This means that the amp will send the components or separates frequencies from 40Hz to 20kHz and then start to taper down as the frequencies get under 40Hz (octave roll off). The industry standard for high pass setting or X-over point is around 120Hz. When the amp is in HP setting and the X-over point is set to 120Hz, the amp is sending the speakers frequencies from 120Hz to 20kHz. This crossover network allows the drivers to recreate the frequencies within a precisely designed range so that the speakers do not become distorted by trying to reproduce frequencies that they are physically unable to reproduce. This feature ensures that the components or separates do not receive low bass notes. The 12dB/oct means the slope, or the amount of other frequencies that will be affected, is fairly narrow. This design complements both the subwoofer and the mids to provide greater musical detail. • Setting for Full Range (No Crossover): To disable the electronic crossover, select the “OFF” position of the X-OVER switch. This setting will allow the amplifier to play all frequencies. 4. Setting the 30Hz, 12dB Fixed Subsonic Filter – First enable the Subsonic Filter by selecting the “ON” position of the SUBSONIC FILTER switch. This feature will help remove some of the potentially damaging low frequencies of 30 Hz and below from your subwoofer system. Use this feature if the subwoofer breaks up at lower frequencies. 5. Adjusting the Parametric Equalizer – In some applications, the bass amplifier needs some help in boosting or cutting certain frequencies. A parametric equalizer is distinguished from a conventional equalizer circuit in that it allows the user to control the level of the boost or cut as well as the center frequency and the bandwidth of the boost or cut (the range of frequencies affected). The following steps describe what each of the three controls of the parametric Bass EQ do in isolation. It is important to understand these behaviors, because they must all be considered when setting up the EQ. • Setting the “Q”: The “Q” feature can be adjusted to affect a range of frequencies from as wide as 0.5 to as narrow as 4.0. As a general rule of thumb, start tuning with a “Q” setting below “2”. Higher “Q” values are rarely needed unless there is some bizarre acoustic problem in the system. Lower “Q” values give you a broader (and usually more natural-sounding) effect. A “Q” of “1.6” (10 o’clock setting) is a good starting point. • Setting the Frequency: Begin listening for the loudest musical spot or range within the bass range of your sound system. Adjust the center frequency to match this point. For most systems, the best center frequency adjustment will be between 40-50Hz. Use 45Hz (12 o’clock setting) as a starting point and adjust up or down gradually. • 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 CUT 200Hz up to 15dB. This allows you to remove the 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 Y-adapter. 8. 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.
