The Cannstatter Wasen may well be one of the fairest of fairs and it is certainly among the world's biggest. Every year more than three million people come to enjoy a wealth of offerings extended by 320 exhibitors and caterers in and around the large beer tents.
The Göckelesmaier tent, a historic venue with a rich heritage, holds over 3,800 people in its main seating area and VIP boxes. Measuring 70 by 42 meters, it treats audience to culinary delights and varied entertainment. All kinds of events and live acts figure prominently on the stage, including performances by famous bands and artists.
A program as varied as this poses some daunting acoustical challenges. Stringent noise pollution regulations certainly do not make things easier. Soundline, a company from Untermeitingen, stepped up to develop and implement a very special solution for the tent.
The greatest challenge was satisfying the demands of the venue's operator while covering different zones within the tent. Although this does not sound like much of a feat, the situation was tricky. For one, the PA would have to provide uniform SPL and coverage all across the main seating area at very different volumes dictated by the level of crowd noise. The volume for the VIP boxes would have to be individually adjustable by the head waiters to cater to the wishes of the guests in the boxes. Finally, it all had to be incorporated into a noise management plan required by the operator to ensure that the volume outside the tent would not exceed a mean level of 80db (A). So a great deal of planning effort was required to keep from jeopardizing the tent's operating permit.
Once again, Soundline owner-operator Robert Reichle relied entirely on RCF to get the job done. Ease data are available for these systems. They were loaded to Ease and Ease Focus II to generate an accurate 3D simulation and compute the levels for the tent. The outcome provided the basis for the overall sound reinforcement plan, which was then submitted for approval.
"The fact that we had Ease data available for all TT + speakers (RCF Touring & Theatre Series) made it so much easier to prepare the sound reinforcement plan and put it into action. We have been thoroughly satisfied RCF users for years now, and I knew straightaway that we would be able to work out a suitable concept with RCF products," says Robert (Robby) Reichle.
Eight TTL33-A MKII enclosures were deployed for the front-of-house PA. Two TT1-A units served as a front-fill. Six each TTL31-A MKIIs covered the sides, and six TTS-56As and six TTS 36-As were configured in a cardioid set-up. The VIP boxes were equipped with TT08-As and TT052-As.
"It all worked wonderfully. I was very much looking forward to how the Stihl Timber Sports Event would work out with 70HP chainsaws roaring away while speakers the presenters spoke and music was piped in. My expectations, which were very high, were exceeded by a considerable margin," adds Robert with a smile.
Following a successful Sonar meeting in Malaysia last year, RCF recently hosted a two-day meeting in Bali for its distributors in the region. ‘We like to think that we’re a big family and feel that these meetings help to strengthen our relationships,’ explained RCF’s Asian Pacific sales manager, Lars Yoshiyama.
Distributors from as far afield as New Zealand and Japan came to Bali to better understand the latest RCF technologies and products, including the TT+, Media and Acustica loudspeakers, Ayra monitors, IPS amplifiers, Forum conferencing solutions, RDNet 2.0 software, together with the digital AX/MX matrix and DXT evacuation systems.
The new Livepad mixers on display at the Hotel Magani certainly took the eye of all those who attended. The four new models represent a new market for RCF and fill a much-needed gap in its product catalogue as a complete solution provider in addition to providing increased brand visibility. The aggressively priced LivePad mixers feature USB interfaces, three-band equalisers, 99 pre-sets, 4-6 microphone inputs in addition to an MP3 recorder, Bluetooth and Player cards.
‘By having full control of the signal chain, the LivePad mixers are compatible to our other products and are more dedicated to our speaker designs,’ commented sales director Alberto Ruozzi.
