Response Plotter
This area of the window graphically displays the pass band filters and crossover points, which you can
manipulate by clicking and dragging with the mouse.
Pass Bands
Each band has a corner handle on either side that you can drag left and right to
individually adjust the upper and lower corner frequencies. There is also a gain handle
in the center of each band that you can drag up and down to adjust the output level of
the pass band. When you select a handle, it fills with a colored ball to indicate that it is the active control.
The upper and lower filter slopes are set with the pass band controls in the lower section of the window.
Crossover Handle
This handle indicates the frequency of the crossover point between two pass
bands. You can drag it left and right to simultaneously adjust the corner
frequencies of the intersecting filter slopes. When you select a crossover
handle, it turns green to indicate that it is the active control, and the
corresponding corner handles fill to indicate they are selected. The corner
handles maintain their positions relative to each other as you slide the
crossover handle.
Output Channel Labels
These labels at the head of the columns of pass band controls are color-coded to match the
corresponding band pass curves in the response plotter. They indicate to which output channel each
pass band is routed.
Set and Show Gains/Normalize Plot
Toggle between these two buttons to
alternately display the pass bands at
their actual gain levels, and display them
normalized. The default setting is [Set
and Show Gains on Plot].
When the gain levels of pass bands are
significantly different, the crossover point
appears offset from its actual location, as
illustrated in figure 36 on the right. Use the
normalize plot display mode when you
need to see the precise location of the
crossover point, as illustrated in figure 37,
below right.
• Click the [Set and Show Gains on
Plot] button to display and adjust pass
band gain levels. With this setting,
filter levels are reflected in the
response plotter and the gain handles
are visible on the pass bands.
• Click the [Normalize Plot] button to
display the pass bands at unity gain in
the response plotter. Actual gain
settings are not affected by this setting.
