Normal: leaves the phase unchanged

Reverse: shifts the phase through 180 , inverting it.

The effect of this control is summed with that of the parameter of the LPF filter (Xover - EDIT menu), which operates with 5 steps in a range of between 0 and 180.

In this way it's possible to set the phase of each individual output with 5 steps within a complete 360 revolution, a very useful function when assembling arrays of speaker enclosures, in the control of the interpolation between various enclosures or between sections of the same system.

5.3.7Output Limiter

a. Output level limiter

Allows to keep the signal of each individual output within a set level. Can be used effectively to protect the components of a sound system.

The following editable parameters are available:

b. Reaction times

Allows to choose between 3 types of Limiter reaction speed.

In fact, these are attack and release times that are optimised so that the Limiter reacts more or less rapidly when the signal exceeds or drops below the threshold:

Fast short times, suited to rapid Limiter operation. Normally more suited to outputs dedicated to high frequencies.

Normal intermediate times, suited to the majority of applications. Normally more suited to outputs dedicated to mid frequencies or full-range systems.

Slow long times, suited to avoiding rapid repeated level jumps (pump effect). Normally most suited to outputs dedicated to low frequencies.

c.Threshold

Allow to set the level above which the Limiter intervenes (limiting the signal) and below which it leaves the signal unchanged.

The editing values are within the following ranges:

+19.8dBu ~ -10dBu, with 0.2dBu steps 7.574V ~ 0.245V with variable steps

The measurement unit can be chosen with the Lim. Thresh. Unit function (UTILITY menu - Units submenu). The Off value disables the LIMITER, whereas any other value enables it.
