3G Productions Deploys Martin Audio MLA At EDC Las Vegas

This year’s Electric Daisy Carnival in Las Vegas easily earned its reputation as the world’s largest electronic music festival with seven stages, carnival rides, art installations, fireworks displays and over 400,000 in attendance.

The landmark multimedia three-day event took place at the Las Vegas Motor Speedway and focused on providing a total entertainment experience for EDM fans with over 70 DJs performing each day.

3G Productions of Las Vegas/Los Angeles, who once again provided audio for the event, set up a fully loaded Martin Audio MLA loudspeaker system on Stage Two (Cosmic Meadow) to deliver the power and huge amount of low end required for the shows. DJs featured on the stage included Diplo, Justin Martin, A-Trak, Chromeo, Bassnectar, Dillon Francis and Destructo, just to name a few.

The system for Cosmic Meadow stage consisted of 16 MLA and 2 MLAD enclosures per side, 12 MLA Compact per side for sidefills and 3 MLA Compact per side for front fills. More than the required amount of low end was provided by 40 MLX subs stacked one on top of the other along the front of the stage. A Yamaha CL5 console was used for Front of House and a Yamaha PM5D for Monitors.

Asked about the MLA, 3G’s Keith Conrad said, “the system performance each night was fantastic and the Martin Audio stage blew everybody away. The client (insomniac) was happy with the way MLA performed, the show was packed every day and the DJs and their engineers were really impressed with the system.

“Because Cosmic Meadow stage was facing out towards the speedway and wasn’t competing with any other stage,” Keith adds, “we got the full impact and power of the system, which was amazing. As it turned out, we didn’t even need delay towers because the coverage was so exceptional. This was due in part because of Martin Audio’s Display 2.1 modeling software.

“What makes EDC unique from other music genre festivals is the incredible amount of bass that’s required for EDM. The MLX subs were so powerful, the artists and their crews were smiling from ear to ear as soon as they turned it on.

“Of course,” Keith concludes, “we were fortunate to have our secret weapon FOH engineer Manny Perez who is definitely a veteran with MLA and knows how to tweak the system so it sounds exactly right from the low to high frequencies, which made it an ideal situation for everyone. Overall, I’d say that the system exceeded expectations from every aspect.

Renkus-Heinz Helps Bring Intrepid Museum’s Legends to Life

New York, NY – June 2014…In a city with no shortage of museums, the Intrepid Sea, Air and Space Museum is truly one of a kind. Founded in 1982 as a final home for the historic aircraft carrier USS Intrepid, the museum’s treasures now include the world’s fastest commercial jetliner, the British Airways Concorde; the first space shuttle, Enterprise; and the USS Growler, the only American diesel-powered strategic missile submarine open to the public. More than a million visitors every year tour the museum, which is also home to 27 other authentically restored military aircraft and an 18,000-square-foot education center, all overlooking the famed Manhattan waterfront.

Needless to say each of these grand machines on display has a rich story to tell. But the logistics of telling those stories within the museum’s daunting acoustics is no easy feat. As Leo Garrison of Washingtonville, NY-based Metro Sound Pros explains, each of the museum’s different areas presents its own set of challenges.

“The Space Shuttle Pavilion is a large steel facility, which can be acoustically challenging,” says Garrison. “They’ve got fabric covering the inside walls, which helps a little bit with reflections, but it’s still a very large and reverberant space.”

The Pavilion’s interior, measuring approximately 100 feet by 70 feet, is covered by ten Renkus-Heinz CFX81 two-way eight-inch systems, with five speakers hung, facing each other, on each of the long walls. “We flew them upside down and about 12 feet up,” says Garrison. “We divided the space into essentially five zones, each with left and right speakers. When they have a live event, that enables them to shut off any zone where a microphone will be positioned.”

A pair of Biamp MCA 8150 amplifiers power the system, bridged to provide approximately 300 Watts per pair. A Symetrix Jupiter provides signal delays and processing. “We set up different pre-sets for spoken word presentations and other program material,” says Garrison.

“The CFX81s were really the ideal solution for their needs and for their budget,” Garrison concludes. “The pattern control is excellent, and because the coverage they deliver is so wide — 150 degrees by 60 degrees — we were able to cover an exceptionally large area with very few of them.”

HARMAN’s JBL Professional VTX V20 Line Array Loudspeakers Gain Momentum

LAS VEGAS, Nevada – Since its introduction earlier this year, HARMAN’s JBL Professional VTX V20 line array loudspeaker has been tremendously successful, as it has been adopted by some of the world’s most respected sound companies for some of the most widely-attended festivals, concerts and tours.

Billing itself as the Ultimate Celebration, the 3-day BottleRock Napa Valley Festival offered the best in music, wine, beer and gourmet food, accompanied by stellar sound courtesy of HARMAN Professional audio systems featuring JBL’s V20 line array loudspeakers and Crown I-Tech HD Series amplifiers. Camarillo, California-based full-service event production company Delicate Productions provided sound, light and video for the event

“The VTX line arrays, subwoofers and loudspeakers proved to be exactly what was needed for the application,” said Delicate Productions’ President Jason Alt. “The VTX’s acoustic energy was focused in the right direction, with the correct directivity being delivered forward to the audience and with very little spill to the surrounding neighborhood.”

