next component after The Epicenter Plus, such as a crossover, equalizer, or
amplifier.

5. Restoration Level Control/Source Selector: This knob allows you to in-
crease or decrease the bass restoration of The Epicenter Plus. Additionally, tap-
ping the knob will toggle between sources. You can mount the knob anywhere
you want, although somewhere in the front of the vehicle is preferable.

6. Remote Out: Outputs 12 volts when the The Epicenter Plus is powered up
so you can turn on external devices like signal processors and external amplifiers
or relays if necessary. Do not use for system power!!

The Inside
RCA Input Grounding: Depending upon the wiring topology of your audio
system, some components may look for an “audio” ground through the RCA
connectors or speaker wires. In this case your system may encounter engine
noise whine. For most systems you can leave this jumper set in the UNBAL-
ANCED position. In the event you need additional noise rejection you can
change the jumpers to the BALANCED position.

ANCED position. In the event you need additional noise rejection you can
change the jumpers to the BALANCED position.
Ground Isolation Jumpers: Occasionally alternator whine may appear in a
system because the source unit and amplifier use different grounding. To help in
this situation, we have provided alternative grounding connections. Make sure
your system is turned OFF before you move these jumpers.

Bass Maximization Circuit: Not all systems are designed the same. Some
systems are designed strictly for SPL (sound pressure level) while others are
a little more passive. The Bass Maximization circuit can either increase or
decrease the mix signal voltage of the bass restoration circuit. Depending upon
your system, you may opt to change these jumpers to a higher or lower setting to
maximize your bass output and protect your speakers. In most systems the fac-
tory setting will suit you fine. We recommend you try the factory setting first.

PFM Subsonic Filter: The Epicenter Plus utilizes a PFM (Programmable
Frequency Match) filter which will help with speaker control and amplifier
power management. To change the PFM frequency, you need to remove the top
of the chassis and change the modules. Your local AudioControl dealer gener-
ally carries an assortment of these replacement modules. This is discussed in
detail on page 10. Once again, we recommend you try the factory setting first.
