The purpose and benefit of the D’Amore
Engineering / SMD Crossover Calibrator.
The purpose of this tool is to enable the installer to set
the crossover frequency of an electronic crossover to the
desired frequency, accurately and quickly. It can also be
useful for matching gains on multiple amplifier
competition type systems.
What is included?
The Crossover Calibrator (CC-1)
Protective silicon rubber boot
2 Calibrated Test tone CDs
Harness
This manual
Pride of ownership

About the design
When you pick up the CC-1, know that you are holding a
precision piece of equipment. If treated as such it
should provide you with many years of reliable service.
We have chosen a 9V battery as a power source for a
few reasons:
They are readily available
Isolating the CC-1 from the vehicle’s electrical
system for power, guarantees that it will only
measure what it is supposed to measure; the
audio signal, not noise in the charging system
We also chose an RCA input connector for a few
reasons:
It makes it pretty easy to measure the output of
a headunit directly, if you choose to do so
Should the harness become damaged it is easily
replaceable or repairable in the field
Specifications
Everyone hides these in the back of the book. We are
proud of our specs, they aren’t lies, so we are putting
them up front.
The Crossover Calibrator’s circuitry is computer
controlled
Crossover point accuracy +/- 0.10dB
Gain matching accuracy +/- 0.05dB
Low Battery LED = battery voltage < 6.5Vdc
Auto-shut off timer 8 - 10 minutes after ON
button is pressed

Power requirements
Pull the silicon rubber boot off of the unit by starting at
one end and pulling off towards the other end. On the
back side you will see the battery compartment. Slide
battery compartment cover off towards bottom end of
unit to reveal the 9V battery compartment. Insert a fresh
9V battery, make sure the wires are routed around the
battery. (If they are under or on top of the battery the
door may not close properly) You are ready to go. When
the low battery LED is illuminated, the tool will become
inaccurate. Replace with a fresh battery as soon as
possible.
Do not run this unit off of any power source other
than a 9V battery. Wall adapters are electrically
noisy, as are vehicle electrical systems.

Setting a Low Pass Crossover
1. This procedure will set the Low Pass Crossover
frequency to a desired set point. This is
accomplished by setting the bass, treble, etc, to
zero; and any EQs and crossovers in the
headunit to flat. When finished, you can reset
the bass, treble, EQ, etc. as desired.
2. Connect the CC-1 to an electronic crossover’s
outputs by plugging an RCA from the
crossover’s outputs to CC-1’s input or use the
included harness to connect the CC-1 to the
amplifier’s speaker outputs; Red to speaker (+)
and Black to battery ground. Note: On some
amplifiers the right channel’s output may actually
be on the speaker (-) terminal. In this case,
connect Red to speaker (-) and Black to battery
ground.
3. If the unit is already on, switch the CC-1 off by
holding the OFF button for 1 second. (This
must be done to initalize the program mode)
Now switch CC-1 power on by pressing the ON
button.
4. Set the source unit’s volume to zero.
5. Select the track on the CD that corresponds to
the desired crossover frequency. Play track on
repeat. (Track list on page 16)
6. Set the crossover switch to off (all pass, full
pass, full range etc.) Skip to step 8.
7. If the crossover cannot be turned off (full range)
turn the crossover frequency to its highest
setting.

7
8. Turn up the source unit volume until you see the
Signal LED illuminate green. If the LED turns
Red, this indicates the volume is too high. Turn
volume down until the LED remains green.
9. When the Signal LED remains Green, press the
READ button.
10. Set crossover switch to Low Pass if it has one.
11. Using the LEDs at the top of the CC-1, slowly
turn the crossover frequency adjustment pot
until the CALIBRATED LED illuminates.
12. Congratulations, you have just set the crossover
frequency perfectly!

Setting a High Pass Crossover
1. This procedure will set the High Pass Crossover
frequency to a desired set point. This is
accomplished by setting the bass, treble, etc, to
zero; and any EQs and crossovers in the
headunit to flat. When finished, you can reset
the bass, treble, EQ, etc. as desired.
2. Connect the CC-1 to an electronic crossover’s
outputs by plugging an RCA from the
crossover’s outputs to CC-1’s input or use the
included harness to connect the CC-1 to the
amplifier’s speaker outputs; Red to speaker (+)
and Black to battery ground. Note: On some
amplifiers the right channel’s output may actually
be on the speaker (-) terminal. In this case,
connect Red to speaker (-) and Black to battery
ground.
3. If the unit is already on, switch the CC-1 off by
holding the OFF button for 1 second. (This
must be done to initalize the program mode)
4. Now switch CC-1 power on by pressing the ON
button.
5. Set source unit’s volume to zero. Select the
track on the CD that corresponds to the desired
crossover frequency. Play track on repeat.
6. Set the crossover switch to off (all pass, full
pass, full range etc.) Skip to step 8.
7. If the crossover cannot be turned off (full range)
turn the crossover frequency adjustment to its
lowest setting.

8. Turn up the source unit volume until you see the
Signal LED illuminate green. If the LED turns
Red, this indicates the volume is too high. Turn
volume down until the LED remains green.
9. When the Signal LED remains Green, press the
READ button.
10. Set crossover switch to High Pass if it has one.
11. Using the LEDs at the top of the CC-1, slowly
turn the crossover frequency adjustment pot
until the CALIBRATED LED illuminates.
12. Congratulations, you have just set the crossover
frequency perfectly!
Setting a Subsonic (Infrasonic) Filter
1. This procedure will set the Subsonic…. rant
mode on…. (Infrasonic is the correct term –
which literally means a sound that has a
frequency that is lower than a human can hear.
Subsonic: A speed or velocity which is slower
than the speed of sound.) ….rant mode off….Ok
this procedure will set the Infrasonic Filter
frequency to a desired set point. This is
accomplished by setting the bass, treble, etc, to
zero; and any EQs and crossovers in the
headunit to flat. When finished, you can reset
the bass, treble, EQ, etc. as desired.

4. Set the source unit’s volume to zero.
5. Select the track on the CD that corresponds to
the desired crossover frequency. Play track on
repeat. (Track list on pages 16, 17)
6. Set the Infrasonic Filter to off or defeat. Skip to
step 8.
7. If the Infrasonic Filter cannot be turned off, turn
the Infrasonic Filter frequency to its lowest
setting.
8. Turn up the source unit volume until you see the
Signal LED illuminate green. If the LED turns
Red, this indicates the volume is too high. Turn
volume down until the LED remains green.
9. When the Signal LED remains Green, press the
READ button.
10. Set the Infrasonic Filter switch to on if it has one.