Mr Yoshiyama shed further light into the investment taken by RCF in hosting such an event. ‘Sales increased by over 30 per cent in the region last year, so we need to work more closely with our partners. You cannot really achieve that during a trade show such as Frankfurt Pro Light + Sound. On one hand, it is good for us as a manufacturer to spend two days explaining our products in greater detail, but on the other hand it is equally important for us to better understand how their markets work. At the same time, we encourage group discussions between different partners in a relaxed setting in which they can share their experiences and learn from one another. For example, some partners are stronger in the live than the fixed installation markets, so they can relate to one another and learn from each other’s experiences.’
Following the first day’s activities, the delegates spent the evening on a sunset cruise off the Bali coast.
"Nell'anno del Centenario del Festival lirico mi hanno invitato all'Arena per un'altra esperienza con l'orchestra... impossibile dire di no".
Con queste parole il rocker reggiano Luciano Ligabue ha calcato il palcoscenico più prestigioso d'Italia per sei magiche serate live. E per farlo ha scelto un compagno di viaggio non solo conterraneo, ma anche concittadino: RCF, l'azienda reggiana con sede a Mancasale (RE), che si è occupata di amplificare la musica del Liga per tutta la durata dell'evento scaligero, nella splendida cornice dell'Arena.
L'evento ha avuto inizio lunedì 16 settembre e, come c'era da aspettarsi, lo show è stato un vero trionfo. Il Liga sale sul palco assieme alla Simphony Orchestra diretta da Marco Sabiu e, dopo pochi minuti, anche la band si mette in primo piano assieme all'artista. L'impatto con il pubblico è immediato e la musica del Liga travolge l'arena.
"Il nostro obbiettivo è stato ampiamente raggiunto" spiegano i tecnici di RCF "abbiamo studiato a lungo come sviluppare la configurazione ideale che potesse far sì che la musica raggiungesse anche lo spettatore più lontano dal palcoscenico con la stessa energia, la stessa intensità e la stessa qualità audio."
Ognuno dei 64 elementi della Symphony Orchestra poteva vantare una straordinaria presenza sonora e tutti gli strumenti potevano essere distinti nei minimi dettagli con estrema chiarezza e precisione. Lo stesso discorso vale per la voce del Liga: distinta e chiara durante le canzoni e di estrema limpidezza e comprensibilità durante gli intermezzi di parlato.
RCF si è presentata in Arena con un Live Equipment di tutto rispetto e il risultato lo dimostra.
Per la copertura sonora del front field sono stati utilizzati due line array da 18 moduli TTL55-A e due line array da 8 TTL 36-AS, il tutto rinforzato da 18 subwoofers TTS56-A in configurazione cardioide. Inoltre, due array da 10 moduli TTL-55A sono stati dedicati alla copertura delle zone più laterali rispetto al palco e 6 moduli TTL 33-A, appoggiati al palcoscenico, contribuivano a dirigere il suono in direzione della platea. Per la copertura sonora sul palco sono stati scelti 3 moduli TTL33-A e 2 Sub TTS28-A per ogni lato. In più, 4 stage monitor TT45-SMA erano dedicati esclusivamente al monitoraggio per l'artista.
Il sistema principale e' stato controllato tramite RDNet, la rete proprietaria di RCF. "RDNet ci ha permesso di settare il sistema in brevissimo tempo" afferma un tecnico del suono di RCF "Mi sono spostato all'interno dell'arena con il mio laptop per dettare tutti i parametri e l'equalizzazione di ogni singolo speaker. In questo modo ho potuto compensare l'acustica dell'ambiente per realizzare una sonorità complessiva creata ad hoc per l'Arena".
This summer’s Ultra Europe Festival in Croatia saw a massive show of strength from RCF’s flagship TT+ line array system.
Zagreb-based production company, Promo Logistika provided a mighty 72 of the high premium TTL55-A and 42 TTS56 subs — more than enough muscle and rumble to satisfy the stream of international DJ’s performing on the main stage.
The global event itself took place in Europe for the first time over the first two days at the Poljud Stadium in Split, with 40 DJ’s appearing on three stages, before relocating to Hvar Island for the final VIP day with a single stage by the pool of the Hotel Amfora.
