Radio Active Designs Introduces SPX-1 Professional Headset

The new SPX-1 headset from Radio Active Designs (RAD) is ultra-lightweight for supreme comfort while featuring a rugged nylon body and heavy-duty construction ideal for busy professionals.

“This headset works great with our RAD belt packs in any environment but particularly during events that have extremely high noise levels,” explain James Stoffo, CTO, RAD. “Communications during music awards shows, concerts and sporting events can be extremely challenging due to high SPL. This headset has exceptional audio isolation, so you don’t have to worry about missing anything.”

The SPX-1 features a flexible, dynamic microphone that can be configured for left or right ear use. The dynamic speaker unit offers an impedance of 200 Ω, frequency response of 150-6,000Hz, and SPL of 106 dB. A convenient flip-up boom switch automatically turns the microphone “on” when in the horizontal position and “off” when vertical.

The RAD design team, with more than 100 years of combined experience in RF, worked diligently to create a headset that would not only offer optimal audio quality, but also be reliable and durable enough for the toughest applications. The SPX-1 is the result of their efforts.

“I have used a number of different headsets during my 35+ years in the industry,” concludes Stoffo. “I was always searching for something lightweight, LOUD, and reliable. I found I had to settle for two out of three. The SPX-1 hits all three without exception.”

CP Communications Taps RAD Intercoms For Flawless Super Bowl LIII

Atlanta, Georgia (February 2019) – Communication during sporting extravaganzas like Super Bowl LIII is always difficult, taking places in congested cities that are typically “RF challenged”. This year’s Super Bowl in Atlanta was no exception. Fortunately, Radio Active Designs (RAD) UV-1G wireless intercom systems were in use during numerous events leading up to, during and after the game to ensure all lines of communication were kept open.

CP Communications, located in Wappingers Falls, New York, was responsible for wireless audio transmission for pre- and post-game events handled by the NFL Network, CBS Sports and ESPN. The company provided nine UV-1G base stations along with 40 RAD bodypacks to ensure production went off without a hitch.

“Our clients covered everything all week long – starting with opening night and ending with post game ceremonies and shows,” explains Michael Mason, president CP Communications. “When we were in planning mode it was clear that the most available spectrum would be VHF, which is where the RAD units primarily operate. The RAD wireless intercom was the right tool for the right job, hands down.”

Radio Active Designs’ UV-1G wireless intercom system features body packs that operate in the VHF band, freeing up valuable space for wireless systems that require limited UHF bandwidth. The unit features Enhanced Narrow Band technology, which is 10 times more spectrally efficient than current FM technology. As a result, the UV-1G offers RF channels possessing an occupied bandwidth of a mere 25 kHz the audio characteristics one would expect from a traditional FM system. The system offers seamless roaming for 600 meters with body packs that provide loud and clear audio even at the extreme end of the range, an exceptional solution for large events like the Super Bowl.

“Another advantage to the RAD gear is that you can more easily move it around with proper coordination as the spectrum is more available,” Mason adds. “We had drop down units that were moved to different locations throughout the week leading up to the game and we had no problems with other RF in the area.”

Recent upgrades to the system were another bonus for the CP Communications team. Scene Change feature allows each pack to have up to 40 talk paths and communicate with 20 wired comm channels. Base Linking affords matrix like functionality with up to 18 inputs/24 outputs and comprehensive audio routing to/from packs. Users can easily change belt pack parameters including radio frequencies, button assignment, talk paths, and audio channel via software with intuitive UI. All these features were put to use during game day in Atlanta.

“Given the scope of an event like the Super Bowl, it is understandable that there are limitations to what technology can be used,” concludes Mason. “It is nice to have wireless solutions like the RAD intercoms that you know are reliable and will get the job done.”

Professional Wireless Teams Up With Radio Active Designs To Deliver RF Training During AES@NAMM

Anaheim, CA (January 2018) – Wireless touring professional Ike Zimbel will provide introduction and training for both Professional Wireless IAS software and the Radio Active Designs UV-1G wireless intercom system during AES@NAMM. The two-hour training sessions are part of the Entertainment Wireless Academy sessions offered during AES@NAMM and will take place on Thursday January 25, 1-3 pm and Friday, January 26, 3-5 pm at the Anaheim Hilton.

