Select the EQ to be adjusted (1-9) by clicking the desired numbered button and deactivating
the corresponding Bypass button. The numbered buttons are a mutually exclusive set (only one
button can be activated at a time). By default all EQs are bypassed.

When an EQ has been selected, it can be adjusted in the graphic box or the text boxes at the
bottom of the screen.
When the bypass is activated for an EQ, the values are saved for future use but do not act on
the signal path. When the bypass is deactivated, changes made to that EQ contribute to the
composite graph that is displayed. The graph shows how the activated EQs combine to affect
the signal path in the current setup.
Right-click the EQ number to bring up a context sensitive menu (see figure 46). Select
to return to default values for the currently selected EQ only, or select
default values for all EQs for the selected speaker channel.
Adjust EQ graphically
When an EQ is selected (see
showing the individual EQ that is being configured with three parameter adjustment handles. A
vertical white line marks the position of the handle (frequency) currently being adjusted.
Click and drag the EQ number (highlighted at the top of the graph) to adjust the horizontal
position of the handle. Click and drag the center handle up or down to adjust the boost or cut
level (in dB).
Click either of the outer handles to adjust the bandwidth, expressed as a Q value (frequency
divided by bandwidth). If either of these outer handles moves, the other outer handle moves in
the opposite direction to maintain a symmetry about the center handle.
NOTE:
When values are altered in the graphics display, the numeric values in the
EQ numerically
section (see the next page) are updated to reflect the changes.
In figure 47 below, the adjustment handles for EQ 3 are shown. The selected EQ is highlighted at
the top of the graph.
