ADJUSTING CROSSOVER FREQUENCY
Placing the crossover switch in the HP position sets the amplifier to the High Pass mode,
enabling frequencies above the cut-off point to pass, adjustable between 50-500Hz.
Placing the crossover switch in the AP position sets the amplifier to the All Pass mode,
pre venting any cr osso v er 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 50-500Hz.
Turn the crossover adjustment knob to the minimum setting.With the system playing, turn the crossov er
adjustment knob up slowly until the desired cr osso v er point is achiev ed.
VARIABLE HIGH LEVEL ADJUSTMENT
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 a n amplifier
or other accessory.
The variable high level adjustment can be used to delay the turn on eliminating induced noise,
turn on/off pop.
ADJUSTING GAIN
To adjust the gain setting, turn the amplifier gains all the wa y 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 sour ce 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 achiev ed at about halfwa y in the adjustment range.
CA UTION:A void setting the amplifier gain very high as noise and distortion will increase
significantly.
NOTE: For a more in depth setting procedur e, contact Rockfor d Technical Support.

OPERATION
REMOTE PUNCH EQ (Option)
NOTE: Previous (prior to 2007) Punch Bass and Para-Punch
remotes will not work with these amplifiers.
NOTE:Use the instructions that came with the remote for a
variety of mountings that fit your preference.
Quick Install
1. Using the screws supplied, install the mounting clip.
2. Slip the remote onto the mounting clip until it snaps into
place.
3. Route and connect the cable to the remote and amplifier.
Operation
4. This works along with the crossover switch on the amplifier.
When set to Low-Pass (LP) operation, this is a variable Bass Boost.
When set to High-Pass (HP) operation, this is a variable Mid-Bass and Treble Boost.
When set to All Pass (AP) operation, both the Bass and Treble frequencies are boosted.
Set this to your personal preference while listening to the system.
CAUTION: Overexcursion and subsequent damage may occur at high levels of boost.