Zimbel explain, “Professional Wireless’ Intermodulation Analysis System (IAS) software if the industry standard frequency coordination software that has been used on every major sporting and broadcast event since its inception.” The interactive session will cover the entire program including finding local off-air TV channels and importing your own scan, band planning, recalculating a coordination when moving between venues and tips and tricks to deal with very high channel count events.

In addition, Zimbel will take participants through the Radio Active Designs UV-1G wireless intercom system from base station to belt pack. Topics covered will include Analog RF transmission scheme, best practices for set-up and deployment, using the GUI to program bases and belts, “Scene” memory in belt packs and why the UV-1G makes the most sense for your intercom inventory.

“Available UHF bandwidth is being reduced to just (at most) 150MHz from the current 222MHz, making spectral efficiency of paramount importance,” adds Zimbel. “With the very small footprint of the UV-1G UHF transmit frequencies and the fact that the belt packs operate in the relatively open VHF band (also with a very small RF footprint), the UV-1G is the best choice for large intercom intensive events, small “dry hire” rentals and everything in between.”

Zimbel will also present two 30-minute “Professional Wireless Antennas Types & Design” sessions that will walk attendees through the range of antennas and antenna accessories made by Professional Wireless Systems. Attendees will leave understanding how upgrading antenna systems can upgrade their wireless game. These sessions will be held from 4:30 – 5:00 pm on both Thursday, January 25 and Saturday, January 27.

RAD Provides Seamless Communications For 18th Annual Latin Grammy Awards

Las Vegas, NV (December 2017) – Latin music superstars Jaime Camil and Roselyn Sanchez recently hosted the 18th Annual Latin Grammy Awards held at the Grand Garden Arena at the MGM Grand Hotel & Casino in Las Vegas. The event, which was broadcast live on the Univision Network, utilized Radio Active Designs (RAD) UV-1G wireless intercoms to facilitate communications.

New Jersey-based Professional Wireless Systems (PWS) provided 50 RAD packs and eight UV-1G Base Stations that were managed by RF Intercom Technician Gary Trenda. RF Technician Jason Lambert was responsible for system integration between both inside and outside of the venue, while Jordan Smith managed distribution of all the wireless intercom and related equipment throughout the event.

“RAD’s systems were used across four coverage zones,” explains Trenda. “Because the RAD base stations minimize their footprint in the UHF spectrum and the body packs transmit in the VHF range, we used as many of the RADs as we could. It is the most spectrally efficient UHF intercom product and very straightforward to deploy.”

The UV-1G wireless intercom system is unique because the body packs operate in the VHF range, where there is plenty of available spectrum to use. The base station utilizes proprietary Enhanced Narrow Band technology which allows the 6-channel unit to occupy a mere 25 kHz of RF bandwidth while maintaining the audio characteristics one would expect from a traditional FM system.

“This years event covered a lot of ground, literally,” concludes Trenda. “It was terrific to have a product as reliable and stable as RAD for communications. It made is much simpler to coordinate the rest of the RF for the show.”

14th Annual Premios Juventud Bets On The Future With Radio Active Designs

Coral Gables, Florida (August 2017) –  The 14th Annual Premios Juventud Awards Show, presented by Univision, recently took place at the Watsco Center in Coral Gables, Florida. Show communication was aided by Radio Active Designs (RAD) wireless intercom systems provided by Orlando, Florida-based Professional Wireless Systems (PWS).

The theme for the show, “Betting on the Future”, awarded some of the biggest stars in Latin music and featured performances from celebrities such as Enrique Iglesias, Carlos Rivera, Gianluca Vacchi, J Balvin and Iggy Azalea. PWS was on site to provide all wireless systems as well as system design, RF coordination, and support for the event.

