EDEN HIGH SCHOOL PUMPS UP HOME GAMES WITH ASHLY GEAR

EDEN, NEW YORK – JUNE 2014: Eden High School graduated its first class in 1899, when the small town of Eden was not a suburb of Buffalo, New York, eighteen miles to the north. Since then, the high school has been consistently recognized for its academic achievement and for the tenacity of the Eden Raiders sports teams. Indeed, the girls’ volleyball team is vying for its fifth straight state championship! In addition to volleyball, the school’s 1,300+ seat gymnasium hosts home basketball games and wrestling tournaments, but until recently, its sound reinforcement system was underpowered and frequently unintelligible. Harvey Electric and Sound of nearby Hamburg, New York designed and installed an abundantly powered and highly-intelligible sound reinforcement system using an Ashly nX-Series amplifier and a ne-Series processor.

“The previous system wasn’t particularly old, it just didn’t meet the needs of the space,” explained Greg Harvey, owner of Harvey Electric and Sound. “The Eden All Sports Boosters raised the funds for a replacement because it was so obvious to everyone that a vast improvement was needed. The system couldn’t overcome a cheering crowd, and even when everyone was quiet, it was still difficult to understand what was being said.”

The inputs to the system are simple and a mere update from the previous system: a new Shure wireless microphone, a new Shure announcer microphone, and an auxiliary input. It’s what happens after that point that makes all the difference. The inputs feed an Ashly ne4400 4-in x 4-out Protea™ DSP System Processor. “The old system was a simple mixer-amp, and the Ashly ne4400 is a vast improvement,” said Harvey. “It gave us the ability to shape the sound with compression, limiting, equalization, and filtering. We also gave them feedback suppression modules on the microphone inputs.”

Outputs from the ne4400 feed a four-channel Ashly nX 1.54 amplifier, which packs four channels of 1500W output into just two rack spaces. “This is our first experience with Ashly’s nX-Series amplifiers, and we chose the nX 1.54 for its tremendous output capacity,” said Harvey. “It sounds great and delivers as promised.” Right now, only two of the amplifier channels are in use. They power two EAW VFR159i loudspeakers, which will be doubled for the other side of the room once the funds become available. The remaining two channels on the Ashly nX 1.54 will power them.

An Ashly WR-5 wall-mounted remote control gives users simple control over input gains and overall volume. Once the system expands to four cabinets, Harvey will reprogram the WR-5 to allow preset selection for different types of events as well. “We went with Ashly for a couple of reasons,” he said. “Ashly’s rep firm in the area, Eaton Sales, does a great job. We’ve worked with them for twenty years. Ashly’s pricing is very competitive, but they don’t make a cheap product. The processors and amplifiers sound great and are very functional and rugged. This is the second installation of Ashly Audio products at Eden High School and we are confident that they will have great sound systems for a long, long time.”

Symetrix Radius 12×8 Dante™ Network DSPs Help Revitalize St. Peter Catholic Church

OMAHA, NEBRASKA – JUNE 2014: The Diocese of Omaha erected St. Peter Catholic Church in Omaha, Nebraska in 1926, and the church enjoyed many decades at the heart of Omaha’s Catholic community. However, times changed, demographics shifted, and the church didn’t have the funds to keep up with needed maintenance. It fell into disrepair. However, a recent resurgence in attendance inspired by the leadership of Fr. Damien Cook motivated the diocese to fund a major external and internal renovation at St. Peter Catholic Church. Now complete, the renovation, designed and coordinated by Conrad Schmitt Studios of Milwaukee, Wisconsin has won awards and features a new sound reinforcement system anchored by a Symetrix Radius 12×8 Dante network audio DSP system with Symetrix ARC wall panel remote.

“It was a complete overhaul, from the roof to the floors, from the walls to the ceiling, everything is renovated and revitalized,” said Tim Burkhart, senior systems designer with Omaha-based Midwest Sound & Lighting, the firm that installed St. Peter’s new sound reinforcement system. “It’s really stunning. In the process, they knew they would radically alter the room’s acoustics. They wanted to ensure that the new sound system would give them musical impact and intelligibility.”

