Channel EQ Graphic Display Section
• Band On/Off buttons: Click to turn the corresponding band on or off. Each button icon
indicates the filter type:
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.
• Drag horizontally in the section of the display that encompasses each band to adjust
the frequency of the band.
• Drag vertically in the section of the display that encompasses each band to adjust
the gain of each band (except bands 1 and 8). The display reflects your changes
immediately.
• Drag the pivot point in each band to adjust the Q factor. Q is shown beside the cursor
when it is moved over a pivot point.
Channel EQ Parameter Section
• Frequency fields: Adjust the frequency of each band.
• Gain/Slope fields: Set the amount of gain for each band. For bands 1 and 8, this changes
the slope of the filter.
• Q fields: Adjust the Q factor or resonance for each band—the range of frequencies
around the center frequency that are affected.
Note: 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 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.
• Link button: Activates Gain-Q coupling, which automatically adjusts the Q (bandwidth)
when you raise or lower the gain on any EQ band, to preserve the perceived bandwidth
of the bell curve.
• Analyzer Mode buttons (Extended Parameters area): Choose Peak or RMS.
• Analyzer Decay slider and field (Extended Parameters area): Adjust the decay rate (in dB
per second) of the Analyzer curve (peak decay in Peak mode or an averaged decay in
RMS mode).
• Gain-Q Couple Strength pop-up menu (Extended Parameters area): Choose the amount
of Gain-Q coupling.
• Choose “strong” to preserve most of the perceived bandwidth.
• Choose “light” or “medium” to allow some change as you raise or lower the gain.
