Speaker-Level Inputs
The LC7 is designed to accept an amplified, speaker-level signal from
a factory source unit or amplifier. You will want to refer to a factory
service manual or wiring-harness schematic to determine which wires
are the speaker wires for your system. If you are unsure which wires
are the speaker wires, it is recommended you look at the color of the
speaker wire connected to the speakers and follow them back to the fac-
tory source or amplifier. Connect the speaker wires to the Speaker-Level
Inputs on your LC7. Make sure to get your "pluses" and "minuses" con-
nected properly.
Auxiliary Input
Many car audio enthusiasts have a number of sources of music, above
and beyond their factory-installed source unit. Downloading music from
the Internet onto an iPod or an MP3 player is getting more and more pop-
ular. By last count there were only 100,000,000 users! To help interface
one of these audio devices, the LC7 is equipped with two-channel audio
input. To trigger this input, you need to tap the dash control auxiliary
knob and the LC7 will switch between the main inputs and this auxiliary
input. A bright LED indicator on the LC7 chassis will identify which
source unit is being used. On this topic, the LC7 provides you with a
level control for your auxiliary source which allow you to match the sig-
nals between your main source and your auxiliary. That way, when you
switch between your iPod and the main radio inputs, the volume level
won't blow your ears off.
Pre-Amp Outputs
Connect good quality RCA connectors from these outputs to the inputs
of your amplifiers. While we won't get into the discussion as to whether
plutonium cables, sound better than un-obtainium cables we will tell you
that well-constructed cables are less problematic in a rugged environment
like your car system.
