Each of the two channels features:
- 31 Frequency Sliders: Control individual frequency bands from 20 Hz to 20 kHz.
- Input/Output Level Meters: LED indicators for monitoring signal levels.
- Control de guany: Adjusts the overall output level of the channel.
- FBQ Switch: Activates the Feedback Detection System.
- Filtre de tall baix: Sweeps from 25 Hz to 250 Hz to remove unwanted low-frequency rumble.
- Filtre de tall alt: Sweeps from 2.5 kHz to 25 kHz to remove unwanted high-frequency hiss.
- Interruptor de rang: Selects the boost/cut range for the sliders (±6 dB or ±12 dB).
- Interruptor de derivació: Bypasses the equalizer section, allowing the signal to pass through unprocessed.
5.2 Basic Equalization
To adjust the frequency response of your audio:
- Ensure all connections are secure and power is on.
- Estableix el Interval switch to ±12 dB for broader adjustments or ±6 dB for finer control.
- Ajusteu el Guanyar control to achieve an optimal signal level, indicated by the input/output meters. Avoid clipping (red LEDs).
- Mou el 31 Frequency Sliders up or down to boost or cut specific frequencies. Listen carefully to the changes in the audio.
- Utilitza el Tall baix i Tall alt filters to remove undesirable frequencies at the extreme ends of the spectrum.

5.3 Sistema de detecció de retroalimentació FBQ
The FBQ system helps identify and eliminate feedback frequencies:
- Premeu el botó FBQ switch to activate the feedback detection mode.
- When feedback occurs, the LEDs above the corresponding frequency sliders will illuminate brightly.
- Gently lower the slider for the illuminated frequency until the feedback is eliminated or significantly reduced.
- Repeat this process for any other feedback frequencies that appear.
Note: While effective, the FBQ system may require the feedback to be audible before detection. Adjusting sliders proactively based on room acoustics can also help prevent feedback.
6. Manteniment
To ensure the longevity and optimal performance of your FBQ3102HD, follow these maintenance guidelines:
- Neteja: Feu servir un drap suau i sec per netejar l'exterior de la unitat. No utilitzeu productes de neteja abrasius ni dissolvents.
