Six Channel Line Output Converter
for interfacing with factory installed audio systems
Greetings from the rainforests of the Pacific Northwest. We would
like to congratulate you on your purchase of the LC6i: a six-chan-
nel, high-performance, line-output converter. This unique product
will accept two, four, or six channels of speaker-level signal from
a factory-installed amplifier or source unit, and convert it to a
high-quality, low-noise pre-amp signal. Therefore the LC6i is an ideal
OEM (Original Equipment Manufacturer) interface component, as it
will allow you to use your factory-installed source unit but give you the
ability to add really good aftermarket amplifier(s) and processor(s).
Whether this is your first product from the rainforest dwellers of Audio-
Control, or you are already a firm believer, you will definitely enjoy how
great the LC6i can make your performance system sound.
Now before you start salivating just thinking about the benefits and all
of the nifty applications for your LC6i, please take a few minutes to sit
back, have a cold beverage, and read through this manual. We always
love to get calls from our customers, but we have tried to answer all of
your questions in this manual. It contains lots of useful facts and infor-
mation - - and besides, we spent a lot of time writing it!
