Response Graph
This curve is a graphical representation of the combined results of the filter handles in the response
plotter.
Note: The curve does not reflect the accumulated affect of multiple processor
blocks in the signal path.
Cut Filters
Cut filters appear as handles at the bottom edge of the response plotter, with dashed vertical lines
extending along their center frequencies. Their default frequency setting is "OUT," and the default type
is 6dB/Butterworth.
Shelf Filters
The high and low cut/shelf filters appear along a horizontal axis in the center of the response plotter.
Their default frequency setting is "OUT," and the default type is 6dB/oct.
Frequency
This indicates the frequency of the selected filter point. You can change the
value by clicking on the spin buttons, using keyboard controls, or by entering a
specific value. The frequency range is from 25Hz to 20kHz, with "OUT" as the default setting.
Type
This indicates the slope type for the selected filter. The values
available in the pull-down menu vary for cut and shelf filters, as listed
below.
Shelf Cut
6 dB/Octave*
12 dB/Octave
6 dB/Butterworth*

18 dB/Butterworth
24 dB/Butterworth

Gain
This indicates the current gain setting of the selected shelf filter. The range of
available gain values is between –18dB and +18dB in 0.5dB increments, with a
default setting of 0dB. You can change the value using the conventions described in the Faders
section on page 31. When you are working with a cut filter this control is disabled and displays the
word “CUT.”
Clear
Click this button to return filter settings to their defaults. It opens the Clear Options dialog
(figure 48 on page 68), which provides you with the option to clear all filter settings, or to
clear only selected filter settings.
Bypass
Click to pass signal through without the effect of the processor. When bypass is active, the button
appears lighted in red. The default setting is inactive.
