• 10MHz Sine Wave Output: Two outputs for connecting to compatible audio devices.
• 10MHz Square Wave Output: Two outputs for connecting to compatible audio devices.
• DC電源入力（12V）： 外部DC電源用。
• AC Input (100-240V AC): For standard AC power connection.
• 電源スイッチ： デバイスの電源をオンまたはオフにします。

2.3 主な特徴

• Custom SC-cut OCXO: A high-quality, custom-designed Oven Controlled Crystal Oscillator for precise clock signals.
• Dual Waveform Outputs: Provides two sine wave and two square wave 10MHz outputs simultaneously.
• 独立電源: Features a low-noise, high-current LDO exclusively for the OCXO, with dedicated shielding for isolation.
• Synchronized Isolated Output: All four outputs maintain phase synchronization of less than 0.00001° while being isolated.
• Wide Frequency Domain & Low Jitter: Jitter is below 200 fs (BW 1 Hz ~ 1 MHz), ensuring precise reference clock signals.
• AC+DC Dual Input: Supports worldwide 110-230V AC and 12V DC input, with DC priority.
• Vivid UI: Full-color display monitoring core chamber temperature in real-time (red for warm-up, yellow for operational, green for optimal).
• Cascade Symmetric Low-Noise Power Design: Stage-by-stagボリュームtage regulation for optimal power delivery.

3. セットアップ手順

3.1電源接続

1. 背面パネルの電源スイッチがオフになっていることを確認します。
2. Connect the provided AC power cable to the AC input port (100-240V AC) on the rear panel and then to a suitable power outlet. Alternatively, for DC power, connect a 12V DC power supply to the DC power input port. The device prioritizes DC input if both are connected.
3. Flip the power switch to the ON position. The display will illuminate.

3.2 オーディオデバイスへの接続

The SC1 EVO provides two 10MHz sine wave outputs and two 10MHz square wave outputs. Use high-quality 75Ω coaxial cables to connect the appropriate output ports on the SC1 EVO to the 10MHz clock input ports on your compatible audio devices (e.g., DACs, streamers, CD players).

1. Identify the required clock input type (sine wave or square wave) on your audio device.
2. Connect one end of a 75Ω coaxial cable to the corresponding 10MHz output port on the SC1 EVO.
3. Connect the other end of the coaxial cable to the 10MHz clock input on your audio device.
4. Repeat for additional devices as needed. All four outputs can be used simultaneously.

4.1ディスプレイインターフェース

画像の説明: The Aune SC1 EVO's full-color display showing the 10MHz frequency and real-time core chamber temperature. The display changes color (red, yellow, green) to indicate the clock's status from warm-up to optimal operation.

The SC1 EVO features a full-color display that provides real-time information about the clock's status. It monitors the core chamber temperature, indicating:

• 赤： Warm-up phase.
• 黄： Operational, but not yet at peak stability.
• 緑： Optimal operating temperature and stability achieved.

The display will also show the 10MHz frequency output.

4.2 Output Selection and Usage

The SC1 EVO automatically outputs both sine wave and square wave 10MHz signals simultaneously from their respective ports once powered on. There is no manual selection required for the output type. Ensure your connected audio device is configured to receive the external 10MHz clock signal.

6. メンテナンス

6.1 クリーニング

• 掃除する前に必ず電源を切ってください。
• デバイスの外側を拭くときは、柔らかく乾いた糸くずの出ない布を使用してください。
• 液体クリーナー、エアゾール、溶剤は、仕上げや内部コンポーネントを損傷する恐れがあるため、使用しないでください。

6.2 環境への配慮

• デバイスを安定した水平な面に置きます。
• Avoid exposing the device to direct sunlight, excessive heat, humidity, or dust.
• 過熱を防ぐために、ユニットの周囲に十分な換気を確保してください。

7。 トラブルシューティング

If you encounter issues with your Aune SC1 EVO, please refer to the following common problems and solutions:

• 電源なし:
  • 電源ケーブルがデバイスと電源コンセントの両方にしっかりと接続されているかどうかを確認します。
  • 背面パネルの電源スイッチがオンの位置になっていることを確認します。
  • 電源コンセントが機能していることを確認します。
• No Clock Signal Output:
  • Confirm that the SC1 EVO is powered on and the display shows an operational status (yellow or green).
  • Check the coaxial cable connections between the SC1 EVO and your audio device. Ensure they are secure and the cables are not damaged.
  • Verify that your audio device is correctly configured to accept an external 10MHz clock signal and is connected to the appropriate input type (sine or square wave).
• 表示の問題:
  • If the display is dim or flickering, try restarting the device.
  • If the display shows an unexpected color (e.g., red for an extended period after warm-up), ensure the device has adequate ventilation and is not in an excessively hot environment.
