OPERATION
ADJUSTING GAIN
To adjust the gain setting, turn the amplifier gains all the way down. 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 two thirds all the way up on most source units. Next, turn the amplifier gain setting until once
again distortion is audible and then back it down until the distortion is inaudible. Rockford Fosgate
source units do not distort, so the volume can be used at maximum setting.
NOTE: For a more in depth setting procedure, contact Rockford Technical Support.
ADJUSTING CROSSOVER FREQUENCY
Placing the switch in the AP position sets the amplifier to the all pass frequency mode, preventing
any crossover adjustment.
Placing the switch in the LP position allows the crossover frequency to be adjusted between
50-250Hz.
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.
