Figure 2.22: EQ Frequency Response
EQ frequency response
See Figure 2.22 . This panel displays the frequency response of the active exciter’s EQ filter.
The panel displays the gain of the filter with respect to the magnitude and frequency of the
modulating signal. A dashed line is displayed at the 0 dB level.
This tool is useful for installations featuring filter coefficients loaded to compensate for a
channel combiner response.
Touch on the panel to display a cursor in the approximate area. The cursor position
(magnitude and amplitude) is noted in the upper, right-hand corner of the panel. Touch in
other areas of this instrument panel to provide a coarse adjustment of the cursor position.
Use the left and right buttons as fine adjustments. Use the maximize or minimize buttons as
required.
