4. Setup and Installation
Follow these steps to set up your PROZOR Digital to Analog Audio Converter:
- Connect Digital Audio Source: Connect your digital audio source (e.g., TV, Blu-ray DVD, Game Console) to the converter's Optical (TOSLINK) or Coaxial input port using the appropriate cable.
- Connect Analog Audio Output:
- For stereo speakers or an amplifier, connect the L/R RCA output ports of the converter to your audio receiver or speakers using RCA cables.
- For headphones, connect your 3.5mm headphones to the 3.5mm jack output port on the converter.
- Power Connection: Connect the supplied USB power cable to the DC 5V input port on the converter. Plug the other end of the USB cable into a 5V USB power adapter (not included) or a USB port on your TV/device. Ensure a stable 5V 1A power supply to avoid noise.
- Configure Audio Output on Source Device: It is crucial to set your TV or source device's audio output format to PCM/LPCM for optimal compatibility and sound decoding.
Typical path for TV audio settings: Device main page → System Settings → Image and Sound → Sound Settings → Digital Audio Output → PCM/LPCM.

5. Operation
Once all connections are made and your source device is configured, the converter will automatically detect and decode the digital audio signal. The power indicator light on the converter will illuminate when it receives 5V power.
- Volume Adjustment: Use the volume control knob on the front of the converter to adjust the output volume for both the 3.5mm headphone jack and the L/R RCA outputs. Rotate clockwise to increase volume and counter-clockwise to decrease.
- Audio Mode Support: The converter supports DTS, Dolby AC-3, LPCM, PCM, and RAW audio modes. It can decode Dolby/DTS 5.1CH digital audio into 2.0CH analog audio output.

6. Troubleshooting
If you encounter issues with your PROZOR Digital to Analog Audio Converter, please refer to the following common troubleshooting steps:
- No Sound or Distorted Sound:
- Ensure all cables (optical/coaxial, RCA/3.5mm, power) are securely connected.
- Verify that your source device's digital audio output is set to PCM/LPCM format. This is a common cause for no sound or static.
- Check the volume level on both the converter and your connected audio device (headphones/speakers).
- Try a different optical or coaxial cable to rule out cable issues.
- Ensure the power indicator light on the converter is on.
- Humming Noise:
- Ensure the converter is powered by a stable 5V 1A power source. Using a low-quality or insufficient power supply can introduce noise.
- Try plugging the USB power cable into a different USB port or a dedicated USB wall adapter. Some USB 2.0 ports on older PCs might introduce hum.
- Check for ground loop issues. Try plugging all audio equipment into the same power strip.
- No Dolby/DTS Output:
- While the converter supports decoding Dolby AC-3 and DTS 5.1CH to 2.0CH analog, ensure your source device is actually outputting these formats.
- Confirm that the source content itself contains Dolby/DTS audio.
- Intermittent Audio:
- Check for loose connections.
- Ensure the optical cable's protective caps are removed before insertion and that the cable is not bent sharply.
