2. Opstelling
2.1 Uitpak en plasing
Pak die versigtig uit amplifier and inspect it for any signs of damage. Place the ampBêre die verkoeler in 'n goed geventileerde area, verkieslik in 'n standaard 19-duim toerustingrak. Verseker voldoende lugvloei rondom die eenheid om oorverhitting te voorkom.
2.2 Voorpaneel oorview
- Krag skakelaar: Draai die ampverligter AAN/UIT.
- Kanaalwinskontroles: Adjust the input sensitivity for each of the four channels.
- Sein LED's: Indicate the presence of an input signal.
- Knip LED's: Illuminate when the output signal is clipping, indicating potential distortion. Reduce the input level if these LEDs light up frequently.
- Krag LED's: Indicate the operational status of each channel.
2.3 Agterpaneel oorview en verbindings
- Inputs (CH A, CH B, CH C, CH D): XLR and 1/4-inch TRS combo jacks for connecting audio sources.
- Outputs (CH A, CH B, CH C, CH D): Speakon connectors for connecting speakers.
- Modusskakelaars: Select between Stereo, Parallel, or Bridged operation for each pair of channels (A/B and C/D).
- Oorkruisskakelaars: Select between Full Range, Low-Cut (for subwoofers), or High-Cut (for top speakers) for each pair of channels.
- Kragtoevoer: Standard IEC power connector.
- Stroombreker: Bied oorbelastingbeskerming.
2.4 Verbinding van klankbronne en luidsprekers
Verseker die amplifier is turned OFF before making any connections.
- Invoerverbindings: Koppel jou klankbron (menger, voorversterker)amplifier, etc.) to the XLR or 1/4-inch TRS combo inputs on the rear panel. Use balanced cables for optimal noise rejection.
- Luidsprekerverbindings: Connect your passive speakers to the Speakon outputs. Ensure correct polarity (+ to + and - to -).
- Moduskeuse: Use the mode switches to select the desired operation:
- stereo: Each channel operates independently, driving a separate speaker.
- Parallel: Input signal from Channel A is sent to both Channel A and Channel B outputs (and similarly for C/D), allowing both channels to drive speakers with the same mono signal.
- Oorbrug: Combines the power of two channels (A+B or C+D) to drive a single, higher-power speaker (typically a subwoofer). Ensure the speaker impedance is compatible with bridged mode (usually 4 or 8 Ohms).
- Crossover-instellings: Use the crossover switches to optimize the frequency response for your speakers:
- Volle omvang: Sends the full audio spectrum to the speakers.
- Lae sny: Filters out low frequencies, ideal for top speakers when used with subwoofers.
- Hoë snit: Filters out high frequencies, ideal for subwoofers.

3. Bedryfsinstruksies
3.1 Powering On and Initial Level Setting
- Ensure all gain controls on the amplifier are set to their minimum position.
- Turn on your audio source equipment first.
- Flip the Power Switch on the Behringer NU4-6000 to the ON position. The Power LEDs should illuminate.
- Slowly increase the gain controls for each channel until the desired volume is reached. Monitor the Signal and Clip LEDs to avoid distortion.
3.2 Understanding "Zero-Attack" Limiters
The "Zero-Attack" limiters are designed to provide maximum output level with reliable overload protection. They automatically detect when the signal is approaching clipping and dynamically reduce the gain to prevent distortion and protect your speakers.
3.3 Class-D Technology and Switch-Mode Power Supply
The NU4-6000 utilizes revolutionary High-Density Class-D amplifier technology, which ensures cool-running operation with "near-zero" thermal buildup. Coupled with an ultra-efficient switch-mode power supply, the amplifier delivers noise-free audio, superior transient response, and low power consumption, making it ideal for extended use.

4. Onderhoud
To ensure the longevity and optimal performance of your Behringer NU4-6000 ampLifier, volg hierdie onderhoudsriglyne:
- Skoonmaak: Maak gereeld die buitekant van die skoon amplifier with a soft, dry cloth. Avoid using abrasive cleaners or solvents. Ensure ventilation grilles are free from dust and debris to maintain proper airflow.
- Ventilasie: Bedryf altyd die amplifier in a well-ventilated environment. Do not block the ventilation openings. Overheating can severely damage the unit.
- Kragkabel: Inspect the power cord periodically for any damage. Replace immediately if frayed or broken.
- Berging: Wanneer dit nie vir lang tye gebruik word nie, bêre die ampVerwyderaar op 'n koel, droë plek, weg van direkte sonlig en uiterste temperature.
5. Probleemoplossing
If you encounter issues with your Behringer NU4-6000, refer to the following common troubleshooting steps:
- Geen krag:
- Kontroleer of die kragkabel stewig aan beide die amp'n kragtoevoer en 'n werkende kragpunt.
- Verifieer dat die aansluiting aktief is.
- Check the circuit breaker on the rear panel; reset if tripped.
- Geen klank:
- Ensure all audio input and speaker output cables are correctly and securely connected.
- Verify that the input source is active and sending a signal.
- Check the gain controls on the amplifier; ensure they are not set to minimum.
- Confirm that the correct mode (Stereo, Parallel, Bridged) is selected for your setup.
- Distorted Sound / Clip LED On:
- Reduce the input gain on the amplifier or the output level from your audio source.
- Ensure your speakers are correctly matched to the amplifier's impedance and power output.
- Oorverhitting:
- Verseker die amplifier has adequate ventilation and that no vents are blocked.
- Check speaker impedance; operating with too low an impedance can cause overheating.
- Reduce the overall volume or continuous high-power operation.
If the problem persists after trying these steps, please contact Behringer customer support.
