When the Stamford Corn Exchange Theatre in Lincolnshire took the decision to invest in a permanently installed active line array system for its 399-seat auditorium, it opted for an RCF HDL10-A from locally based LUX Technical.
The Theatre, which was built within the shell of the original Corn Exchange Hall in the Victorian era, needed a versatile system to handle its varied programme ranging from stand-up comedy to local am-dram and full blown rock concerts. LUX Technical bid successfully for the contract which was issued by Theatre Manager Judith Mackie. Having experience LUX Technical’s larger HDL20-A rental system on many occasions, her team had been fully aware of the system’s coverage capabilities.
“We decided to install a permanent system because when touring companies arrive with their own production they often carry enormous speakers. We wanted to make it easier and quicker to load in and load out by providing a flexible house system and encourage them to play through that,” she said.
And it has clearly been working, as according to the Corn Exchange’s assistant tech, Jack Milligan, “Everyone who has heard the speakers says what a difference they have made — they sound absolutely brilliant.”
The Theatre also needed to achieve best value as it is run almost entirely by volunteers, and since the start of the new millennium has been administered under a charitable company (Corn Exchange Theatre Company) — set up to support the arts in Stamford.
The journey to discover the best solution had been driven largely by the Corn Exchange Theatre’s technical director Roger Bradshaw. In conjunction with technical manager, Robert Mackie they evaluated a ground-stacked version of RCF’s popular D-Line series and gave it the thumbs up.
With its onboard 1400 Watt Peak Power 2-way digital amplifier and powerful DSP, the HDL10-A not only met the criteria — but also provided a more manageable and less obtrusive piece of real estate to fly over the proscenium arch. Three HDL10-A elements have been hung each side along with an HDL15-AS flyable sub.
Providing front row infills are a pair of RCF’s TT052-A. Equipped with two 5” neodymium woofers and a 1” compression driver, these are ideal where the audio beam needs be directed towards a specific area, such as the front row seating.
According to LUX Technical’s managing director, Peter Gibbons, his company has been a fan of RCF’s D-Line composite line arrays since taking over Stewart Duckworth’s Chameleon Pro Audio & Lighting Ltd (who had been first UK customer for the HDL20-A).
“We have done many shows with the HDL20-A but the smaller HDL10-A is also a super system, offering flexibility and great value for money. We were confident in this solution and it has fitted perfectly into the acoustic space, and packs a real punch.
“It’s a nice and easy system to install and operate, with the flying hardware and the advantage of being able to fly the sub; it’s also very lightweight considering it has all the amps on board. Overall, it’s a superb piece of kit.”
The HDL10-A rig is the centrepiece of a larger audio fit-out and Peter Gibbons observes that because it is a modular system, when additional bass is required, the theatre can simply add a couple of additional HDL matched subs from LUX Technical’s hire stock.
When RCF’s project team first arrived in Azerbaijan, in November 2014, construction work on the new stadium was already at an advanced stage. With a capacity of 68,000 spectators, and characterized by remarkable architecture, Baku Olympic Stadium was positioned to become one of the landmarks of Azerbaijan’s capital city, with a population of 2 million. It was officially inaugurated in March 2015 and it will host the inaugural European Games in June.
RCF’s Engineering Support Group (ESG) and R&D Department had worked together with the local distributor Asimetrik during the previous year, in order to develop the best acoustic solution for the venue. After the final approval and a Factory Acceptance Test in April 2014, with the main contractor, subcontractor and local distributor visiting RCF’s production facilities in Italy, official installation of the system started with the team’s first trip to Baku in November 2014.
“We used as many as 270 customized units of TTL55-A for 1 MW of audio power. This is one of the biggest permanent installations we have undertaken so far,” RCF explains. “It was a very stimulating project because our standard TTL55-A active 3-way line arrays had to be adjusted and customized, particularly in respect of their mechanic and electronic system”. Thanks to the significant expertise developed with previous experiences, such as Signal Iduna Park in Dortmund and other international stadia, the team rose to the challenge. “We made a few visits to Baku and provided some specific instructions for the set-up. The whole installation process was supervised remotely from our headquarters through RD Net,” adds RCF with obvious satisfaction.
