FBT's digital sound technology improves word intelligibility in places of worship

The parish of Saints Justa and Rufina of Seville now has a sound system based on the digital columns of this manufacturer, according to the installation project carried out by the specialist Daniel Sonido, official Magnetron distributor for professional audio products.

With a main nave of 20 meters wide and equally deep and 7 high, approximately, and a roof formed by two flat gabled panels, the Sevillian parish of Santas Justa and Rufina does not offer the best environment for sound coverage during acts of worship to be good due to the dimensions and structure of the temple, with a reverberation time of more than four seconds.

This complicated situation causes the intelligibility of the word to be practically nil, with the detriment to the faithful, which has motivated the search for an audio system capable of controlling radiation lobes, both in vertical opening and in angulation, in addition to the sound pressure offered by each of the speakers that make up the column, so that this sound pressure throughout the ship is constant.

The audio project made by Daniel Sound, official distributor of Magnetron, is based on the sound technology of the Italian manufacturer FBT, whose systems this wholesaler sells in the Iberian market, as well as in the DLA range of digital speakers of this company, able to solve the acoustic problems that were presented in this installation.

The solution consists of two boxes with self-powered digital processing DLA 804A, and two small Project passive boxes 320, as reinforcement for the rear.

The choir area and the entrance hall of this parish has been equipped with passive boxes and ceiling speakers of the CSL series, attacked by an MXA amplifier 1120.

In the area of the presbytery of the temple two Project boxes have been installed 540 from this manufacturer, along with an MXA amplifier 1060 to monitor the priest.

As far as the microphone is concerned,, meG14-40 models have been chosen Sennheiser (brand that also sells Magnetrón in Spain) with AC ST bases 550 of FBT, given its value for money.

Automatic mixing of all sound signals is done by a digital DMM processor 8008 of FBT, that allows an antifeedback control for each of the microphones installed independently, as well as the control of the noise doors associated with these devices.

Thanks to the eight outputs of this processor, you can also independently control the audio and equalization levels of each of the areas to be sounded in this worship space.
