practical problems of space. Practical experience has taught us that the subdivision of all subwoofers in
different groups in front of the stage provides a better distribution and reduces phenomena of interfer-
ence, without having to insert separate processing and without placement constraints.
The use of suspended subs, as in the case of satellites, allows a better distribution of the sound
pressure level on the whole audience area. The subs can be placed on a separate array or combined
with the satellites in a single array. When the subs are flown in a separate array they should be placed
behind the satellite array, whenever possible, so to take advantage of the directivity control that this
arrangement creates. Instead, when you have arrays of satellites and subs, you should mount the subs
in the upper part of the array, or in symmetrical order in the upper and in the lower part of the array,
which will once again create a certain directivity diagram due to the distance between the sub sources,
with all of the advantages and disadvantages of this phenomenon.

4.6.2 Temporal Alignment

Every time you mount the equipment, you need to verify the processor setting of the delay time. Presets
are provided with mechanic alignment, that is aligned to suit the situation in which a satellite is placed
directly on top of a sub. The detailed description of the alignment operation is in chapter 6.
