RCF will be displaying their worldwide success of stadium installations in the Stadia Corner of their Infocomm 2015 booth # 1167 in Orlando, Florida June 17-19.
More details from RCF USA (www.rcf-usa.com):
The 68,000-capacity Baku National Stadium is a new retractable roof stadium that opened in March in the Azerbaijan capital of Baku, built to Olympic standards for use for soccer and other athletic events, as well as the 2015 European games.
RCF’s Engineering Support Group worked together with Gorkem Celikbilek of Asimetrik, who designed a system around RCF custom TTL55-A line array modules. The modules were chosen because of their vocal clarity and high SPL of more than 120 dB. 270 TTL55-A modules with customized for the project. Custom frames were constructed to mount clusters of 17 TTL55-A and 10 TTL55-A to cover the wide angle of the tribunes. Additional AYRA 6 monitor speakers, Acustica C3110, H1315 and S4012, along with P2110-T weatherproof speakers were also deployed throughout.
In Germany, the 80,000-capacity Dortmund Stadium recently employed a radical upgrade to its public address system. The goal was to achieve higher intelligibility, even pattern control with extended low frequency, and unobstructed sightlines.
Working with German Fulfil Engineering GmbH, the RCF Italy Engineering Support Group design a system comprising 14 clusters of 14 TTL33-A three-way line array elements along with a single TTS26-A dual 15” subwoofer at the base of each. The unusual design of the clusters created a vertical angle of approximately 140-degrees, firing into the back of the upper and lower tribunes and outwards to the edge of the pitch. All clusters were wrapped around the beams of the facilities to keep sightlines intact. All 196 active line array elements were weatherized.
Aside from the benefits in cost savings of utilizing active loudspeakers versus more traditional passive solutions, the RCF Engineering Support Group also promoted the advantages of a single active line array source over individual speaker distribution, arguing that this would deliver coverage consistency and eliminate phase cancellation caused by the sound arriving in different zones at different times.
RCF continues to be a leader in facility designs with other recent installations at the 33,000 seat Torku Arena in Korea; 5,500-capacity Audi Arena Gyor; and the 1,500 seat Mercyhurst Ice Arena in Erie, Pennsylvania.
RCF has also recently introduced the new line of HL Series horn-loaded, long-throw cabinets for stadium needs. The dual 12” two-way, 1500-watt biamp passive weatherproof cabinets feature a narrow pointsource 22.5-degree vertical coverage with options of 40, 60 or 90-degree horizontal. A matching 900-watt subwoofer is also part of the series for true line array distribution of sound.
All these products will be on display in the Stadia Corner of the RCF USA booth # 1167 at Infocomm, with members of the RCF Italy Engineering Support Group on hand.
