ADJUSTING GAIN

Do the following individually for each channel.
To adjust the gain setting, turn the amplifier gains all the way down (counter-clockwise).Turn the source unit
volume up until distortion is audible and then turn it down a bit until the distortion is inaudible.This will be
about all the way up on most source units. Next, increase the amplifier gain setting until adequate volume is
achieved. Rockford Fosgate source units do not distort, so the volume can be used at maximum setting.
NOTE:Best signal to noise and dynamic range are realized with the gain at minimum. Most users find
adequate gain and volume is achieved at about halfway in the adjustment range.
CAUTION:Avoid setting the amplifier gain very high as noise and distortion will
increase significantly.
NOTE:For a more in depth setting procedure, contact Rockford Technical Support.

ADJUSTING CROSSOVER FREQUENCY

Do the following individually for each channel.
Placing the switch in the HP position sets the amplifier to the High Pass mode, enabling frequencies above
the cut-off point to pass, adjustable between 40-400Hz in x1 mode or 400-4000Hz in x10 mode.
Placing the switch in the AP position sets the amplifier to the All Pass mode, preventing any crossover
adjustment, allowing all frequencies to pass.
Placing the switch in the LP position sets the amplifier to the Low Pass mode, enabling frequencies below
the cut-off point to pass, adjustable between 40-400Hz in x1 mode or 400-4000Hz in x10 mode.
Turn the crossover adjustment knob all the way down.With the system playing, turn the crossover
adjustment knob up slowly until the desired crossover point is achieved.
FREQUENCY MULTIPLY SWITCH (Crossover)
Do the following individually for each channel.
This switch sets the multiplier for the crossover frequencies.
Placing the switch in the x1 position (Out Position) sets the adjustable crossover frequency to 40-400Hz.
Placing the switch in the x10 position (In Position) sets the adjustable crossover frequency to 400-4000Hz.

If you are unsure as to the correct setting of this feature, consult your local Authorized Rockford Fosgate
dealer for the correct recommended setting for your specific system.
When in doubt, select the 24dB setting.
