OPERATION

ADJUSTING GAIN

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.

NOTE:Best signal to noise and dynamic range are realized with the gain at minimum.

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 crossover switch in the HP position sets the amplifier to the 80hz High Pass mode, enabling frequencies above the cut-off point to pass.

Placing the crossover switch in the AP position sets the amplifier to the All Pass mode, preventing any crossover adjustment, allowing all frequencies to pass.

Placing the crossover switch in the LP position sets the amplifier to the Low Pass mode, enabling frequencies 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.A good place to start is at about 80Hz.

PUNCH BASS

The Punch Bass control is a narrow band adjustment at 45Hz variable from 0dB to +12dB.
