ROTTERDAM, Netherlands — The Luxor Theatre, used for musicals, variety shows, stage plays, rock concerts and other events, has been equipped an Alcons loudspeaker system, which beat out two other competing systems in a staged demo event.
For the demo, in-house Luxor technicians and other sound designers and engineers were invited to give their opinion. The Luxor Theatre eventually selected a main audio system by Alcons using three (LCR) clusters comprising 12 line-array units each.
The hall of Luxor is high and features two balconies. Imaging-wise, addressing the complete hall using these three clusters is not a good option. The first rows until the cross path in the middle of the ground floor are therefore addressed by two small clusters of four LR16 line-array cabinets each. The takeover area between these small clusters and the main clusters is just in the middle of this centre path and therefore offers no problems.
The complete five-cluster system includes 32 LR16 and 12 LR14 line-array cabinets. Two additional VR12 loudspeakers address the front rows, just in front of the main stage. There are also four small SR9 infill speakers for two problem areas underneath the balconies on the left and right hand side. Four BF362i subwoofer cabinets supply the low frequencies.
Peter Kaandorp of Dutch installer Sinus Pro BV from Hoofddorp carried out the project. The amplifier racks are located on the left and right hand side of the stage and were constructed by ISO-Audio from Amsterdam.
The Alcons ALC-amplifiers (a total of 19 units) are driven by two Dolby Lake processors, where all data port outputs of the amplifiers are integrated within a network using QSControl Amplifier Network Monitor. All amplifiers can be monitored from one computer using this system, so cable or loudspeaker defects can be detected instantaneously.
Management at the Luxor Theatre is said to be very satisfied with their new system.
