Klark Teknik DN100 V2 アクティブダイレクトボックス ユーザーマニュアル

1. はじめに

The Klark Teknik DN100 V2 is a high-performance, 1-channel active direct injection (DI) box designed to convert unbalanced, high-impedance instrument signals into balanced, low-impedance signals suitable for direct connection to mixing consoles, preamplifiers, or other professional audio equipment. Its robust construction and phantom-powered active circuitry ensure clean headroom and wide dynamic range, making it ideal for both live sound and studio recording applications.

2. 主な特徴

• 1-channel Active Direct Box: Provides a single channel for converting instrument signals.
• Phantom-powered Operation: Draws power directly from the mixing console's 48V phantom power, eliminating the need for batteries or external power supplies.
• 1/4" TRS Input: Accommodates standard instrument cables for connecting guitars, keyboards, and other audio sources.
• XLR出力： Delivers a balanced, low-impedance signal for long cable runs without signal degradation.
• Earth Lift Switch: Helps eliminate ground loop hum by disconnecting the input ground from the output ground.
• -20dB パッドスイッチ: Attenuates high-level input signals to prevent clipping and distortion, ensuring optimal signal integrity.

3. セットアップと接続

Proper setup of the DN100 V2 is crucial for optimal performance. Follow these steps to connect your direct box:

1. Connect Instrument to Input: Use a standard 1/4" TRS or TS cable to connect your instrument (e.g., guitar, bass, keyboard, or guitar modeler) to the 入力 jack on the DN100 V2.
2. ミキサー/プリに接続するamp: Use a balanced XLR cable to connect the 出力 XLR jack of the DN100 V2 to an available microphone input on your mixing console or audio interface.
3. Engage Phantom Power: Activate the 48V phantom power on the corresponding channel of your mixing console. The DN100 V2 will automatically power on.
4. Parallel Output (Optional): The DN100 V2 features a parallel 1/4" TRS output. This allows you to send the original instrument signal to an amplifier or another input source simultaneously. Connect a 1/4" TRS or TS cable from the リンク output to your ampライターの入力。

4. 操作

Once connected and powered, the DN100 V2 is ready for operation. Understanding its switches will help optimize your signal.

4.1. -20dB Pad Switch

の -20dBパッド switch is used to attenuate the input signal by 20 decibels. This is particularly useful when connecting high-output sources, such as active bass guitars, keyboards, or line-level signals, to prevent the DI box from clipping or distorting. If you notice distortion or a very hot signal at your mixer, engage this switch.

4.2. Earth Lift Switch

の Earth Lift switch helps to eliminate hum or buzzing noises caused by ground loops. A ground loop occurs when there are multiple ground paths in an audio system, creating a current flow that manifests as audible noise. If you experience hum, try engaging the Earth Lift switch. This disconnects the ground connection between the input and output, often resolving the issue. If the hum persists, ensure all equipment is properly grounded and check other cable connections.

5. メンテナンス

The Klark Teknik DN100 V2 is built for durability and requires minimal maintenance. To ensure its longevity and optimal performance:

• クリーニング： 本体の外側は、柔らかく乾いた布で拭いてください。研磨剤入りの洗剤、溶剤、過度の湿気は、仕上げや内部部品を損傷する可能性があるため、使用しないでください。
• ストレージ： 使用していないときは、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。
• ケーブル管理 Always use high-quality cables and ensure they are not kinked or excessively bent, which can lead to internal damage over time.

6。 トラブルシューティング

If you encounter issues with your DN100 V2, consider the following common troubleshooting steps:

• 信号なし：
  • Ensure 48V phantom power is engaged on your mixer channel.
  • Check all cable connections (input, output, and link) for proper seating and integrity.
  • Verify that the instrument connected to the input is functioning correctly.
  • 配線に問題がないか確認するために、さまざまなケーブルでテストします。
• ハム音またはブーンという音:
  • 関与する Earth Lift スイッチ。
  • Ensure all audio equipment in the signal chain is properly grounded.
  • Check for nearby electrical interference from power cables or other electronic devices.
• 歪んだ信号:
  • 関与する -20dBパッド switch if connecting a high-output instrument.
  • Reduce the output level of your instrument.
  • Check the input gain settings on your mixing console to ensure they are not set too high.
