4. Setup Instructions
Follow these steps to set up your PROZOR eARC/ARC Audio Converter:
- Connect the Converter to your TV: Use the provided HDMI cable to connect the HDMI ARC input port on the converter to the eARC/ARC HDMI port on your television. Ensure you are using an HDMI 2.0/2.1 cable for eARC support.

TV PCM Settings Examples

- LG TV: Settings > General > External Devices > HDMI Settings > SIMPLINK (HDMI-CEC) > ACTIVE. For PCM: Sound > Advanced Settings > Digital Sound Output > PCM.
- Samsung TV: Settings > System > Expert Settings > Anynet+ (HDMI-CEC) > ACTIVE. For PCM: Sound > Expert Settings > Digital Output Audio Format > PCM.

5. Operating Instructions
Once set up, the converter operates automatically.
5.1 Audio Playback
Audio from your TV's eARC/ARC port will be extracted and output through the 3.5mm jack to your connected audio device.
5.2 CEC Volume Control
With supported devices, you can control the volume of the connected audio equipment directly using your TV's remote control via the CEC function (e.g., Anynet+, SimpLink). This eliminates the need for additional remotes. The functionality and display (e.g., volume bar) depend on your TV's CEC protocol support and specific settings.

5.3 High-Quality PCM Stereo Output
The converter provides two-channel PCM stereo with a sampling rate up to 192 kHz, ensuring clear, stable, and distortion-free sound to all analog audio devices.

6. Troubleshooting
If you encounter issues, please check the following common problems and solutions:
- No Sound:
- Ensure the converter is connected to the eARC/ARC HDMI port on your TV, not a standard HDMI port.
- Verify that the TV's audio output format is set to PCM. Multichannel formats like Dolby/DTS are not supported. Refer to the 'Configure TV Audio Settings' section for guidance.
- Check all cable connections (HDMI, USB power, 3.5mm audio) are secure.
- Ensure the USB power supply is stable. A separate USB power adapter is recommended.
- Volume Control Issues:
- Confirm that the CEC function (e.g., Anynet+, SimpLink) is enabled in your TV's settings.
- Ensure your connected audio device supports CEC volume control.
- Distorted Sound:
- Check that the TV's audio output is set to PCM.
- Ensure all cables are properly connected and not damaged.
- Test with different audio sources or devices to isolate the problem.
