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. 13 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. 1.