“Because we were using over 200 wireless frequencies, it was critical to maximize spectral efficiency whenever possible,” explains Gary Trenda, RF Technician for PWS. “In this case, deploying seven RAD UV-1G wireless intercom systems, including 42 RAD belt packs, was a huge help.”

The UV1-G base stations are unique in that they operate in a very small slice of the UHF spectrum while the body packs operate solely in the VHF realm – freeing up considerable RF bandwidth for use by other wireless systems. The base station utilizes RAD’s proprietary Enhanced Narrow Band technology which allows the 6-channel unit to occupy a mere 25 kHz of RF bandwidth while maintaining the audio characteristics one would expect from a traditional FM system. The intercoms helped strengthen communication between the producers, stage managers, floor managers, and members of the rigging crew.

“In the past, we have used fewer RAD base stations, but this year we made a move up to seven systems as part of our transition away from UHF intercom systems, particularly UHF systems that operate in the 600 MHz range,” explains Trenda. “We have always been pleased with the RAD intercoms but recent firmware updates have improved audio quality, making these systems even better.”

To provide full coverage of the event, PWS created two zones, one covering the main stage/bowl and the other covering the backstage, production offices, and truck dock. They used a VHF distributed antenna system with a PWS DB-VIC 4-zone VHF intercom Rx multi-coupler to ensure seamless communications from one zone to the next.

Trenda concludes, “It’s already a challenge to coordinate in the 600MHz band – RAD UV-1G systems are extremely reliable and provide the frequency relief we needed. We had no problems maintaining two zones of RF coverage throughout the event – it was seamless.”

Progressive Field Revamps Communication with Radio Active Designs

Cleveland, Ohio (June 2017) — Progressive Field, home to Major League Baseball’s Cleveland Indians, has recently undergone a system upgrade that includes the installation of two Radio Active Designs UV-1G wireless intercom systems.

Michael Ramirez, the stadium’s audio-video engineer, added two UV-1G base stations and 12 RAD packs to improve communications for game day staff – which includes camera operators, advance team coordinators, mascot coordinators, on-field anthem singers, and others involved in game day production.

“We needed a system that didn’t operate in 2.4 GHz – which was allocated for stadium Wi-Fi – and that would provide the clarity of an analog signal,” explains Ramirez.  “Because RAD is analog and operates primarily in the VHF band, it seemed like the obvious choice. After presenting the most consistent results of all the systems tested, it was an easy decision. Knowing frequencies would change in the future and that we were adding Wi-Fi to the building, the UV-1G was our best bet.”

The base stations are rack-mounted in the scoreboard rack room located behind home plate, providing exceptional coverage in the stadium bowl. When systems are utilized outside of the park Ramirez deploys an antenna to extend that coverage beyond the dense concrete walls of the stadium.

“It’s an older park with lots of cement, so getting any signal outside of the park is impossible,” adds Ramirez. “Fortunately, one antenna does the trick, which makes using the systems beyond the stadium walls very convenient.”

With UHF at a premium, it was important that the intercom system take up minimal RF bandwidth. As luck would have it, the UV-1G base station requires less than 30 kHz of the UHF band and the RAD packs operate completely in VHF. This made keeping valuable UHF bandwidth open for other wireless devices to operate easier.  As an added benefit, since the VHF band is virtually empty, every comm operator has their own channel, eliminating issues that can occur when forced to “double-up”, which is necessary with some bandwidth-challenged UHF systems.

With last year being the first season the UV-1G was in use, Ramirez has nothing but good things to say about the system at the start of this year’s season. “We have not had any issues, beyond normal wear and tear. The system is solid. The RAD systems work really well and were easy to integrate with systems we already had in place. We have accomplished exactly what we set out to and I’m quite pleased with the end result.”

Radio Active Designs Announces Upgrades For UV-1G Wireless Intercom Systems

East Rutherford, NJ (May 2017) – James Stoffo, CTO of Radio Active Designs, has announced the availability of a firmware update for the UV-1G base station and the RAD body packs. The firmware updates, which are available on Radio Active Designs website, combine to provide users with superior audio quality.

