OPERATION

OPERATION

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.

ADJUSTING CROSSOVER FREQUENCY CAUTION:Avoid setting amplifier gain high as noise and distortion will greatly increase.

ADJUSTING CROSSOVER FREQUENCY

The crossover frequency can be adjusted between 40-130Hz.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.

PHASE SWITCH

Allows you to conveniently switch the output phase of the amplifier between 0° and 180°. This has the same effect as physically reversing the Positive (+) and Negative (-) speaker wires.

PUNCH BASS

This is an adjustable Bass level control centered at 45Hz @ 12dB/octave.

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.

Mounting and installation

1.Find a location, either under the dash or near the center console, that gives easy access to adjust.

2.Install the mounting clip using the screws supplied.

3.Route the cable from the remote and connect to the amplifier.

4.Slide the remote housing onto the mounting clip until it snaps into place.
