Directional coverage
Thanks to the vertical beam control, UDA 16 concentrates power on the area that has to be covered, minimizing
the secondary lobes effect.
Sound pressure levels
Thanks to the cylindrical dispersion (waveform), sound pressure level only decreases around 3 dB (instead of 6
dB) erach time the distance doubles.
Uniform dispersion Array
The main advantage of a controlled beam (Uniform dispersion) line array systems is that the audio spectrum
that wants to be reproduced has the same dispersion in all the band giving a CONSTANT directitvity index (see
figure), against the conventional array systems which directivity depends on the frequency, which means different
frequency remains in different dispersion so the energy audio levels received by the audience varies in frequency
hearing consequently a different sound that the one reproduced by the system.
Resuming, a Uniform Dispersion Array like UDA 16 ensures that the sound pressure received by the audience is
the same in all the band that needs to be reproduced meanwhile with conventional array systems the sound level
varies having more pressure in high frequencies and lower in low frequencies (because the low ones are less
directive).
In conventional array systems, because of the directivity varies on frequency also the distance to be covered is
different, where audience located long distance from the column receives only high frequencies.
This problem is solved by Uniform Dispersion Arrays where all band to be reproduced has the same dispersion
so the audience located long distance receives the same proportional levels that the audience located nearer so
no matter how near or far audience is from the source, they will receive an uniform audio level.
