OPERATION
ADJUSTING CROSSOVER
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 80Hz Low Pass
mode, enabling frequencies below the cut-off point to pass.
VARIABLE HIGH LEVEL ADJUSTMENT
The variable high level adjustment can be used to delay the turn on eliminating induced noise,
turn on/off pop.
In a high level(speaker) input application, utilizing a 6V DC(Direct Current) offset
voltage, the Punch Boosted Rail amplifier can be turned on/off allowing the REM to be
used as an output to turn on/off an amplifier or other accessory.
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. Most users find adequate
gain and volume is achieved at about halfway in the adjustment range.
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.
