• Input/Output Level Meter: 12-segment LED display for monitoring signal levels.
• Input Gain Control: Justerer indgangsfølsomheden for hver kanal.
• Low Cut Filter: Sweeps from 10 Hz to 400 Hz, removing unwanted low frequencies.
• High Cut Filter: Sweeps from 2.5 kHz to 30 kHz, removing unwanted high frequencies.
• FBQ Switch: Activates the FBQ Feedback Detection System.
• Områdekontakt: 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 Bagpanel overview

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

• Afbryderen: Tænder eller slukker for enheden.
• AC-indgang: Standard IEC connector for the power cable.
• Inputs (Channel 1 & 2): Balanced XLR and 1/4" TRS connectors for audio input.
• Outputs (Channel 1 & 2): Balanced XLR and 1/4" TRS connectors for audio output.
• Sub Out: Mono XLR output for connecting a subwoofer.
• Subwoofer niveau kontrol: Adjusts the output level of the subwoofer signal.
• Subwoofer Crossover Frequency Control: Sets the crossover point for the subwoofer output.

5. Opsætning

Proper setup ensures optimal performance and prevents damage to your equipment.

5.1 Strømtilslutning

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. Sæt den anden ende af strømkablet i en passende stikkontakt.

5.2 Lydforbindelser

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 INDGANGE (Channel 1 and 2) on the rear panel of the FBQ3102 using XLR or 1/4" TRS cables.
2. Tilslut OUTPUTS (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 UD (XLR) to the input of your active subwoofer or subwoofer amplivligere.

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

6. Betjeningsvejledning

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. Juster INPUTGIVNING controls so that the input/output level meters show a healthy signal without clipping (red LEDs).
4. Brug RANGE switch to select either ±6 dB or ±12 dB adjustment range for the frequency faders. Start with ±6 dB for finer control.
5. Justér den enkelte FREQUENCY FADERS to shape your sound. Boost frequencies to emphasize them or cut frequencies to reduce unwanted elements.
6. Brug 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. Tryk på 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.

• Drej på LAVT SKÆRING knob clockwise to gradually remove low-end rumble or unwanted bass frequencies.
• Drej på HIGH CUT knob counter-clockwise to remove hiss or harsh high frequencies.

6.4 Subwoofer Output Control

The dedicated subwoofer output allows for precise bass management.

• Juster SUBWOOFER NIVEAU control to set the desired volume for your subwoofer.
• Brug 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. Vedligeholdelse

• Rensning: Clean the unit with a soft, dry cloth. Do not use liquid cleaners or solvents.
• Ventilation: Sørg for tilstrækkelig ventilation omkring enheden for at forhindre overophedning. Bloker ikke ventilationsåbningerne.
• Opbevaring: Hvis enheden opbevares i en længere periode, skal den afbrydes fra strømmen og opbevares et tørt og støvfrit miljø.
• Service: Refer all servicing to qualified service personnel. Do not attempt to service the unit yourself.