“After the updates are complete, the system has more headroom and offers a level of audio quality not available with any wireless intercom on the market now,” explains Stoffo. “The headset output offers greater gain and more dynamic range than before. It is a considerable improvement.”

The company has also introduced a Version 2 of the RAD Pack that not only provides greater battery life and a reduction in overall temperature but also offers headset microphone bias voltage to support use of any headset. Stoffo notes, “When we started working on the firmware we decided to incorporate a few extras in the next bodypack version as well. The package is now complete – our customers are very happy.”

This announcement comes on the heels of the FCC’s rollout of TV Repack channels after the 600 MHz auction. Once implemented, which could be as soon as three months, there will be a severe reduction in the quantity of UHF channels available for wireless.

“We created the UV-1G a few years back when the FCC started talking about the auction,” adds Stoffo. “It was clear it would dramatically alter the landscape of RF for wireless – and it has. One of the reasons we decided to design an analog system that operates primarily in the VHF realm was to move out of a crowded spectrum into one with more elbow room to make life easier for RF coordinators everywhere. Reliability is key in communications. Considering the changes that are heading our way, the UV-1G wireless intercom is the most dependable system on the market.”

CMA Music Festival Celebrates With Radio Active Designs

Four Radio Active Designs’ (RAD) UV-1G wireless intercom systems provided rock solid communications for the Nissan Stadium stage during the recent CMA Music Festival in Nashville. With several country acts performing every day of the four-day festival, communication between stage managers and audio, lighting and video techs throughout the stadium was of extreme importance.

Sound Image’s Nashville office once again provided sound reinforcement for the festival – they have worked with the CMA Music Festival since 2013. The sound company tapped Jason Glass (Clean Wireless Audio LLC) to handle the responsibilities of radio frequency supervisor, coordinator and technician for the festival. A long-time user of the UV-1G wireless intercom system, he was delighted the Radio Active Design units were on hand for the event.

“The UV-1G belt pack’s use of the sparsely occupied VHF-TV band is extremely helpful when you’re coordinating approximately 250 frequencies n the UHF-TV band for each day of the festival,” Glass explains. “The base station’s wide tuning bandwidth in the UHF portion of its transmission scheme is also beneficial, since you’re not bound to small blocks of tuning range but rather can tune anywhere within the UHF-TV band.

“Having narrow occupied bandwidths for each UV-1G frequency channel allows the user to pack more discrete channels into less spectrum than previous RFPL technologies, and having six belt pack drops per base station allows larger system deployments with less hardware in the PL racks.”

Each year at the CMA Festival an antenna truss is deployed high above the stage which includes an omnidirectional ground-plane antenna to receive intercom belt pack transmission over a wide coverage area in the stadium. Those signal are then fed to the UV-1G base stations’ antenna splitter through 125 feet of low-loss coaxial cable.

“UHF signals would attenuate 4.3dB at 470MHz to 5.2dB at 698MHz (this is the full UHF-TV range) through these cables, while VHF signals attenuate roughly 2.7dB,” continues Glass. “The difference is just under twice the transmitted power through the line. This allows larger roaming range for these systems and more reliable links from belt packs to base stations without the need to resort to noisy active RF amplifiers to drive long cables.”

Sound image subcontracted CP Communications to provide intercom gear, which included the four UV-1G base stations and 20 RAD packs. Tim Kepner, intercom design and lead engineer (TLK Audio Video Services), worked with both Sound Image and TV Broadcast to provide them with an integrated comms design and implementation that would simultaneously flow well for both the live and broadcast portions of the show.

Kepner was responsible for all in house intercom and integration to broadcast facilities during the festival. Having used the UV-1G system in equally challenging RF environments before – the Pope’s visit this past year, Made In America, Univision Latin Grammys, Premio Juventud and Premio Nuestro shows, to name a few – he knew they were up to the task.

“One of the nice things about the UV-1G is that the feature set is familiar to non-technical production oriented operators so they can adapt to it very easily,” he explains. “The setup is also very straightforward with the added bonus of being able to program the devices on a PC, without having the systems on hand. When I get to the venue, I plug in my computer and dump the settings into them. If I have to make any fast changes to settings on the hardware, it’s relatively simple to navigate the menu and make it happen.”

