•Setting the Boost/Cut: Once you determined the loudest musical spot or range within the bass range of your sound system, start cutting until the response is smooth and even. You can also boost low spots within the musical range, but don’t go crazy with the boost knob. There is a lot of boost available, 12dB, but begin with a low boost setting (around 3dB) and try to stay below 6dB whenever possible. Remember that for every 3dB of additional boost you dial in, you are asking the amplifier to double its power output for a given signal in the boost region.
6.Adjusting the Active Resonance Control (A.R.C.) Feature – This feature will be needed when mounting speakers lower in the door or in kick panels. Most vehicles have a natural peak that occurs at about 200Hz. By turning the Pot located on the top control panel clockwise you to CUT 200Hz up to 15dB. This allows you to remove unwanted peaks in your mids and highs that occur in most vehicles.
7.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 have external control of the gain from zero to halfway. The installation of this level control is NOT necessary to get full power from amplifier.
Note: One Remote Subwoofer Level Control can control two or more amplifiers using a mini plug
8.Processor Bypass – The “PROCESSOR BYPASS” switch has two modes of operation, on or off. If the switch is set to “ON” position, all crossover filters and EQ controls are bypassed, leaving only the operation of the gain control adjustments. If the switch is set to “OFF” position, all crossover filters and EQ controls are enabled.
9.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.
