- ການເຊື່ອມຕໍ່ຂາເຂົ້າ: ເຊື່ອມຕໍ່ແຫຼ່ງສຽງຂອງທ່ານ (ເຄື່ອງປະສົມສຽງ, ເຄື່ອງປະສົມສຽງກ່ອນ)amplifier, etc.) to the XLR or 1/4-inch TRS combo inputs on the rear panel. Use balanced cables for optimal noise rejection.
- ການເຊື່ອມຕໍ່ລຳໂພງ: Connect your passive speakers to the Speakon outputs. Ensure correct polarity (+ to + and - to -).
- ການເລືອກໂໝດ: Use the mode switches to select the desired operation:
- ສະເຕກ: Each channel operates independently, driving a separate speaker.
- ຂະຫນານ: 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.
- ຂົວແລ້ວ: 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).
- ການຕັ້ງຄ່າ Crossover: Use the crossover switches to optimize the frequency response for your speakers:
- ຂອບເຂດເຕັມ: Sends the full audio spectrum to the speakers.
- ຕັດຕ່ຳ: Filters out low frequencies, ideal for top speakers when used with subwoofers.
- ຕັດສູງ: Filters out high frequencies, ideal for subwoofers.

3.1 Powering On and Initial Level Setting
- Ensure all gain controls on the amplifier are set to their minimum position.
- ເປີດອຸປະກອນແຫຼ່ງສຽງຂອງທ່ານກ່ອນ.
- 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. ການແກ້ໄຂບັນຫາ
If you encounter issues with your Behringer NU4-6000, refer to the following common troubleshooting steps:
- ບໍ່ມີພະລັງງານ:
- ກວດສອບວ່າສາຍໄຟໄດ້ເຊື່ອມຕໍ່ກັບທັງສອງຢ່າງແໜ້ນໜາແລ້ວຫຼືບໍ່ amplifier ແລະປລັກສຽບໄຟເຮັດວຽກ.
- ກວດສອບເບິ່ງວ່າປລັກສຽບໄຟເປີດໃຊ້ງານຢູ່.
- Check the circuit breaker on the rear panel; reset if tripped.
- ບໍ່ມີສຽງ:
- 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.
- ຄວາມຮ້ອນເກີນ:
- ຮັບປະກັນ 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.
