that is supplied with the system and runs on Mac or PC, or any other digital audio workstation.

Nigel Griffiths of CPL notes, “You can set the system up to minimize the need to run analog multicores and the multitrack record and playback facility, without needing additional sound cards or having to stray back into an analog domain, is brilliant. I can’t wait to get my hands on it.”

CPL is already anticipating hot demand for the console and it becoming a valuable cross rental item. CPL has arranged with LMC to provide training days for both its full-time and regular free-lance engineers and technicians, enabling them to maximize their experience with the console.

In addition to further CL5 purchases, Boyse also has his sights set on Yamaha’s new CL1 and CL3 variations, which will become available late summer, the idea being that the company will stock the full CL range.

Line 6 Ships StageScape M20d Smart Mixing System For Live Sound

StageScape M20d streamlines and accelerates the process

Line 6 has announced the availability of StageScape M20d, a smart mixing system for live sound with a unique touchscreen visual mixing environment.

The visual mixing system replaces the traditional mixer channel strip with intuitive touchscreen control. In Perform Mode, a graphic display of the stage setup uses icons to represent each performer or input.

Further, a color-coded encoders provide immediate access to level control. A single touch on a performer’s icon gives access to all parameters relating to that channel, from basic tweaks to deep effects editing.

The audio signal chain can be controlled via an X-Y tweak pad. Drag a finger toward common sound descriptors like “bright” or “dark” and multiple parameters adjust simultaneously to achieve that sound.

Deep Edit mode gives more experienced operators access to every effect parameter via a familiar plug-in style interface.

StageScape M20d streamlines setup with auto-sensing mic and line inputs and outputs that can detect when a connection is made and automatically configure the channel gain, EQ, effects and routing.

A host of recording options are also available. StageScape M20d provides multi-channel recording in high-resolution, 24-bit WAV files to SD card, USB drive or direct to computer, enabling easy capture of every rehearsal and performance.

StageScape M20d provides professional-grade effects on every channel, including fully parametric EQs, multi-band compressors, feedback suppression and more.

In addition, four master stereo effects engines are available, comprising reverbs, delays and a vocal doubler. Users can configure channel effects quickly with a wide range of channel presets that cover everything from individual drum settings to lead vocals.

The mixer can be controlled by using one or more devices with StageScape M20d. This makes it possible to set individual monitor mixes from the stage, or adjust the front-of-house mix from any location inside the venue.

Equipped with the L6 LINK digital networking protocol, StageScape M20d allows easy configuration and control of PA systems of any scale. Connect StageScape M20d to L6 LINK-enabled StageSource speakers and the system automatically configures stereo signals and effects, sets individual component levels and adjusts individual loudspeaker performance.

“For musicians who take care of their own live sound, getting great results consistently can be a time-consuming and frustrating experience—particularly when they want to be focused on performing,” says Simon Jones, vice president of new market development at Line 6. “StageScape M20d answers those challenges by reinventing mixer workflow to better empower musicians to dial in a great mix with speed and ease.

“With a smart design to dramatically reduce setup time,” he continues, “intuitive touchscreen control that simplifies complex mixing tasks, and premium mic pres and effects to ensure the best sound quality, StageScape M20d will deliver great sound in a range of situations.”

Innovason Mixes Jekyll & Hyde During Szeged Open-Air Festival

Dóm Square in Szeged, Hungary, (literally, Cathedral Square) is one of the largest squares in Hungary. Every year its 12,000 square metres of open space are transformed into a 4,000-seat auditorium to host the Szeged Open-Air festival. This year's event was mixed on an Innovason Eclipse GT digital console.

Dóm Square in Szeged, Hungary, (literally, Cathedral Square) is one of the largest squares in Hungary. Every year its 12,000 square meters of open space are transformed into a 4,000-seat auditorium to host the Szeged Open-Air festival.

With a tradition stretching back over 75 years, the festival is Hungary’s largest open-air theatre and music event and the most visited summer cultural event of the region.

The unique nature of the festival with its stunning backdrop of the Szeged cathedral is enhanced by a flamboyant program of world premieres and internationally ranked stage shows and concerts, and every year, the stakes are higher in the quest for technological perfection and flawless sound.

This year, ES Audio’s Sandor Elek, who has been managing audio for the festival for the last 12 years via his rental company, Votec, decided to raise the bar even higher and opted for a combination of his own loudspeaker system with Innovason digital mixing consoles and digital microphones from Neumann.

The season opened this year on July 6th with a 3-day run of Wildhorn’s acclaimed Broadway musical of Jekyll & Hyde, controlled and mixed by an Innovason Eclipse GT digital console accompanied by an Innovason Sy80 for the radio mics.

“My goal is to improve the sound year on year,” explained Sandor. “We already made a big difference last year in working with internationally renowned classical engineers such as Carsten Kümmel and Thomas Mundorf whose approach to classical music and in particular their knowledge about the use of condenser microphones measurably improved the sound quality.”

Sandor also deployed his own loudspeaker system that he developed specifically for music and theatre use.

“I couldn’t find anything on the market that fulfilled my requirements for transparency and flexibility for classical music applications, so I built my own!” he said with a grin.

This year, following a number of conversations at ProLight +Sound and, importantly, an introduction to PANDORA, the new panning algorithm on the Eclipse GT console, Sandor decided to take things to the next level and deploy an Eclipse GT for the festival.

He got in touch with the local Innovason partner, Microsound in Budapest to supply the Eclipse GT, as well as an Sy80 for Jekyll and Hyde.

“The PANDORA function is amazing,” stated Sandor. “I didn’t think it was possible to make such a difference to the definition of the stereo image for the audience just by turning a pan pot, but PANDORA makes it possible.

