The EQ filter has a calibrated curve that improves
the projection of sound. The examples below will
be of help to understand the EQ control function.
Keeping as a reference the above illustrated basic
example
A
:
Turning the EQ control fully
anticlockwise produces a
linear response with
consequent optimization of
speech intelligibility.
example
B
:
This setting is suitable for
general sound reinforcement
applications, multimedia,
karaoke etc..
example
C
:
Turning the EQ control clockwise
boosts the extremes of the