With 35,000 people attending each of the first two days, the event will now remain exclusively in Croatia for the next five years under the licence of Ultra Miami.
With wide experience in technical production for major events, concerts and festivals — such as Big Beach, Umagination and Discotheque Riva — Promo Logistika were entrusted with providing the technical infrastructure.
“We were very proud to be involved,” stated director, Zoran Biškupić, whose company was working under the technical supervision and guidelines of the Ultra Miami production director. “We proposed RCF to the technical director who immediately approved, and they were more than happy with how the system sounded.”
Promo Logistika has been steadily building up its RCF inventory over a four year period — but such was the requirement at this event that Audax Audio in Germany also assisted from their own stock.
The speakers were designed into two main L/R hangs of 18 TTL55-A, with eight further elements on each side of the stage as outfills. Two delay towers were set further down the field, each with ten TTL55-A enclosures. The subs were positioned in a straight line in pairs (at 2 meter distance) and were electronically curved through RDNet, in order to control the directivity and widen the coverage.
In addition, the DJ’s were well serviced with reference monitoring in the shape of four HDL 20-A’s and two HDL 18-AS subs per side.
In conclusion, Zoran said, “Everyone was satisfied with the sound, and the technical director told us the system delivered more than he had expected."
“For us the advantages of the TTL55-A were that the system was easy to assemble, it produced a really good output and offered great control through RDNet, RCF’s dedicated, integrated networking board."
“We were very proud to have been owners of this RCF sound system and since the event have been suggesting this solution to all our clients and partners who are engaged in holding large-scale events and festivals.”
As the largest football stadium in the German Bundesliga, with a capacity of over 80,000, Signal Iduna Park — home of Borussia Dortmund (BVB) — recently sanctioned a radical upgrade to its public address system. Their aim was to achieve higher intelligibility, even pattern control (with extended low frequency capability) and unobscured sightlines — but most importantly to link the voice evacuation and stand systems into a unified network, that could be monitored, error- and health-checked remotely. The solution was provided by RCF.

The deployment of 14 RCF clusters of 14 TTL33-A MKII line array elements (with a TTS26-A sub at the base of each), will futureproof the famous stadium for decades to come. But the most remarkable aspect is that this is an entirely active solution, wrapped around the beams to keep the sightlines intact. Loaded with RCF’s proprietary RDNet DSP and additional electronics for monitoring it is this inherent software that has been programmed to integrate the new PA/VA evacuation system — thereby fulfilling the EN 60849 standard for performance requirements.
In Hollywood, entrepreneurial brothers Jonnie and Mark Houston are reinventing the nightlife scene from bottle service nightclubs to cocktail-focused themed venues. They currently operate a number of nightspots including the Cuban rum bar-themed La Descarga, the atmospheric Paris-themed Pour Vous and the Hollywood Piano Bar. Their latest incarnation is No Vacancy (1727 Hudson Av., Los Angeles, California), paying homage to Old Hollywood with a historic renovation of what the bar once was – a Victorian period house built in the early 1900s. While other venue concepts have been inspired by trips abroad, No Vacancy is closer to the hearts of the twin brothers who grew up in the neighborhood.
“We restored the house as much as we could and brought it back to life with every little detail from the knobs to the antique wallpapers from the 1930s,” notes brother Mark in a recent interview. “The redesign and restoration was a history lesson of LA and its culture throughout the years. It feels like you walked into Old Hollywood with classic cocktails and old-school entertainment, incorporating a wire walked and tight rope act.”
