CROSSOVER AND FILTER ADJUSTMENTS

The crossover and filter gain adjustments can be performed two different ways, by using a piece of audio test equipment called an RTA (Real Time Analyzer) or by listening to a familiar piece of music. The RTA is most commonly used to achieve the flattest possible system response in preparation for a sound off competition. Although an RTA may help in setting a flat system response it does not ensure the unit is tuned for your personal listening preferences. When setting the 2500 filter and gain controls using a familiar piece of music, adjustments can be made according the way you like the music to sound in relation to the vehicles acoustics and the type of drivers in the system.

1.Leave the subwoofer controls and the five filter gain controls to the flat (center) position.

2.If the dedicated subwoofer output is being used, turn off any active

subwoofer crossovers in the subwoofer amplifier.

NOTE:

When interfacing with Directed class d amplifiers

 

with non-defeatable Low-pass crossovers adjust

 

the amplifiers crossover point to its highest

 

frequency setting.

3.Adjust the crossover point and subwoofer volume using the subwoofer controls (knobs four and five on the front panel) so the subwoofer blends with the satellite speakers. When set properly the bass should not be localized and voices should not be heard through the subwoofers.

4.Fine tune the system sound using the subwoofer volume control and the five filter gain controls for different tastes or audio material.

5.After adjusting the system for the best sound quality use the equal- izers master volume to adjust overall volume of the system.
