There are two sets of RCA INPUTS on the front end of your amplifier.
Plug the RCA cables from your head unit into the appropriate set of
inputs, front and rear. 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 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.
