SHARK DSP110 9 The LOW CUT button lets you enter the high pass filter’s cut-off frequency (20 to 150 Hz). When set to OFF the filter is inoperative. The control and “Hz” LEDs light up while you are entering a value. Use the UP/DOWN buttons to edit. Pressing the LOW CUT button for a longer time (please wait, until all five parameter LEDs light up) enables the keypad lock feature which prevents inadvertent editing of parameters and settings. When the keypad lock is enabled, the LOW CUT key’s control LED starts flashing. 10 Use the GATE button to adjust the threshold of the internal Noise Gate (-96 dB through -44 dB). When set to OFF, the Noise Gate is inoperative. The control LED of the GATE button lights up while you are entering a value. Pressing the GATE button for a longer time (please wait, until all five parameter LEDs light up) enables the GATE LEARN function, which automatically sets the Noise Gate threshold by analyzing the program material and adjusting the value accordingly (value detected plus 2 dB). In GATE LEARN mode, the GATE key’s control LED starts flashing. As long as the LED flashes, the detected value is read on the display, when the LED stops flashing, the value is raised by +2 dB. 11 The COMPRESSOR button gives you access to two parameters that let you adapt the DSP110’s Compressor function to the program material. Press the button once to adjust the DENSITY parameter, which controls the compression density from 0 (no processing) to 100 (maximum compression). Press the COMPRESSOR button a second time to adjust the SPEED parameter which controls the Compressor’s attack and release times from 10 to 1000 msec. The “msec” LED lights up as soon as you select the SPEED parameter. 12 The FILTER key allows you to set the feedback detection sensitivity within a range from 1 (no sensitivity) through 100 (full sensitivity). The default value is 50. The control LED lights up during data entry. Briefly press the FILTER key a second time to edit the maximum attenuation of the FB-D filter (from -3 dB through -48 dB in steps of 3). Pressing the FILTER key longer (please wait, until all five parameter LEDs light up) activates the FILTER LEARN function, which automatically searches for feedback frequencies and assigns free filters to the frequencies found. Now you can enter the number of filters (standard: 9) to be used for permanent feedback suppression. Although the remaining filters are also used to eliminate feedback frequencies, they are released once new feedback occurs. Pressing the FILTER key once again activates the FILTER LEARN function. 8 1. INTRODUCTION
