6. Operating Instructions

6.1 EDID Audio Output Settings

The EDID switch allows you to control the audio format presented to the source device, ensuring optimal compatibility with your audio system. Select the appropriate mode based on your soundbar or receiver capabilities:

This image details the EDID switch settings (FIXED 4K7.1, SPDIF5.1, ATMOS) and their corresponding video and audio output behaviors, including a note about not being able to use Dolby Atmos and SPDIF outputs simultaneously.

• FIXED 4K7.1:
  • Video: 4K@120Hz VRR.
  • Audio: Atmos/7.1CH.
  • Best for: Dolby Atmos soundbars/home theater systems.
• SPDIF5.1:
  • Video: Copies TV's EDID.
  • Audio: 5.1CH.
  • Best for: Optical-compatible receivers/older sound systems.
• ATMOS:
  • Video: Copies TV's EDID.
  • Audio: Atmos/7.1CH.
  • Best for: Dolby Atmos soundbars/home theater systems.

Important Note: You cannot use Dolby Atmos and SPDIF outputs simultaneously. If 4K7.1/Dolby Atmos Mode is selected, SPDIF Output will have no signal (inactive). If SPDIF 5.1CH Mode is selected, HDMI OUT 2 & SPDIF will output 5.1 channel digital audio (Dolby Atmos disabled).

6.2 CEC Bypass Control

The extractor supports CEC (Consumer Electronics Control) bypass, allowing your TV remote's directional and confirm buttons to control menus on your source device (e.g., PS5 or Xbox user interface). This feature streamlines control without needing multiple remotes.

This image shows how the TV remote can control source device menus (e.g., PS5/Xbox UI) through the extractor's CEC bypass feature, noting that volume control is not supported.

Note: CEC Bypass does not support volume control. Volume adjustments must be made directly on your soundbar or audio receiver.

8. Troubleshooting

If you encounter issues with your ROFAVEZCO HDMI 2.1 eARC Audio Extractor, please refer to the following common solutions:

• No Power/Device Not Working:
  • Ensure you are using a 5V/2A power adapter (not included) and that it is properly connected to the POWER/FW port.
  • Try using a different power adapter and/or USB Type-C cable.
  • Unplug and replug the power cable to reset the device.
• No Video/Audio Output:
  • Verify all HDMI and audio cables are securely connected to the correct ports.
  • Ensure you are using high-quality HDMI 2.1 cables, especially for 4K@120Hz signals. Cables longer than 10ft (3m) are not recommended.
  • Check the EDID switch setting on the extractor. Adjust it to match the capabilities of your audio system (e.g., ATMOS for Dolby Atmos soundbars, SPDIF5.1 for optical 5.1CH).
  • Confirm that your TV/display and audio receiver/soundbar are set to the correct input sources.
  • Remember that Dolby Atmos and SPDIF outputs cannot be used simultaneously. If you need SPDIF, ensure the EDID is set to SPDIF5.1.
• Incompatibility Issues:
  • If you experience specific compatibility problems with certain devices, check the manufacturer's official website for potential firmware updates.
• No Volume Control via TV Remote:
  • The CEC Bypass feature allows menu navigation but does not support volume control. Adjust volume directly on your soundbar or audio receiver.
• Bright Blue Lights:
  • The device features bright indicator lights. If these are distracting, especially in dark environments, you may cover them with opaque tape.

If the problem persists after trying these steps, please contact customer support for further assistance.