Milwaukee-based DSH Audio Visions designed the sound system and partnered with Scott Riedel Associates of Milwaukee for acoustic design. David Hosbach, DSH president and principal design consultant concurred with Burkhart, and added, “Father Cook and Music Director Zachary Turner understand that while the music portion of Mass is really important, if worshipers can’t hear the Word clearly the rest of it – the majestic music, the ornate worship space – really doesn’t matter. I take my hat off to them and the St. Peter congregation for allowing the sound design, the room acoustics and the architectural beauty to work together in harmony, so to speak.”

Two Symetrix Radius 12×8 DSPs form the heart of the system. One unit is located at the front of the room, the second unit is located at the back of the room, and they connect via the Dante network. That way, each unit is near to a collection of inputs and appropriate outputs, and because the system integrates completely via Dante, any of those inputs can be sent to any of those outputs. Redundant Dante connections provide a failsafe in case one of the networks goes down – the other network will pick up seamlessly. The Radius units provide sophisticated processing for Crown amplifiers and a Tannoy QFlex 64 steerable line array.

The Radius units are located in a wall rack at the back of the loft and at the main equipment rack in the sacristy at the front of the room. Two remote sets provide user control, with one mounted in the main rack, and the other in the loft in a custom portable box at the organ console. All told, two Symetrix ARC-K1e, five Symetrix ARC-EX4e, and three Symetrix ARC-SW4e wall panel remote control units provide comprehensive, yet intuitive, control of the system. They primarily select active inputs and allow volume adjustment and configuration preset changes. “We use a lot of Symetrix equipment, and we love the hardware, the software, and its bullet-proof reliability,” said Burkhart. “The sound quality is always top-notch, and the Symetrix open-architecture processing is capable of anything we ask of it. Considering how frequently we use Symetrix products, the failure rate is remarkably low. And if something does go wrong, Symetrix makes it right immediately.”

Hosbach commented, “I like the Symetrix SymNet DSPs for the same reasons as Tim. And I’ll add that they are really easy to program, the site files are fast and convenient to move around in and modify on the fly during setup, and the tuning filters are extremely accurate.”

Burkhart concluded, “St. Peter Catholic Church is very happy with the new sound reinforcement system. They are delighted with its sound quality and with its ease of operation.”

LEMON JELLY MAKE MUSIC WITH METRIC HALO PLUG-INS

SAFETY HARBOR, FLORIDA: Nick Franglen is best known as founding member of the British electronica duo Lemon Jelly, releasing three albums on XL Recordings that sold half a million albums worldwide and earned Franglen and band mate Fred Deakin nominations for the Mercury Music Prize and the Brit Awards. “Lemon Jelly’s style is electronic music that doesn’t sound particularly electronic,” explained Franglen. “We’d pull together sounds from a wide range of genres to see what would happen when we mixed them up. They could be sampled or played – it really didn’t matter where they came from – the more diverse the better.” Although Lemon Jelly are currently on a happy hiatus, Franglen maintains an outrageously busy schedule – as he always has – that feeds his creative need to keep things fresh and interesting. “Creativity is all I’m interested in. I hate repeating myself (I get bored very quickly) so I’m constantly challenging myself into innovation. I like being out on a limb – that’s where the exciting things happen.”

Franglen’s talent, prolificacy, and affable nature have earned him a lot of friends and work in the music industry. He’s provided keyboard and beats programming for Björk, Hole, Primal Scream, Pulp, and Blur. In addition to all the Lemon Jelly records, he has produced albums for John Cale and Badly Drawn Boy and remixed Mark Mothersbaugh (Devo), the Pet Shop Boys, and Coldcut. He has written and produced tracks with artists as diverse as William Shatner and John Paul Jones (Led Zeppelin) and regularly plays live with John Cale. As musical director of the Nico tribute show, he has worked with Mark Linkous, Mark Lanegan, Kim Gordon, Mercury Rev, Yeasayer, and many others. Reflecting his unquenchable thirst for the novel and creative, Franglen has performed and recorded electronic gigs down mines, on submarines, and in abandoned government test facilities. As a composer, he has worked on films with Ralph Fiennes, written the music for BBC-TV series, and composed commercials for BMW, Cadillac, Ford, Coca-Cola, Caesar’s Palace, Nordstrom, and many others. “I like to keep busy,” he summarized simply.

