Proceed as follows:
- Tick the “Enable phase correction” box if you want to enable the
loudspeakers phase automatic correction.
- Choose the type of equalization curve to apply to the system by selecting a pre-set curve
from the
“Target Curve”
menu; or, create a custom curve clicking on the
“Target Curve”
Three pre-set Target Curves are selectable:
Flat Curve, Acoustic, Rhythm
(default).
Flat Curve:
it doesn’t apply any equalization to the system, ensuring linear response
that can be measured with the RTA instrument.
Acoustic:
it applies an equalization optimized to listen to instrumental music.
Rhythm:
it applies an equalization optimized to listen to rhythmic music.
- Select on the
“Algorithm
” menu the type of algorithm to apply to the audio
system frequency response (suggested:
Medium
).
Remark:
Three algorithms are selectable: Soft, Medium, Hard. The algorithm processes the data that the bit Tune
measures making the response curve similar to the Target Curve. This approximation can be either less
strict (Soft) or more precise (Hard). The choice of the algorithm type depends on many factors, such the
passenger compartment’s structure, the audio system setup, etc.
Your experience will suggest the best type of algorithm, to customize the type of music. The suggested
choice constituting the best compromise is the
Medium
algorithm.
- Select
Process Data
to process the entered information.

WARNING:
do not confuse the “Enable
phase correction” with the
“Polarity Check” instrument
.
The “Enable phase correction” suggests the possibility to improve the
acoustic response by inverting some louspeakers’ phase.
The acoustic improvement offered by the phase inversion depends on
multiple, also subjective, factors . Therefore its effectiveness needs to be
in any case verified from an acoustics point of view (see point 9) comparing the two settings.
6.
At the end of the measurement you will see:
- A window asking for the presence of hidden speakers in the listening system:
- Choose
Yes
, to select the real distance of the hidden speakers.
- Choose
NO
, to continue with the calibration procedure (point 15).
Note:
Hidden speaker. It is a speaker positioned behind a barrier which is almost
closed with respect to the
HSM
microphone. The barrier may prevent the
microphone from properly calculating the distance through the time delay.
Generally, the hidden speaker is a Subwoofer located in the luggage
compartment of the vehicle.
7.
Click on hidden speakers respect to the listening point and manually
enter the correct distance.
WARNING:
If your system has a Subwoofer, enter the distance in cm or
inch measuring it manually.
- Choose
OK
to continue;
- Choose
CANCEL
to exit the process.
