SHARK DSP110
+ When both FILTER LED and display stop flashing, the FILTER LEARN function
has been completed. Press the FILTER key to cancel the function. After a
short delay, the unit returns to the FILTER menu.
The FILTER LEARN function generates short feedback-causing signals that
are sent back to the DSP110s input, where feedbacks are detected and
suppressed. The FILTER LEARN function is an useful tool for live concerts that
prevents filters from being released prematurely. Fixed filters can only be
reconfigured as free, searching filters by means of a RESET. In normal mode,
which is activated after power-up, set filters are automatically released one after
the other, when free filters are needed to search and destroy feedback
frequencies.
+ To ensure that the FILTER LEARN function works properly, the short
feedback-causing signals are output with a level of -18 dB below digital
maximum. However, the feedback caused during the FILTER LEARN
procedure will be limited by the compressor to -30 dB below digital
maximum. Please note that considerable volume levels can still occur,
which is why you should use the FILTER LEARN function only before the
concert/event begins.

Enable the ACTIVE button to set inoperative filters to automatic search mode.
When this button is up (control LED is off), those filters are inoperative which
have not yet found a feedback frequency. Pressing the ACTIVE button for a
longer time (please wait, until all five parameter LEDs light up) enables the
RESET function. All filters will be reset, i.e. set to automatic search mode.
