Handles
Each band handle is positioned along the line curve displayed in the graph. You can click and
drag each handle to choose the frequency you wish to adjust for that band and the gain you
want to set. When moving a handle with your mouse, both the frequency and gain settings are
affected simultaneously, which gives you a fast way to make quick adjustments to each band
across the entire range of frequencies.
NOTE To make changes using a handle, ensure the band is enabled. Simply click on
the band you want to adjust. The band label will illuminate blue when enabled.
As you drag a handle left or right, you will notice the frequency and decibels update in the band
settings. This will also be reflected by the frequency range preset buttons for low, medium low,
medium high and high.
Frequency Knobs
Alternatively, you can use the frequency knobs for each band to select a specific frequency
to adjust.
Range Presets
The frequency range for each band is defined by the range preset buttons. For example, low is
labeled 'L' and covers the frequency range from 30 to 395 Hz.
As a quick example of how the range presets define the frequency range, select a notch filter
from the band filter dropdown list and then click on each range preset. You will see the filter
effect move to a position along the graph curve that corresponds to the range preset you
choose. This lets you quickly define a specific range of frequencies you want the filter to affect.
Below is a table showing the range of frequencies for each range preset setting.

Gain Knobs
Click and drag the gain knob left or right to decrease or increase the volume level for the
selected frequency.
Q Factor
The Q factor control is available when the bell filter is applied to bands 2, 3, 4 and 5. This sets
the range of frequencies the filter will affect. For example, setting the minimum will allow the
filter to affect a wide range of surrounding frequencies and the maximum setting will narrow
the effect down to a tiny point. This is important if you have sound qualities in surrounding
frequencies that you want to either include or exclude from the change you are making.
As you adjust the Q factor, watch the shape of the effect on the line curve change from a broad,
rounded edge to a sharp point. This is a visual representation showing how the regions of
frequencies surrounding the target frequency are affected.
