WARNING
High-powered car audio
systems may produce
sound pressure levels that exceed the
threshold at which hearing loss may
result.
They may also impair a driver’s ability to
hear traffic sounds or emergency vehi-
cles. Use common sense and practice
safe listening habits when listening to or
adjusting your audio system.

INSTALLATION GUIDELINES
1. Read this manual carefully and in
its entirety before installing this
equalizer.
ground and moving parts that can
tangle the wires such as heater
controls or wiper motors.
2. Always disconnect the battery or
remove the fuses for circuits you
will be working on.
6. Route all power and signal cables
as far as possible from other vehicle
wiring harnesses. Loom when
appropriate.
3. Check for clearance of any hazards
such as hoses, heater core, or brake
lines before mounting the equalizer
to any panels in the vehicle.
7. It is recommended that the equal-
izer be grounded directly to the
chassis of the Source 1 head unit.
The Source 1 head unit should be
grounded at a chassis point (prefer-
ably scraped sheet metal) other
than the factory head unit ground
wire or under dash brackets
4. Mount the equalizer in a location
that is easy to access and won't be
distracting to vehicle operation
while making adjustments.
5. Route all power wires and audio
cables away from sharp metal
edges that can cause shorts to
8. Use only the supplied machine
screws to mount the equalizer or
damage to the circuitry could occur.

INTIIAL SETTINGS
1. 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.
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.
2. Adjust the Source 1 input gains
(top of unit) to the minimum
setting and the 2500 master
volume control to the maximum
setting.
6. Reduce the 2500 master volume
level and test for well balanced and
linear volume adjustment when
using the 2500 master volume
control.
NOTE:
If connecting more than one input source to the
2500, use the Source 1 gain controls to match
the input level of both sources.
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.
3. Set the subwoofer controls and
filter gain controls to the flat
(center) setting.
4. Complete all signal and power
connection to the 2500.

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.
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.
1. Leave the subwoofer controls and
the five filter gain controls to the
flat (center) position.
5. After adjusting the system for the
best sound quality use the equal-
izers master volume to adjust
overall volume of the system.
2. If the dedicated subwoofer output is
being used, turn off any active
