PRESET PRESETS
Ok, we know that sounds like a certain pizza commercial,
but seriously the four memory presets come with settings
already in them.
You can use these as a starting point to do your own tweak-
ing or for quick push-a-button-and-be-done setup.
Any preset you store will replace the ones that come from
the factory. You can reset all four preset back to factory
defaults anytime simply by doing a reset in the RESET AMP
menu.
Here are the settings in each preset from the factory.

In more general terms, each preset offers you these
options.
Memory-1
sets the amplifier up with a 24 dB per octave
low-pass crossover at 80 Hz and an infrasonic filter (often
called subsonic filter) to protect the speakers from harmful
ultra-low frequencies.
Memory-2
sets the amplifier up with a 24 dB per octave
low-pass crossover at 80 Hz, an infrasonic filter (often called
subsonic filter) to protect the speakers from harmful ultra-low
frequencies and a 6 dB bass boost at 40 Hz.
Memory-3
sets the amplifier up with a 24 dB per octave
low-pass crossover at 80 Hz, an infrasonic filter (often called
subsonic filter) to protect the speakers from harmful ultra-low
frequencies, a 6 dB bass boost at 40 Hz and sets the
Kompressor into CONTOUR mode.
Memory-4
sets the amplifier up with a 24 dB per octave
low-pass crossover at 80 Hz, an infrasonic filter (often called
subsonic filter) to protect the speakers from harmful ultra-low
frequencies, a 6 dB bass boost at 40 Hz and sets the
Kompressor into RED-LINE mode.
As stated before you can always start with one of these
presets, tweak it to fit your installation and then save your
settings into a new preset.
