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.

Offset that is good. It is balanced between cut and
boost.

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.

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.

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.