In addition to myriad other side projects and jobs, Franglen’s current passion is a solo album that will be released under his own name. “I’ve been developing this material over the past couple of years,” he said. “It’s quite complicated stuff, both conceptually and sonically, and I’m enjoying the challenge.” Like everything else he’s touched (sonically) in the last decade, Franglen has made regular use of Metric Halo’s classic ChannelStrip plug-in in the development of the new material. “I was with ChannelStrip from the very beginning – I had the original version,” he said. “It was the EQ that first got me. It could do things that no other EQ could do, and that remains the case today.”

He continued with an example: “For a while I was really interested in mixing very different samples from very different sources, it could be jazz with punk with something orchestral, whatever. I had to capture the essence of a source and still preserve audio clarity when it was mixed with something else, and Metric Halo ChannelStrip let me do that without having the composition turn to mush. Basically, ChannelStrip’s Q is precise and perfect. I can nail a filter or EQ band to within a few Hertz, enhance the fundamentals and then cut out everything that doesn’t matter while preserving the sample’s character and life. That’s a critical part of what I do and it’s my secret for maintaining audio clarity even when I have a lot of different sources all playing at once. And shortly thereafter I learned the value of ChannelStrip’s dynamics section. It’s so versatile. I use it all the time in combination with the ChannelStrip gate to bring looped drums to life.”

For work on his solo album, Franglen is using Metric Halo’s Production Bundle of plug-ins, which includes all of Metric Halo’s plug-ins: ChannelStrip 3, Character, HaloVerb, Multiband Dynamics, Precision DeEsser, Transient Control, and Multiband Expander. “I’ve found that with Character and Transient Control, I can breathe life and soul into my studio recordings,” he said. “The effect is subtle, but undeniable. The reverb is also fabulous. It has a huge range of sounds, and the smoothness of the tail is beautiful and transparent. It just disappears into the background. When I apply it to individual instruments, it gives them their own space and surrounds them with warmth without ever overpowering them.”

To say that Franglen uses Metric Halo plug-ins would be an understatement. Just as ChannelStrip has been a critical component of his sound over the last decade, the broader Production Bundle palette is fast becoming indispensible. A peek inside one of his new sessions reveals Metric Halo plug-ins on nearly every channel, with many of those channels bursting with multiple Metric Halo plug-ins!

ABOUT METRIC HALO Now based in the sunny city of Safety Harbor, Florida, Metric Halo provides the world with high-resolution metering, analysis, recording and processing solutions with award-winning software and future-proof hardware.

General Cable Launches Gepco® Brand Stadium Cables at InfoComm 2014

LAS VEGAS, NEVADA, JUNE 18, 2014 — General Cable is pleased to launch its line of Gepco® Brand Stadium Cables at InfoComm 2014 (Booth #C10336) June 18-20, 2014. The new line of stadium cables allows for simplified installation of one cable across Direct Burial and Riser applications.

Typical indoor and outdoor applications require the installer to use different cables and splice the two together, which requires more time and also makes the installation vulnerable to signal loss or errors. With Gepco Brand stadium cables, the installer can run a single cable from the outside direct burial environments directly into buildings for riser applications, no splicing necessary.

Gepco stadium cables feature two-ply water-blocking tape and water-swellable fillers (audio only) for advanced water protection in direct burial installations while also retaining a CMR rating. Available in single-pair audio (61801SC), high-definition RG 11 coax (VHD1100SC) and RG 11 triax (VT61811SC), all Gepco Brand stadium cables are ideal for extended-distance runs.

“Gepco Brand stadium cables provide solid performance across two very different applications,” said Brad Pope, Operations Manager, Gepco® Brand Products. “Gepco and General Cable are pleased to provide a solution that makes installation for stadiums and other outdoor venues quicker and easier.”

