2. Setélan
2.1 Ngabongkar sareng Nempatkeun
Taliti ngabongkar 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 Panel hareup Leuwihview
- Saklar kakuatan: Ngahurungkeun ampLifier ON / OFF.
- Channel Gain Controls: Adjust the input sensitivity for each of the four channels.
- Sinyal LEDs: Indicate the presence of an input signal.
- Klip LEDs: Illuminate when the output signal is clipping, indicating potential distortion. Reduce the input level if these LEDs light up frequently.
- LEDs kakuatan: Indicate the operational status of each channel.
2.3 Panel Rear Leuwihview jeung Sambungan
- 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.
- Saklar Mode: Select between Stereo, Parallel, or Bridged operation for each pair of channels (A/B and C/D).
- Saklar Crossover: Select between Full Range, Low-Cut (for subwoofers), or High-Cut (for top speakers) for each pair of channels.
- Input kakuatan: Standard IEC power connector.
- Pamutus Sirkuit: Provides overload protection.
2.4 Connecting Audio Sources and Speakers
Pastikeun amplifier is turned OFF before making any connections.
- Sambungan Input: Sambungkeun sumber audio anjeun (mixer, preamplifier, etc.) to the XLR or 1/4-inch TRS combo inputs on the rear panel. Use balanced cables for optimal noise rejection.
- Sambungan Speaker: Connect your passive speakers to the Speakon outputs. Ensure correct polarity (+ to + and - to -).
- Pilihan Mode: Use the mode switches to select the desired operation:
- Stereo: Each channel operates independently, driving a separate speaker.
- Paralel: 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.
- Sasak: 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).
- Setélan Crossover: Use the crossover switches to optimize the frequency response for your speakers:
- rentang pinuh: Sends the full audio spectrum to the speakers.
- Low-Cut: Filters out low frequencies, ideal for top speakers when used with subwoofers.
- Potongan Tinggi: Filters out high frequencies, ideal for subwoofers.

3. Parentah Operasi
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.

5. Cara ngungkulan
If you encounter issues with your Behringer NU4-6000, refer to the following common troubleshooting steps:
- Henteu aya kakuatan:
- Pariksa naha kabel listrik parantos disambungkeun pageuh kana duanana amplifier sareng stop kontak listrik anu tiasa dianggo.
- Pariksa yén outlet listrik aktip.
- Check the circuit breaker on the rear panel; reset if tripped.
- Henteu aya sora:
- 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.
- Overheating:
- Pastikeun 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.
