Setup Instructions

1. Connect the Optical Cable: Plug the optical cable from your source device (e.g., TV, Blu-ray player, gaming console) into the optical input port of the eSynic DAC converter.
2. Connect the 3.5mm Audio Cable: Connect the 3.5mm audio output from the converter to your headphones or speakers.
3. Provide Power: Connect the USB power cable to the converter and then to a 5V/1A USB power adapter (not included) or a USB port on your TV/device.
4. Configure Source Device Audio Output: This converter supports PCM 2.0 audio format ONLY. It is not compatible with Dolby/DTS 5.1/7.1 channel signals. You must set your source device's digital audio output to PCM mode. For most TVs (Samsung/LG/Sony), navigate to: Settings → Sound → Digital Audio Output → PCM. This step is crucial for proper functionality and to avoid 'no sound' issues.

2. Adjust Volume: Use the built-in volume control knob on the converter to adjust the output volume to your headphones or speakers. Note that the TV remote will not control the volume of the output from the converter.
3. Enjoy Audio: Experience clear, amplified 192KHz/24bit audio from your connected analog devices.

Troubleshooting

• No Sound:
  • Ensure all cables are securely connected.
  • Verify that your TV's digital audio output is set to PCM mode (not Dolby/DTS). Refer to your TV's sound settings.
  • Check if the converter is receiving power from the USB cable.
• Noise/Crackling Sound:
  • Ensure all connections are firm.
  • Try a different USB power source (e.g., a dedicated 5V/1A wall adapter instead of a TV USB port).
• Low Sound:
  • Adjust the volume knob on the converter.
  • If using high-impedance headphones, an additional headphone amplifier may be required.
• Not working with streaming apps (YouTube, Netflix, etc.):
  • Many streaming services output Dolby Digital 5.1 audio, which this converter does not support. Ensure your TV's audio output is set to PCM 2.0.