In addition, Crosby, Stills and Nash’s live sound company Sound Image has upped the performance of its tour sound rig this year, using a combination of JBL V20 line array elements and S25 suspendable, cardioid-arrayable subwoofers

“Typical CSN concert venues vary between sheds in the summer and theaters with a balcony,” notes Gary Sanguinet of Sound Image’s touring division. “Based on the size of the theater, on each side of the stage we’ll hang a split array of six V20 loudspeakers, one or two S25 subs, and six more V20 boxes on the bottom of each hang, and then place anywhere from six to eight additional S25 subs on the ground for additional low-frequency reinforcement.”

Sound contractor CTS Audio was one of the first adopters of JBL’s VTX Series line arrays and it’s safe to say they’ve liked what they heard—the company just purchased more than 100 more of them. CTS Audio added a total of 108 V20 line array loudspeakers to its inventory, plus another eight V25 loudspeakers and a bevy of VTX F Series F12 loudspeakers. While Franklin, Tennessee-based CTS Audio had used the V25 arrays at a number of high-profile events in the past year, the company put the V20 to the test for the first time at the recent 2014 K-Love Fan Awards, held at Nashville’s Opry Hotel and featuring the biggest names in Christian music including Michael W. Smith, Steven Curtis Chapman, Amy Grant, Scott Stapp, Sidewalk Prophets and more than 40 other artists.

“Based on our experience with the VTX Series V25 and S28 subwoofers, we didn’t think we were going out on too much of a limb with the V20’s, which we were interested in for their smaller size and which would give us a more flexible loudspeaker inventory that would be adaptable to a wider variety of venues,” said Mike Taylor, Vice President at CTS Audio.

The VTX V20 loudspeaker features a true 3-way system design with proprietary D2 Dual Diaphragm Dual Voice Coil compression driver and Differential Drive™ low frequency transducer technology along with patent-pending ultra-linear motor technology employed for midrange components. In keeping with the philosophy of the VTX Series, the VTX V20 has extremely high power density with each line array element featuring two 2261H 10-inch Differential Drive™ woofers, four 2164H 4-inch ultra-linear midrange transducers and three of the new small-format D2415K Dual Drivers.

HARMAN’s JBL Professional Delivers More Ceiling Speaker Options to Systems Integration Community with New Control 45C/T

LAS VEGAS, Nevada – Adding to its incredibly successful Control® Contractor 40 Series, HARMAN’s JBL Professional is introducing the Control 45C/T coaxial ceiling loudspeaker. Along with providing high fidelity and smooth, wide bandwidth sound, this 2-way, 5.25-inch loudspeaker offers extremely consistent 120-degree broadband pattern control featuring JBL’s exclusive conical Radiation Boundary Integrator (RBI™) technology.

“The JBL Control Contractor 40 Series has been popular with systems integrators around the world, thanks to its combination of outstanding pattern control and exceptional sonic performance,” said Rick Kamlet, Senior Manager, Commercial Sound, JBL Professional. “The Control 45C/T loudspeaker shares these same qualities makes available for our customers a smaller full-range Control 40 Series model for their projects. We see it as an ideal solution for a wide variety of applications where a smaller size, smooth response and even coverage are desired.”

The Control 45C/T is a premium in-ceiling professional loudspeaker designed for environments that can benefit from extremely wide bandwidth and very consistent coverage from a speaker with a small footprint. Thanks to JBL’s RBI technology, the tweeter sound is well-controlled by a large waveguide, while the low-frequency sound projects through specially designed apertures in the RBI. This design allows for a seamless integration of coverage over a wide bandwidth from coaxially- mounted drivers. The result is that the sound character is extremely consistent throughout the listening space with little variation from location to location. In addition to providing better coverage of the listening area, the constant directivity coverage allows for the use of fewer loudspeakers compared to speakers that have less consistent coverage control.

The large backcan on the Control 45C/T, along with the low-frequency driver design, provides extended bass response for a warm full-bodied tone. The system’s 5.25-inch woofer features a polypropylene cone and pure butyl- rubber surround for long life. The coaxially mounted 0.75-inch soft dome features ferro-fluid cooling for enhanced power handling and reduced power compression.
Ideal for small and large projects alike, the Control 45C/T is switchable for use as either an 8-ohm low-impedance speaker, or as part of a 70V/100V distributed loudspeaker system.

HARMAN’s JBL Professional Adds to Groundbreaking EON600 Portable PA Series with EON610 and EON612 Loudspeakers

LAS VEGAS, Nevada – Featuring advanced waveguide technology and the latest in transducer design, HARMAN’s JBL Professional is adding two new models to its EON600 Series portable PA loudspeakers: the EON610 10-inch 2-way loudspeaker and the EON612 12-inch 2-way loudspeaker. Along with the previously introduced EON615 loudspeaker, the EON610 and EON612 deliver high-end studio monitor quality sound in a rugged, lightweight design.

