In the “CROSSOVER” menu, each short press on the MAIN CONTROL changes
the parameter being edited, between output, lter type, frequency and
aenuaon/topology. To select another output channel for eding, short press
the HOTKEY key on the corresponding output.

The adjustment can be carried out as
follows:
• Crossover
This funcon allows precision denion of the cuto frequencies for the high-
pass lter and the low-pass lter, as well as lter aenuaons and topology
individually by output. The available lters and aenuaons are:
• Balance / Delay
This funcon allows for the digital alignment of transducers (speakers) via the
me correcon performed by the DSP, and ensures that the sound from all
the speakers arrives at the listener with improved audio delity while avoiding

1. Idenfy the coil farthest from the
listener or the front panel of the box.
This coil will be used as a reference;
2. Measure the distance from the other coils to
the reference coil. These are the distances used in
conguring the delay of each output channel.
the “Encoder” dial changes the phase (0°

select another channel, quickly press the
corresponding HOTKEY shortcut.
• Phase
This funcon is used for resolving problems caused by canceling frequencies.
From this screen you can reverse the phase of all outputs individually. Turning
• Limiter
To protect your ampliers and speakers, the DSP 2.4X has a limiter with an integrated
“Dynamic Aack-Release” system for each of the 4 outputs. Use this funcon to
aenuate and prevent damage to the system caused by signal peaks.
The Threshold (-24 to 0dB) seng denes a threshold for the Limiter’s acvaon:
the Limiter kicks in when this threshold is exceeded.
The Aack parameter (0.1 to 100 ms) denes how fast the Limiter reacts / acts when
the signal exceeds the Threshold.
The Release parameter (1 to 1600 ms) controls the recovery me elapsed between
the me the signal falls below the Threshold and deacvaon of the Limiter.

• Gain
This menu allows you to adjust the gains of the
individual outputs within a range of -45 to +15 dB, as
well as to increase the master volume from 0 to 100%.
In addion to manual adjustments
of Aack and Release values, it
is possible to enable the “AUTO”
mode, where the Aack and
Release parameters are controlled
in real me by the “Dynamic Aack-
Release” system, providing ideal
condions for sound delity.