TTL55-A modules were chosen due to their familiar vocal clarity and high SPL of more than 120 dB. These were two of the contractor’s main requirements for the system, because part of the audience is seated as far as 63 metres from the speakers. The final configuration is composed of 20 clusters, delivering excellent sound to all the tribunes (10 clusters containing 17 cabinets and 10 clusters with 10 cabinets, for a total of 270 cabinets).
An active line array was the right choice for this project because it allows very simple and discreet wiring, with only two signal cables – one for the audio signal and the other for the digital control system. Despite its imposing size, the system’s cabling is clean and easy to manage.
The overall acoustical design of the Stadium includes 64 units of P2110 (10’’ coaxial two-way speakers) for the under balcony area and 12 units of H1315 (3-way horn-loaded bi-amped mid throw cabinets) for the playing area.
The use of standard fly-bars was excluded from the beginning and a special frame was fabricated instead. The aim was to create line arrays flown parallel to the ground, ensuring perfect sound coverage to the whole audience when the cabinets are placed above the tribune.
“We drew a lot on the experience gained from Dortmund,” RCF states. A special frame composed of stainless steel mounting hardware and internal bracing with 16 lateral fixing points, suitable for the overhead configuration, was designed by a German engineering company. All TTL55-A cabinets were customized by RCF with metal backbones and internal supports for additional safety, making sure that the line array’s weight is safely supported by the steel structure and not just by the cabinets’ plywood.
Each single cluster is easily accessible thanks to independent motors, capable of lowering the frame at the tribune level. Once up in the roof position, each frame is secured to the roof structure through dedicated hooks and steel links.
The acoustical system in Baku Olympic Stadium has to withstand outdoor conditions 365 days a year. Hence all cabinets were processed with a special weatherproofing treatment consisting of external and internal polyurea finish and use of stainless steel for the mounting hardware and frame. Loudspeakers are reinforced with a special waterproof film and a multi-layer coating on the grille, highly resistant to humidity but transparent to sound.
RCF’s ESG and R&D Department together with Asimetrik developed a tailor-made solution allowing full monitoring of the system, making control, set-up and maintenance as simple and convenient as possible despite the large site. Each TTL55-A module is equipped with a sophisticated fault-monitoring board and reporting occurs through the RD Net control system.
The RD Net GUI (Graphic User Interface) allows a straightforward oversight of the whole system, including transducers, amplifiers, power supply and the whole audio connection path. The additional GPIO unit (General Purpose Input/Output) communicates any incongruity from the desired settings in terms of safety and acoustical performance. It sends an overall full and centralized report from a single station to any third party system. When a fault signal appears, it can be easily inspected through the RD Net GUI on the dedicated personal computer.
“Baku Olympic Stadium exceeded the customer’s expectations in many ways, not only in terms of excellent intelligibility, even when the stadium is empty, but also for the system’s high SPL and its distribution, designed to be in compliance with the latest international legislation. Moreover, the audio system fulfills all requirements of the EN 60849 standard for the electro-acoustic systems applied to emergency services, another area of long-standing expertise for RCF. Now we can’t wait for the European Games in June,” team members claim.
Come ogni anno il 1 maggio porta con sé una miriade di eventi musicali grandi e piccoli in tutta la penisola. Giunto ormai alla terza edizione, il concerto di Taranto è uno dei maggiori spettacoli di quella data, che ha radunato oltre 100 mila persone attorno al palco situato all’interno del Parco Archeologico delle Mura Greche, per uno show iniziato alle 2 di pomeriggio e durato ben dodici ore.
L’impianto audio firmato RCF è stato costituito da 12 moduli di TTL55-A a ogni lato del palco, affiancati da ulteriori 6 moduli per lato come side-fill. La riproduzione delle basse frequenze è stata gestita attraverso 18 subwoofer TTS56-A, ideali per spazi molto ampi, con configurazione in straight line cardioide e curvati virtualmente.
