Make sure the main Source 1 unit is connected to the Source 1 inputs, then adjust the main source units volume to just below maximum. 2. Adjust the Source 1 input gains (top of unit) to the minimum setting and the 2500 master volume control to the maximum setting. N NNO OOT TTE EE: ::If connecting more than one input source to the 2500, use the Source 1 gain controls to match the input level of both sources. 3. Set the subwoofer controls and filter gain controls to the flat (center) setting. 4. Complete all signal and power connection to the 2500. 5. Turn the system on and increase the gain on the source one inputs until audible distortion can be heard. The system should be very loud at this time. 6. Reduce the 2500 master volume level and test for well balanced and linear volume adjustment when using the 2500 master volume control. 7. When connecting a second source unit to the Source 2 input, the source one input gains (top of unit) may need further adjusting to achieve a close signal level match. © 2002 Directed Electronics, Inc 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 CONTROL PANEL FEATURES 1.

To extend and retract the knob, press and release it into the subwoofer crossovers in the subwoofer amplifier. N NNO OOT TTE EE: ::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 equalizers master volume to adjust overall volume of the system. control panel; it will extend or retract with each press. V VVo ool llu uum mme ee - The master volume/fader control knob is set to the volume position when it is initially extended.
