5. Remote Subwoofer Level Control (Remote Gain) – Let’s say the amplifier’s gain is set at halfway, when the
remote subwoofer level control is plugged in, you now have external control of the gain from zero to halfway.
The installation of this level control is NOT necessary to get full power from the amplifier.
6. Prizm EFX – Now that you have completed adjusting all your amplifier settings, you can set the lighting effects
to your personal taste.
• Selecting Colors: You can change the backlit colors simply by turning the dial labeled PRIZM COLOR,
located in the MTX PRIZM EFX section of the control panel, left or right. Starting at the left most position, the
colors range from RED to GREEN, BLUE, and then RED again. You can choose any color in between making
the combinations unlimited.
• Selecting the EFX Feature: You can switch Prizm EFX lighting to “pulsate” with the beat of the music.
Simply Depress the button labeled PRIZM EFX located in the in the MTX PRIZM EFX section of the control
