4. Installation and Setup
Follow these steps to set up your CAMWAY eARC Audio Extractor:
- Connect to TV: Use the included HDMI cable to connect the 'eARC IN' port on the extractor to the HDMI ARC or eARC port on your television. Ensure your TV's HDMI port supports ARC/eARC.
- Activate TV Settings: Access your TV's settings menu and activate the CEC (Consumer Electronics Control) function. This is often required for ARC/eARC functionality.
- Set TV Audio Output: In your TV's audio settings, configure the audio output to 'HDMI ARC/eARC'. For 5.1 channel optical output, ensure the TV's audio format is set to 'Bitstream' or 'Auto'. For RCA/3.5mm stereo output, set the TV's audio format to 'PCM'.
- Connect Audio Devices: Connect your desired audio output devices (soundbar, amplifier, headphones) to the corresponding ports on the extractor (Optical, RCA, or 3.5mm). You can use multiple outputs simultaneously.
- Power On: Connect the included USB power cable to the 'DC5V PWR' port on the extractor and plug the other end into a USB power source (e.g., a TV USB port or a 5V/1A USB power adapter). Turn on the extractor using the ON/OFF switch.
Important Note: For stable operation, especially when using RCA or 3.5mm outputs or if your audio system does not support Bitstream, it is recommended to use an independent USB power adapter for power supply to avoid issues caused by unstable power from the TV's USB port.
5. Operating Instructions
Once connected and powered on, the CAMWAY eARC Audio Extractor operates automatically based on your TV's audio output settings.
- Audio Format Indicators: Observe the 2.0CH and 5.1CH indicators on the device. The illuminated indicator will show the current audio format being outputted.
- 5.1 Channel Output: If your TV is eARC compatible and its audio output is set to 'Bitstream' or 'Auto', the 5.1CH indicator will light up, and 5.1 surround sound will be available via the optical output. Ensure your connected audio receiver or soundbar supports 5.1 channel decoding.
- 2.0 Channel Output: If your TV's audio output is set to 'PCM', the 2.0CH indicator will light up, and stereo audio will be available via the optical, RCA, and 3.5mm outputs.
- Simultaneous Output: The device can output audio to all connected outputs (Optical, RCA, 3.5mm) simultaneously, allowing you to use multiple audio systems at once.
