Alongside the long-established Besiktas, Galatasaray and Fenerbahce, a fourth Istanbul club is making waves now on the Turkish soccer scene: Basaksehir, which was founded in 1990. The club’s new stadium seats 20,000 and satisfies the highest modern standards. An important role in this is played by the sound reinforcement system. The installation for this was entrusted to the Istanbul-based Electro-Voice distributor Atempo around Istanbul Regional Director Volkan Konuralp. The solution proposed by Atempo – a combined pro sound and evacuation system – beat out strong opposition to secure the commission.
During the planning phase, sophisticated simulation software was employed to discover the optimal sound reinforcement solution. This turned out to comprise 52 full-range enclosures from Electro-Voice’s EVH series to provide homogeneous coverage of the seating areas – the horns of half of these EVH-1152 cabinets have a 90° x 40°, and the rest a 90° x 60°, dispersion pattern; an N8000 digital matrix, which is responsible for the supervision and control of the installation; and 18 Electro-Voice CPS 4.10 power amplifiers equipped with RCM-810 remote control modules. These 4 x 1 000 Watts amplifiers employ a patented technology known as Variable Load Drive. This enables the power amplifier to always deliver full power at variable loads.
With this installation, Basaksehir Stadium becomes the latest in a long list of top international arenas now equipped with EVH enclosures from Electro-Voice’s EV Innovation series. “Basaksehir’s directors are extremely enthused by the performance of the system,” reports Konuralp: “announcements are clearly intelligible and the reproduction of recorded music is powerful with sound quality that is first class. For a Turkish stadium, this is something new.” Konuralp firmly expects the Basaksehir installation to become a reference in the region. The horn-loaded, weatherproof versions of these coaxial loudspeakers – fruits of the model diversity of the EV Innovation series – accord particularly well with the sound reinforcement needs of stadium planners.
The sound reinforcement design divides the Basaksehir Stadium into eight separate zones. All the power amplifier channels and loudspeakers are monitored and controlled by means of the graphic user interface provided by Iris-Net software running on a single PC. “This is convenient, quick and reliable,” points out Konuralp. “Furthermore, our customer is delighted with the sound performance, quality and wealth of options provided by the system.”
The offices, passages and turnstile areas in the Basaksehir Stadium are served by 80 EVID 6.2T loudspeakers, also from Electro-Voice.
Additionally, a Bosch Praesideo digital public address and emergency voice evacuation system connected to over 800 ceiling loudspeakers as well as a Bosch Plena Matrix digital sound system with 50 cabinet loudspeakers. Three Bosch fire alarm systems with nearly 950 smoke detectors and 160 fire remote indicators, CCTV with about 200 Bosch cameras as well as two Bosch access control systems round off the installation.
