bass gain module (only works when crossover is set

to LP). Set GAIN (6) to max when using the remote.

When the CROSSOVER MODE is set to HP it filters out bass from your midrange or full range speakers. That takes strain off the speakers, allowing them to play louder with less distortion. Set the Frequency Control to around 80Hz – 100Hz. If it sounds like you're losing too much mid-bass punch, turn the Frequency Control

2 CROSSOVER MODE SELECTOR SWITCH

A] set to LP position when the amplifier is used to drive a

subwoofer. The frequencies above the crossover point will

be attenuated at 18dB/Octave. B] set to OFF position

when the amplifier will be used to drive full range speak-

ers with no subwoofer in the system. The full frequency

bandwidth will be output to the speakers with no high or

low frequency attenuation. C] set to HP position when the

amplifier is used to drive full range speakers with a sub-

woofer in the system. The frequencies below the crossover

point will be attenuated at 18dB/Octave.

3 CROSSOVER FREQUENCY

ADJUSTMENT

The crossover frequency adjustment filters out

frequencies that you don’t want the speaker to reproduce.

When the CROSOVER MODE is set to LP it filters out the

midrange and high frequencies from the subwoofer. If

it is set too high, you’ll hear voices and other midrange

sounds coming from the subwoofer and the bass will

seem to come only from the rear of the vehicle. If it is set

too low, you’ll miss the “kidney punch” kick of the mid-

bass. Set the control to 80Hz – 120Hz and adjust it by ear

from there.

down to 50Hz.

When the CROSSOVER MODE is set to OFF, the Frequency Control does nothing.

4POLK/MOMO PRE-EQ SWITCH

One-button preset EQ delivers enhanced performance when used with Polk/MOMO Subwoofers (when CROSSOVER MODE SELECTOR SWITCH is set at “LP”) and Polk/MOMO full-range speakers (when CROSSOVER MODE SELECTOR SWITCH is set at “HP”). Pre-EQ switch is defeated when the CROSSOVER MODE SELECTOR SWITCH is set at “OFF”.

5INPUT TYPE SELECTOR

Select the type of connections made: LOW “line” level RCA connections, or HIGH level speaker wire connec- tions. Default position is LOW, as the most popular head unit output connections are RCA. To use HIGH level speaker wire inputs, simply attach an RCA connector to your speaker wire, and move this switch to HIGH.

6GAIN ADJUSTMENT

Begin with gain set at about the 11 o’clock position. Once all settings are made, turn this setting up until your source JUST BEGINS to distort, then back off slightly to cut distortion and operate at optimum gain.
