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

panel to turn this feature on or off.
