INSTALLATION
1. Read this manual carefully and in its entirety before installing this
equalizer.
2. Always disconnect the battery or remove the fuses for circuits you
will be working on.
3. Check for clearance of any hazards such as wiring harnesses or
heater core before mounting the equalizer to any panels in the
vehicle.
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 ground and any moving parts that
can tangle the wires such as heater controls or wiper motors.
6. Route all power and signal cables as far as possible from other
vehicle wiring harnesses. Loom when appropriate.
7. It is recommended that the equalizer be grounded directly to the
chassis of the Source 1 head unit. The Source 1 head unit should be
grounded at a chassis point (preferably bare or scraped sheet metal)
other than the factory head unit ground wire or under dash brackets.
8. Use only the supplied machine screws to mount the equalizer or
damage to the circuitry could occur.
CONTROL PANEL FEATURES
Adjustment Knobs
The PAR-650 five-band parametric equalizer features dual-function control knobs
that extend when needed for adjustments and retract when not in use, allowing
full adjustability with minimum control panel clutter. When the knobs are extended
for adjustment they have an in and out position that allows each knob to control
multiple processor settings.

1.
Remote Turn On Output - This output is intended to be the remote turn
on for the system amplifiers and has a built-in delay.Two to three seconds
after the PAR-650 receives a (+)12V turn on signal it will send a (+)12V
turn on signal to the amplifiers. This feature is designed to eliminate
system turn-on pops that can occur when several components turn on at
the same time.
2.
3.
(+)12V Constant Power - This is the main power input for the PAR 650
and must be connected to a (+)12V constant power supply. DO NOT
connect this to a switched 12V source or the system may pop when the
key is turned off.
RemoteTurn On Input - This is the input for turning on the PAR 650 and
system amplifiers. It should be connected to the (+)12V remote turn on
output of the system head unit. The PAR 650 has a built in turn off delay
to prevent turn-off pops. When the remote turn on signal from the head
unit shuts off, the amplifiers will turn off immediately and the PAR 650 will
stay on for five seconds before turning off. This feature is designed into
the PAR 650 to eliminate system turn off pops that can occur when
several components turn off at the same time. DO NOT connect this to a
(+)12V constant power supply.
4.
Ground - Connect this terminal to a quality ground location, preferably
the chassis of the head unit, which must itself be properly grounded to the
vehicle chassis. It is not recommended that the factory radio ground be
used for after market audio components.

components. Never replace this fuse with one of higher value or damage
to the PAR 650 could occur and result in loss of your warranty.
Illumination Switch - This switch changes the front panel background
lighting from BLUE to GREEN to match the vehicle dash or radio
backlighting.
High Pass Output Switch - This switch controls whether the front and
rear outputs are full range or crossed over as high pass outputs to the
amplifiers. When set to high pass output the front and rear output
crossovers are separately variable from 30 to 400Hz, by using the high
pass frequency control knob (#5) on the front panel.

4
Set the filter gains to the flat (center) setting.
Complete all signal and power connections to the PAR-650.
5
Turn the system on and increase the gain on the Source 1 inputs until
audible distortion can be heard. The system should be very loud at this
time.

7
Reduce the PAR-650 master volume level and test for well-balanced and
linear volume adjustment when using the Source 1 volume control.
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.
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 allow for
your personal listening preferences. When setting the EQ 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.
Set all filter gain controls to their flat setting by adjusting all the filter
knobs to the center or 0 setting when they are extended and set to their
in position.
2.
Set all frequency controls to their flat setting by adjusting all the filter
knobs knobs to the flat or 0 setting when they are extended and set to
their out position.
3.
If using the dedicated subwoofer output, set its gain and frequency
control to the center position.
NOTE: When interfacing PPI class of amplifiers with non-defeatable low-
pass crossovers adjust the amplifiers crossover point to its highest
frequency setting.
4.
Turn on the head unit and play a familiar piece of music as reference
material.

7.
If the front and rear outputs have been set to high pass by setting the
switch on the rear panel to the high pass setting, adjust the front
crossover to the lowest possible setting with a minimum of distortion.
Repeat for the rear speakers.
At this time adjust the subwoofer frequency and volume to match the
crossover settings for the satellite speakers. When set properly the bass
should not be localized and voices should not be heard through the
subwoofers.
Adjusting the frequency control knobs out direction from center will
change the center frequency and bandwidth parameter for that
particular filter.The higher the frequency (clockwise) for a filter the wider
bandwidth, the lower the frequency (counter-clockwise) the narrower
bandwidth.
8.
Once the center frequencies and bandwidth have been adjusted
controls have been set, use the filter gains (filter knob’s in position) to
fine tune the system for differing tastes in music or material.
