O
PERATION

ADJUSTING GAIN

1.Turn amplifier gains to minimum (counter-clockwise).
2.Turn the source unit volume up to 7/8 maximum (or when distortion is just inaudible).
3. Slowly increase amplifier gain control until adequate volume is achieved.
NOTE: Best signal to noise and dynamic range are realized with gain set to minimum. For a more in
depth setting procedure, contact Rockford Technical Support.
CAUTION: Avoid setting amplifier gain high as noise and distortion will greatly increase.

ADJUSTING CROSSOVER FREQUENCY

The crossover frequency can be adjusted between 50-250Hz.The crossover is set to LP
(Low Pass) only. Turn the crossover adjustment to minimum. With the system playing,
turn the crossover adjustment knob up slowly until the desired crossover point is
achieved. A good place to start is 80Hz.

INFRASONIC FILTER

The variable 15-40Hz 12dB/octave infrasonic filter limits the amount of low frequency
information going to the woofer. Set this to your personal preference while listening to the
system one way, then the other.
NOTE: We recommend using the infrasonic filter when using vented enclosures with
this amplifier.

PUNCH EQ

This works along with the crossover switch on the
amplifier. When set to Low-Pass (LP) operation, this
is a variable Bass Boost. Set this to your personal
preference while listening to the system.
CAUTION: Overexcursion and
subsequent damage may
occur at high levels of
boost.

REMOTE PUNCH LEVEL CONTROL

When connected, the "Gain Control" is linked and allows you to remotely control the output level of the
amplifier from the dash or center console.