“Since its introduction in January, the EON615 has been extremely well-received and the addition of the EON610 and EON612 give today’s working musicians and sound providers modern, compact options for a portable sound system that offers truly unmatched sound quality,” said Andy Flint, Senior Manager, Portable PA Marketing, JBL Professional. “The EON600 Series represents a complete rethinking of how truly good an affordable, self-contained, portable PA system can be.”

The EON610 and EON612 feature built-in, 1000-watt power amplification, providing exceptional headroom for a variety of applications, from fixed PA to gigging bands. Custom JBL high- and low-frequency transducers deliver massive sound pressure levels with lower distortion throughout the frequency range.

The foundation of the EON600′s performance is a breakthrough approach to waveguide design, solving the inherent beaminess of conventional speaker systems that causes them to have a different frequency response off-axis than on-axis. JBL engineers examined the radiation characteristics of the EON’s high- and low-frequency drivers at 36 different points employing JBL’s exclusive, state-of-the-art measurement techniques, then designed individual waveguides for both components that control the sound radiation at the high frequencies, the crossover point, and at the low frequencies.

Special fluting is designed into the structure that guides the frequencies through the full range of the system, resulting in consistent response throughout its entire coverage pattern. The quality and consistency between on-axis and off-axis response delivers uniform coverage and high intelligibility, which means the EON600′s smooth, transparent sound is the same for the entire audience. These characteristics are the foundation of high-end studio monitor sound and are now available for the first time in a portable, affordable system.

Knowing that fine-tuning sound requires sophisticated yet convenient control, JBL engineers developed an iOS and Android supported interface to be paired with the Bluetooth Smart Ready 4.0 for controlling master volume, adjusting the 5-way, user-definable parametric EQ, and saving and recalling user presets. The interface controls EON’s onboard best-in-class 32-bit, 130 mHz, ultra-low power, audio DSP subsystem, so it’s fast and efficient with superb audio quality. Four strategically placed handles allow easy handling, indexed feet allow secure stacking, transportation and storage, and extra-strong enclosures ensure rugged reliability, a hallmark of all JBL products.

PRG Calls K2 Into Active Duty for National Memorial Day Concert

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.

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.”

LAS VEGAS, NEVADA – JUNE 2014: Danley Sound Labs, manufacturer of innovative loudspeakers and subwoofers that cleverly sidestep the trade-offs and constraints of conventional designs, will have its newest cutting-edge products on display (Booth C11711) and powered up (Demo Room N108) at InfoComm 2014, Las Vegas, Nevada from June 14 to June 20. Included will be:

• Danley’s SBH (Skinny Big Horn) Series of ultra-compact, column-shaped loudspeakers, which has been expanded to include several dispersal patterns and frequency ranges.
• Danley’s OS Series of fully-weatherized outdoor loudspeakers, which has been expanded to include a new wider beamwidth model and a new subwoofer model.
• Danley’s BC218 subwoofer, which marks an “all-time low” for the company (25Hz!).
• A LARES electronic sound enhancement system composed of Danley Nano loudspeakers, with special demonstrations by company president Mike Hedden on the trumpet.
• A range of Danley’s speakers from the mighty Jericho horns to the Compact Mini’s. Danley encourages all lovers of big sound – curious, converts, and skeptics alike – to come enjoy the Danley difference!

Unlike conventional designs, Danley’s SBH column loudspeakers are acoustically coupled to create a single large horn with an effective path length of over 25 feet. As a result, listeners enjoy an uncompromised frequency response at any listening position, and the output is free of troublesome lobes. Danley will have the SBH-10 (10-deg vertical), SBH-20 (20-deg vertical), and SBH-20LF (integrated subwoofer section for 40Hz performance) on hand. Hear for yourself.

Although most Danley products can be optionally weatherized, Danley’s OS Series is designed to endure unrelenting inclement conditions without compromising fidelity and performance – right out of the box. In addition to the original OS-80, Danley has added the OS-100, which has a 100-deg conical pattern and a smaller footprint than the OS-80, along with the OS-115LF, which delivers Danley’s famous low-frequency output. Show up and spill your drink on one.

In addition, Danley will demo its BC-218 subwoofer, which uses Tom Danley’s pioneering “Boundary Coherent” technology to deliver smooth, undistorted low end down to 25Hz (those in the EDM world take special note!).

And finally, lucky attendees will get to enjoy Mike Hedden’s sonorous trumpeting as amplified and spatialized through a LARES system composed of Danley’s diminutive (in stature, not in sound) Nano loudspeakers. Like most of what goes on at Danley Sound Labs, it has to be heard to be believed!

ABOUT DANLEY SOUND LABS Danley Sound Labs is the exclusive home of Tom Danley, one of the most innovative loudspeaker designers in the industry today and recognized worldwide as a pioneer for “outside the box” thinking in professional audio technology.
