2. Setup
2.1 Spakkjar u Tqegħid
Ippakkja b'attenzjoni l- 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 Front Panel Overview
- Swiċċ tal-Enerġija: Dawwar il- amplifier ON/OFF.
- Kontrolli tal-Qligħ tal-Kanal: Adjust the input sensitivity for each of the four channels.
- LEDs tas-sinjali: 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.
- LEDs tal-qawwa: Indicate the operational status of each channel.
2.3 Panel ta' wara Overview u Konnessjonijiet
- 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.
- Swiċċijiet tal-Modalità: Select between Stereo, Parallel, or Bridged operation for each pair of channels (A/B and C/D).
- Swiċċijiet Crossover: Select between Full Range, Low-Cut (for subwoofers), or High-Cut (for top speakers) for each pair of channels.
- Input ta' Enerġija: Standard IEC power connector.
- Circuit Breaker: Provides overload protection.
2.4 Connecting Audio Sources and Speakers
Tiżgura l- amplifier is turned OFF before making any connections.
- Konnessjonijiet tad-dħul: Qabbad is-sors awdjo tiegħek (mixer, preamplifier, etc.) to the XLR or 1/4-inch TRS combo inputs on the rear panel. Use balanced cables for optimal noise rejection.
- Konnessjonijiet tal-Ispeaker: Connect your passive speakers to the Speakon outputs. Ensure correct polarity (+ to + and - to -).
- Għażla tal-Modalità: 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.
- Imqabbad: 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).
- Settings tal-crossover: Use the crossover switches to optimize the frequency response for your speakers:
- Firxa Sħiħa: Sends the full audio spectrum to the speakers.
- Low-Cut: Filters out low frequencies, ideal for top speakers when used with subwoofers.
- Qtugħ Għoli: Filters out high frequencies, ideal for subwoofers.

3. Istruzzjonijiet Operattivi
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. Manutenzjoni
To ensure the longevity and optimal performance of your Behringer NU4-6000 amplifer, segwi dawn il-linji gwida tal-manutenzjoni:
- Tindif: Naddaf regolarment il-barra tal- 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.
- Ventilazzjoni: Dejjem tħaddem il- amplifier in a well-ventilated environment. Do not block the ventilation openings. Overheating can severely damage the unit.
- Korda tal-Enerġija: Inspect the power cord periodically for any damage. Replace immediately if frayed or broken.
- Ħażna: Meta ma tkunx qed tużaha għal perjodi twal, aħżenha amplifier f'post frisk u niexef, 'il bogħod mix-xemx diretta u minn temperaturi estremi.
5 Issolvi l-problemi
If you encounter issues with your Behringer NU4-6000, refer to the following common troubleshooting steps:
- Ebda Qawwa:
- Iċċekkja jekk il-korda tal-enerġija hijiex imqabbda sew maż-żewġ amplifier and a working power outlet.
- Ivverifika li l-iżbokk tad-dawl huwa attiv.
- Check the circuit breaker on the rear panel; reset if tripped.
- Ebda Ħsejjes:
- 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 ampL-impedenza u l-qawwa tal-ħruġ tal-lifer.
- Is-sħana żejda:
- Tiżgura l- 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.