Il team della rental company Provinciali srl è stato sul posto per il set-up del sistema e durante l’intero concerto. Il responsabile tecnico Pierluigi Provinciali ha saputo garantire un perfetto svolgimento dello show insieme ai collaboratori Luca Scornavacca, Simone Losito e altri. “Dal punto di vista acustico la peculiarità di questa installazione è data dalla dimensione dell’area” spiega. “Si tratta di un parco davvero vasto, perciò abbiamo esteso la copertura con linee di ritardo che hanno compreso tutta l’area sul piano orizzontale, garantendo un’ottima qualità dell’audio anche sui lati e non solo al centro.” Le linee di ritardo erano costituite da 4 cluster di 6 TTL55-A ciascuno, per estendere la copertura fino alla distanza di 150 metri.
Un ulteriore fattore di criticità che ha caratterizzato l’installazione è l’inusuale collocazione del palco, non in posizione centrale rispetto al pubblico, a causa della conformazione del Parco Archeologico. “Il supporto tecnico di RCF in fase di progetto si è rivelato fondamentale” aggiunge il team di Provinciali srl. Il controllo dell’intero impianto è stato effettuato tramite il software RD Net, grazie a cui sono state gestite tutte le fasi di equalizzazione, allineamento di fase e gestione dei ritardi.
Sul palco si sono esibiti Subsonica, Marlene Kuntz, Caparezza, Bud Spencer Blues Explosion, Roy Paci Aretuska Allstars, Velvet, Francesco Baccini, Mama Marjas, Officina Zoè, Iosonouncane, Andrea Rivera, Ilaria Graziano & Francesco Forni, Brunori Sas, Diodato, LNRipley, Il Muro del Canto, Mannarino, Fido Guido, Bestierare. Un programma davvero ricco ed eterogeneo, che include svariati generi musicali, all’insegna di quella vivacità che caratterizza la scena musicale pugliese da alcuni anni a questa parte. Oltre ai grandi nomi si sono esibiti numerosi artisti emergenti da tutta Italia, scelti attraverso una serie di audizioni durante gli scorsi mesi, dando la possibilità anche a volti meno noti di suonare in un evento di grande portata.
We hope you had a great time, as we did.

Local authorities around the UK, faced with providing an ever increasing number of services from diminishing budgets, have been introduced to an elegant integrated ‘one button’ webcasting and audio/videoconference facility by Jon Hunnisett of technology specialists, Sound Advice PA Installation Ltd.
In designing a system that enables separate video and audio streams to be combined, councils can engage more with their constituents by allowing sessions to be web-streamed and viewed over the internet.
At the heart of his solution is RCF’s intuitive Forum 9000 digital conferencing and voting system, and Sound Advice has now built up a portfolio of 14 councils who have been eager to adopt this platform.
It was the versatility of the system that first caught the attention of Jeremy Luckett, Business Analyst at Wiltshire Council Unitary Authority, after five councils had been consolidated into three hub locations as part of the Council’s Transformation Programme Wiltshire.
This included a refurbished council chamber at County Hall, Trowbridge which contains 113 RCF microphone terminals for 98 members, plus support and smart cards embedded in each of the RCF mics (which allows the upload of data) along with two multi-function push-to-talk buttons. With the RCF camera facilitating automatic webcasting, this has opened up vast possibilities, which Wiltshire has wasted no time in exploiting.
At the client’s request, Sound Advice set up a Vaddio AV Bridge, with the ability to integrate audio and video equipment into a Microsoft Lync (Skype for Business) environment, thus enabling online meetings and general sharing capabilities. “The Council simply takes the video feed off the follow cameras and integrates it with the Lync video conferencing,” explains Hunnisett. “The RCF Forum channels audio and video in such a manner that bridges between a conference system and web casting — and the RCF system identifies who is speaking at any time via the smart card.”
At the same time the Lync video conferencing facility can also be used for other meetings and events hosted in the chamber (although not the formal council meetings).
Sound Advice had worked closely with Jeremy Luckett and Wiltshire Council’s ICT team, to create this single structured system, which can be shared by all public sector agencies, knowing that once set up the RCF Forum 9000 would run automatically.
“Jeremy had some innovative ideas,” acknowledged Hunnisett. “As for RCF, they have a proven track record of camera follow and webcasting, and we can pipe AV between the chamber and remote viewer bi-directionally over the internet. It’s highly cost-effective.”
