IPIC Arena gets Harman solution
UAE: GSL Professional has designed and supplied Abu Dhabi’s IPIC Arena with a new sound system. The solution calls on a variety of Harman products.
In its quest to maximise bookings from sporting, entertainment and corporate event promoters, the IPIC Arena is multi-functional in its design. Located in Abu Dhabi’s Zayed Sports City and operated by International Vision Investment LLC, the 6,000 capacity indoor flexible space attracts school classes, symphony orchestras, conferences and concerts, although it has quickly established itself as the venue for jiu jitsu and kick boxing tournaments.
Varying in size from 1,200 to 2,500 sq-m, the main arena floor integrates flexible, retractable seating for 3,400-6,000 spectators, although a permanent sports floor is in place year round for concerts, performances and exhibitions. In addition there are also eight VIP sky boxes, a Business Club and three conference rooms.
Programme and events manager Frank Matheisl called upon Dubai-based GSL Professional to design the sound reinforcement system inside the main 60m x 40m arena for commentaries and announcements. Trinity was appointed as the systems integrator for the resultant works.
‘The reverberation time was poor as a result of the 12m ceiling and concrete walls,’ revealed GSL Professional technical manager Georgi Hristov. ‘To ensure intelligibility and an even dispersion of 106dB SPL throughout the seated areas, I promoted a distributed audio system to be permanently integrated into the main arena.’
Having created simulations using EASE prediction software, Mr Hristov’s passive design was approved. As such, the four terraces of audience seating are served by eight ceiling suspended clusters each consisting of three JBL VRX932LA cabinets on a VRX-AF array frame. Weighing 21kg, each 800W two-way model combines a 12-inch woofer with three 2408J annular ring diaphragm HF drivers attached to a constant curvature waveguide. Whilst four separately suspended VRX918S subwoofers enhance the lower frequencies down to 34Hz, the players and contestants are catered for by an additional central cluster boasting four AE5125 speakers.
Six DCi 4|1250 multichannel amplifiers from Crown’s DriveCore Install series supply the power to all the loudspeakers within 100m from a rack in the control room. ‘The DCi Series are very green on account of their remote on-off interface, power factor correction and an efficient cooling design, so this saves the venue money over a period of time,’ furthered Mr Hristov. ‘In addition, the channels are bridgeable.’
Loudspeaker management is the domain of BSS Blu processing, which can be controlled remotely via an iPad using Soundweb or manually by a Blu-8v2 wall mounted zone controller. Presets have been programmed for ease of use, dedicated to coverage on the pitch, the seated areas and the entire venue.
‘As the previous system could only produce a maximum SPL of 85dB, we have provided the IPIC Arena with a much more powerful solution on a restrictive budget. Whilst being easy to use, the audio is evenly distributed thus enhancing its multi-purpose credentials,’ concluded Mr Hristov.
