If you like the LC2i, you’ll love the
EQX Equalizer/Crossover

Now that you have a great sounding preamp
signal, and you have restored the bass from the
factory roll-off, the next step toward sonic
perfection is to match the entire system to
your car. The EQX equalizer/crossover has 13
bands of equalization and a 24-dB Linkwitz­riley crossover to fine tune your system for
that true sonic nirvana.

GTO™ Great Turn On: No need to look

for a trigger wire.

The LC2i turns on all by itself. Just
hook up the speaker level inputs
and as soon as you turn on the
factory audio system the LC2i
will power up as well. After
the LC2i turns itself on, it
provides a 12 volt trigger
output to turn on your
amplifier.
A Jumper
which you
can reach from the end panel allows you to set this
feature on/off for specialized installations. The factory
default setting for the GTO™ circuit is always ON.

Setting the AccuBASS™ Bass Compensation:
Factory speaker systems have trouble reproducing loud
clean bass. Some companies systems limit the
bass at higher volumes so as not to damage
speakers. The AccuBASS™ circuit puts that
bass back.

Here’s how you set it up. After the
LC2i /Amps/ and speakers are in­stalled and ready go:

Turn the system on and play

1.

some music with a good bass
track.

Turn the volume up while

2.

listening for the bass.

AccuBASS™ Threshold control

GTO™ Selector

AccuBASS™ Level control

®

If you hear a spot where the bass just drops right out…

3.
stop. Leave the volume there and go to your LC2i.

Set the AccuBASS™ Level control on the top of

4.
LC2i to the center detent.

Now, use a small screwdriver to turn the Threshold

5.
control clockwise slowly until you hear the bass pop
back in.

Re- adjust the AccuBASS™ Level control on the top of

6.
the unit to get the proper amount of bass compensa­tion, and you’re ready for some ground pounding bass.
OK, what if your bass doesn’t roll off, but you still want
more?

No problem! Turn the AccuBASS™ Level control fully
down, rotate the threshold control fully clockwise to
lock in the bass equalization. Now you can turn up the
AccuBASS™ Level control for the amount of bass you
want.

Conditional Warranty

People are scared of warranties. Lots of fine print, lots of
noncooperation, months of waiting around. Well, don’t be
scared of this warranty. It’s designed to make you rave about us
to your friends. It’s a warranty that looks out for you and helps
you resist the temptation to have your friend “who’s good with
electronics” try to repair your AudioControl LC2i. So go ahead
and read this warranty, then enjoy your new component for a
few days before sending in the warranty card and comments.

“Conditional” doesn’t mean anything ominous. The Federal
Trade Commission tells all manufacturers to use the term to
indicate that certain conditions have to be met before they’ll
honor the warranty. If you honor these conditions, we will
warrant all materials and workmanship on your LC2i for five
years from the date you bought it, if installed by an authorized
AudioControl dealer, and will fix or replace it, at our option,
during that time.

Here are the conditions that make this warranty condi­tional:

1. We need to know that you bought your product from an
authorized AudioControl dealer. So go to
www.audiocontrol.com or audiocontrolregistration.com right
away, and register your LC2i.

2. You must keep your sales receipt for proof of purchase,
showing when and from whom the unit was bought. We’re not
the only ones who require this, so it’s a good habit to get into
with any major purchase.

3. Your LC2i must have originally been purchased from an
authorized AudioControl dealer. You do not have to be the
original owner, but you do need a copy of the original sales slip.

4. You cannot let anybody who isn’t (A) the AudioControl
factory; (B) somebody authorized in writing by AudioControl
to service your LC2i

If anyone other than (A) or (B) messes with your LC2i , that

voids your warranty.

5. The warranty is also void if the serial number is altered or
removed, or if the LC2i has been used improperly. Now these
sound like big loopholes, but here is all we mean by it.

Unwarranted abuse is (A) physical damage (don’t use the LC2i
for a jack stand); (B) improper connections (120 volts into the
power jack can fry the poor thing); (C) sadistic things. This is the
best mobile product we know how to build, but if you mount it
to the front bumper of your car, something will go wrong.

6. If an authorized United States AudioControl dealer installs
your LC2i, the warranty is five years, otherwise the warranty is
one year.

Assuming you conform to 1 through 6, and it really isn’t all
that hard to do, we get the option of fixing your old unit or
replacing it with a new one.

Validate your warranty: Visit audiocontrolregistration.com to
register your LC2i.

Legalese Section

This is the only warranty given by AudioControl. This
warranty gives you specific legal rights, which vary from state
to state.

Promises of how well your LC2i will work are not implied by
this warranty. Other than what we’ve covered in this warranty,
we have no obligation, express or implied. Also, we will not be
obligated for direct or indirect consequential damage to your
system caused by hooking up the AudioControl LC2i.

Failure to send in a properly completed warranty card, ne­gates any service claims.

Most factory speaker systems are not capable of loud,
