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.

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.
9
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.

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,

Matching the gains of mulitiple amplifiers.
This procedure requires the CC-1 to be placed in a
special mode reserved for SPL competitors and
audiophiles.
1. 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.
2. Disconnect the harness to make sure there is no
signal being applied to the CC-1 and that the
Signal LED is NOT illuminated.
3. Press and hold the READ button for 3-5
seconds or until the Set LEDs start flashing.
Release Set button. CC-1 is now in
competition mode!!
4. Next you need to connect the CC-1 to the
“Master” amplifier’s outputs. Use the included
harness to connect to amplifier’s outputs; Red to
speaker (+) and Black to battery ground.
12
5. Set the source unit’s volume to zero. Select the
track on the CD that corresponds to the desired
frequency you wish to match gains at. If you
don’t know which frequency to use try 40 Hz
(track 10 Disc A) if it is a subwoofer amplifier, or
1 kHz (track 8 Disc B) if it is a full range
amplifier. Play track on repeat.
6. Continue by turning 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 LED remains
green.
7. When Signal LED remains Green, press the
READ button. The Blue Calibrated LED should
illuminate.
8. Now without touching any adjustments on
anything, connect the CC-1 to the output of the
next amplifier that you wish to match it’s gain to
the first amplifier.
9. The LEDs will indicate if the gain is too high or
too low compared to the “Master” amplifier.
10. Adjust gain on the amplifier that the CC-1 is now
connected to until the Calibrated LED
illuminates. The amplifier’s gain is now matched
to the Master amplifier’s gain within +/- 0.05dB !!
11. Repeat steps 9 –11 for any other amplifiers in
the system.

Troubleshooting:
Problem: The CC-1 is not reading any signal, i.e. the
signal LED won’t illuminate.
Solution:Some amplifiers have the left output on the
Left (+) speaker terminal and the Right output on the
Right (-) terminal. Use left channel, or connect Red
probe to Right (-) and Black to battery ground.
Problem: It just doesn’t seem to be working correctly
Solution: Did you make sure to turn the power off and
then back on if it was previously used and still on? This
is required to reset all of the data the tool gathered
during its last use.
Problem: The signal LED is Red and it won’t do
anything when the READ button is pressed.
Solution: The incoming signal level is too high, reduce
the system volume until the LED turns Green.
Problem: No CD player available
Solution: Tracks can be ripped to MP3, use 192kbps or
higher.
Problem: The CC-1 keeps turning off
Solution: The CC-1 has an auto turn off timer, it will
operate for 8-10 minutes after the “ON” button is
pressed. This is to prevent it from eating your battery
when you forget to turn it off.
Problem: Low battery LED is on…You know what to do

Where do I set my crossover frequency?
This could be debated for days, and it really comes
down to user preference. Here are some guidelines for
the novice as a good place to start. If you hear the full
range speakers “popping” or “bottoming out” when you
play it at high volumes after using value in the chart
below, turn the crossover frequency up until it stops.
