画像の説明: トップダウン view of the FiiO D3 (D03K) Digital to Analog Audio Converter. The device is black with gold-plated RCA output jacks (L and R) on one side, and coaxial and optical digital inputs on the other. A mini-USB power input is also visible. Status indicator lights for 'Power' and 'Locked' are present on the top surface.
画像の説明: 底 view of the FiiO D3 (D03K) Digital to Analog Audio Converter. The bottom panel shows the model number (D03K), manufacturing details, and an input selection switch to toggle between Coaxial and Optical inputs. The RCA output jacks are visible on one side.
設定
- 電源接続: Connect the provided AC power adapter to the DC 5V MINI USB port on the FiiO D3 (D03K). Plug the adapter into a power outlet.
- デジタルオーディオ入力:
- For Optical Input: Connect an optical Toslink cable from your digital audio source (e.g., TV, CD/DVD/Blu-Ray player, game console) to the "Optical In" port on the FiiO D3 (D03K).
- For Coaxial Input: Connect a coaxial digital audio cable from your digital audio source to the "Coaxial In" port on the FiiO D3 (D03K).
- 入力選択: Use the switch on the bottom of the FiiO D3 (D03K) to select either "Optical" or "Coaxial" input, matching your connected source.
- アナログ音声出力:
- Connect RCA audio cables (red for right, white for left) from the "L OUT" and "R OUT" ports on the FiiO D3 (D03K) to the corresponding analog audio input ports on your amplifier or self-powered speakers.
- Alternatively, for headphone or 2.1 audio systems, use the 3.5mm sound output dock.
- ソースデバイスの設定: Ensure your digital audio source device is configured to output audio in PCM (Pulse-Code Modulation) format. The FiiO D3 (D03K) supports PCM only. Refer to your source device's manual for specific audio output settings.
操作手順
- 電源オン: Once all connections are secure and the power adapter is plugged in, the "Power" indicator light on the FiiO D3 (D03K) will illuminate.
- Signal Lock: When a valid digital audio signal is received from your source, the "Locked" indicator light will illuminate, confirming a successful connection.
- オーディオ再生: Begin playing audio from your digital source. The FiiO D3 (D03K) will convert the digital signal to analog, which will then be output through your connected amplifierまたはスピーカー。
- 音量コントロール: 接続したデバイスを使用して音量を調整します amplifier or speakers. The FiiO D3 (D03K) does not have its own volume control.
トラブルシューティング
- サウンド出力なし:
- すべてのケーブルが正しい入力/出力ポートにしっかりと接続されていることを確認します。
- Ensure the FiiO D3 (D03K) is powered on (red "Power" light is on).
- Check that the "Locked" indicator light is illuminated, confirming a digital signal is being received.
- Confirm your source device's digital audio output is set to PCM format. The FiiO D3 (D03K) does not support DTS or Dolby Digital.
- Make sure the input selection switch on the bottom of the FiiO D3 (D03K) matches the connected digital input (Optical or Coaxial).
- Increase the volume on your connected amplifierまたはスピーカー。
- 音質が歪んでいる、または悪い:
- すべてのケーブルが良好な状態であり、正しく接続されていることを確認します。
- 接続の緩みやケーブルの損傷がないか確認してください。
- Verify that the power supply is stable and providing sufficient power (DC 5V).
- If connecting to a TV, ensure the TV's USB connection is 1Amp; anything less may lead to static noise.