“You can hear a true stereo image that goes from full left to full right and back without any loss of signal for those sat at the extremes. It’s incredible.”

He also decided that given Eclipse’s capacity to control all the parameters of Neumann digital microphones from the control surface, this would be the perfect occasion to try them out and improve sound quality still further by dramatically reducing any noise coming from analog circuitry and cabling.

Sandor therefore arranged for a 40-channel set of digital microphones and four Neumann DMI stageboxes to be run by the Eclipse GT at FoH in the capable hands of tonmeister Carsten Kümmel.

The Sy80 was installed to handle the feeds from the radio microphones of the singers and the choir. This mix was then sent to the Eclipse GT where it was mixed with the orchestra (all using Neumann digital microphones) to provide the main mix which was then diffused by the ES Audio PA system.

“It was a real pleasure to mix this event with the technical set-up we had here,” confirmed Carsten Kümmel.

“What more can you wish for with classical music than a wide open, transparent image that highlights the natural colorations and blending of the different instruments,” he remarked. “The MARS system also proved its worth as I used it constantly to fine-tune the system using the tracks I had recorded during rehearsals.”

Sandor Elek was equally pleased with the results. “I was impressed by the quality of the orchestra sound,” he said. “Carsten’s mix worked really well throughout the 4000- seat auditorium, no matter where you were placed. You could hear everything from everywhere. It’s going to be a real challenge to improve on this next year!”

At the same time Innovason used the opportunity to show this setup to interested clients and business partners.

On Friday over 30 guests from all over Hungary enjoyed a half day of seminars and presentations by Marcel Babazadeh (Innovason), Eric Veres (ES Audio), Imre Selmeci (AudioPartner) and Carsten Kümmel (Tonmeister) in the nearby REÖK palace. The second part of the day took place at the Dom Ter with a hands-on training session and demonstration of the full system using the original tracks taken from the rehearsals recorded by the Eclipse’s onboard MARS multitrack recording system.

Macy’s Brasil Campaign Kicks Off With RCF Loudspeakers

Philadelphia based Mitta Sound was tasked with providing sound systems for each of the events during campaign kick-off. A long-time RCF user, owner Terrence McDuffy utilized a variety of RCF loudspeakers to handle the diverse sound requirements of the day.

Macy’s recently kicked off their tribute to Brasil with in-store celebrations at key locations across the county.  The purpose of the “Brasil: A Magical Journey” campaign is to celebrate and bring awareness to the culture and history of Brasil and its people through clothing lines, home furnishings, jewelry and more.

The Center City, Philadelphia store was one of the day-long kick-off locations. Throughout the day shoppers were provided with an assortment of live music and dance performances in various locations throughout the store.

Philadelphia based Mitta Sound was tasked with providing sound systems for each of the events. A long-time RCF user, owner Terrence McDuffy utilized a variety of RCF loudspeakers to handle the diverse sound requirements of the day.

The Macy’s store in Philadelphia features a large, open atrium, which was the focal point of the in-store campaign kick-off.  Alo Brasil, a full, 11-piece band – drum, bass, percussion, guitar, trombone, trumpet, 2 dancers, 2 back-up vocalists and the lead singer – performed throughout the day playing an eclectic mix of Brazilian music.

“Because the stage was located in an open atrium – which was five stories high – it was important to be able to steer the beam to cover the first floor and eliminate potential reverberation in the atrium,” explains McDuffy. “We set up the system to throw 75-100 feet to cover the first floor of the store and it worked extremely well.”

McDuffy specified a left-right RCF TTL11A active column array system for the main stage.

Each stack consisted of a TTL11A-H HF module loaded with a 2.5-inch neodymium compression driver with 1.5-inch exit throat and a TTL11A-B bass frequency module equipped with four 8-inch neodymium woofers with 2.5-inch voice coil. The TTS26-A subwoofer, featuring two high power 15” neodymium woofers, added the extra bass to drive the low end of the system. 

The overall effect was a high definition live sound system ideal for Brazilian music. McDuffy also provided eight stage monitors – four RCF TT25-SMA and four dBTechnologies M12-4 – for the onstage performers.

Although the main action was occurring in the atrium, there was additional entertainment taking place throughout the store. Mitta Sound provided small sound systems for these events as well.

The children’s department had a 20 person dance troupe performing, while the women’s and men’s departments offered their shoppers DJ music.

Once again McDuffy turned to his RCF inventory to provide solutions.

“I put a pair of the TT08 on sticks in both the children’s and women’s departments,” he explains. “Those boxes are our workhorses – we use them for everything and they never disappoint. The DJs were very impressed.”

The compact TT08 is loaded with a 90 x 60 horn, 8-inch neodymium driver and 2.5-inch copper voice coil. With a maximum SPL of 125 dB, the pairs were more than sufficient for the DJ music and the dance troupe in both locations.

Although similar to the women’s department, the DJ in the men’s department was required to cover a much larger area, which led McDuffy to use a pair of RCF TT25A loudspeakers – again on sticks – to disperse the sound to a larger area. 

“We placed the TT25As in the balcony that overlooked the men’s department to cover the entire area,” McDuffy continues. “It sounded fantastic and the folks at Macy’s were extremely pleased.”

TT25A is a full range, versatile two-way active loudspeaker system. The high frequency section is a constant directivity CMD horn loaded to a 1.5” neodymium compression driver with a 3” diaphragm assembly for smooth, controlled dispersion. The low frequency transducer is a 15” neodymium woofer with a 4” voice coil.

“It was a very exciting day at Macy’s – being one of the anchor stores for the launch of this campaign was a very big deal,” McDuffy concludes. “The RCF gear never disappoints. All of the performances throughout the day were extremely well received and sounded terrific.”
