CONTROL PANEL FEATURES
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.
NNOOTTEE::
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.
