There is a pair of RCA inputs on the front end of your amplifier.
The RCA cables from your head unit or crossover plug in here.
If your head unit doesn't have RCA outputs don't worry. Simply
add a set of RCA plugs (available at your dealer) to your front
or rear set of speaker leads (see drawing below), plug them
into the input jacks, and push in the -12dB input attenuation
switch.
Balanced Differential Inputs
This circuitry reduces noise radiated into your
signal cables by up to 40dB. This is equivalent to a noise
reduction of approximately one hundred times what the noise
level would be without this circuitry. It provides all the benefits
of a true 'balanced' line without the need of any special cables
(see diagram below). This type of input works with any
conventional RCA cable.

WARNING:
If you are using a source unit with bridged high powered (or
"floating ground")
speaker outputs, a suitable high to low level adapter
must be used. If you are unsure about your head unit see your local
PrecisionPower dealer or call 1-800-62Power.
