25.3.2 Equalizer
A click on EQ opens the
Equalizer
panel. It is available in all input and output channels, and
affects all routings of the respective channel (pre fader). The panel includes a low cut and a 3-
band parametric equalizer which can be activated separately.
Lo Cut.
Activated by the button Lo Cut. The slope of the high-pass filter is adjustable between
6, 12, 18 and 24 dB per octave. The cut-off point (-3 dB) is adjustable between 20 Hz and 500
Hz.
EQ.
Activated by the EQ button.
Type.
Band 1 and 3 can operate in peak (bell) or shelf
(shelving) mode. The middle band is fixed to peak mode.
Band 3 can also operate as
Hi Cut
(low pass filter),
especially useful for LFE and subwoofer purposes.
Gain.
All three bands can change their amplification
b20 dB to -20 dB.
Freq.
The center frequency of the filters is adjustable
between 20 Hz and 20 kHz. While in peak mode the center
frequency is adjusted, in shelf mode the cut-off point (-3 dB)
will be changed.
Q.
The Quality factor of the filter is adjustable from 0.7
(wide) to 5.0 (narrow).
The frequency graphics give a precise overview of the filter results. Overlapping filters influence
each other. This can be used to achieve more than 20 dB amplitude, or to generate difficult
frequency response optimizations.
Note: TotalMix has internal headroom of 24 dB. Extreme boosts with overlapping filters can
therefore cause an internal overload. In any case such an overload is displayed by the Over
LED of the channel’s level meter.
