The DELAY button allows you to adjust the Delay Line time. Press the button 

several times to either choose msec, feet or meter. The last unit selected will 

be stored and recalled next time you use the DELAY function. The control LED 

lights up while you are making your entries. The setting range is from 0 to 

2,500.0 msec, 0 to 2,818.2 feet, and 0 to 859.00 meters. When you are using 

high values, the 4-digit display reads the last figure only when you start 

editing with the UP/DOWN buttons. Example: for a value of 1,500.0 msec, 

the display reads “1500” when you press the DELAY button, and “500.0” 

when you start editing. In this way, you can use extremely small steps when 

editing parameters.

(7) 

The DOWN button lowers the parameter values shown in the display  

(4)

.

(8) 

The UP button raises these parameter values.

(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 FBQ100’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.

The FILTER LEARN function generates short feedback-causing signals that 

are sent back to the FBQ100’s 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.

(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.

This is the SHARK’s balanced XLR INPUT.

(16) 

The MIC GAIN control adjust the input signal gain, when the INPUT LEVEL 

switch  

(21)

  has been pressed (position: MIC). To adjust microphone levels 

you can use the CLIP LEVEL indicator, by setting the CLIP LEVEL control to 

mid-travel position. Please make sure that the CLIP LED will not light up.

(17) 

Use the POWER SUPPLY CONNECTOR to hook up the SHARK’s external 

power supply.

(18) 

This is the SHARK’s balanced JACK OUTPUT, which carries the same signal as 

the XLR output.

(19) 

The OUTPUT LEVEL switch controls the reference level provided by the 

outputs of the FBQ100. Possible values are: +4 dBu or microphone level.

(20) 

This is the SHARK’s balanced JACK INPUT, which is wired in parallel to the 

XLR input.
