Solid State Logic PureDrive Octo 8チャンネルマイクプリアンプ ユーザーマニュアル

1. はじめに

The Solid State Logic PureDrive Octo is an 8-channel microphone preamplifier designed for professional audio recording and production environments. It integrates SSL's renowned PURE and DRIVE modes, offering versatile tonal characteristics, along with advanced digital connectivity and an onboard USB interface. This manual provides comprehensive instructions for the setup, operation, and maintenance of your PureDrive Octo unit.

The PureDrive Octo features four mic preamp input impedance options, allowing for exploration of various tonal possibilities and optimal matching with different microphone types. Each channel includes independent +48V phantom power, polarity inversion, and a High Pass Filter, making it a highly capable and feature-rich outboard microphone preamplifier。

2. 主な特徴

• 8 channel high-performance PureDrive mic preamps.
• +48V phantom power, polarity invert, and 3rd order hi-pass filter per channel.
• 31-step Trim control with precise 1 dB increments for signal level adjustment and gain staging。
• Line inputs via TRS Jack or dedicated D-Sub connectivity.
• Four mic preamp input impedance options to explore new tonal possibilities from dynamic and ribbon microphones.
• PURE and DRIVE modes, including a new 'Asymmetric' DRIVE option.
• Advanced digital connectivity (ADAT, AES/EBU).
• Onboard USB audio interface.

フロントパネル

This image displays the front panel of the PureDrive Octo. It features eight identical input channels, each with dedicated controls for Gain, Trim, and various processing options. On the right, digital metering and A/D conversion controls are visible.

背面パネル

The rear panel provides all input and output connections. This includes XLR/TRS combo jacks for microphone/line inputs, D-Sub connectors for line inputs and outputs/sends, ADAT and AES/EBU digital outputs, Wordclock I/O, and a USB port for computer connectivity. The power inlet is located on the far left.

4.セットアップガイド

4.1開梱と配置

• Carefully remove the PureDrive Octo from its packaging.
• Place the unit in a well-ventilated area, preferably in a standard 19-inch equipment rack. Ensure adequate airflow around the unit to prevent overheating.
• ユニットを熱源の近くや直射日光の当たる場所に置かないでください。

4.2電源接続

• ユニットの電源スイッチがオフになっていることを確認します。
• Connect the supplied AC power cable to the IEC inlet on the rear panel of the PureDrive Octo.
• Plug the other end of the power cable into a grounded AC outlet.

4.3オーディオ接続

• マイク入力： Connect microphones to the XLR inputs on the rear panel (Channels 1-8).
• ライン入力: Connect line-level sources using TRS jacks or the dedicated D-Sub connectors on the rear panel.
• デジタル出力： Connect the ADAT OUT ports to your audio interface or digital mixer for multi-channel digital audio. Use AES/EBU outputs for stereo digital audio.
• USB接続: Connect the USB port on the rear panel to your computer for use as an audio interface. Install necessary drivers if prompted by your operating system.
• ワードクロック: For synchronization with other digital audio devices, connect a Wordclock cable to the WORDCLOCK IN/OUT ports.

5. 操作手順

5.1 電源のオン/オフ

• To power on, flip the power switch on the rear panel to the ON position.
• 電源を切るには、電源スイッチを OFF の位置に切り替えます。

5.2 Channel Controls (Per Channel)

• ゲインノブ: Adjusts the input gain for the microphone preamplifier. Use this to set the primary signal level.
• TRIMノブ: Provides fine-tuning of the output level in 1 dB increments. This allows for precise level matching and can be used to drive the signal into the DRIVE circuit.
• +48Vボタン: Engages phantom power for condenser microphones. Ensure the microphone is connected before activating.
• POLARITY Button: Inverts the phase of the input signal. Useful for correcting phase issues when using multiple microphones.
• HPF Button: Activates a High Pass Filter to reduce unwanted low-frequency rumble or proximity effect.
• Z.D. (Impedance) Button: Cycles through four input impedance options. Experiment with different settings to find the optimal tonal response for your microphone.
• PURE/DRIVE Button: Toggles between the PURE and DRIVE preamp モード。
  • PURE Mode: Provides a clean, transparent, and linear amplification。
  • ドライブモード: Introduces harmonic saturation and warmth. The PureDrive Octo also features an 'Asymmetric' DRIVE option for unique tonal shaping.

5.3 A/D Conversion and Digital Output Controls

• レートノブ: sを選択しますample rate for the A/D converters (e.g., 44.1kHz, 48kHz, 88.2kHz, 96kHz).
• 時計ボタン: Selects the clock source (Internal, Wordclock, USB).
• メータリング： The front panel features LED meters for each channel, providing visual feedback on input levels.

6. メンテナンス

• クリーニング： 本体の外装を清掃する際は、柔らかく乾いた布をご使用ください。研磨剤入りの洗剤や溶剤は使用しないでください。
• 換気： 過熱を防ぐために通気口が塞がれていないことを確認してください。
• ストレージ： When not in use for extended periods, store the unit in a cool, dry environment, away from dust and extreme temperatures.

7。 トラブルシューティング

• 電源なし:
  • 電源ケーブルが本体とACコンセントの両方にしっかりと接続されているか確認してください。
  • 電源コンセントが機能していることを確認します。
• オーディオ出力なし:
  • すべてのオーディオ ケーブルが入力と出力に正しく接続されていることを確認します。
  • Check the GAIN and TRIM settings on the relevant channels.
  • Verify that the correct input source is selected on your receiving device (audio interface, mixer).
  • If using digital outputs (ADAT, AES/EBU, USB), ensure sample rates and clocking are correctly synchronized between devices.
• 歪んだオーディオ:
  • Reduce the GAIN or TRIM level to prevent clipping.
  • Check the input level of your microphone or line source.
  • Ensure the PURE/DRIVE mode is set as desired; DRIVE mode intentionally adds harmonic distortion.