Hunnisett describes the RCF software as the most intuitive and customisable on the market. “With councils unable to employ the personnel necessary to run camera follow, voting and agenda separately, the fact this can now be done with one easy-to-operate button on the Forum 9000, with a large amount of automation available behind it, is perfect — both from an operational and cost perspective.”
RCF’s flagship system controls four dome cameras — one fixed and three pan/tilt/zoom — in Trowbridge. Designed to meet the IEC 60914 standard, up to 240 FMS 9411-S consoles can be connected to the main FMU 9100 unit in this expandable system.
At the same time, Hunnisett observes that aside from the superior audio quality of the Forum 9000 “the electronic voting system in the chamber can cut meeting times down by at least half an hour when compared to the old manual hand count.”
Another feature is that the RCF system has also helped make the chamber paperless. Each station is designed so that the mic console is raised on a bracket and the councillors’ tablets can be neatly tucked under it. Running a Democratic Services System App on their iPads, agendas, minutes and reports can be automatically downloaded to an individual’s computer, and integrated with webcasting.
Summing up, Jeremy Luckett states, “We have succeeded in enabling this excellent system in an extremely cost-effective manner.The Forum 9000 provides far more than just a push and talk set-up, and we get a lot for our money. All the meeting facilities are now fully utilised and in addition to webcasting, it has helped us with staff training.”
The Chamber install forms part of a bigger package of innovative AV technology that Luckett has delivered for Wiltshire Council, covering meeting room booking, presentation equipment, digital signage and video conferencing.
As for the Forum 9000 this continues to help Sound Advice win a large percentage of tenders. “It hits the price point, is easy to operate straight out of the box, it’s flexible, cost effective and interacts with other systems … and all over a single CAT5 cable,” says Jon Hunnisett.
Finally, in addition to its local authority applications, the Forum 9000’s Simultaneous Interpretation features have also been used to good effect by Sound Advice at the University of Ireland School of Languages in Galway (among other establishments). In order to accommodate a course for Interpreters specializing in Gaelic, Sound Advice designed and installed the suite that provides 12 interpreters stations with 12 delegates units and a teacher’s master station, all digitally recorded.

When Konya was under consideration as one of the host cities for a future European Championships to be held in Turkey, construction of a brand new UEFA-compliant stadium was proposed.
While original plans set a capacity of around 33,000 seats, this was later upgraded to 42,276 seats — divided over two tiers, with an additional 50 VIP boxes — and the new facility, based in Selçuklu, will now provide the club Konyaspor KR with a state-of-the-art stadium for home matches.
Asimetrik, the Turkish-based distributors and AV system integrators, were awarded the contract to provide a network-based professional grandstand PA system, as well as broadcast infrastructure system, not only compatible with UEFA requirements (but also FIFA and IAFF). They also designed and supplied a PA/VA emergency evacuation system, C.I.S. infrastructure as well as full conference and visual presentation tools for conference, press and meeting rooms. All design, supply, installation and commissioning were undertaken by Asimetrik, who turned to RCF’s Acustica H Series as their primary sound source.
To ensure such seamless acoustic design and installation, Asimetrik worked alongside main contractor, Saridaglar Construction Company and engineers from the Konya Municipality from the very beginning to design a seamless acoustic environment. Led by their project manager, Burak Bayrak, they designed a number of unique solutions, using EASE Simulations to visualise the optimum distribution of sound to the seating areas, using the predictive software to set correct splay angles of the RCF loudspeakers and predict the performance with absolute precision.
Turker Baran, Asimetrik’s Acoustical Design Engineer, and Burak Bayrak knew that the RCF solution was a proven model, having been inspired by the installation at Juventus Stadium in Torino. “The H Series is also a perfect fit for this stadium — in terms of both power and dispersion,” says Mr. Bayrak. “RCF’s technical project team partnered us to design the system for Konya. RCF is a unique and well-established brand with a very strong history, and as a partner for 14 years we are delighted to be their distributor.”
