Electro-Voice helps audio quality to soar in Middle East Airlines Training and Conference Centre
Lebanon – For Lebanese systems integrator AMAC Company, overcoming the acoustic challenges that were inherent to The Dome, part of Middle East Airlines’ Beirut-based Training and Conference Centre, was the kind of challenge that could only be overcome with experience and superior technology.
The Dome is well named; a large multi-purpose space, it extends over an area of 475 square metres, and its roof peaks at a maximum height of 19 metres. The building’s shape, explains AMAC company technical manager Georges Tabet, meant that: “Acoustically it was a real challenge. The average reverberation time was between 25 and 30 seconds, and we needed a solution that could deliver audio equally all through the space. A local point-source design was an option, and through EASE modelling it became apparent that two arrays, flown from the ceiling, provided the best method of coping with the spherical architecture.”
Having used Electro-Voice loudspeakers for a number of previous conference centre projects, Tabet knew that he could rely upon on the EVA (Expandable Vertical Array) series, part of the EV-Innovation family for fixed installation. In addition to the advanced Hydra plane wave generators and constant directivity waveguides inside the boxes, the EVA enclosures offer integrated rigging hardware and a choice of finish options to ensure they blend into the background for a clean installation.
Each array comprises four EVA-2082S modules and six EVA-2082S modules. They are augmented in the low end by two matching EVA-1151D 15” subwoofers, while two Electro-Voice Xw12A 12” floor monitors provide foldback for presenters and performers. The entire system is powered by eight Electro-Voice Q1212 amplifiers.
“Everyone is delighted with the new system,” says Tabet. “We were asked to deliver good intelligibility to the entire audience, which can be as many as 400 people seated or 500 standing. From training pilots to performances by solo musicians and small bands, the EV system has delivered on every expectation.”
