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

6. Operation works the same as Punch EQ, see below.

NOTE: Connecting the optional remote overrides the Punch EQ

control on the amplifier.

CAUTION:Overexcursion and subsequent damage may occur at high levels of boost.

INFRASONIC FILTER

Placing the switch to "ON" engages a 28Hz infrasonic filter limiting 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

Turning the knob clockwise increases the bass boost from 0 to +18dB @ 45Hz. Set this to your personal preference while listening to the system.

NOTE: Connecting the optional remote overrides the Punch EQ control on the amplifier.

ADJUSTING CROSSOVER FREQUENCY

The crossover frequency can be adjusted between 35-250Hz.The crossover is set to LP (Low Pass) operation only.

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.

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 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.

:Avoid setting the amplifier gain very high as noise and

CAUTION distortion will increase significantly.

NOTE:For a more in depth setting procedure, contact Rockford Technical

Support.
