Channel EQ Parameters
On the left side of the Channel EQ window is the Gain control and parameters for the
Analyzer, while the central area of the window includes the graphic display and
parameters for shaping each EQ band.
 Master Gain slider and field: Sets the output level of the signal. After boosting or
cutting individual frequency bands, you can use the Master Gain fader to adjust the
output level.
 Analyzer button: Turns the Analyzer on or off.
 Pre/Post EQ button: When Analyzer mode is active, sets whether the Analyzer shows
the frequency curve before or after EQ is applied.
 Resolution pop-up menu: Choose the sample resolution for the Analyzer from the menu.
The choices are: low (1024 points), medium (2048 points), and high (4096 points).
Graphic Display Section
 Band On/Off buttons: Located above the graphic display. Click a button to turn the
corresponding band on or off. Each button has a icon showing the type of EQ it uses:
 Band 1 is a highpass filter.
 Band 2 is a low shelving filter.
 Bands 3 through 6 are parametric bell filters.
 Band 7 is a high shelving filter.
 Band 8 is a lowpass filter.
 Graphic display: Shows the current curve of each EQ band. You can adjust the
frequency of each band by dragging left or right in the section of the display for that
band, and adjust the gain of each band (except bands 1 and 8) by dragging up or
down in the band’s section. The display reflects your changes immediately.
Parameter Section
Below the graphic display area are controls that you can use to show the settings for
each band and adjust each band’s settings.
 Frequency fields: Adjust the frequency of each band.
 Gain/Slope fields: Adjust the amount of gain for each band. For bands 1 and 8, this
changes the slope of the filter.
 Q fields: Adjust the Q or resonance for each band (the range of frequencies around
the center frequency that are affected).
The Q parameter of band 1 and band 8 has no effect when the slope is set to 6 dB/
Oct. When the Q parameter of bands 3 through 6 is set to an extremely high value
(such as 100), these filters only affect a very narrow frequency band, and can be used
as notch filters.
