parameters
In these pages, the number of the parameters and how they are presented varies according
to the configuration of the PRESET and according to Ganging and Units settings (UTILITY menu). In fact, these pages
only show the parameters that can actually be used, in the most suitable form of editing.
The practical differences between Delay Input and Delay Output
A Delay is only a processor by means of which a signal is deliberately delayed by a programmable length
of time. From a technical point of view, the Delays applied to the inputs and outputs are equivalent.
Nevertheless, their application is different:

Input Delay delays the signal of an input (or the sum of the inputs) before sending it to the routing system. In this
way, all the outputs which depend on that input are delayed by the same length of time.
Also called Master Delay, input Delay is mainly used to compensate for the effects dues to the distance
between the various speaker enclosures or between various blocks of a complex sound system (for
example in large concert halls, stadiums, etc.), thus achieving virtual alignment.
+
Output Delay only delays the signal of a specific output.
Also called Channel Delay, output delay is mainly used to compensate for the distance between different
blocks of the same sound system (for example clusters) or to correct internal alignment of a speaker
enclosure’s components.
