6.1 Basic Equalization

  1. Power on your audio system, ensuring the FBQ3102 is the last device to be turned on and the first to be turned off.
  2. Set all frequency faders to the 0 dB (center) position.
  3. Säädä INPUT GAIN controls so that the input/output level meters show a healthy signal without clipping (red LEDs).
  4. Käytä ALUE switch to select either ±6 dB or ±12 dB adjustment range for the frequency faders. Start with ±6 dB for finer control.
  5. Säädä yksilöllisesti FREQUENCY FADERS to shape your sound. Boost frequencies to emphasize them or cut frequencies to reduce unwanted elements.
  6. Käytä OHITTAA switch to compare the equalized sound with the original signal.

6.2 FBQ Feedback Detection System

The FBQ system helps identify and eliminate feedback frequencies quickly.

  1. Paina FBQ switch to activate the feedback detection system.
  2. When feedback occurs, the LEDs on the corresponding frequency faders will illuminate brightly, indicating the problematic frequencies.
  3. Gently lower the faders of the illuminated frequencies until the feedback is eliminated.
  4. In normal operation (FBQ active), the fader LEDs can also indicate frequency ranges with the highest energy levels, functioning as an audio analyzer.

6.3 High and Low Cut Filters

These filters help remove undesirable frequencies outside the main audio range.

6.4 Subwoofer Output Control

The dedicated subwoofer output allows for precise bass management.

6.5 Hard Bypass Function

The relay-controlled hard bypass ensures signal integrity and safety.
