- Connect Display: Use an HDMI cable to connect your display device (e.g., TV, monitor) to the HDMI OUT port on the extractor.
- Connect Audio Output: Choose one or more audio output options based on your setup:
- For optical digital audio, connect an optical cable from the SPDIF port to your soundbar or amplifier.
- For analog RCA audio, connect RCA cables from the RCA Audio Out (R/L) ports to your amplifier or speakers.
- For headphones, connect a 3.5mm audio cable from the 3.5mm Audio Out port to your headphones.
- Select Audio Mode: Use the PASS/R/L/SPDIF switch to select the appropriate audio output mode (refer to Section 6 for details).

6. Operating Modes
The device offers three audio output modes, selectable via the switch on the unit:
- PASS Mode: In this mode, audio is output only from the TV itself. The extractor passes the audio signal directly to the HDMI OUT port without processing or splitting it to the dedicated audio outputs.
- R/L Mode: This mode provides 2-channel (stereo) audio output via the RCA and 3.5mm jacks. It is compatible with LPCM audio formats. Use this mode for stereo sound systems or headphones.
- SPDIF Mode: This mode enables 5.1-channel optical digital audio output via the SPDIF port. It supports Dolby and DTS audio formats. Use this mode for surround sound systems that accept optical digital input.

7. Troubleshooting
If you encounter issues, please refer to the following points:
- Power Adapter: Always use the included 5V1A power adapter. This product does not support fast charging.
- Volume Control: This product does not have a built-in audio amplification chip. If the volume is low, manually adjust the volume on your connected speakers or headphones. This is not a product defect.
- Video/Audio Issues (Black Screen, Flickering, No Sound): We recommend using a high-quality 32AWG HDMI 2.1 compliant cable. Using low-quality cables may result in a black screen, screen flickering, or loss of audio.
- ARC/eARC and CEC: Ensure your TV's HDMI port is ARC/eARC compatible and that CEC functionality is enabled in your TV's settings. Some devices may not fully support CEC functionality.
- No Sound/Noise with Non-Compatible Devices: If connecting to a non-compatible device results in no sound or noise, please set your TV's audio output to "PCM".
