Owners Enjoyment Manual

ongratulations on your acquisition of the finest bass restoration processor
known to the autosound world. Whether this is your first AudioControl

C

product, or you are already a firm believer, you will definitely enjoy The

Epicenter Concert Series.

Now before we get too far along here, we need to give you a simplistic
explanation of bass and its multitude of applications. Regardless of your age
or musical preference, the addition of low frequency bass to your autosound
system is truly an enjoyable experience. Whether you listen to the kettle drums
of Beethoven’s fifth symphony or you prefer the tones of rap music, bass will
truly enhance the performance of your system. Of course, some people enjoy
more bass than others, and for that reason The Epicenter comes with a dash
mountable control knob which allows you to increase or decrease the level of
the bass restoration effect. No matter what your choice of music, you will
absolutely love The Epicenter.

Now before you start salivating too much just thinking about what The
Epicenter can add to your system, take a few minutes to sit back, have a latté,
decaffeinated if necessary, and read through this manual. It contains lots of
useful facts and information (and besides, we spent a lot of time writing it)!!

FEATURES

Patented Bass Maximizer

The Epicenter contains a bass maximization circuit that accurately
recreates and injects low frequency information back into the signal path.
What that means in everyday terms is that The Epicenter will give more bass
impact to your best compact discs or even your old tapes. US Patent
#4,698,842

Para-Bass

What’s the use of having good bass if you can’t control it? The Epicenter
has a unique equalization circuit that contours the restored bass to your speaker
system.

Dash Mount Control

The Epicenter is designed to be mounted anywhere in the vehicle, with the
exception of the front bumper or radiator. It comes with a dash mountable
control that allows you to enjoy the effects of The Epicenter without having to
leave the drivers seat. The dash mount control also has a dual color LED
indicator that can be rainforest green or sunshine amber. This LED will grow
brighter as you add more bass or dimmer when you decrease it.

Bass Maximizer Indicator

Not only does The Epicenter Concert Series provide magic to your ears, but
it also gives you some visual enjoyment as well. On the chassis of The Epicen­ter is a backlighted logo that flashes when the bass maximization circuit is
activated. Special effects in your trunk!

PFM Subsonic Filter

This unique feature is legendary with many AudioControl fanatics for its
ability to fine tune the bass response of any system. Why waste power on nasty
subsonic information when your Programmable Frequency Match (PFM) filter
can help you clean things up?

Bass Output Control

The Epicenter circuitry has the ability to produce large amounts of deep,
mind shattering bass without damaging your speakers. The Bass Output
Control circuit allows The Epicenter to maximize the bass output of any
autosound audio system while restraining destructive bursts. Yeh!!

The most important feature of all. Every
AudioControl product is selflessly designed and
manufactured by the occupants of our
rainforest factory. We take every effort to
ensure that you will have many years of enjoyment out
of The Epicenter. To further ensure the performance of your new
toy, we highly recommend that you allow your authorized AudioControl
dealer to perform the installation. Not only do they have all the right knowl­edge and tools, but in the unlikely chance The Epicenter should fail, we will
back it with a limited five year parts and labor warranty. Should you choose to
install it yourself, we will still give you a one year parts and labor warranty. To
activate your warranty, you need to FILL OUT AND SEND IN YOUR WAR­RANTY CARD!

We also recommend that you save your invoice or sales slip as proof of
installation and ownership. Not only is it necessary for warranty purposes, but
should your Epicenter turn up missing some day while you are out watching the
submarine races, you will find insurance companies very unforgiving.

We interrupt your reading of this manual to provide the

impatient people with “Quick Install” information and guidelines:

The AudioControl Epicenter was designed to produce bass

like you have never heard before. With that said it is important

to take the following precautions during its use.

1. If you have an equalizer in your system, turn down

the bass frequencies and use The Epicenter. The results

could be, shall we say. . . interesting.

2. You will want to reduce any bass tone control,

loudness control, or other secondary bass controls prior to
turning on The Epicenter. Once your system is up and running, you may then
opt to use them again, although we doubt it!

3. Good bass response requires an appropriate choice of speakers and
amplification. Since the bass frequencies always require more power and cone
area than higher frequencies...BE PREPARED. Small speakers and lack of
power will be detrimental to your system.

Quick Install Information

The Epicenter Concert Series needs to be installed in the signal path
between a source and an external amplifier(s). Although it can be installed
after an equalizer, it must be installed BEFORE A CROSSOVER.

Once this is done, you just need to hook up power, ground, trigger, run the
wire to the dash remote and tada!!! Instant bass. If you need to know more,
then read on. Heck if you don’t think you need to know more, you should still
read on, because you can never know too much.

A GUIDED TOUR OF THE EPICENTER CONCERT SERIES

The Outside

Ê Inputs: The inputs of The Epicenter use a balanced input circuit to
help minimize induced noise. They are also designed to handle very high
signal voltages up to 15 volts!!

Ë Outputs: These RCA connectors should be connected to the next
component after The Epicenter, such as a crossover, equalizer, or amplifier.
Just remember, The Epicenter should go inline before a crossover!!

Ì Dash Control Input: This allows you to connect The Epicenter to the
remote “Dash Control” knob. You can mount the knob anywhere you want,
although somewhere in the front of the vehicle is preferable.

Í Power Connector: This nifty little connector allows you to connect the
Power, Ground, and Remote Turn-On signals to The Epicenter. Just connect
all the wires to their appropriate locations in the bright sunlight and then plug
it into The Epicenter mounted in the dark cavern of your trunk.

Î Para-Bass Controls: These 2 knobs control the Para-Bass functions of
The Epicenter. The “Sweep” knob allows you to pick the center frequency that
you want The Epicenter bass restoration circuit to maximize. The “Wide” knob
adjusts how wide of a frequency range The Epicenter will effect. Very cool!!

Ï Power: When you have connected all of your wires correctly you should
congratulate yourself when this light comes on. No light??? Check your wires.

Ð Display: Lights on. Lights off. That’s what happens to this display
when The Epicenter circuit is activated. Even if bass has numbed your ears,
you can still enjoy The Epicenter.
