Auditoriums

Designed by Valencia-born architect Santiago Calatrava, this visually stunning exhibition and convention centre has left its own indelible footprint on the local landscape. The main auditorium is an unusually shaped 2500m2 hall with a seating capacity of 2,144 seats, with a height of 45.16m up to the dome.

With the complex geometry (and high reverberation time) of the room, the choice of sound system was critical and in order to achieve optimum intelligibility given these challenging conditions, it was logical to propose a system with a large coverage control pattern, especially in the vertical plane.

Two hangs of 24 O-Line elements, with a 2.82m drop were flown on either side of the stage.

Installers MEDIACOM 95 and GMI, preferred to divide each column of the array into three zones or channels of amplification to produce a higher level control in the audience. Processing was carried out in a Martin Audio DX2 4in/8out DSP environment, which manages the different levels and equalization of each column.

Initially presenting a 2D model using O-Line's own software, before constructing, a 3D visualization using EASE software was created, in order to study the coverage throughout the room and the predicted levels of intelligibility.
