107MainStage Effects
• Drag the control point to adjust the center frequency only.
Note: Horizontally dragging the control point in band 1 and band 8 adjusts both the
frequency and Q.
• Hold down Option-Command to adjust the Q and center frequency simultaneously. A
“Q” icon is shown at the pointer position.
MainStage Channel EQparameters
The central area of the Channel EQ window includes the graphic display and parameters
for shaping each EQband. The master Gain slider is shown at the right. The Analyzer and
Q-Couple controls are shown at the lower left.
Channel EQ parameters
• Band1 On/Off button: Switch on a low cut filter that allows high frequencies to pass and
reduces the level of low frequencies near the cutoff (set) frequency.
• Band 1 background or control point: Drag the red control point to change the
frequency and Q values. Drag the red shaded area horizontally to change the
frequency value.
• Band 1 vertical/horizontal line: Drag vertically to change the slope.
Note: The Qparameter of band1 and band8 has no effect when the slope is set to
6decibels per octave. When the Qparameter is set to an extremely high value, such
as 100, these filters affect only a very narrow frequency band and can be used as
notch filters.
• Band2 On/Off button: Switch on a low shelving filter that adjusts the level of low
frequencies and has a minimal impact on frequencies above the cutoff (set) frequency.
• Band 2 background or control point: Drag the orange shaded area, curve, or control
point to change the frequency and gain values. Click the control point to select the
band.
• Band 2 horizontal line: Drag vertically to change the gain value.
• Band 2 vertical line: Drag horizontally to change the Q value.
• Band 2 vertical/horizontal lines: Drag to change the gain and Q values.
