Installation Precautions/Hints
Do not mount the OVERDRIVE Line Driver where it will be exposed to
outside elements or extreme temperatures. Avoid areas of severe vibration or
shock. The front bumper is off limits.
• Mount the OVERDRIVE as close to the head unit as possible. Absolutely
mount it at the front of the vehicle.
• Use high quality, 100% shielded audio cables.
• Plan on a single-point (star ground) scheme so all components, including the
head unit, connect to a common ground point. Use no less than 14 gauge wire
for the power and ground connections.
• Make certain that there are no fuel lines, brake lines, electrical wires or
anything else that you don’t want to run a drill bit through. That includes things
on the back side of that floor panel you’re about to punch a hole in.
• Make certain the OVERDRIVE is firmly mounted with screws so it won’t
come flying off the next time you blast over a speed bump.
• Adjust the Overdrive for the maximum that the next component in the chain
can handle. Make certain that whatever component you put after the OVER-
DRIVE can withstand the output voltage you dial up. The inputs to many
crossovers and amplifiers will clip around 2 volts. All AudioControl products
can handle inputs from 5 to 9 volt RMS.
• Turn down your amp gains to their minimum setting. Then you can run a
higher signal (better signal to noise) into the amplifiers. Don’t worry, your amps
will still go to full output (unless they actually MUTE when at minimum). For
more information on this, ask us for Tech Note 1006.
Blatant Plug
The OVERDRIVE Line Driver is part of the AudioControl Performance
Match Series of products. The Performance Match products will extract killer
performance from your car stereo system.
There are real world barriers to good autosound such as the fact that doors
and trunks rarely make good speaker boxes. AudioControl Performance Match
products like the Concert Series 2XS
tm
and 3XS
tm
crossovers; the Concert
Series EQL
tm
, EQX
tm
, and EQT
tm
equalizers; and The Concert Series Epicenter
bass maximizer will help you overcome those barriers. AudioControl compo-
nents make it easy to adjust or “voice” components to the specific acoustics and
hostile elements of your stereo system whether it’s a sleek Honda or stylish
ThunderBird. The result is, as one warranty card stated, “A dream come true.”
And now a word from the legal department...
The 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 OVERDRIVE. 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 OVERDRIVE for five years
from the date you bought it, if installed by an authorized Audio-
Control dealer, and will fix or replace it, at our option, during that
time.
Here are the conditions that make this warranty conditional:
1. You have to fill out the warranty card and send it to us within
15 days after you purchase your OVERDRIVE.
2. You must keep your sales slip or receipt so you have proof
when and from whom you bought your OVERDRIVE. We’re
not the only company to require this, so it’s a good habit to be
in with any stereo purchase.
3. Your OVERDRIVE has to have been originally purchased from
an authorized AudioControl dealer. You do not have to be the
original owner to take advantage of the warranty, but the date
of purchase is still important, so be sure to get a copy of the
sales slip from the original owner.
4. You cannot let anybody who isn’t: (a) the AudioControl
Factory; (b) an authorized service center; or (c) someone
authorized in writing by AudioControl service your OVER-
DRIVE. If anyone other than (a), (b) or (c) messes with your
OVERDRIVE, that voids the warranty.
5. The warranty is also void if the serial number has been altered
or removed, or if the AudioControl OVERDRIVE is used
improperly. Now, that sounds like a big loophole, but here is
all we mean by it.
Unwarranted abuse is: (a) physical damage (our mobile
products are not meant to be used as jack stands for your car); (b)
improper connection (we have done the best we can to protect the
inputs, however, 120 volts into the jacks can fry the innards of the
poor beasty); (c) sadistic things.
This is the best mobile product we know how to manufacture,
but if you use it for the front bumper of your Baja bug and get it
full of water and dirt, things will go wrong.
Assuming you conform to numbers 1 through 5, and it isn’t all
that hard to do, we get the option of deciding whether to fix your
old unit or replace it with a new one.
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 OVERDRIVE 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 OVER-
DRIVE.
Failure to send in a properly-completed warranty card negates
any service claims.