RCF Acustica H1315 WP loudspeakers were used for the network-based professional grandstand address system. Asimetrik specified 96 pieces of RCF Acustica H1315 WP loudspeakers, a three-way full range loudspeaker that incorporates a 15in LF transducer, a 10in cone MF transducer and 1.4in exit titanium compression driver. These are mounted in double clusters across 48 rigging points, with a 12-metre distance between each cluster.
But installing the speakers on the catwalks had been something of a challenge. “We worked in coordination with the roof design officials to ensure safe installation and weight distribution, and we installed the clusters beneath the catwalk,” continues Mr. Bayrak.
The stadium exceeds the minimally required SPL set out by UEFA. Burak Bayrak stressed, “Our standard is based on the UEFA 2020 criteria for this stadium. Konya Torku Arena has an STI value of 0.8 — which is an excellent speech transmission index value.
After installation, NTI Audio XL2 Hand Analyzer (IEC 61672-1 Electroacoustics), NTI Audio Minirator MR-Pro Tone Generator, NTI Audio MA220 Type 1 Measurement Microphone and Norsonic type 1251 Sound Calibrator products were used for measurements and calibration.
The solution Asimetrik designed also included RCF loudspeakers for the main sound system, meeting rooms, and press room. Every audio product was carefully selected as being best fit for purpose, and for ease-of-use in multi-purpose situations.
Finally, to meet the UEFA specified media requirement, hybrid fibre cables, HD signal transmission cables, and digital audio cables were used along with an industry standard network audio infrastructure to control, process and distribute the sound. This also allowed Asimetrik to connect the main bowl system and PA/VA together, and have the stadium covered on a single site-wide network.
“Designing a system which is fully compliant with UEFA standards was very complex, but the RCF products were exactly what we needed to make it work,” concludes Mr. Bayrak. “The RCF H1315 sounds quality is superb and the system is extremely compact as well. A number of matches have already been played and we have had very positive feedback.”
“Uniting audiences with stimulating and high quality sound is a careful process especially at stadiums that are designed to be compliant with UEFA standards,” emphasises Gorkem Celikbilek, VP of Asimetrik. “The process incorporates a combination of experience and an obsessive attention to detail. We truly understand of the importance of sound quality. Our highly experienced team expertly analysed the properties of each space and we are extremely happy with the results.”
When Dave Ong set up Panache Audio Systems in Rochester, Kent, 17 years ago, RCF was one of the first brands he invested in.
He had run RCF rigs in his previous life as a DJ, and today — with his wide roster of production work complementing installation projects in the educational sector, he has recently invested again.
This time Panache has added eight elements of HDL10-A, the electronically processed, scaled down version of RCF’s groundbreaking HDL20-A active line array. And as an experienced sound engineer, he knew that by adding six of RCF’s SUB8004-AS (single 18in) enclosures he could create a cardioid broadside array to steer the low frequencies exactly where required in any situation.
Ong explains, “I had been looking for a mid-sized PA for sometime but there was just nothing suitable. The HDL20-A was a great box, but a bit too big for our purpose. But then the HDL10-A came out, which ticks all the boxes and fits into the price bracket.”
Housed in a stylish composite cabinet, this compact system is notable for its purpose designed transducers, 1400W peak power amplifier and DSP controlled input section (with selectable presets). “It’s a great system and I’m really enjoying using it,” states Dave Ong. “In fact it’s out on duty all the time".
“Because RCF make their own drivers the sound is incredibly hi-fi: people talk about the clean clinical top end is and how they can hear the separation and definition in the instruments.
“It’s also extremely powerful. In fact we’ve been using it in situations where we would previously have used our main large-scale PA system!”
Finally, he confirms, it’s an easy system to ground-stack or fly. “The way all the boxes link together with the built in bracketry is really straightforward and we can simply wheel in four cells at a time on the dollies, straight into position".
Dave Ong also gives himself even greater control by splitting the system, using a two-way analogue crossover to enable him to lift the bottom end via a separate aux in the mixing console. “That way, we get even more versatility,” he says.
And so the system joins a hire stock which also includes RCF’s big-selling ART series loudspeakers and P1108-T, weatherproof, wide dispersion and high quality 100V line system, popular at the annual ‘Winter Wonderland’ ice rinks.
