2. セットアップ
2.1開梱と配置
慎重に開梱 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 フロントパネルオーバーview
- 電源スイッチ： 回転する ampライターのオン/オフ。
- Channel Gain Controls: Adjust the input sensitivity for each of the four channels.
- 信号LED: Indicate the presence of an input signal.
- クリップ LED: Illuminate when the output signal is clipping, indicating potential distortion. Reduce the input level if these LEDs light up frequently.
- 電源LED: Indicate the operational status of each channel.
2.3リアパネルオーバーview と接続
- 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.
- モードスイッチ: Select between Stereo, Parallel, or Bridged operation for each pair of channels (A/B and C/D).
- クロスオーバースイッチ: Select between Full Range, Low-Cut (for subwoofers), or High-Cut (for top speakers) for each pair of channels.
- 電源入力: Standard IEC power connector.
- 遮断器： Provides overload protection.
2.4 オーディオソースとスピーカーの接続
確実に amplifier is turned OFF before making any connections.
- 入力接続: オーディオソース（ミキサー、プリアンプ、amplifier, etc.) to the XLR or 1/4-inch TRS combo inputs on the rear panel. Use balanced cables for optimal noise rejection.
- スピーカー接続： Connect your passive speakers to the Speakon outputs. Ensure correct polarity (+ to + and - to -).
- モード選択: Use the mode switches to select the desired operation:
- ステレオ： Each channel operates independently, driving a separate speaker.
- 平行： 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.
- ブリッジ: 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).
- クロスオーバー設定: Use the crossover switches to optimize the frequency response for your speakers:
- フルレンジ： Sends the full audio spectrum to the speakers.
- ローカット: Filters out low frequencies, ideal for top speakers when used with subwoofers.
- ハイカット: Filters out high frequencies, ideal for subwoofers.

3. 操作手順
3.1 Powering On and Initial Level Setting
- Ensure all gain controls on the amplifier are set to their minimum position.
- まずオーディオソース機器の電源をオンにします。
- 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. メンテナンス
To ensure the longevity and optimal performance of your Behringer NU4-6000 ampライフライザーを使用する場合は、次のメンテナンス ガイドラインに従ってください。
- クリーニング： 定期的に外装の掃除をしましょう 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.
- 換気： 常に操作してください amplifier in a well-ventilated environment. Do not block the ventilation openings. Overheating can severely damage the unit.
- 電源コード: Inspect the power cord periodically for any damage. Replace immediately if frayed or broken.
- ストレージ： 長期間使用しない場合は、 amp直射日光や極端な温度を避け、涼しく乾燥した場所に保管してください。
5。 トラブルシューティング
If you encounter issues with your Behringer NU4-6000, refer to the following common troubleshooting steps:
- 電源なし:
- 電源コードが両方のコンセントにしっかりと接続されているか確認してください。 amp充電器と機能する電源コンセント。
- 電源コンセントがアクティブであることを確認します。
- Check the circuit breaker on the rear panel; reset if tripped.
- 音が出ない:
- 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.
- 過熱：
- 確実に 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.
