Turns the Equalizer On and Off for the Selected Channel or Bus.
This button engages or disengages the equalizer for
the selected channel or output bus. It will illuminate to
indicate that the equalizer has been enabled.

Activates Control for the Low Band EQ for the Selected Channel or Bus.
This button activates control of the equalizer's Low band for the selected
channel or bus. The button will illuminate to indicate control is active.

Sets the Center Frequency for the Low EQ Band.
The center frequency is the middle of the passband (the mean) between
the lower and upper cutoff frequencies that define the limits of the band.
You can adjust the center frequency from 36 to 465 Hz.
Sets the Gain Attenuation or Boost of the Center Frequency.
This control sets the gain cut or boost at the center
frequency for the Low band. The level of the center
frequency can be set between -15 and +15 dB.
Turns On the Low Shelving EQ for the Selected Input or Ouput Bus.
When the Shelf button is not engaged, the Low band is semi-
parametric. Enabling the Shelf button turns the Low band into
a low shelving EQ that alters, by a fixed amount, a band of low
frequencies at and below a user-selected shelving frequency.
A low shelving EQ is like a bass-control knob on a stereo. In this mode,
the Center Frequency control selects the shelving frequency.

This button activates the controls for the equalizer's
Mid band for the selected input or output. The button

The Mid EQ band is available for all input and output buses.
Sets the Center Frequency of the Mid EQ.
The center frequency is the middle of the passband (the mean) between
the lower and upper cutoff frequencies that define the limits of the band.
You can adjust the center frequency from 380 Hz to 5 kHz.
