- For 3.5mm Headphone Output: Connect headphones or a 3.5mm audio cable to the 3.5mm jack output port.
4.2 TV Audio Output Settings (Important)
For optimal performance and to avoid compatibility issues, ensure your TV's digital audio output is set to PCM/LPCM format. This converter does not support 5.1 channel audio formats like Dolby and DTS.
Typical path to adjust TV audio settings:
Device Homepage → System Settings → Image and Sound → Sound Settings → Digital Audio Output → PCM

5.2 Bluetooth Pairing and Playback
The converter includes an integrated Bluetooth 5.0 receiver for wireless audio streaming.
- Ensure the DAC converter is powered on.
- On your mobile device (smartphone, tablet, etc.), enable Bluetooth and search for available devices.
- Select "PROZOR RX5.0" (or similar name) from the list of available devices to pair.
- Once paired, the converter will automatically switch to Bluetooth playback mode, and you can stream audio wirelessly.

6. Troubleshooting
- No Sound Output:
- Ensure all cables are securely connected.
- Verify the DAC converter is powered on.
- Check your source device's audio output settings. For optical/coaxial input, the source device's digital audio output must be set to PCM/LPCM. This converter does not support Dolby or DTS 5.1 channel audio.
- Adjust the volume knob on the DAC converter and your receiving audio device (amplifier, headphones).
- Bluetooth Connection Issues:
- Ensure Bluetooth is enabled on your mobile device and the converter is discoverable.
- If your phone automatically connects to the converter, but you are using an optical/coaxial input, disconnect the Bluetooth connection on your phone. Bluetooth input takes priority.
- Move your device closer to the converter to ensure it's within the Bluetooth range (up to 50 feet indoors).
- Audio Delay/Synchronization Issues:
- While the device is designed for minimal delay, ensure your source device's audio settings do not introduce additional processing that could cause latency.