General Cable (NYSE:BGC), a Fortune 500 Company, is a global leader in the development, design, manufacture, marketing and distribution of aluminum, copper and fiber optic wire and cable products for the energy, construction, industrial, specialty and communications markets. In August 2009, Gepco International was acquired by General Cable. For more information about General Cable products, please contact your local sales representative or visit our Web site at www.gepco.com or www.generalcable.com.

Gepco® has been an industry-leading brand of studio, stage and broadcast AV cables and cable assemblies for 30 years. As a complete solutions-based supplier, Gepco also offers value-added service and distribution of connectors, cable management products, patch panels, and wire and cable accessories.

Gepco® Brand Lightweight and Flexible 7.8 mm Hybrid Fiber Camera Cable Featured at InfoComm 2014

LAS VEGAS, NEVADA, JUNE 18, 2014 — General Cable is pleased to demonstrate the flexible and lightweight, yet durable Gepco® Brand HDC720HD 7.8 mm Hybrid Fiber Cable at InfoComm 2014 (Booth #C10336) June 18-20, 2014. Radically different from typical industry products but with the same performance characteristics of traditional SMPTE 311 cables, the HDC720HD 7.8 mm hybrid fiber cable is 16 percent smaller and 40 percent lighter in design. Visitors will be able to feel for themselves the differences in size, weight and flexibility of the HDC720HD compared to a typical portable 9.2 mm cable and how those differences add up when in use in the field.

The revolutionary construction of the HDC720HD starts with replacing the typical heavy steel strength member with a Kevlar® strength member that has the same pull strength of steel, but is lighter and more flexible. Unlike steel, Kevlar expands and contracts at the same rate as the glass members during temperature extremes, keeping the elements in the cable aligned reducing migration. Using Kevlar in place of steel also means the cable has virtually no memory making the cable easier to pay off, lay flat and wind back up on the drum.

For further durability, the HDC720HD utilizes bend-insensitive fiber elements with very low attenuation and a bend radius of 0.2 mm—versus 2.0 mm for traditional single-mode fiber—in a breakout style with additional Kevlar protection around the individual fibers.

In the HDC720HD, the typical outer braid is replaced with two 18 AWG drain wires and a foil shield that allow the cable to be more flexible, lighter and smaller in diameter. The power conductors consist of two 16 AWG conductors so you can still achieve the same distance to which a regular SMPTE 311 cable performs. The master jacket of HDC720HD is polyurethane material with a glossy finish that reduces the pickup of dirt and debris from outside applications, making it easier to keep clean.

“The HDC720HD design provides a lightweight, flexible solution with the added bonus of reducing migration errors caused by temperature extremes,” said Chris Gazdic, Engineer, Gepco® Brand Products. “This makes the HDC720HD extremely ideal for use in portable applications and with high-definition Steadicams.”

XTA Launches New APA Series at InfoComm 2014

The first model, the APA-4E8, set to be unveiled on Group One Ltd. stand C11336

LAS VEGAS – June 2014 – Group One Ltd. stand C11336 — XTA is proud to be debuting the APA series – short for Adaptive Processing Amplification – at this year’s InfoComm show. APA’s new power and DSP platforms have been designed to interact intelligently and adapt to prevailing conditions, protecting drivers and significantly enhancing performance from all speaker systems.

By including studio-quality analog-to-digital converters at the outputs as well as the inputs, real-time audio currents and voltages presented at the speaker terminals can be fed back into the DSP in addition to processing the incoming audio, allowing the amplifier to adapt and correct its performance continuously. The tight coupling of the power supply’s behavior through real-time monitoring of the mains supply, as well as over ten temperature sense points, means that the amplifier can adjust its power consumption and output drive to ensure that maximum permissible power is always available.

“We have included the same A-to-D converters that we use in the DS8000D [XTA's Audio Distribution System], which allows us to monitor the outgoing audio voltages and currents to the same degree of accuracy as we do when digitizing incoming analog audio prior to processing,” notes XTA Technical Director John Austin. “These outgoing signals can then be fed back into the DSP [responsible for all the user adjustable EQ and protection] so that it can make adjustments to ensure that any connected speaker driver is being utilized to the best of its abilities, without undue stress to the driver, or the amp for that matter.”

