6. Operating Instructions

6.1 Audio EDID Settings

The AUDIO CHANNEL SWITCH on the front panel allows you to select the desired audio output mode:

• PASS Mode: In this mode, the audio EDID (Extended Display Identification Data) is automatically detected from the connected display device (TV). The audio output will match the capabilities of your display.
• 2.0CH Mode: This mode forces the audio output to 2.0 channel PCM/LPCM stereo audio. This is suitable for 3.5mm stereo output and for SPDIF output when connecting to a stereo audio system.
• 5.1CH Mode: This mode enables 5.1 channel audio output via the SPDIF port, supporting formats such as Dolby Digital, Dolby TrueHD, DTS-HD, and DTS. This mode is ideal for connecting to a 5.1 channel AV receiver or soundbar. The 3.5mm output will not produce 5.1 channel audio.

6.2 ARC (Audio Return Channel) Function

The ARC function allows audio from your TV's built-in tuner or smart apps to be sent back to your audio system via the HDMI cable. To use ARC:

1. Ensure your TV's HDMI port supports ARC and that the ARC function is enabled in your TV's settings.
2. Connect the HDMI OUT port of the converter to the ARC-enabled HDMI input on your TV.
3. Set the ARC switch on the rear panel of the converter to the ON position. The ARC LED on the front panel will illuminate.
4. Connect your audio system to the SPDIF output of the converter.
5. The audio from your TV will now be routed through the converter's SPDIF output to your audio system.

Note: The 3.5mm stereo output does not support ARC audio. ARC audio is only available via the SPDIF output.

7. Troubleshooting

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

• No Picture or Flickering Picture:
  • Ensure all HDMI cables are securely connected.
  • Try using different HDMI cables, as faulty cables can cause issues.
  • Verify that the power adapter is correctly connected and the POWER LED is on.
  • Test the HDMI source and display directly without the converter to rule out issues with those devices.
  • Ensure your display supports the resolution and refresh rate output by your source device.
• No Audio Output:
  • Check all audio cable connections (optical, 3.5mm).
  • Verify that your audio system is powered on and set to the correct input.
  • Adjust the AUDIO CHANNEL SWITCH on the converter. Try "2.0CH" mode for stereo audio or "5.1CH" for surround sound via SPDIF.
  • Ensure the audio format from your HDMI source is compatible with the selected audio mode and your audio system. For example, some older sound systems may not support certain Dolby/DTS formats.
  • If using ARC, ensure the ARC switch is ON and your TV's ARC function is enabled and connected to the correct HDMI port. Remember, ARC audio is only via SPDIF.
  • Check the volume levels on your audio system and HDMI source.
• ARC Function Not Working:
  • Confirm your TV's HDMI port is ARC-enabled and the ARC feature is activated in your TV's settings.
  • Ensure the HDMI cable is connected from the converter's HDMI OUT to the TV's ARC-enabled HDMI IN.
  • Toggle the ARC switch on the converter to ensure it's engaged.
  • Only the SPDIF output supports ARC audio.
