User manual SABINE FBX-900

[. . . ] More detailed instructions are on page 7 inside this operating guide. 1. Place the FBX between the output of your mixer and the input of your power amp. With the master volume down, put the FBX-900 in active mode (red BYPASS LED off), then slowly raise the mixer master volume to the point of feedback. Keep raising the master volume until all of your fixed filters and one dynamic filter are set, then lower the volume slightly. [. . . ] The LOCK FIXED LED will light to indicate that the FBX is in LOCK FIXED mode. The fixed filters stay locked until you press the LOCK FIXED button again. Selecting filter width If you're using the FBX for a music application, the standard 1/ 10-octave Constant Q filter is usually preferable. However, in spoken word applications, such as lectures or teleconferencing, we recommend using the wider 1/5-octave filter for more robust feedback control. You may enable the 1/5-octave filters by pressing the "FIFTH OCTAVE" button, and the built-in LED will light. Only filters set after pressing the button in will be 1/ 5-octave. Press the button again to set subsequent filters to standard 1/10-octave filters. You can mix filter widths in the same channel (see "IMPORTANT TIP" below). setup feature cuts the time for FBX filter initialization to just a few seconds, and it reduces the volume level of the feedback during setup. The 2020 is set in TURBO mode at the factory and automatically engages every time you press RESET (resetting filters). The 2020 automatically returns to normal program mode when the first dynamic filter is set or when you press the front panel LOCK FIXED button. ALL FILTER LEDS WILL CYCLE TO INDICATE THE FBX IS ABOUT TO EXIT TURBO MODE. WARNING: TURBO Mode will cause distortion in your audio program -- it is for setup only. You cannot mix dry signal with effects signal and still control feedback. Be sure that the program is interrupted when the input is disconnected from the back of the unit. Can I mix balanced and unbalanced inputs and outputs?An unbalanced input and balanced output are compatible. However, a balanced input and unbalanced output may result in a 6 dB loss of dynamic range, and the bypass function may not operate correctly. Why does one of the FILTER ACTIVITY LEDs blink?The last filter to be automatically updated blinks. During normal operation, the blinking will move from filter to filter as they are reset. This gives the user a visual confirmation that the unit is responding to new feedback and is functioning properly. Sometimes during the initial setup, the first filter LED will blink before any feedback has been introduced into the system. The FBX will set a filter if the system has a hum.
