Audio Control EQS Owner's Manual page 5

Speaker Level Inputs: If you are like many people and
like the look and features of your factory installed source
unit but feel it's lacking power and bass, we have good news.
The EQS has a unique high impedance speaker level input
that will interface with most factory installed source units
(even Bose) and let you add amplifiers and speakers to your
hearts content. However, unlike some of the cheesy speaker
level line output converters available, the EQS offers a very
high fidelity sound quality input.
PFM Subsonic Filter: This unique feature is legendary
with many AudioControl fanatics for it's ability to fine-tune
the bass response of any system. Why waste power on nasty
subsonic information when your Programmable Frequency
Match (PFM) filter will help you clean things up.
Bulletproof Warranty: The most important feature
of all. Every AudioControl product is
selflessly designed and
manufactured by the
occupants of our
Owner's Enjoyment Manual
rainforest factory. We take every effort to ensure that you
will have many years of enjoyment out of your EQS. To
ensure the performance of your new toy, we highly recom-
mend 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 your
EQS should stop working, we will back it with a limited five
years parts and labor warranty. Should you choose to install
it yourself we will still give you 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 EQS
"disappear" one day while your car is parked at your local
latte' stand, you will find insurance companies very unfor-
giving without proof of purchase.