When creating a club concept, the Houston brothers strive to create an experience. They reach out in their designs to provide a cultural sophistication creating, “a vibe and an experience,” says Houston, “which incorporates design, a great cocktail program and entertainment that take you out of your everyday life.” To accomplish the fusion of audio and architecture, they called on Los Angeles-based Solid Design Audio, who had worked with the twin brothers previously on their Pour Vous club. “This year the Houston brothers gave us a little more freedom to create a sound design to match what they felt would become their signature venue, and as a result ours as well,” says Solid Design Audio principal Phillip Jordan. “This is an install we can be proud of.” Jordan opted to integrate the small-profile RCF TT051A active speakers, coupled with the small footprint of the S8015 subwoofers which allowed them to easily conceal the speakers. “RCF’s excellent design quality appealed to the client and the TT Series product cannot be matched for sound quality at any size,” says Jordan speaking of the design consciousness of eliminating the unsightliness of loudspeakers in the venue while still providing the foreground audio ambience. “We wanted a surface mount speaker that with the low ceiling would not be visually obvious, but would still be intelligible and loud yet allow listeners to still be able to talk to each other.”
Jordan notes, “The TT051A with DSP processing can accommodate the veering styles of DJs and handle whatever you put through it. What is amazing about the TT051A is the 5 ½” two-way cabinet it able to produce frequencies down to 65 Hz.” And with the low-profile footprint of the S8015 (a 15” bass reflex subwoofer that’s only 12” high), “by cutting into the seating we were able to make the sub virtually disappear into the design and at the same time create an impressive warm punch".
The system design includes an Ashly 24.24 zone system with sequenced Furman ASD120 power distribution. Each zone can be sourced by four DJ input locations. And each area – outside, upstairs bar, downstairs bar and dance floor – can be controlled independently. Power distribution allows the bar manager to sequentially activate each zone dependent on the use of the venue on any given night. Solid Design Audio is a team of designers and sound engineers who have become known for their focus on quality, design, creativity and precision in their club designs. The Pour Vous project they completed last year was voted one of the 10 best new bars in the U.S. by the CNN Eatocracy blog site. Located in the center of the new cultural revolution for quality design in venues sweeping the country, the design and integration company is at the forefront of nightlife venue engineering.

The Hotel and Event Production Services division of AVI-SPL has recently added 52 of the RCF TT052a dual 5” active two-way speakers into their rental department portfolio. Citing the ultra-compact size and performance, the TT052a is the perfect solution to their truck pack case as they can easily fit six units plus pole mounts and other necessary audio gear in a 22 1/2”x30” total solution package.
“Six units is the magic number for our gigs,” notes AVI-SPL Director of Audio Mario Rivera at AVI-SPL's Tampa, Florida office. That meets the needs of their Event Production Services division, as the AVI-SPL philosophy is to work with clients to identify the best ways to design, implement and manage their messages. When it came time to search for an updated solution for their rental department, they included the RCF product in the evaluation process. “We were looking for something that sounded great, aesthetically was compact and clean and versatile” notes Wallace L. Johnson, VP of Operations. “I've been a fan of RCF for quite some time,” noted Rivera, commenting on his familiarity of the brand dating back to the 80s. While in the DJ and nightclub scene at that time, “I noticed venues using a lot of speaker products with RCF drivers,” recognizing the higher end component and quality. When he heard the TT052a, “I was floored by the depth and sound,” says Rivera. “Amazed by low end frequencies range, how clean and how musical they sounded versus the flat response of other boxes we looked at.” The ultra compact size (19.4”x5.9”x7.5”) of the TT052a lends itself to most of what AVI-SPL’s Hotel and Event Production Services division does – conferences and breakout room sessions. While many of those sessions are simply talking heads, “we wanted something where program material sounded good without needing to add a subwoofer,” says Rivera.
The TT052a is a two-way active wide dispersion speaker featuring two 5” woofers coupled with a 1” neodymium compression driver powered by a 300 watt class D amplifier with a frequency response 65Hz-20kHz. The wide angle 90-degree conical pattern makes audience coverage easy in a variety of situations. DSP on board processing offers a soft limiter, equalization adjustment, as well as thermal, excursion and RMS protection. AVI-SPL integrates the TT052a in a number of ways as they can be used for lip fill, center fill, laid on their side or on speaker stands. There is also a pipe clamp option available for truss mounting. In addition, “aesthetically they look nice. Our customers appreciate that,” noting how easily they seem to blend into the background.
