Anleitung Zusammenfassung


3. Adjusting the Low, 24dB @ 40Hz-200Hz Variable Low Pass X-over Frequency Controls– • Setting for Subwoofers: Using “X-OVER” you have control over what frequency you want your amp to start crossing over your signal. By turning this control all the way counter-clockwise, you are crossing the signal over at 40Hz (the range is counter-clockwise 40Hz to clockwise 200Hz). This means that the amp will send the woofers frequencies from 20Hz to 40Hz and then start to taper down as the frequencies get over 40Hz (24dB/octave roll off). The industry standard for low pass crossover point is right around 90Hz. However, by experimenting with the crossover point (higher or lower) you will find what sounds best in this install. The decibel per octave roll off (dB/oct) means how fast the amplifier tapers down as the frequencies get higher. This amp uses a 24 decibel per octave roll off, which is pretty steep, or tapers off fairly quickly from the crossover point. This design complements both the subwoofer and mids to provide greater musical detail. 4. Setting the 20Hz–50Hz, 12dB Variable Subsonic Filter – This feature will help remove some of the potentially damaging low frequencies from your subwoofer system. By turning this control all the way counter-clockwise you are limiting the signal below 20Hz. By turning this control all the way clockwise you are limiting the signal below 50Hz. Start at 20Hz and adjust this feature until your bass response sounds smooth and detailed. 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 and as a general rule of thumb, start tuning with a “Q” setting below “2”. Higher “Q” values are rarely needed unless there is some truly 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. 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 amplifier. Note: One Remote Subwoofer Level Control can control two or more amplifiers using a mini plug Y-adapter. 7. Setting the Phase – Depress the PHASE button to ensure the subwoofer interacts correctly between the mid- bass or midrange speakers. The PHASE button is located in the PROCESSOR section of the control panel. Whether you want the position of the phase at 0 degrees or 180 degrees will be determined once you hear your audio system produce smooth, tight and louder bass. You need to try both 0 and 180 positions to hear the difference. 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 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 Pot 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 t...
