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 into full-range mode with a
infrasonic filter (often called subsonic filter) to protect the
speakers from harmful ultra-low frequencies.
Memory-2 sets the amplifier into low-pass operation with a
infrasonic filter. For use when the amplifier is driving a sub-
woofer.
Memory-3 sets the amplifier into high-pass operation. Used
for powering up a set of coaxial or component speakers when
another amp is driving a subwoofer.
Memory-4 sets the amplifier up for mid-bass duty. Perfect
for a set of KICKER mid-bass drivers.
As stated before you can always start with one of these pre-
set, 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 presets for instant recall
later.
It’s like a preset for your favorite radio stations...only better!
