• Ki malosiaga: Liliu le ampLifier ON/OFF.
• Pulea o le Mauaina o Alavai: Adjust the input sensitivity for each of the four channels.
• LED faailoilo: Indicate the presence of an input signal.
• Kilipa LED: Illuminate when the output signal is clipping, indicating potential distortion. Reduce the input level if these LEDs light up frequently.
• LED Malosiaga: Indicate the operational status of each channel.

2.3 Fa'asaga i tuaview ma So'oga

• 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.
• Suiga Faiga: Select between Stereo, Parallel, or Bridged operation for each pair of channels (A/B and C/D).
• Suiga fa'asagatau: Select between Full Range, Low-Cut (for subwoofers), or High-Cut (for top speakers) for each pair of channels.
• Malosiaga Ulufale: Standard IEC power connector.
• Soli matagaluega: Provides overload protection.

2.4 Connecting Audio Sources and Speakers

Ia mautinoa le amplifier is turned OFF before making any connections.

1. So'oga fa'aofi: Fa'afeso'ota'i lau puna leo (mixer, preamplifier, etc.) to the XLR or 1/4-inch TRS combo inputs on the rear panel. Use balanced cables for optimal noise rejection.
2. Feso'ota'iga a le Fofoga Fetalai: Connect your passive speakers to the Speakon outputs. Ensure correct polarity (+ to + and - to -).
3. Filifiliga ala: Use the mode switches to select the desired operation:
   • Stereo: Each channel operates independently, driving a separate speaker.
   • Fa'atasi: 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.
   • Fa'atasi: 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. Fa'asagaga Fa'asaga: Use the crossover switches to optimize the frequency response for your speakers:
   • Vaega atoa: Sends the full audio spectrum to the speakers.
   • Maualalo-Otioti: Filters out low frequencies, ideal for top speakers when used with subwoofers.
   • Oti maualuga: 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.

  • Siaki pe ua fa'apipi'i lelei le uaea eletise i itu uma e lua ample eletise ma se paipa eletise o loʻo galue.
  • Faʻamaonia o loʻo ola le afi eletise.
  • Check the circuit breaker on the rear panel; reset if tripped.
• Leai se leo:
  • 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.
• Ova le vevela:
  • Ia mautinoa le 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.
