Manual

RCA INPUT, BOTH LOW LEVEL AND HIGH LEVEL.

• The amplifier LEVEL control has sufficient adjustment range for both low level and high level input into the RCA

jacks. A factory source radio that does not have RCA output, using the wires that are connected to the speakers,

can be directly connected to the RCA jacks when the amplifier LEVEL control is adjusted to 8V.

SETTING LEVEL

• Set the amplifier LEVEL control to minimum before you turn on the amplifier for the first time.

• For lowest distortion and lowest noise the ampliﬁer LEVEL should be set at the lowest setting that yields

sufﬁcient loudness without distortion. For lowest noise your source radio volume control should be near

maximum that does not cause distortion.

• To ﬁnd the best ampliﬁer LEVEL setting:

With the ampliﬁer LEVEL at minimum, slowly increase the source radio volume to around 3/4 without distortion.

Then, slowly turn up the ampliﬁer LEVEL control to the maximum desired loudness. Listen very carefully and

turn down the ampliﬁer LEVEL control if you hear any distortion.

FPD 600.4 CONFIGURATION EXAMPLES

4 CHANNEL STEREO NON-BRIDGED

• (SEE GRAPHIC B1)

• If you have four input wires from the source deck, plug them into inputs 1+2 and 3+4.

Set ROUTE switch to 1+2.

• If you have two input wires from the source deck, plug them into inputs 3+4.

Set ROUTE switch to 3+4.

Set the switch to STEREO.

• If you are NOT using a subwoofer set all switches to flat. If you hear distortion in your woofers set all switch to

HP and adjust all HP frequency until the distortion goes away, this will probably be around 50 Hz to 70 Hz.
