with a maximum panel thickness of
3/8". Ensure there is enough room
within the panel area for connection.
7. Route the cable through the hole and connect to
the remote.
8. Press the remote into the panel cutout until it clicks
in place.
Operation
9. Turn clockwise to add Punch to amplifier bass
frequencies.
CAUTION:Overexcursion and subsequent
damage may occur at high levels
of boost
NOTE:An optional Para-Punch Remote Bass is available
which adds an adjustable center frequency
control with the adjustable boost control.
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
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.
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.
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.
