Greetings from the rainforest dwellers of the Pacific Northwest. We would like to
congratulate you on your purchase of The Epicenter Plus from AudioControl. As the
name suggests this processor is based on AudioControl's legendary (and patented)
bass restoration circuitry, appropriately named The Epicenter. Whether this is your
first AudioControl product, or you are already a firm believer, the bass restoration
enhancements of The Epicenter Plus will leave you breathless. Extra octaves of deep,
body shivering bass can dramatically increase the enjoyment of your performance
autosound system.
The Epicenter Plus is for audio enthusiasts who want to use their factory-installed
source units so it is equipped with AudioControl's high-impedance, speaker-level
inputs. Additionally, an auxiliary input allows users of factory-installed radios and
portable audio players (like iPods™) to also appreciate the performance of its bass
restoration circuitry.
We are sure that by now the thought of adding The Epicenter Plus to your perfor-
mance autosound system is probably making you salivate. However, we strongly
encourage you to take a few minutes to sit back, grab a beverage of your choice
and read through this manual. Although many autosound enthusiasts feel reading
an "owner's manual" is only for novices, this particular manual may save you some
phone calls during the installation process. It also contains lots of useful facts and
information (and besides, we spent a lot of time writing it)!!
