EQ processing is available for all sources. The EQ section includes a 3-band parametric EQ plus 2-band filters.

Parametric EQ

There are three bands of parametric EQ: Low, Mid and High. Each band can operate across the full frequency range and is set independently. The following parameters can be adjusted:

  • Gain - from -15dB to +15dB.
  • Frequency - from 20Hz to 18kHz.
  • Q - from 0.7 to 15.

Filters / Shelving EQ

For the 2-band filters, each band can operate either as a fixed slope filter (High Pass/Low Pass) or as a shelving EQ (Low Shelf/High Shelf).

In High Pass/Low Pass mode, the filter slope is fixed at 12dB per octave. The cut-off frequency can be adjusted from 20Hz to 18kHz.

In Low Shelf/High Shelf mode, the slope of the shelving EQ is defined by the gain value. Thus, there are two parameters that can be adjusted: gain (from -15dB to +15dB) and frequency (from 20Hz to 18kHz).

Operation

To access the parameters, press an Access key (on the fader strip) followed by EQ (on the Central Function Keys and/or GUI).

Then adjust the parameters from either the surface or GUI.

On the surface...

There are two pages of parameters: one for the parametric EQ and one for the filters.

  • Press down on the left (master) rotary control to toggle between the pages.
  • The EQ soft key acts as the master on/off for the complete section: 3-band parametric EQ + 2-band filters. This key appears in the same position on both pages.
  • For the Gain/Freq controls: turn to adjust Gain; press down and turn to adjust Frequency.
  • To adjust the Q, press the + or – soft keys to increase or decrease the Q value.
  • On the second page, use the soft keys to set the EQ type for the filter bands:
    • Lower band - select either HPF (High Pass Filter) or LoSh (Low Shelf).
    • Higher band - select either LPF (Low Pass Filter) or HiSh (High Shelf).

On the GUI...

The parameters for all five bands are shown simultaneously, and there is a visualization that shows the overall frequency response.

'Source Parameter' dialog box (EQ)

  • The EQ button acts as the master on/off for the complete section: 3-band parametric EQ + 2-band filters.
  • The EQ curve provides an easy way to check if the processing is turned on or off:
    • Curve (filled) = EQ on.
    • Curve (not filled)  = EQ off.
  • To adjust each of the five bands, you can either touch and drag a numbered point on the EQ curve, or touch and drag the values inside the parameter boxes:
    • Band 1 = Low Cut (High Pass) Filter or Low Shelf.
    • Band 2 = Low band Parametric EQ.
    • Band 3 = Mid band Parametric EQ.
    • Band 4 = High band Parametric EQ.
    • Band 5 = High Cut (Low Pass) Filter or High Shelf.
  • For the two filter bands, use the Response parameter to set the EQ type.
  • The meters show the levels at the input and output of the EQ section.
