Six Channel Line Output Converter With Auxiliary Input

G
reetings from the rainforests of the Pacic Northwest. We would
like to congratulate you on your purchase of the LC7, a six-chan-
nel, high-performance, line-output converter with an auxiliary input. This
nifty product will accept two, four, or six channels of speaker-level signal
from a factory-installed amplier or source unit and convert it to a high-
quality, low-noise pre-amp signal. This makes the LC7 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 amplier(s) and processor(s). The LC7 also
has an extra set of RCA inputs that allow you to interface your iPod, MP3
player, satellite radio tuner or other audio source. Turntables are not rec-
ommended. Whether this is your rst product from the rainforest dwellers
of AudioControl, or you are already a rm believer, you will denitely
enjoy how great the LC7 can make your performance system sound.
Now before you start salivating just thinking about the benets and
all of the nifty applications for your LC7, take a few minutes to sit back,
grab a beverage of your choice, and read through this manual. It contains
lots of useful facts and information which will probably answer any
questions you may have. If you are one of those folks who “does not like
to read manuals”, then you will be happy to know that this manual is
very peppy and has lots of pictures.
