about one foot from the center console.
Click the button to proceed when you are ready.
You will hear the frequency sweep (“whoop-
whoop”) playing at a low volume.
Use the volume slider on the screen to gradually
raise the volume until the input level rises to the
middle of the volume monitor.
AutoEQ will automatically stop playing the signal
after it detects a good level for a few seconds.

This section explains the measurement portion of
AutoEQ.
Microphone movement
Correct microphone movement during sound
measurement is critical to getting a good result from
AutoEQ. Please read this section carefully.
1 Overview
To make a measurement, you will move the
microphone through the space of the cabin while
AutoEQ plays a frequency sweep (“whoop-whoop”
sound).
The key is to move the microphone constantly and
consistently so that all of the space in the cabin is
evenly covered during measurement.
This is important, so we will explain it in detail.
2 Measurement points
One AutoEQ measurement consists of at least 200
measurement points. That is, the frequency sweep
(“whoop-whoop”) will be played 200 times in order
to measure the cabin’s sound.
The exact point in space where the microphone is
when it hears one frequency sweep is a
measurement point. The sound was measured at
that point.
The goal of microphone movement is to space these
measurement points as evenly as possible in the
frontal space of the car cabin.
3 Range of movement
Spaces through which you should move the
microphone include:
• The space above the dashboard.
• The space in front of the driver and passenger, as
low as the front of their shins (going slightly into
the foot wells) and as high as the ceiling.
4 What to avoid
When moving the microphone for a measurement:
• Do not stop moving the microphone at all,
including for individual measurement points.
Constant movement is best.
• Do not go deep into the foot well spaces in the
measurement.
Perform measurement
When you are ready, click the button to begin
measurement.
A countdown will begin on the screen, and then the
measurement process will begin.
For the duration of the measurement, move the
microphone through the cabin of the car as
described in the previous section.
During measurement, the result of each sweep will
be displayed on the screen with a faint curve and
the average will be shown with a strong curve.
Figure 4 - The measurement screen showing a
measurement in progress.
The progress of the entire measurement will be
shown in a progress bar at the bottom of the screen.
The app will confirm when measurement is
completed.
Figure 5 - The measurement screen showing a
measurement that has been completed.
If you see no obvious problems with the
measurement, you can accept it. If not, choose
“remeasure” to retry measurement.
Measurement
21-EN
With measurement complete, you are ready to tune
the sound in the vehicle.
Tuning screen
This section is an introduction to the tuning screen.
It will cover the controls shown on the screen
without discussing procedure.
Figure 6 - The tuning screen with its default options
shown.
1 Side Panel Controls
These are the controls available outside of the main
graph area:
EQ Gain Offset - This setting adjusts the boost and
cut of the EQ. This will be the first step in your tuning
process.
Reset to Default - This button resets everything on
this tuning screen to defaults.
Bypass EQ - This toggle allows you to A/B test the
sound with the EQ on and off.
Level - This slider controls the volume of the music
source.
2 Graph Curves
These are the curves shown in the main graph area.
The display of each one can be toggled on and off.
Target (yellow) - This is the curve which you will
manipulate to tune the system. AutoEQ will match
your system’s sound to this curve.
Measurement (dark teal) - This is the measured
APVD of your car’s system.
EQ (blue) - This is the correction curve AutoEQ will
apply in order to achieve your target curve.
Predicted (gray) - This curve shows what the
predicted result from your target curve will be.
It will vary slightly from the target (yellow) curve, or
may be hidden behind it if AutoEQ is going to hit
your target exactly.
Distortion & Noise (magenta) - This curve shows
the distortion and noise that were present during
your measurement.
Tuning Process
This section covers the standard procedure using
the tuning screen to create your EQ.
1 Check the Distortion & Noise Level
Before proceeding, we must check the Distortion &
Noise curve relative to the Measurement curve. To
make this easier, you may turn off display of all other
curves.
Where the Distortion & Noise curve comes too close
to the Measurement curve, that means there is too
much noise to rely on this measurement in that
frequency range. The Distortion & Noise curve
should be at least 10 dB below the Measurement
curve. If it is 6 dB or closer, that frequency range of
the measurement is unreliable.
Figure 7 - The tuning screen showing an
unacceptable high amount of noise.
It is expected that the Distortion & Noise curve will
approach the Measurement curve in the very low
frequency ranges. This will be in the frequency
range where ambient noise overpowers the system’s
capabilities. This is not a problem.
Figure 8 - The tuning screen showing a good noise
level, well below the measurement curve.
Tuning
22-EN
2 Adjust the EQ Gain Offset
This setting will define the amount of boost and cut
AutoEQ will use.
When adjusting EQ Gain Offset, it is best to turn on
the display of only the Measurement and EQ curves
in the graph area. This way, you can clearly see the
boost/cut areas.
•Boosted areas are the frequency ranges where
the EQ curve is above the Measurement curve.
•Cut areas are the frequency ranges where the EQ
curve is below the Measurement curve.
Use the slider to raise or lower the EQ Gain Offset
until there is an equal amount of boost and cut
across the graph.
Bad offset sample Figure 9, Figure 10.
Figure 9 - The tuning screen showing an EQ Gain
Offset with too much cut. The EQ curve is entirely
below the Measurement curve.
Figure 10 - The tuning screen showing an EQ Gain
Offset with too much boost. The EQ curve is entirely
above the Measurement curve.
Good offset sample Figure 11.
Figure 11 - The tuning screen showing an EQ Gain
Offset that is good. It is balanced between cut and
boost.
3 Play reference audio
If you want to play reference audio while tuning, you
can start now. You can play audio from a music
player app on your PC, or you can send audio into
the amp from a completely separate input. Both will
work for real-time tuning.
4 Adjust the Target Curve
Enable the display of the Target curve. (Displaying
other curves is optional.) This is the yellow curve
with control points which you can set to define your
desired outcome. Each control point is represented
as a node (white dot) on the curve.
Moving the control points - To move a control
point, simply drag it to the desired location. You can
move it side to side or up and down.
Adding a control point - To add a control point,
double-tap on the Target curve where you want to
create the new point. Then, drag that point to adjust
its position.
Deleting a control point - To delete a control point,
double-top on it. You will have an option to delete
that control point, or to cancel deletion.
As you modify the target curve, AutoEQ will update
the EQ curve and send it to the amp so you can hear
your result. There is a delay of a few seconds from
when you make an adjustment to when you hear it
from the system.
5 Storing the EQ Curve
When you are done adjusting your target curve, you
can click the Store button to finalize the EQ curve on
the amp.
The EQ data is now saved on the amp.
23-EN
This section covers how to manage saved amps in
AutoEQ and how to reconnect to an amp you have
already worked on.
Reconnect to an amp
To reconnect to an amp you have worked on
previously, you must have that amp connected to
your PC via USB. The amp will appear in the Recently
connected list. To work on this amp, simply click on
its name.
Rename an amp
It is strongly recommended to give an amp a name
that is easy to remember. To rename an amp from
the Recently connected amps list, click on the three-
dot menu icon on the right side of its name. Choose
“Edit.”
You can now rename the amp by changing the
name in the text field. The original name of the amp
will always be saved and shown in the amp info.
Remove an amp
To remove an amp from the Recently connected list,
tap on the three-dot menu icon on the right side of
its name. Choose “Edit.”
Click the button at the bottom of the menu to
remove the amp from your app.
