The opera house's main auditorium has seating on three levels - stalls and two main balconies, as well as eight side balconies. With the top tier 18m high and 40m from the stage, and other seating covered by the balconies, how to replace the existing system with a more effective solution posed a challenge for planners.
Focus Modular loudspeakers proved first choice for the main system due to their sound quality, precise coverage capabilities and unobtrusive appearance. A 7.48m column, comprising five loudspeaker modules, has been installed each side of the stage. Three wall-mounted, stacked FM-400 low-mid modules form the column's centre, with high frequency FM-110 modules added top and bottom. Each speaker's individually generated beams (one from the top FM-110, two each from the FM-400 modules and two from the lower FM-110) can effectively cover all seating areas without spoiling the audience view, or interfering with the architecture.
Fohhn Linea LX-150 and LX-100 passive line source speakers, driven by D-4.1200 DSP amplifiers, provide supplementary coverage for some of the side balconies. The aluminium housing of these slender systems has been colour-matched to the ventilation ducts on which they are mounted to blend with the interior.
For extended low frequency coverage, two of Fohhn's 21-inch PS-9 active subwoofers, clad and hidden from view at the side of the stage, provide precise and powerful reproduction in the 28 Hz - 110 Hz frequency range.
Coverage of the highest and lowest side balconies has been achieved using Fohhn's compact LX-10 ASX AIREA system loudspeakers, with an AIREA AM-20 Master module serving as the central digital interface for the speakers.
The entire sound system, including the Focus Modular loudspeakers, digital amplifiers and AIREA system components, has been incorporated into a Fohhn-Net network.
"We wanted to change our PA system, but it was important not to spoil the hall's beautiful architecture by having large stacks of loudspeakers everywhere", says Philippe Taberlet, technical director of the Opéra Bastille. "Then we discovered Fohhn. The Focus Modular systems have proved perfect for achieving high quality reproduction of music and voices, with their Beam Steering technology providing impressive, direct coverage possibilities. What's more, the speakers have integrated perfectly into the hall's interior, leaving its 'look' untouched. We're happy."
The Opéra Bastille installation was carried out by system integrator SILENCE! and Fohhn's French distributor Rock-Audio Distribution, in cooperation with Fohhn planning engineers.
