GEQ front panel features
The front panel of the GEQ, as displayed on the GUI, represents the Klark Teknik DN370
Graphic Equaliser. It includes a graphic EQ (faders) section and a filters section.
Thirty one faders provide fine adjustment of each frequency band. The 31 frequency
bands are spaced 1/3 octave apart on the standard ISO 266 frequency centres. All the
functions of the GEQ can be bypassed via an EQ switch, such that the output will be the
same as the input.
The GEQ has one high pass filter, one low pass filter and two variable frequency notch
filters. Each filter is adjusted via a control knob on the GUI screen. To audition the
effect of the filters, use either the EQ switch (which will also bypass the GEQ) or the
individual filter switch.