Speaking of versatility, Panache Audio Systems also operate two outdoor mobile stage units, providing the client with a complete concert package, while Dave Ong also conducts regular workshops “to get kids interested in production at an early stage”.

The new Audi Arena Györ, described as “the newest and most modern hall in Hungary”, has been equipped with a major RCF system.
According to the Italian company’s Hungarian distributor, Chromasound Ltd, this 5,500 capacity multifunctional sports hall is without comparison when it comes to speech intelligibility — thanks largely to the work undertaken by their integration partner, G-Sound Ltd.
Jozsef Gricz was their system designer, working in cooperation with Laszlo Suto, and they specified 40 Acustica C5212-96 two way full range enclosures, with narrow 90° x 60° coverage pattern. These surround the sports field on all four sides in 20 clusters of two, hung from above. The speakers are faced on the upper (fixed) and lower (mobile) part of the audience area — with the underneath enclosures installed horizontally with rotated horns, on unique designed certified consoles.
Said G-Sound’s Jozsef Gricz “We’ve defined the distances from the seats and between the clusters, taking into account the horn opening angles, to ensure that this met our requirements.”
The 20 clusters are divided into eight zones, with the upper and lower speakers managed independently. The system is optimised via two dedicated RCF DX 4008 4-in/8-out digital loudspeaker management system, feeding 16 outputs. An amplification room is stationed in each of the four corners, with each position housing five IPS 3700 amps, RCF’s powerful 2-channel amplifier. The speakers are always driven from the closest amp rack to minimise cable losses (and compensate for other issues).
In addition to the installed and mobile PA for the arena, G-Sound Ltd also provided the entertainment system for the VIP areas and the multizone public address system.
Chromasound project manager Imre Makkay was supported by Andor Furjes (of aQrate Ltd), who masterminded the acoustic design of the Arena and assisted with control measurements. Explained the former, “The sound system was designed to deliver good tonality and goes sufficiently deep to fulfill the musical requirements on its own, or alternatively it can be matched with additional subwoofers, if extra low end is required.”
The Speech Transmission Index (STI) target was 0.5 with the arena full. At the first test, the Index’s average was measured as STIPA 0.51 in the worst conditions (all zones, but in an empty arena), and STIPA 0.68 with just one zone on (the arena still empty). “Of course, these values will improve when there is an audience,” notes Jozsef Gricz, “ and we are happy that we have met our target."
“The system can produce 98 dB LAeq and 113 dB LC peak levels at the listener positions, so it has enough headroom over the background noise."
“The overall frequency response is extremely flat (within ±3 dB from 50 Hz to 16 kHz), and the biggest difference is less than 12 dB on a specified frequency. So every spoken word and every sung note can reach its destination with complete clarity.”
He added, “Our main goal was to cover all seating with the same sound quality with the sound projected only where we want it to be. In real life the specifications have been verified, and the system delivers smooth transition between the different coverage areas.”
He added that different presets had been stored in the DSP, both with and without the use of the lower speaker, for when the mobile seats are not in use.
The public address system was also created from RCF loudspeakers and electronics ( ZM2100 system with UP series amplifiers, MQ80P, DP4, HD210T, PL60 speakers) with the public concourse and corridor areas, as well as changing rooms, divided for 10 zones. Its function is to broadcast the same music programme as in the Arena, and to make some calls for team players.
The Arena sound is also fed to the VIP area, where G-Sound Ltd has installed RCF Media Series with local sources (RCF MS1033), mixing (RCF L-Pad series) and amplification (RCF IPS 700 series).
Feeds to the system include announcers’ mics, interval music from playback devices and live music. There is a technical room where all the source selection, mixing (via Yamaha LS9-16) and routing take place. This can be fed by a mobile Dante stage box from several locations on the field and in the stands when a live
The new system made its debut in November at the Women’s EHF Handball Championships where Chromasound reports that everything worked perfectly.
The company has worked with RCF for the past four years. Summing up, Jozsef Gricz said, “It was a pleasure to work with Acustica series horns. In relation to the sound system there is no other comparable sports or multifunctional hall in Hungary that gives you the same audio experience from an installed sound system. Everybody wants to see and hear what has been achieved up in Györ".