The Class D amplifier design, combined with a highly efficient power supply and generous energy storage reservoirs result in an amplifier that not only is better at converting input mains power into output speaker power with less wasted heat (system efficiency is 80%), but is also able to offer better sustained peak power at low frequencies – where you need it most. A quick start mode, and an ultra low power stand-by mode (with a power consumption of under 0.75W) mean reduced running costs in all circumstances.

According to XTA Technical Brand Manager Waring Hayes, “It’s not so difficult to add a DSP module to an existing amplifier design in the form of a plug-in card, but to provide the level of monitoring and feedback within the amplifier that we wanted – that took a little longer!”

The first model – the APA-4E8 – features four channels of power totaling 20kW peak output into four ohms, and continuous power available of 3400W per channel into four ohms. Four audio inputs allow all four amplifier channels to be individually utilized if required with a full suite of XTA’s world-renowned DSP, including dynamic EQ, FIR (and phase linearization) and classic IIR filtering, mix matrix and the manufacturer’s famously transparent limiters and soft knee compressors.

“What with all the feedback from the PSU and mains monitoring and all the temperature sensors everywhere, the DSP really is at the center of things in the amplifier, and far from being bolted on to the front end – it’s more an engine management system than a speaker management system,” Hayes points out.

The APA-4E8 can route audio from analog, AES or network sources with automatic fallback. USB and internal SD cards offer additional audio choices for playback of emergency evacuation messages, and quick upload of presets or download of performance logging data. The APA series also includes extensive GPIO and remote control covered by Ethernet, USB and RS485.

Housed in a 2U chassis and weighing 28.2 pounds (12.8 kg), the APA-4E8 sports an elegant front panel interface with a large color LCD, which, in combination with innovative user selectable metrics and tricolor multimode panel metering, offers reassuring feedback of the amplifier status from any distance.

New remote software written to run natively on both the Windows and Mac platforms is available and operable via an Ethernet or USB connection.

Hayes sums up by adding, “Ultimately, what counts can be distilled down to sound quality, power delivery, reliability, usability, flexibility and blue front-panel-ability!”

PRG Calls K2 Into Active Duty for National Memorial Day Concert

PRG's initial deployment for K2 was at the 25th annual National Memorial Day Concert on the West Lawn of the U.S. Capitol (photo credits: Alan Henig)

Two complete L-ACOUSTICS rigs purchased, one immediately deployed at 25th annual event on the U.S. Capitol’s West Lawn

WASHINGTON, D.C. — Leading entertainment and event production services provider Production Resource Group (PRG) has officially begun upgrading to L-ACOUSTICS’ new K2 platform with the purchase of two complete line source array systems. Delivered in mid-May, the sale comprised a total of 48 K2 enclosures and 24 LA8 amplified controllers.

PRG’s inaugural K2 deployment came almost immediately – two dozen enclosures were put into active duty for the 25th annual National Memorial Day Concert, attended by countless spectators on the West Lawn of the U.S. Capitol in Washington, D.C. on May 26. This year’s event, hosted by actors Joe Mantegna and Gary Sinise, featured an all-star lineup of performers, including the National Symphony Orchestra, Jennifer Nettles, Megan Hilty, the U.S. Army Chorus and Air Force Singing Sergeants.

One of the L-ACOUSTICS K2 arrays

Having supported this annual holiday event for over two decades now, PRG’s new K2 rig replaces the call for V-DOSC used in years past. “PRG has been anxiously waiting for the arrival of the L-ACOUSTICS K2 system and it went right to work at the Capitol for Memorial Day,” says Randy Hutson, GM of PRG Chicago and vice president of PRG Audio. “We’ve been looking for a speaker system that is versatile yet meets the needs of our most demanding clients and L-ACOUSTICS has delivered with the K2. It is a high-powered, full-range speaker that weighs less, has a small footprint, offers excellent audience coverage with superb audio qualities and can easily support multiple markets, from music concerts to corporate events.”