For the second year in succession, RCF was chosen to support Japan’s Big Beach Festival (BBF) at the Makuhari Seaside Park in Chiba, which this year saw Norman Cook (Fatboy Slim) — who performed at the Festival back in 2011— and Basement Jaxx as headliners.
Promoted by Akira Kidoguchi and Masachika Fukui for A-life Entertainment Co. Ltd., rental company Comestock again equipped the three stages with premier active RCF TT+ Touring & Theatre systems to satisfy an audience totalling around 25,000 people.
But in addition to the usual armoury of high-powered TT+ line arrays there was a surprise for anyone visiting the party tent known as the ‘Disco Balloon’. Six of the new TTP5-A enclosures (three per side) were making their Japanese debut in the Balloon — supplied (as with all the RCF equipment) by the Italian manufacturer’s territorial distributors, Ballad Co. Ltd.
Dominated by its newly designed 4” compression driver, loaded on a dedicated waveguide to generate high power and pattern control, the system is designed to create horizontal or vertical arrays with a constant curvature. It derives its power and control from integrated two-channel 1600 Watt digital amplification and advanced digital processing.
RCF product specialist, Oscar Mora provided technical support — assisting with flying the rig, during rehearsal and at the event itself, as well as advising on cabling issues and which crossover points the TTS56-A and TTL36-AS required. In a system tech role, he also demonstrated correct use of the RDNet software to ensure the TT+ systems were fully optimised and monitored.
Comestock dug deep into their RCF inventory to provide superior sound coverage. The main stage saw 28 x TTL55-A enclosures, rigged in two hangs, reinforced by 12 x TTS56-A subs and 12 x TTL36-AS flyable bass, with a further 8 x TTL31-A provided for infill/nearfield coverage. DJ’s received their reference sound from an additional pair each of TT25-SMA monitors and TTS18-A subs.
The second Island Stage saw 12 x TTL33-A elements, with four each of the TTS28-A and TTL36-AS providing LF extension. A pair of TT25-A and four NX15-SMA were provided for DJ monitoring.
Finally, providing LF extension to the six TTP5-A enclosures in the Disco Balloon were a pair of RCF’s recently launched SUB 8006-AS, with DJ reference in the shape of the versatile TT22-A active, non-linear monitors.
During the event there was a lottery for two pairs of white RCF Ayra 5 studio monitors signed by Norman Cook. Left to right: Yuka Onda (Ballad, marketing), Oscar Mora (RCF, tech support), RCF’s Lars Yoshiyama, Norman Cook, Ou Lifeng (Ballad, admin)
Norman Cook was happy to be working in an RCF TT+ environment again, having previously used the TTL55-A at a beach concert in Croatia in 2011, while front-of house, sound engineer Shan Hira (who has worked with premier dance music specialists such as Basement Jaxx and Chemical Bros) was also more than happy with the impact created by the RCF system.
Tasked with managing the strategic planning of RCF in the Japanese market, Lars Yoshiyama, also added his endorsement to the successful deployment — noting how well the new TTP-5A acquitted itself, and the punch of the 4” CD driver.
Bangor Aurora Aquatic & Leisure Complex, the new leisure complex in the heart of Bangor, which houses Northern Ireland’s first FINA standard 50 metre swimming pool, also boasts an advanced and adaptable site-wide RCF communication network.
This was installed across 15 zones, each with its own autonomy, by MGA Communication Ltd, and features well over 200 application-specific loudspeakers from RCF to meet all audio and PA/VA requirements. These are driven either by low-impedance HPS1500 amps with PR4092 preamps or 100V line UP2162 (160W) or UP2321 (320W) 100V line amps with ES3160 ‘combi’ mixer amps — all in dedicated local racks.
