DIGITAL PROCESSING ARENA
so that an adjustment made to the L output will not make that same adjustment to the R output. This
would be handy should the L & R outputs of your system be set up in an asymmetrical fashion (e.g., one
speaker stack is set up near a corner and the other centered along a wall). This would probably require
different EQ for each speaker to be balanced. It is also appropriate where one output drives a main
speaker cluster and the other output drives a remote speaker (or a different speaker configuration).
Subwoofer: This again combines the L & R busses and installs an electronic crossover in the output sec-
tion. This crossover may be adjusted so that one output (Left main) drives the low or sub output and the
other (Right main) drives the main or HF output. The Delays and the Limiters may be adjusted indepen-
dently for the two different outputs. The crossover employs a 4th order set of filters (24 dB/oct) and
Butterworth or Linkwitz-Riley filters may be selected. CD horn compensation is available for Constant
Directivity horns.
PROCESSOR MODULES
Feedback Ferret:
Press the "Output Processing" button.
Turn the left knob to highlight the first block (the Feedback Ferret block), and select it by pressing the knob.
Press "Type" and use the left knob to select "Feedback Ferret." Press it again to choose between "Dynam-
ic" and "Static" mode.
Dynamic Mode: Dynamic mode, when on, will detect feedback and eliminate it automatically. Once a feed-
back elimination filter has been activated, it will be released after a certain amount of time to allow other
feedback frequencies to be detected. If the feedback is severe enough, the feedback elimination filter for
that frequency will lock in place, not allowing it to be released. The only way to release a locked filter is to
select "Clear" on the "Edit" page, which will clear all of the current filters, locked or not.
Static Mode: Unlike Dynamic mode, Static mode involves a setup process and is the recommended mode
for more robust feedback elimination. Once Static mode has been selected, select "Detect" to begin de-
tecting feedback. In order for feedback to be eliminated, feedback must be present, so it is recommended
to increase the gain of the mixer in order to achieve feedback. Once feedback is sufficiently present, a
filter should be activated to eliminate the feedback and the number of available filters should decrement
accordingly. Once you are satisfied with the feedback elimination filters, select "Back" to lock these filters
in place. Once this is accomplished, feedback will no longer be detected and the filters in place will not
release until "Detect" is selected again. A group of filters can be saved in the library by name and recalled
when you play the venue again, although it would be best to repeat the setup process again as things will
always change a little.
PEQ: Highlight the second box from the left and select "type." You can press the "Lib" button to select a
saved setting, or you can edit the existing setting by navigating around the screen.
The left encoder knob selects the band (1-5) to edit. Once you have selected that band, pressing the left
knob will allow you to adjust the center frequency of the filter selected. The right encoder knob toggles
between "bandwidth" and "gain." Bandwidths between 0.3 octave and 2.0 octaves may be selected as
well as gain levels from -12 dB to +12dB. When you have made your adjustments, you may save them to
the Library by pressing the "Lib" button and selecting "Save current settings." You can title your settings
by selecting the name button and assigning a name or you can save it over an existing setting. Select a
name or a "free" setting and press "save."
GEQ: Highlight the second box from the left and select "type." Scroll to "Graphic EQ" and select by
pressing the left encoder knob.
The left encoder knob controls the selection of the frequency to be modified and the right encoder knob
selects the gain, +/- 12 dB. The left encoder knob can also select the left most slider for gain adjustment
of the GEQ as a whole. Selecting the "Lib" button will allow you to save or recall your settings.
