JBL technology solves acoustic problems in sports halls

The Colegio Maristas Santa María de Orense has reversed the poor coverage of its sports space by a quality sound, according to the project carried out by Selas Systems.

The technology services company Selas System, Specialized in image and sound solutions, has been in charge of the sound project of the sports pavilion of the Marist School Santa María de Orense (Colexio Maristas Santa Maria).

The poor acoustics of this Galician sports venue made it necessary to install a new sound system with controlled coverage, that has been achieved with Constant Beamwidth technology, patented by the manufacturer JBL Professional, brand of Harman that sells in the Spanish market Earpro.

In addition, these systems incorporate Constant Beamwidth technology, patented by JBL Professional, which represents a significant advance in the consistency of pattern control, achieving superior and uniform vertical coverage, while reducing the narrow vertical beam and out-of-coverage lobes typical of passive column speakers.

Thanks to its frequency and power response, These teams provide great performance, especially in environments with poor acoustics and reverberation, As often happens in sports halls as in this case.

A power stage has also been installed for the project XTI2002 Crown, controlled by DSP, as well as a signal processor for installations of the ZonePro 641M model, with six entries, four micro lines with Phantom and two line, together with ZC1 programmable volume control, All of the brand DBX, also by Harman.

For acoustic warnings in the enclosure the option has been a combination with dual wireless transmission, which consists of the SM58 handheld microphone and the SM35 headband microphone, both of Shure.
