5.2.5. Signal tuning
Due to their frequency dependant coupling, curved or
J-shaped line arrays require a set up related filter.
The reason for this can be explained by considering
the wavelength. Coherent coupling occurs when the
transmitted wavelength is larger than the radiating
source. It is easy to see that everywhere in the
audience area the entire array combines to provide
the lower frequencies, whilst at higher frequencies
only a single source provides energy at any point in
the listener area. The usual way to compensate for
this effect is by introducing a low shelf filter, where
the corner frequency and attenuation depend on the
size and the total vertical dispersion angle of the
array.
