• Kontwòl pwogrè Antre: Ajiste sansiblite antre a pou chak kanal.
• Filtè Low Cut: Sweeps from 10 Hz to 400 Hz, removing unwanted low frequencies.
• Filtè koupe segondè: Sweeps from 2.5 kHz to 30 kHz, removing unwanted high frequencies.
• FBQ Switch: Activates the FBQ Feedback Detection System.
• Chanjman ranje: Selects the fader boost/cut range (±6 dB or ±12 dB).
• Bypass switch: Engages or disengages the equalizer effect for A/B comparison.
• Frequency Faders: 31 faders per channel for adjusting specific frequency bands. LEDs on these faders indicate feedback frequencies when FBQ is active.

4.2 Dèyè Panel Overview

The rear panel houses all audio input and output connections, as well as the power input.

5. Enstalasyon

Bon konfigirasyon asire pi bon pèfòmans epi anpeche domaj nan ekipman ou an.

5.1 Koneksyon pouvwa

1. Ensure the FBQ3102's power switch is in the OFF position.
2. Connect the supplied AC power cable to the IEC input on the rear panel of the unit.
3. Branche lòt bout kab kouran an nan yon priz kouran AC ki apwopriye.

5.2 Koneksyon Audio

The FBQ3102 features servo-balanced inputs and outputs, supporting both balanced XLR and 1/4" TRS connections. Unbalanced connections can also be used, with the unit automatically adjusting the signal level.

1. Connect the output of your mixing console or audio source to the ENTRÈ (Channel 1 and 2) on the rear panel of the FBQ3102 using XLR or 1/4" TRS cables.
2. Konekte a SOTI (Channel 1 and 2) of the FBQ3102 to the inputs of your power amplifier or next device in the signal chain using XLR or 1/4" TRS cables.
3. For subwoofer integration, connect the SUB SOTI (XLR) to the input of your active subwoofer or subwoofer amplifier.

Nòt: Always make sure all audio connections are secure before powering on the unit.

6. Operasyon Enstriksyon

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. Ajiste a ANTRAN GAIN controls so that the input/output level meters show a healthy signal without clipping (red LEDs).
4. Sèvi ak la NIVO switch to select either ±6 dB or ±12 dB adjustment range for the frequency faders. Start with ±6 dB for finer control.
5. Adjust the individual FREQUENCY FADERS to shape your sound. Boost frequencies to emphasize them or cut frequencies to reduce unwanted elements.
6. Sèvi ak la BYPASS 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. Peze a 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.

• Vire a LOW CUT knob clockwise to gradually remove low-end rumble or unwanted bass frequencies.
• Vire a Koupe segondè knob counter-clockwise to remove hiss or harsh high frequencies.

6.4 Subwoofer Output Control

The dedicated subwoofer output allows for precise bass management.

• Ajiste a NIVO SUBWOOFER control to set the desired volume for your subwoofer.
• Sèvi ak la SUBWOOFER CROSSOVER FREQUENCY control to define the upper frequency limit for the subwoofer signal. This ensures that only low frequencies are sent to the subwoofer, optimizing system performance.

6.5 Hard Bypass Function

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

• In the event of power loss or faulty power delivery, the equalizer automatically switches to bypass mode, allowing the audio signal to pass through unaffected.
• During power-up, a slight delay prevents dangerous switch-on thumps, protecting connected equipment.

7. Antretyen

• Netwayaj: Clean the unit with a soft, dry cloth. Do not use liquid cleaners or solvents.
• Vantilasyon: Asire w ke gen ase vantilasyon toutotou aparèy la pou anpeche l chofe twòp. Pa bloke ouvèti vantilasyon yo.
• Depo: If storing the unit for an extended period, disconnect it from power and store it in a dry, dust-free environment.
• Sèvis: Refer all servicing to qualified service personnel. Do not attempt to service the unit yourself.