The four UV-1G base stations were rack mounted on stage by the monitor mix area with 20 RAD packs in use throughout the festival. Radio Active Designs’ Enhanced Narrow Band technology provides each channel of the UV-1G with an occupied bandwidth of only 25 kHz – substantially less than a typical system. The RAD packs utilize the relatively unused VHF range for all belt pack portable devices. The combined result is more available RF for operation of other wireless devices which are in high demand.

More than 65,000 country music fans were drawn to the musicians performing at the Nissan Stadium which included Rascal Flatts, Jason Aldean, Carrie Underwood, Blake Shelton and Luke Bryan. Kepner adds, “This was the 45th anniversary of the festival and it broke all attendance records. That speaks volumes about the experience fans have during the event. Keeping lines of communication open is important and the RAD UV-1G was integral to making that happen.”

Radio Active Designs Aids Communication During Beyoncé Tour

Highland Heights, Ohio-based Eighth Day Sound provided a Radio Active Designs (RAD) UV-1G wireless intercom base station and 12 RAD packs along with sound reinforcement and production support for the recent Beyoncé “On The Run” tour.

“The belt packs were used by lighting, video, audio and carpenter departments as well as by the stage manager and production manager,” explains System Tech Christopher Bellam. “The base station was located in a rack with the other wireless RF and hardware gear back stage. The system worked extremely well and sounded great.”

The RAD UV-1G is unique because the 6-channel unit utilizes a small amount of UHF bandwidth – only 25kHz per channel – while the RAD packs operate in the seldom-used VHF range. This opens up valuable RF space for wireless microphone and in-ear monitoring systems. Tour RF Tech Corey Willis, who was responsible for 36 channels of RF and IEM coordination, found the additional bandwidth incredibly useful during production.

“This was my first experience coordinating wireless COM and with zero experience, I was able to set up RAD and have it programmed and ready to use the first day we had it,” adds Bellam. “The software is very intuitive and their customer support was terrific. The production and stage managers were extremely pleased with the system.”

Radio Active Designs Kicks Off NFL Football Season

Valencia, California-based ATK Versacom recently provided audio and video production for the annual NFL pregame concert held in San Francisco. The event went off without a hitch due in part to the three Radio Active Designs UV-1G wireless intercom base stations and 18 RAD belt packs utilized to keep lines of communication open for the crew.

In past years the concert was hosted by the previous Super Bowl champions, but this year the concert was held near the historic Ferry Building in downtown San Francisco as part of the celebration for Super Bowl 50. Train and Ellie Goulding headlined the event.

The concert was also the debut of Radio Active Designs UV-1G wireless intercom with newly introduced enhancements that included a new audio board along with Base Link and system synchronization technology.

“The enhanced version represents a vast improvement in audio quality,” explains ATK Versacom’s Matt Campisi, intercom system engineer for the event. “In addition, the system delivers much higher audio levels which are incredibly useful in noisy environments like live concerts and football games.”

Even with the loud roars of the audience and a concert level PA system, the UV-1G delivered loud and clear communications for the backstage audio and video crews. In addition, because the UV-1G system is the only professional wireless systems that operates in the relatively unused VHF band, frequency coordination was much easier.

“Thanks to all of the belt packs operating in VHF, there were more RF channels available for wireless and IEM,” adds Campisi. “This was the easiest NFL Kick Off concert that I have ever done from an RF coordination standpoint.”

Enhanced Narrow Band technology allows Radio Active Designs to fits more than ten times the amount of wireless systems in the same band as FM systems. As a result, even the base stations, which operate in UHF, have a very small footprint in the UHF band.

“Because Radio Active Designs is implementing split UHF/VHF technology, I could use up to 200 belt packs and thirty base stations in the same UHF footprint as one four drop FM system,” adds Campisi. “It sounds great, features 6 RAD packs per station, gets loud and frees up RF channels needed for wireless? It doesn’t make sense to use anything else.”
