Un enchufe con conexión a tierra tiene dos clavijas y una tercera clavija de conexión a tierra. La clavija ancha o la tercera clavija se proporcionan para su seguridad. Si el enchufe proporcionado no encaja en su tomacorriente, consulte a un electricista para que reemplace el tomacorriente obsoleto.
• Proteja el cable de alimentación para que no sea pisado ni aplastado, especialmente en los enchufes, receptáculos y en el punto donde sale del aparato.
• Utilice únicamente accesorios especificados por el fabricante.
• Desenchufe este aparato durante tormentas eléctricas o cuando no lo utilice durante períodos prolongados.
• Encargue todas las tareas de mantenimiento a personal técnico cualificado. Se requiere realizar el mantenimiento cuando el aparato haya sufrido algún daño, como por ejemplo si el cable de alimentación o el enchufe están dañados, si se ha derramado líquido o han caído objetos en el interior del aparato, si el aparato ha estado expuesto a la lluvia o la humedad, si no funciona con normalidad o si se ha caído.

3. Configuración

3.1 Desembalaje

Carefully unpack your FBQ6200. Inspect the unit for any signs of damage that may have occurred during transit. If damage is found, contact your dealer immediately. Retain the original packing materials for future shipping or storage.

3.2 Conexiones

The FBQ6200 offers flexible connectivity options. Ensure all audio equipment is powered off before making any connections.

• Entradas de audio: Connect your audio source (e.g., mixer output) to the FBQ6200's inputs using balanced XLR or 1/4" TRS cables. The unit features two channels for stereo operation.
• Salidas de audio: Connect the FBQ6200's outputs to your amplifier or next processing stage using balanced XLR or 1/4" TRS cables.
• Salida de subwoofer: A dedicated mono subwoofer output is provided for connecting to a powered subwoofer or subwoofer amplifier. This output features an adjustable crossover frequency.
• Conexiones RCA: While the primary connectors are XLR and 1/4" TRS, RCA adapters can be used for compatibility with RCA-equipped gear. Ensure proper grounding to avoid hum and noise.

3.3 Conexión de alimentación

Connect the supplied AC power cord to the FBQ6200's power inlet and then to a suitable AC power outlet. Ensure the voltage matches the unit's requirements. Always power on your equalizer after your mixer and before your power amplifiers. Power off in the reverse order.

4. Operating the FBQ6200

The FBQ6200 offers a range of controls for precise audio shaping and system protection.

4.1 Controles del panel frontalview

• Frequency Sliders: Each channel features 31 illuminated sliders, allowing you to boost or cut specific frequency bands by up to ±12 dB. The center position is flat (0 dB).
• FBQ Feedback Detection System: Activate the FBQ button. The LEDs on the frequency sliders will illuminate brightly at the frequencies where feedback is occurring, allowing for quick identification and reduction. This system can also function as an audio analyzer.
• Limitadores: Each channel has a dedicated limiter with a threshold control and gain reduction meters. Adjust the threshold to prevent signal peaks from exceeding a set level, protecting your sound system from overload and distortion.
• Generador de ruido rosa: Press the PINK NOISE button to activate the internal pink noise generator. This signal can be used in conjunction with the FBQ system or an external real-time analyzer to equalize your sound system to the room acoustics.
• Controles de nivel de entrada/salida: Use these controls to adjust the overall input and output gain of each channel. The 8-digit LED meters provide accurate visual feedback for level setting. Aim for levels that are strong but do not consistently peak into the red.
• Filtros de corte bajo/corte alto: These filters allow you to remove unwanted low-frequency rumble or high-frequency hiss from your signal. The low cut filter typically removes frequencies below 20-30 Hz, while the high cut filter removes frequencies above 18-20 kHz.
• Interruptor de derivación: Engages or disengages the equalizer's processing, allowing for quick A/B comparison between the processed and unprocessed signal.
• Crossover de subwoofer: Adjust the crossover frequency for the dedicated subwoofer output, allowing you to tailor the low-frequency response of your system.

4.2 Basic Equalization Procedure

1. Start with all frequency sliders at the 0 dB (center) position.
2. Set input and output levels appropriately, ensuring no clipping.
3. For feedback control, activate the FBQ system. Identify illuminated sliders and gently reduce the gain for those specific frequencies until feedback is eliminated.
4. For room equalization, activate the pink noise generator. Use the FBQ system as a visual aid or an external analyzer to identify resonant frequencies in the room and adjust the corresponding sliders to achieve a flatter frequency response.
5. Use the low and high cut filters to clean up the signal as needed.
6. Engage the limiters and set their thresholds to prevent accidental overloads.

5. Mantenimiento

The Behringer FBQ6200 is designed for reliable operation with minimal maintenance.

• Limpieza: Disconnect the unit from power before cleaning. Use a soft, dry cloth to wipe down the exterior. Avoid abrasive cleaners or solvents that could damage the finish or controls.
• Ventilación: Ensure that the ventilation openings are not obstructed. Proper airflow is crucial to prevent overheating, especially during extended operation.
• Almacenamiento: If storing the unit for an extended period, place it back in its original packaging or a protective case to prevent dust accumulation and physical damage.

6. Solución de problemas

If you encounter issues with your FBQ6200, consult the following common troubleshooting steps:

• Sin salida de sonido:
  • Check all audio cable connections (inputs and outputs) to ensure they are secure and correctly routed.
  • Verify that the FBQ6200 is powered on and its input/output levels are not set to minimum.
  • Ensure the Bypass switch is not engaged if you expect processed sound.
  • Check the power and signal status of connected equipment (mixer, amplifier, speakers).
• Distortion or Unwanted Noise:
  • Check input and output levels. Excessive gain staging can lead to clipping and distortion. Adjust levels so meters do not consistently hit the red.
  • Ensure all cables are in good condition and properly shielded. Faulty cables can introduce noise.
  • Verify proper grounding of all audio equipment to prevent hum.
  • If experiencing persistent noise in one channel, try swapping cables or inputs to isolate the source. If the noise follows the unit, contact support.
• Problemas de comentarios:
  • Activate the FBQ Feedback Detection System. Reduce the gain on the illuminated frequency sliders until feedback is controlled.
  • Ensure microphone placement and speaker positioning are optimized to minimize feedback potential.
• La unidad se siente caliente:
  • Ensure adequate ventilation around the unit. Do not place it in an enclosed space without proper airflow.
  • Avoid stacking other heat-generating equipment directly on top of the FBQ6200.
  • If the unit becomes excessively hot and causes operational issues, discontinue use and contact support.
