• Three Audio Output Modes:
  • PASS Mode: Audio passes through to the HDMI output (TV/Projector). Only the TV will have sound.
  • 2CH Mode: 3.5mm audio output supports 2CH PCM LPCM stereo audio. Optical SPDIF output supports 2CH PCM. Both 3.5mm and optical audio outputs will have sound.
  • 5.1CH Mode: Optical SPDIF output supports 5.1CH Dolby Digital, Dolby TrueHD, DTS-HD. The source audio must be 5.1CH. Both 3.5mm and optical audio outputs will have sound.

4. Setup Instructions

Follow these steps to connect your avedio links HDMI Audio Extractor Converter:

1. Power Connection: Connect the provided DC 5V power adapter to the converter's DC 5V port and then plug it into a power outlet.
2. HDMI Input: Connect your HDMI source device (e.g., Blu-ray player, game console, TV box, laptop) to the "HDMI IN" port on the converter using an HDMI cable.
3. HDMI Output (Video): Connect your display device (e.g., TV, monitor, projector) to the "eARC/ARC HDMI OUT" port on the converter using an HDMI cable. This port carries both video and, if ARC/eARC is not used, audio to the display.
4. Audio Output (External Audio System):
   • For optical audio, connect an optical cable from the "SPDIF OUT" port on the converter to your soundbar or amplifier.
   • For stereo audio, connect the 3.5mm to 2 RCA audio cable from the "AUDIO OUT (3.5mm)" port on the converter to your amplifier or headphones.
5. ARC/eARC Setup (if applicable): If you intend to use the ARC/eARC function to send audio from your TV back to an external sound system:
   1. Connect your TV's HDMI ARC/eARC port to the converter's "eARC/ARC HDMI OUT" port.
   2. Connect the audio extractor's optical or 3.5mm output to your speaker or amplifier.
   3. In your TV settings, select ARC/eARC as the audio output.
   4. Ensure the ARC/eARC function is enabled on the audio extractor (if there's a dedicated switch, refer to the device itself).

   Note: Once ARC/eARC is enabled, your TV remote may lose its ability to control the volume of the external sound system. Volume adjustment will then be solely through the speaker/soundbar's controls.

5. Operating Instructions

The converter features a mode switch to select the desired audio output format. Locate the switch on the device and select one of the following modes:

• PASS Mode: In this mode, the audio from the HDMI input is passed directly to the HDMI output. Only your connected TV or projector will produce sound. This mode is suitable when you want to use your display's built-in speakers or when your display is connected to an external audio system.
• 2CH Mode: Select this mode for stereo audio output. The 3.5mm AUX jack will output 2-channel PCM/LPCM stereo audio, and the optical SPDIF port will also output 2-channel PCM audio. This mode is ideal for connecting to stereo sound systems, headphones, or soundbars that support 2-channel audio.
• 5.1CH Mode: Choose this mode for multi-channel audio output via the optical SPDIF port. It supports 5.1 channel Dolby Digital, Dolby TrueHD, and DTS-HD. Ensure your audio source is configured to output 5.1 channel audio and your connected sound system supports these formats. The 3.5mm AUX output will also be active, providing stereo downmix if available.

To ensure proper audio output, always verify that your source device's audio settings (e.g., Blu-ray player, game console) are configured to match the selected mode on the converter and the capabilities of your audio receiving device.

7. Troubleshooting

If you encounter issues with your avedio links HDMI Audio Extractor Converter, refer to the following common problems and solutions:

7.1 No sound from the Optical output port

1. Verify that your audio receiving device (soundbar, amplifier) is correctly adjusted to play optical audio and is set to the correct input channel.
2. Adjust the audio format on your source device. Optical fiber typically supports 5.1 channels, but some devices may require specific settings.
3. If your TV or speaker does not support the current audio format, change the input source audio format to PCM or LPCM.
4. For 4K resolution, ensure the total length of the HDMI cable (before and after the switch) does not exceed 3 meters (9.8 ft).
5. Confirm that the audio format on the input source device is set to Stereo, DTS, or standard Dolby Digital. Note: Dolby Digital Plus is not supported.

7.2 No sound from the L/R (3.5mm AUX) output port

1. Ensure your audio receiving device (amplifier, headphones) is correctly adjusted to play analog audio and is set to the correct input channel.
2. Adjust the audio format on your source device. The 3.5mm output typically supports 2.0CH stereo audio.
3. If your TV or speaker does not support the current audio format, change the input source audio format to PCM or LPCM.
4. For 4K resolution, ensure the total length of the HDMI cable (before and after the switch) does not exceed 3 meters (9.8 ft).
5. Confirm that the audio format on the input source device is set to Stereo.

Figure 17: Troubleshooting steps for resolving issues with 3.5mm analog audio output.

General Note for Audio Output: To receive audio from both Optical and L/R output ports simultaneously, the input source device format must be set to PCM/stereo.
