Sets the Gain Attenuation or Boost of the Center Frequency
of the Mid Band.
This control sets the Gain cut or boost at the center
frequency of the Mid band. The level of the center
frequency can be set between -15 and +15 dB.
Enables a Narrow Bandwidth for the Mid Band EQ on the Selected
Input or Bus.
Q is the ratio of the EQ band's center frequency to its bandwidth.
With a constant center frequency, higher Q values indicate a
narrower bandwidth, so Q is often equated with bandwidth.
By default, the Q is set to a value of 0.55. When the Hi Q
button is engaged, the Q setting will be increased to 2.0, thus
narrowing the bandwidth to provide more precise control.
Activates Control for the High EQ for the Selected Input or Bus.
This button activates control of the High band for the selected channel
or bus. The button will illuminate to indicate control is active.
The High EQ band is available for all input and output buses.
Sets the Center Frequency of the High 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 1.4 to 18 kHz.
Sets the Gain Attenuation or Boost at the Center Frequency of the High
EQ Band.
This control sets the gain cut or boost at the center
frequency of the High EQ band. The level of the center
frequency can be set between -15 and +15 dB.
Turns on the High Shelving EQ for the Selected Input or Bus.
When the Shelf button is not engaged, the High band is a semi-
parametric EQ. Enabling the Shelf button turns the High band into
a high shelving EQ that alters, by a fixed amount, a band of high
frequencies at and above a user-selected shelving frequency.
A high shelving EQ is like a treble-control knob on a stereo. In this
mode, the Center Frequency control selects the shelving frequency.
