4. Setup Instructions

Follow these steps to connect and set up your Analog to Digital Audio Converter:

4.1 Power Connection

1. Connect the Micro Type B end of the provided USB power cable to the USB 5V Power Input port on the rear panel of the converter.
2. Connect the standard USB-A end of the power cable to a 5V USB power source (e.g., a USB wall adapter, TV USB port, or computer USB port). Ensure a stable power supply for optimal performance.

4.2 Audio Input Connection

Choose one of the following input methods based on your source device:

• Using RCA L/R: Connect your analog audio source (e.g., DVD player, TV) to the RCA L/R Audio Input jacks on the front panel using an RCA stereo audio cable. Match the red plug to the 'R' (right) jack and the white plug to the 'L' (left) jack.
• Using 3.5mm Jack: Connect your analog audio source (e.g., smartphone, laptop) to the AUX 3.5mm Jack Input on the front panel using a 3.5mm audio cable.

5. Operating Instructions

Once all connections are made and the converter is powered on, the device will automatically convert the analog audio input to digital optical and coaxial outputs. No additional configuration is typically required on the converter itself.

• Ensure your source device is playing audio.
• Set your receiving digital audio device (soundbar, amplifier) to the correct input source (Optical or Coaxial).
• The converter supports uncompressed 2-channel LPCM digital audio signal output.
• Output sampling rate is supported at 96KHz.

6. Troubleshooting

• No Audio Output:
  • Verify all cables are securely connected to their respective ports.
  • Ensure the converter is receiving sufficient and stable 5V power.
  • Check that your digital audio receiving device is set to the correct input (Optical or Coaxial).
  • Confirm that the analog audio source is playing and its volume is turned up.
  • Ensure the audio format from your source is compatible (PCM/LPCM). Some devices may require setting their audio output to PCM.
• Distorted Audio:
  • Check for loose cable connections.
  • Ensure the power supply is stable and not fluctuating.
  • Test with different audio cables if possible.
• Converter Not Powering On:
  • Verify the USB power cable is correctly connected to both the converter and the power source.
  • Try a different 5V USB power adapter or USB port.
