OPERATION
ADJUSTING GAIN
Do the following individually for each channel.
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
Do the following individually for both front and rear if used.
Placing the switch in the HP position sets the amplifier to the High Pass mode, enabling fequencies
above the cut-off point to pass, adjustable between 50-250Hz.
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 fequencies
below the cut-off point to pass, adjustable 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.
