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.

Memory Presets
There are four memory preset keys each with an
indicator above it in the ISIS VFD display. The indicator will
illuminate if that
memory preset is
currently in use.
Each preset stores
all the values for
each of the
following amplifier
controls:
*.)
GAIN
*.) EQ
*.) LO-PASS
*.) HI-PASS
*.) PHASE
*.) MUTE
*.) KOMPRESSOR
This gives you the
ability to dial in four
completely different amplifier settings and store them in pre-
sets for instant recall later.
It’s like a preset for your favorite radio stations...only better!
