Figure 4-13 PEQ Edit Portal 2
Portal 3 (and Portal 4 for Mesa filters only) displays the bandwidth, frequency, and
gain of the selected filter. The outer ring provides a visual reference of the frequency
range that is being affected by this filter, with bottom left being the lowest frequency
and bottom right the highest frequency.
Figure 4-14 PEQ Edit Portals 3 and 4
Portal 4 is used for Mesa filters only, to show the details for the second related filter
component. For Mesa filters the visual scale and gain values are identical on both
Portals; the bandwidth and frequency are independently adjustable. An example of
the PEQ Edit menu for a Mesa filter is shown in Figure 4-15.
