7. De-equalization.
De-equalization of the OEM source, operation not required and
not necessary if using low level inputs (Pre out).
During the high level input configuration procedure, this function
can be used to maximize use of the OEM head units, even if
they were equalized to adapt best to the acoustics of the car
they are installed in. The de-equalization procedure performs
an analysis of the electrical frequency response coming from
the various channels on the OEM head unit and automatically
applies an equalization opposite to the original one, generating
a linear signal that is much more suitable to driving high quality
audio systems. Regardless of the input channels used,
the de-equalization will be performed by functional groups.
The software uses a progress bar and specific messages to
show how the procedure is being executed.
At the end of the procedure, the window will show the
equalization curves for the head unit.
Press
BACK
to return to the previous step.
Press
NEXT
to continue with the configuration.
Press
CANCEL
to exit the program.
E.g.:
Even if using Front Left Full and Front Right Full as inputs, the software will also perform the de-equalization
on the Rear, Center and Subwoofer since the processor must use the signals identified as Front to also control
any possible Rear, Center and Subwoofer outputs.
If you decide to perform this procedure, follow the instructions below:
-
Insert the supplied Setup CD if the source used is an audio CD player;
-
Play track 2 (press Play);
-
Set all of the tone controls to zero (0).
-
Set the balance and fader to the center (0).
-
Don’t change the adjusted volume previously set through the automatic input level calibration;
Press
BACK
to return to the previous step.
Press
GO
to continue with the configuration.
Press
SKIP
to abandon the procedure.
Press
CANCEL
to exit the program.
