Setup Instructions
Follow these steps to connect and set up your PROZOR 192kHz Digital to Analog Audio Converter:
- Connect Digital Audio Source: Connect your digital audio source (e.g., TV, Blu-ray player, game console) to the converter's Toslink (optical) or Coaxial input using the appropriate cable. Ensure the cable is fully inserted.
- Connect Analog Audio Receiver: Connect your analog audio receiver (e.g., amplifier, headphones, speakers) to the converter's L/R RCA outputs or 3.5mm headphone jack.
- Power Connection: Connect the provided USB power cable to the DC 5V input on the converter. Plug the USB end into a standard 5V 1A USB power adapter (not included) or a compatible USB port on your source device (e.g., TV). The power indicator LED on the converter will illuminate when powered.
- Configure Audio Source: It is crucial to set your digital audio source's output format to PCM/LPCM. Refer to your source device's user manual for specific instructions on how to change this audio output setting. The converter does not support DTS/Dolby AC3 or other 5.1 channel audio formats.

Important Notes
- This converter is designed for digital to analog conversion only and is NOT reversible. It cannot convert analog signals to digital.
- A 5V 1A USB power adapter is required but not included. Using a power adapter with insufficient current may result in unstable operation or poor audio quality.
- For optimal performance, ensure your audio source's digital output is set to PCM/LPCM format. DTS/Dolby AC3 and other 5.1 channel audio formats are not supported by this device.
- The device supports audio sampling rates of 32kHz, 44.1kHz, 48kHz, 96kHz, and up to 192kHz at 24-bit resolution.
- The aluminum metal shell provides durability and helps with heat dissipation.

Troubleshooting
No Sound Output
- Verify all audio and power cables are securely connected to the correct ports.
- Ensure the power indicator LED on the converter is illuminated. If not, check the USB power connection and adapter.
- Confirm that your digital audio source's output format is set to PCM/LPCM. This is a common cause for no sound.
- Adjust the volume knob on the converter and the volume on your connected analog audio device (e.g., headphones, amplifier).
- Test with different audio cables or a different digital audio source to help isolate whether the issue is with the converter, cables, or source device.
Buzzing or Static Noise
- Ensure all connections are tight and free from interference.
- Try using a different 5V 1A USB power adapter. A low-quality or underpowered adapter can introduce noise.
- Check for ground loop issues. Try plugging the power adapter into a different electrical outlet or using a ground loop isolator if the issue persists.
- Confirm the input audio format is PCM/LPCM. Incorrect formats can sometimes cause unexpected audio artifacts.
