5.2 eARC/ARC Connection

To use the eARC/ARC feature, follow these steps:

1. Ensure your TV supports ARC/eARC functions.
2. Connect your TV's HDMI ARC/eARC port to the HDMI OUT / ARC IN port on the extractor using an HDMI cable that supports ARC/eARC.
3. Set the DIP switch on the extractor to the "TV" mode (eARC ON/OFF switch to ON).
4. Enable CEC (Consumer Electronics Control) on your TV settings.
5. Connect your external speakers (e.g., soundbar, amplifier) to the desired audio output port on the extractor.

Note: Volume adjustment may not be controllable through the TV remote when using eARC/ARC with this extractor.

6. Operating Modes

The extractor features three audio output modes, selectable via the Audio Mode Switch:

1. PASS Mode:
   • Automatically mirrors your TV's native audio format.
   • Optical output supports all multi-channel formats.
   • Note: Analog R/L & AUX ports support 2.0 PCM only. Non-PCM inputs will result in digital buzz or noise on these analog outputs.
2. R/L Mode (2.1CH):
   • Universally downmixes all audio formats (PCM, Dolby Digital, Dolby TrueHD, DTS-HD) into standard 2.0 PCM stereo.
   • Delivers synchronized stereo sound across R/L, AUX, and Optical ports simultaneously.
3. SPDIF Mode (5.1CH):
   • Dedicated multi-channel surround sound mode.
   • Optical output supports all premium bitstream audio formats.
   • Note: Analog R/L & AUX ports require PCM input to function in this mode. Other formats will result in a static hum on these analog outputs.

7. High Resolution Support

This extractor supports high-definition video resolutions to ensure a clear visual experience:

• Supports up to 8K@60Hz and 4K@120Hz.
• Backward compatible with 4K@60Hz, 4K@30Hz, 2K@120Hz, and 1080P.
• Supports 24-bit, 30-bit, and 36-bit color.
• For optimal 8K@60Hz resolution, ensure your source device, display, and HDMI cables all support 8K60Hz.

8. Compatibility

The avedio links HDMI Audio Extractor is compatible with a wide range of devices:

• HDMI Input Devices: Blu-ray/DVD players, TV boxes, Fire TV Stick, Apple TV, PS3/4/5, Xbox, PC, laptops, Nintendo Switch, and more.
• HDMI Output Displays: Monitors, HD TVs, Projectors.
• Audio Output Devices: Amplifiers, AV receivers, Headphones, Speakers, Soundbars.

9. Troubleshooting

• No Audio Output from Analog Ports (RCA L/R, 3.5mm AUX): Ensure the audio mode is set to R/L for universal stereo downmixing, or that the input audio is PCM if in SPDIF mode. Non-PCM inputs will cause noise or hum in PASS or SPDIF modes on analog outputs.
• No Video or Audio: Verify all HDMI cables are securely connected. Ensure the extractor is powered via the 5V Type-C cable. Check that your source, display, and cables support the desired resolution and audio format.
• eARC/ARC Not Working: Confirm your TV's HDMI port supports ARC/eARC. Enable CEC on your TV. Use an HDMI cable that supports ARC/eARC. Ensure the ARC/eARC switch on the extractor is set to ON.
• Connecting TV as Signal Source Directly to HDMI IN: Do not connect a TV directly to the HDMI IN port as a signal source; this device is designed to extract audio from an HDMI source device (e.g., Blu-ray player, game console) before it reaches the TV.
• Intermittent Audio/Video: Check for loose connections. Try different HDMI cables. Ensure the power supply is stable.
