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 tweaking
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 Amp 1 and Amp 2 into full-range mode with a
infrasonic filter (often called subsonic filter) to protect the
speakers from harmful ultra-low frequencies.
Memory-2 sets Amp 1 and Amp 2 into high-pass operation. Used
for powering up a set of coaxial or component speakers when
another amp is driving a subwoofer.
Memory-3 sets Amp 1 and Amp 2 into low-pass operation with a
infrasonic filter. For use when the amplifier is driving a
subwoofer.
Memory-4 sets the amplifier up for Bi-Amp duty. Amp 1 is setup
for use with coaxial or component speakers. Amp 2 is setup for
subwoofer duty with an infrasonic filter.
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.
