10 EQUALIZING the SOUND (EQUALIZER)
161
This section allows you to make use of a
(mutually exclusive) graphic or parametric
equalizer, used to regulate the equalization
of the sound.
The section relating to the equalizer
comprising the following controls:
•
[MID MODE]: defines the type of
equalizer:
-
GRAPHIC: graphic equalizer
-
PARAM. (Parametric): parametric
equalizer.
The names and functions of the controls
relating to operation of the equalizer vary
depending on the type of equalizer adopted.
We will now see how they act on the signal:
MID MODE=GRAPHIC
•
[60]: enhances / attenuates the signal in the frequency
region centred on 60 Hz.
•
[200]: enhances / attenuates the signal in the frequency
region centred on 200 Hz.
•
[600]: enhances / attenuates the signal in the frequency
region centred on 600 Hz.
•
[2K]: enhances / attenuates the signal in the frequency
region centred on 2 KHz.
•
[6K]: enhances / attenuates the signal in the frequency region centred on 6 KHz.
For all the sliders, the totally down position corresponds to an attenuation of the signal of -12 dB
at that specific frequency. In the central position there will be no effect on the sound, while with
the slider fully up there will be an enhancement of the signal of +12 dB.
MID MODE=PARAM.
•
[LOW]: regulates the enhancement / attenuation of the
signal with frequencies below 60 Hz.
•
[MID]: sets the region of the medium band frequencies of
the signal to be enhanced / attenuated.
•
[FREQ]
(Frequency)
: regulates the enhancement /
attenuation of the area of frequencies set using the [MID]
trimmer.