“The K2 gives us more reach into large-scale venues, such as arenas and stadiums, but does so at significantly reduced weight without sacrificing power,” says Mark Boettcher, project manager at the Memorial Day event and a senior engineer at PRG. “At the same time, its lighter weight means it can go into venues like ballrooms and expo centers that have a lower-load rigging capacity.

“Also, the K2 enclosures have the same width as the L-ACOUSTICS K1, so it has complete rigging compatibility with K1 and K1-SB enclosures. That allows us to use K2 for downfill on K1 arrays. And all of that has significant economic implications, making the K2 extremely cost-effective. There’s just so much in the way of flexibility with the system.”

At the National Memorial Day Concert on the U.S. Capitol’s massive West Lawn, the K2 rig was configured in left and right hangs of 12 enclosures each. These were flown from towers, also used for fixed and moving lighting fixtures, positioned 105 feet downstage of the stage deck. Eight SB28 subs deployed in an end-fire array configuration provided the low-end reinforcement, while 16 coaxial 12XT wedges served as stage monitors. Thirteen LA-RAK touring racks, each loaded with three LA8 amplified controllers, furnished power and processing for the entire system.

In addition to the K2s, the project also used a total of 24 ARCS II systems – two hangs of five each for the invited-guest main stage, two more hangs of five for the reverse satellite stage, and two hangs of two each flanking the K2 arrays for wide horizontal coverage. Twenty-four dV-DOSC speakers, in four stacks of six enclosures each coupled with a single SB28 sub, provided delay while two more stacks of four dV-DOSC were used as guest area fills positioned on a tower on either side of the stage, also used for lighting fixtures and video screens.

With K2′s new PANFLEX variable horizontal coverage technology, the familiar challenge of surface reflections was easily overcome. “The stage was playing directly into the face of the Capitol building, which is flanked by stairs on either side, but centered on a large, ornate glass window – beautiful, certainly, but nothing we wanted to purposefully fire acoustic energy against,” notes Chris “Sully” Sullivan, L-ACOUSTICS’ east coast application engineer. “To solve the problem, we viewed the obstacle in SOUNDVISION, predicted which elements in the K2 array were going to hit it, then simply shifted the K2′s pattern asymmetrically for just those loudspeakers in the middle of the array. We reduced the reflected energy in excess of 6dB, and that was just the direct reflected energy! Combine that benefit with the reduction or elimination of the myriad of tangential off-time tertiary reflections and that becomes a massive win for the whole audience.”

In terms of overall performance, the K2s were troupers. “What I can tell you is that the K2 system went up very quickly thanks to its lighter weight – much faster than the comparable V-DOSC system it was replacing – and the same goes for taking it down,” says Boettcher, who worked on the event with Alan Henig, co-systems engineer. “And the rig sounded extremely transparent. There tends to be a natural fall off of the high frequencies by the time the sound hits the Capitol steps, but the K2 had extended frequency response past 10 kHz that far out, so the sound was exquisite.”

This year’s Memorial Day concert also saw another first. Previously, the show’s FOH had been mixed using a total of three consoles – a Yamaha PM5D, PM1D and an LS9/32, all connected with multiple copper-cable snakes. This year, PRG ran the entire show on just a pair of DiGiCo SD7 consoles, with six DiGiCo SD-I/O racks and an SD-Mini I/O rack, connected by two fiber-optic cables, with the FOH mix handled by Patrick Baltzell. “This really unified operations at the site and, combined with the much lighter K2 system, gave us the same amount of punch in a smaller and more efficient footprint.”

The same system will be deployed for the July 4th concert event in the same location. “The K2 will set the benchmark going forward as its predecessor V-DOSC did when it was released years ago,” Hutson declares. “Along with K1, this gives L-ACOUSTICS the leading edge in line arrays and we at PRG are very excited to add K2 to our extensive inventory of L-ACOUSTICS products. They listened to our needs and have delivered an innovative product that will perform for years to come.”
