4. Betjeningsvejledning
4.1 Frontpanel overview
Figur 2: Detaljeret view of the FBQ2496 front panel controls.
- Niveaumåler: Displays input/output signal levels for both channels. The CLIP indicator illuminates when the signal is too high.
- LÆR knap: Activates the automatic feedback detection and suppression process.
- PANIK knap: 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.
- Digital skærm: Shows parameter values, menu options, and filter numbers.
- Parametric EQ Controls (GAIN, FREQUENCY, BANDWIDTH, PEQ): Used for manual adjustment of parametric filters.
- Roterende encoder: Navigates menus and adjusts parameter values.
- POWER -knap: Tænder/slukker enheden.
4.2 driftstilstande
The FBQ2496 offers several operating modes to suit different applications:
- Automatisk tilstand: Continuously monitors the mix and automatically sets filters to suppress feedback. This is the "set-and-forget" default setting.
- Enkeltbillede-tilstand: 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.
- Tryk på LÆRE 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 PANIK knap.
5. Vedligeholdelse
The Behringer FBQ2496 requires minimal maintenance. Follow these guidelines to ensure its longevity:
- Rensning: Rengør enheden med en blød, tør klud. Brug ikke flydende rengøringsmidler eller aerosoler.
- Ventilation: Ensure that the ventilation slots are free from dust and obstructions.
- Opbevaring: Hvis enheden opbevares i længere tid, skal den afbrydes fra strømmen og opbevares et køligt og tørt sted.
- Firmwareopdateringer: Check the official Behringer website periodically for any available firmware updates. Updates can typically be performed via the MIDI interface.
6. Fejlfinding
| Problem | Mulig årsag | Løsning |
|---|---|---|
| Ingen strøm | Power cable disconnected; faulty power outlet. | Kontrollér strømkablets forbindelse; prøv en anden stikkontakt. |
| Ingen lydudgang | 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. |
| Forvrænget lyd | Input signal too high (clipping); faulty cables. | Reduce input signal level (check CLIP indicator); replace cables. |
