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.

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.
