5. Setup Instructions
Follow these steps for easy installation and operation:
- Connect HDMI ARC Cable: Connect one end of the provided HDMI ARC cable to the 'ARC' port on the converter. Connect the other end to the 'HDMI ARC' port on your TV. Ensure the TV port is explicitly marked 'ARC'.
- Connect Audio Output: Use the provided 3.5mm to RCA audio cable. Connect the 3.5mm end to the converter's '3.5mm/RCA' output port. Connect the RCA ends (red and white) to the corresponding audio input ports on your headphones or sound system.
- Power Connection: Connect the Type-C cable to the converter's 'DC 5V' port. Connect the other end of the Type-C cable to a USB power source, such as a USB port on your TV or a standard 5V USB power adapter (not included).
- Configure TV Audio Settings: This is a crucial step to ensure proper functionality. You must set your TV's audio output format to PCM (Pulse Code Modulation).
Example TV PCM Setting Methods:
- Samsung TV:
- PCM format: Settings > Sound > Expert Settings > Audio Format > PCM
- External Sound System: Settings > Sound > Select Speaker > HDMI ARC
- LG TV:
- PCM setting method: Menu > All Settings > Sound Out > Optical > Digital Sound Out > PCM
- If you need to synchronize the audio output from the TV Sound System: Menu > All Settings > Sound Out > HDMI ARC
6. Operating Instructions
Once all connections are made and your TV's audio settings are configured to PCM, the CAMWAY ARC Audio Converter will automatically begin extracting audio from your TV's HDMI ARC port and outputting it to your connected audio device.
- Volume Control: The HDMI ARC mode supports volume control directly from your TV remote. To enable this, ensure the CEC (Consumer Electronics Control) volume control function is turned on in your TV's settings. The exact name for this function may vary by TV brand. When adjusting the volume, your TV will typically display a volume bar or +/- indicators.
7. Troubleshooting
If you encounter issues, please refer to the following troubleshooting tips:
- No Sound / Device Not Working:
- Check TV Port: Verify that your TV has an 'HDMI ARC' port, not a standard 'HDMI' or 'HDMI eARC' port. The converter is only compatible with HDMI ARC.
- TV Audio Settings: Ensure your TV's audio output format is set to PCM. Refer to Section 5 for specific TV brand instructions.
- Cable Connections: Double-check that all HDMI, 3.5mm/RCA, and Type-C power cables are securely connected to their respective ports on both the converter and your devices.
- Power Supply: Confirm the converter is receiving power via the Type-C cable. The Type-C cable is included, but a USB power adapter is not.
- No 5.1 Audio Output: This device is designed to output PCM/LPCM 2.0CH stereo audio only and does not support 5.1 channel audio formats like Dolby AC3. If your TV is outputting 5.1 audio, the converter will not process it correctly.
- Volume Control Issues: If you cannot control the volume via your TV remote, check your TV settings to ensure the CEC (Consumer Electronics Control) volume control function is enabled. The name of this setting may vary by TV manufacturer.
