Installing The Epicenter (continued)
Adjusting ParaBASS® Controls
The bass response in a system is affected by four factors; (1) the
acoustics of the vehicle, (2) the location of the speakers, (3) the music
on the source unit, and (4) speakers and speaker enclosures.
Because of the variations in the recording process, we developed
The Epicenter to help restore any low frequencies lost during the
recording process, however, the acoustics of various environments
are different. With this in mind our coffee-laden engineers developed
the unique ParaBASS system.
The "Sweep" control allows you to select a center frequency (the
frequency most affected) between 27 and 63 Hz. The "Wide" control
then allows you to control the shape of the filter centered around the
"sweep" frequency.
Setting the Bass Output Control
The Epicenter is the most powerful bass component in the history of
autosound. Able to leap tall buildings with a single bound and all that
kind of stuff. With that in mind we have equipped The Epicenter with
several different Bass Output selections. If you should need to change
the settings, please use the chart below for guidance. A word of
advice: listen to the factory setting before changing your Bass Output
settings.

Oh my gosh!
PFM Subsonic Filter
Many car audio systems truly push the limits of their subwoofer...
without really knowing it. Tuned enclosures affect the roll-off of many
speakers, yet lots of source material forces the speakers to play lower
than expected. The net result is wasted amplifier power and damaged
speakers. The AudioControl PFM (Programmable Frequency Match
or Pure F#@&% Magic) filter is a programmable subsonic filter. It
allows you to only let the speaker play as low as it should be playing.
Because every system is different, we allow you to change the PFM
roll-off frequency to whatever you choose.
On most systems, the factory installed module (33 Hz) is fine. If
you know the tuning frequency of your speaker enclosure (porting
frequency or 3 dB down point), you might try setting your PFM
module to that frequency. If you want to protect your speaker system
even more, you might even try a higher frequency. Often a higher
frequency actually sounds louder and cleaner.
