1. 開梱と初期検査

Carefully remove the Scarlett OctoPre Dynamic from its packaging. Ensure all included components are present: the Scarlett OctoPre Dynamic unit, a Getting Started Guide, and a Power Cable. Inspect the unit for any signs of physical damage. If any damage is found, contact your retailer immediately.

2. 物理的な接続

The Scarlett OctoPre Dynamic connects to your audio interface primarily via ADAT optical cables. It also features various analog inputs and outputs.

1. 電源接続: Connect the supplied power cable to the unit and a suitable power outlet.
2. ADAT Connection: Use an ADAT optical cable (not included) to connect the ADAT OUT port on the Scarlett OctoPre Dynamic to the ADAT IN port on your audio interface. If your interface supports dual ADAT, you may use a second cable for additional channels at higher sampルレート。
3. Word Clock (Optional): For advanced synchronization with other digital devices, connect a Word Clock cable from your master clock device to the Word Clock IN on the OctoPre Dynamic, and/or from the OctoPre Dynamic's Word Clock OUT to other devices.
4. アナログ入力：
   • Front Panel Inputs (1-2): These are combo XLR/TRS inputs for microphones, line-level sources, or instruments.
   • Rear Panel Inputs (3-8): These are combo XLR/TRS inputs for microphones or line-level sources.
5. ライン出力： The eight balanced line outputs can be used to send audio to a mixing console, monitor speakers, or other outboard gear.

3. ソフトウェアのセットアップ

The Scarlett OctoPre Dynamic is designed to work with any ADAT-equipped audio interface. Configuration and routing are typically managed through your primary audio interface's control software (e.g., Focusrite Control for Scarlett interfaces). Ensure your audio interface drivers are up-to-date.

• ドライバーのインストール: Install the latest drivers for your primary audio interface from the manufacturer's webサイト。
• ソフトウェア制御： Open your audio interface's control software. You should see the additional ADAT inputs from the Scarlett OctoPre Dynamic available for routing and monitoring.
• Sample Rate Synchronization: sを設定するample rate in your DAW and your audio interface's control software to match. The Scarlett OctoPre Dynamic supports samp最大 192 kHz のレート。

Operating the Scarlett OctoPre Dynamic

フロントパネルコントロール

• ゲインノブ: Adjust the input gain for each of the eight channels.
• PAD Switches: Engage the PAD switch for inputs with very high signal levels to prevent clipping.
• INST Switches (Inputs 1-2): Engage for direct connection of instruments (guitars, basses) to optimize impedance.
• 48Vファンタム電源: Individual 48V phantom power switches are available for each channel to power condenser microphones.
• Compression Controls: Each channel features a single-knob analog compressor.
  • COMPノブ: 圧縮の量を調整します。
  • さらにボタン: Doubles the compression ratio for a more pronounced effect.
  • O/L LED: Indicates overload/clipping.
• LED Input Metering: A 5-segment LED meter for each channel provides visual feedback on input levels.
• Sample Rate/Sync Indicators: LEDs display the current sample rate and synchronization status.
• 電源スイッチ： ユニットの電源をオンまたはオフにします。

背面パネルの接続

• マイク/ライン入力（3～8）： Combo XLR/TRS jacks for connecting microphones or line-level sources.
• Line Outputs (1-8): Balanced TRS outputs for sending audio signals.
• ADAT Optical I/O: Used for digital audio transfer to and from your main audio interface.
• Word Clock I/O: 外部クロック同期用の BNC コネクタ。

ユニットの使用

1. マイク/楽器を接続する: Plug your microphones into the XLR inputs or instruments into the TRS inputs (1-2).
2. ファンタム電源を適用する: If using condenser microphones, activate the 48V phantom power for the respective channels.
3. ゲインを調整: Slowly increase the gain for each channel while monitoring the LED meters to achieve a healthy signal level without clipping.
4. Apply Compression: Use the COMP knob to add analog compression. Engage the 'MORE' button for a stronger compression effect.
5. モニターオーディオ: Route the ADAT inputs from the OctoPre Dynamic within your DAW or audio interface control software to monitor the incoming audio.

メンテナンス

• クリーニング： Use a dry, soft cloth to clean the exterior of the unit. Avoid liquid cleaners or abrasive materials.
• 換気： 過熱を防ぐため、本体の周囲に十分な換気を確保してください。通気口を塞がないでください。
• 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。

トラブルシューティング

• オーディオ信号なし:
  • Check all cable connections (power, ADAT, audio cables).
  • Verify phantom power is engaged for condenser microphones.
  • Ensure gain knobs are turned up sufficiently.
  • 確認ample rates are synchronized between the OctoPre Dynamic, your audio interface, and your DAW.
  • Check routing settings in your audio interface's control software.
• 歪んだオーディオ:
  • Reduce input gain to prevent clipping (indicated by O/L LEDs).
  • Engage PAD switches for very hot signals.
  • ケーブルに欠陥がないか確認してください。
• 同期の問題:
  • Ensure the OctoPre Dynamic is correctly slaved to your main audio interface via ADAT or Word Clock.
  • Verify Word Clock settings if external synchronization is used.
