- Misuratore di livello: Displays input/output signal levels for both channels. The CLIP indicator illuminates when the signal is too high.
- Pulsante IMPARA: Activates the automatic feedback detection and suppression process.
- Pulsante PANICO: Immediately engages maximum feedback suppression in emergency situations.
- Channel Displays (1/L & 2/R): Show the active filters for each channel. Up to 20 filters per channel can be set.
- Display digitale: Shows parameter values, menu options, and filter numbers.
- Parametric EQ Controls (GAIN, FREQUENCY, BANDWIDTH, PEQ): Used for manual adjustment of parametric filters.
- Encoder rotativo: Consente di navigare nei menu e di regolare i valori dei parametri.
- Pulsante di accensione: Accende/spegne l'unità.
Modalità operative 4.2
The FBQ2496 offers several operating modes to suit different applications:
- Modalità automatica: Continuously monitors the mix and automatically sets filters to suppress feedback. This is the "set-and-forget" default setting.
- Modalità scatto singolo: Automatically detects and destroys feedback, then locks the filters until they are manually reset. This is useful for ringing out a room before a performance.
- Manual Mode (Parametric EQ): Allows individual programming of up to 40 fully-parametric filters with adjustable frequency, bandwidth, and gain. This mode is ideal for precise sound shaping.
4.3 Basic Feedback Suppression (Auto Mode)
- Ensure all connections are secure and the unit is powered on.
- Set your mixer's output levels to a moderate level.
- Premere il tasto IMPARARE button to activate Auto Mode. The unit will begin analyzing the audio signal.
- Gradually increase the microphone gain until feedback starts to occur. The FBQ2496 will quickly identify and suppress the feedback frequencies.
- The unit will automatically set ultra-narrow FBQ filters to eliminate the feedback while preserving the sonic quality of your signal.
- For immediate feedback emergencies, press the PANICO pulsante.

6. Risoluzione Dei Problemi
| Problema | Possibile causa | Soluzione |
|---|---|---|
| Nessun potere | Power cable disconnected; faulty power outlet. | Controllare il collegamento del cavo di alimentazione; provare una presa di corrente diversa. |
| Nessuna uscita audio | Incorrect cable connections; unit in Bypass mode; input signal too low. | Verify all audio cable connections; ensure unit is not in Bypass mode; increase input signal level. |
| Feedback not suppressed | LEARN mode not active; filters are full; extreme acoustic conditions. | Activate LEARN mode; reset filters if necessary; adjust microphone placement or gain. |
| Audio distorto | Input signal too high (clipping); faulty cables. | Reduce input signal level (check CLIP indicator); replace cables. |
