Avi-Sys selected QSC's highly-regarded CX Series amplifiers for their reliability and sonic output quality, along with the company's CM16a amplifier network monitors and QSControl, QSC's Ethernet-based network audio system - to power and control the Kling & Freitag loudspeakers in the three event centres within the building.
According to Avi-Sys' Dieter Loeffler, the big acoustic challenge was to achieve good sonic results - despite the presence of highly reflective glass walls. The various rooms seat 100, 300 and 500 people respectively, and since they are mainly used for meetings, conferences and lectures, speech intelligibility was the principal consideration.
Avi-Sys selected a combination of Soundcraft Series 4 mixing consoles and a BSS Soundweb digital networking to service the three Event Centres in the 48-storey skyscraper. These Event Centres - seating 100, 300 and 500 people respectively - are mainly used for meetings, conferences and lectures, placing a high emphasis on speech intelligibility.
Six BSS 9088ii line-configured Soundwebs and a 9000ii hub are used to network the Event Centres and process the signals mixed from a pair of Soundcraft 32+4 Series 4 consoles - preferred by the complex's technicians, who were familiar with both the desk and the Soundcraft pedigree. According to Loeffler, the big acoustic challenge was to achieve good sonic results - despite the presence of highly-reflective glass walls - and the gain settings stored in Soundweb were paramount to achieving this. "There was another reason for choosing Soundweb," he explained. "The system operates in two distinct states - manual and fully automatic mode.
Collaborating with Murphy/Jahn was the German architectural firm of Neinle, Wischer und Partner, while structural engineering was performed by Werner Sobek Ingenieure GmbH, with mechanical engineering by Brandi Consult GmbH.
"The whole system is under Crestron control, and in automatic mode Soundweb not only offers us control flexibility but all the software to make it function easily with Crestron. For this type of installation it is perfect."
