Set-up
Setup (Filter Learn)
For best results‚ complete the Filter Learn in a relatively quiet room. This allows the Feedback Ferret D to
find primary acoustic feedback frequencies. Every room and setup has problem frequencies. This makes
each room different and creates different feedback problems. It is important to understand that while in
Filter Learn mode‚ the Feedback Ferret D does not distinguish between feedback and music. If you play
music through the system while in Filter Learn mode‚ theFeedback Ferret D will try to eliminate it.
Step One
These instructions assume you have connected the Feedback Ferret D from the mixer outputs and not
from a single channel insert. Make sure that the Normal/Filter Learn LED is lit (this engages Filter Learn
Mode) and that your microphone levels are set. Slowly bring up the master level. You should see the fil-
ters seek and lock as feedback starts to occur. The Feedback Ferret D will begin with filter 1 and progress
from left to right automatically. You will notice that each filter will first blink and then light solidly as
each frequency is locked down. This is accomplished with the minimum amount of
attenuation.
Step Two
Continue bringing the master level up until you've reached the required volume level. As you start to
hear feedback‚ stop adjusting the levels momentarily to allow the Feedback Ferret D to complete its
filter adjustment. Normally‚ you should hear the onset of feedback before the Feedback Ferret D takes
control. In most applications‚ this should give you plenty of gain and still leave additional filters open
for later use. If all or most of the filter LEDs are lit up‚ bring the master level back down‚ reset the filters
and start over. But this time‚ push the Wide button on the front panel. This allows each filter to work on
a wider range of frequencies, thereby freeing up additional filters for other uses. A typical room should
only set one to six filters during this soundcheck setup. (Note: If all or most of the filter LEDs light up,
this probably indicates a bad room‚ bad system setup or too much volume!)
Step Three
Finally‚ switch the unit to Normal (Filter Learn Off ) mode. This automatically engages the Panic button.
Your system should now be performance-ready! At this point‚ it is advisable to engage the Front Panel
Disable Switch in order to minimize accidental changes. Once you are content with your settings‚ press
and hold one of the preset buttons (1–4) to save your filter settings.
Note: The Feedback Ferret D is not a replacement for a good soundperson. Good sound system
performance starts with good microphone and speaker placement.
