Speed skating world championships with Electro-Voice and DYNACORD

April 1st, 2011

-- In March 2011, the new Max Aicher Arena in Inzell opened in style with the speed skating Single Distances World Championships

-- The arena boasts a state-of-the-art sound reinforcement and evacuation system from Electro-Voice and DYNACORD-- The technical planning and installation of the sound system were performed by TRE Professionelle Audiotechnik of Parkstetten

-- Systems from Electro-Voice were also used in the venue’s Party Zone

The new Max Aicher Arena in the Bavarian resort of Inzell recently celebrated its grand opening with the Single Distances World Championships in speed skating, which ran from March 10-13, 2011. Work on the conversion of the old open-air stadium into the futuristic indoor arena that graces the site today began in September 2009 and cost 36 million Euros.

The Parkstetten-based firm of TRE Professionelle Audiotechnik was responsible for the installation of the sound reinforcement system in the thoroughly renovated stadium. A complex task, since in addition to the low ambient temperatures inside the new hall, the architecture of the building made the high level of intelligibility demanded by the client a tricky objective to attain. "The system we were asked to provide had to offer homogeneous and high-quality sound reinforcement as well as multiple input stations," explains TRE Managing Director, Robert Ernst. "Furthermore, the complex had to be subdivided into discrete sound reinforcement segments."

With the help of simulation software, TRE's planners were able to determine the ideal loudspeaker configuration for the arena: in other words, not only the optimal loudspeaker positions but also the models best adapted to occupy them. "It became clear that loudspeakers from DYNACORD and Electro-Voice were capable of outperforming their competitors by a wide margin, as well as offering far better value for money," reports Ernst. Many years of experience with DYNACORD and Electro-Voice in the field of stadium sound reinforcement, along with a long list of prestige related references worldwide, spoke eloquently in their favor.

To provide even coverage throughout the new complex, eighty-nine Electro-Voice Sx600 loudspeakers were installed. These were powered by twelve DYNACORD DSA amplifiers (8 x 500 W in each case). "The acoustic properties and weatherproof cabinets of the Sx600 loudspeakers have already vindicated their selection in numerous similar venues," explains Ernst. "But our personal favorites in this installation are the powerful DYNACORD amplifiers, which are remarkable for their compact format, low closed-circuit current and excellent audio characteristics."

The solution adopted in Inzell, as in many other modern sports stadiums and arenas worldwide, is a combined sound reinforcement (for musical material) and voice alarm system (for evacuation in case of emergency). In Robert Ernst's view, this is not only the “most appropriate solution these days”, but also one that is user-friendly and offers in this case – thanks to the quality and design of the components used – maximum security and reliability. "The supervision of the individual components afforded by this solution makes everyone's job a lot easier," Ernst explains. The centerpiece of the digital evacuation and voice alarm system, tried and tested in countless major installations worldwide, is the DYNACORD Promatrix 4000 – a failsafe solution that continues to function reliably even if the mains power fails. The control and supervision of the entire audio installation is performed by two DYNACORD P64-1500 audio system controllers.

Party Zone with MSE Tontechnik – and Electro-Voice

Whilst inside the arena over 6,000 fans were celebrating Jenny Wolf's victory for the fourth year running in the 500-meter sprint, thousands more were following the event on a giant screen in the Party Zone outside. The sound reinforcement here was the responsibility of the Stubenberg-based audio firm of MSE-Tontechnik. Some 20,000 sports fans visited the Party Zone at some stage in the course of the event, where an active three-way system had been installed, comprising Electro-Voice XLD281 line-array elements, flown Electro-Voice XS312 subwoofers and ground-stacked Electro-Voice Xsubs to reinforce the low frequencies. These were complemented by Xi1152A/64F loudspeakers for the near field. The entire installation was powered by Electro-Voice TG7 power amplifiers equipped with RCM26 modules, remote-supervised and controlled from the FOH position via IRIS-Net. "In spite of the cold," reports MSE Managing Director Johannes Schilling, "not a single component failed throughout the entire event. Everything worked perfectly. The new IRIS-Net V2.0 preset for the XLD loudspeakers proved particularly useful, convincing us right away."