Managing Director, Gerald McKeown said that the system was complex, but is designed to provide high-end sound broadcast throughout both internal and external areas, with user flexibility and ease of operation.
The speakers are fed from a central distribution hub, based around RCF’s powerful DXT7000 management system, from which two further pools, health and fitness suites, multi-discipline sports hall, squash courts, crèche, function rooms and cafeteria all receive distributed sound. Three external 3G synthetic training pitches are served by local IP67 rated cabinets, heat and environmentally protected, to contain the RCF amps, receivers and CD preamps.
Built with the aid of the Department of Culture, Arts and Leisure (DCAL), the new leisure complex was formally opened at the end of March.
MGA had been introduced to the project by JCP Consulting whose senior electrical engineer, Ivan Humphries had detailed the project requirement and the system parameters required. The 20-year old integration company, based ten miles south of Belfast, won a competitive tender and also provided IPTV / Video Wall and IP telephony in addition to the RCF solution.
“We needed qualitative and flexible sound reinforcement throughout the building, and if there was a single portfolio I could draw on, so much the better,” Gerald rationalised.
All communication systems deployed throughout the complex were under the control of the Project Director, Aaron McKeown, who attended many meetings to ensure that issues were resolved, while the company’s senior site engineer likewise ensured that installation was carried out seamlessly to a high standard.
RCF’s Audio Systems Consultant, Daniele Torelli, proposed a flexible design offering a high degree of control, efficiency and adaptability, based on his EASE predictive modelling.
The beating heart is the DXT7000’s pair of EN54-16 compliant MU7100 digital matrix devices in the central rack room. These feed a combination of 100V line and low-impedance amplifiers in 14 satellite racks, to ensure a high end broadcast signal was distributed to what ended up effectively being 24 zoned areas.
The entire signal path from the system microphone to loudspeaker lines is automatically monitored against faults. All properties and functions of the system are specified with Windows® based DXT 7000 configuration software and are downloaded to the ‘master’ unit through its USB port.
These powerful units incorporate 8-channel high pass filter, 8-channel para EQ in output, digital delay, 8ch comp/limiter and 8 x 80W digital amplifiers — some of which feed the peripheral areas and RCF’s BM7624D 24-zone paging mic station at front reception.
“The advantage is that zones can be reprogrammed and new zones added,” states Gerald, “while the provision of Cat5/Cat6 cable means that the entire system can be monitored and healthchecked.”
Of all the zones, the major challenge facing the installers was optimising the acoustically harsh Olympic-sized pool, on the one hand avoiding slapback from the rear of the audience area while delivering high intelligibility at poolside — all the while retaining the architectural aesthetic.
They specified 16 weatherproof and chemically-protected RCF Acustica P3115T . These 15in coaxial 90° x 60° IP55-rated wide dispersion speakers are mounted in 3 x 4 and 2 x 2 clusters overhead along the existing trunking. Using stainless steel grilles, these provide uniform coverage of speech, gala announcements or background/foreground music and have been tuned to reduce level firing back from the audience of the glass walls encasing the pool, thus neutralising reverberance.
These same speakers are also used in multiples to provide distributed coverage of all the synthetic sports pitches, while elsewhere Acustica C3108 ’s also enjoy heavy usage. From the foyer to the car park to the general public areas, RCF have a speaker for each purpose.
The facility is managed by Serco Leisure Northern Community Leisure Trust, a partnership between Serco Leisure Operating Ltd and North Down Borough Council.
Their technical manager, Lee Cattle, pronounced that he was “delighted” with the technological integration and the high intelligibility offered by the various RCF components. “The whole communications system is functioning extremely well,”he confirmed.
Gerald McKeown added, “It met all our expectations and possibly more,” adding with satisfaction comments from the management company that they had rarely seen such a professionally installed and adaptable networked sound system.
