2. Einrichtung

2.1 Auspacken und Aufstellen

Packen Sie vorsichtig aus amplifier and inspect it for any signs of damage. Place the amplifier in a well-ventilated area, preferably in a standard 19-inch equipment rack. Ensure adequate airflow around the unit to prevent overheating.

2.2 Vorderseite überview

• Stromschalter: Schaltet den ampVerstärker EIN/AUS.
• Channel Gain Controls: Adjust the input sensitivity for each of the four channels.
• Signal-LEDs: Indicate the presence of an input signal.
• Clip-LEDs: Illuminate when the output signal is clipping, indicating potential distortion. Reduce the input level if these LEDs light up frequently.
• Betriebs-LEDs: Indicate the operational status of each channel.

2.3 Rückwand überview und Anschlüsse

• 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.
• Modusschalter: Select between Stereo, Parallel, or Bridged operation for each pair of channels (A/B and C/D).
• Crossover-Schalter: Select between Full Range, Low-Cut (for subwoofers), or High-Cut (for top speakers) for each pair of channels.
• Leistungsaufnahme: Standard IEC power connector.
• Leistungsschalter: Provides overload protection.

2.4 Anschließen von Audioquellen und Lautsprechern

Stellen Sie sicher, dass amplifier is turned OFF before making any connections.

1. Eingangsanschlüsse: Schließen Sie Ihre Audioquelle (Mixer, Vorverstärker) an.amplifier, etc.) to the XLR or 1/4-inch TRS combo inputs on the rear panel. Use balanced cables for optimal noise rejection.
2. Lautsprecheranschlüsse: Connect your passive speakers to the Speakon outputs. Ensure correct polarity (+ to + and - to -).
3. Modusauswahl: 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.
   • Überbrückt: 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).
4. Crossover-Einstellungen: Use the crossover switches to optimize the frequency response for your speakers:
   • Vollständige Palette: Sends the full audio spectrum to the speakers.
   • Tief geschnitten: Filters out low frequencies, ideal for top speakers when used with subwoofers.
   • Hochschnitt: Filters out high frequencies, ideal for subwoofers.

3.1 Powering On and Initial Level Setting

1. Ensure all gain controls on the amplifier are set to their minimum position.
2. Turn on your audio source equipment first.
3. Flip the Power Switch on the Behringer NU4-6000 to the ON position. The Power LEDs should illuminate.
4. 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. Wartung

To ensure the longevity and optimal performance of your Behringer NU4-6000 ampVerstärker, befolgen Sie diese Wartungsrichtlinien:

• Reinigung: Reinigen Sie regelmäßig die Außenseite des 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.
• Belüftung: Betreiben Sie immer die amplifier in a well-ventilated environment. Do not block the ventilation openings. Overheating can severely damage the unit.
• Netzkabel: Inspect the power cord periodically for any damage. Replace immediately if frayed or broken.
• Lagerung: Bei längerer Nichtbenutzung lagern Sie die ampDen Verstärker an einem kühlen, trockenen Ort, fern von direkter Sonneneinstrahlung und extremen Temperaturen aufstellen.

5. Fehlerbehebung

If you encounter issues with your Behringer NU4-6000, refer to the following common troubleshooting steps:

• Kein Strom:
  • Prüfen Sie, ob das Netzkabel fest mit beiden Anschlüssen verbunden ist. ampVerstärker und eine funktionierende Steckdose.
  • Stellen Sie sicher, dass die Steckdose aktiv ist.
  • Check the circuit breaker on the rear panel; reset if tripped.
• Kein Ton:
  • 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.
• Überhitzung:
  • Stellen Sie sicher, dass 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.
