Step-by-Step Connection
- Connect HDMI Source: Use an HDMI cable to connect your HDMI source device (e.g., PS5, Blu-ray player, Roku) to the HDMI IN port on the extractor.
- Connect HDMI Display: Use another HDMI cable to connect your HDMI display (e.g., TV, monitor, projector) to the HDMI OUT port on the extractor.
- Connect Audio Output: Choose your desired audio output and connect it to your audio receiver, soundbar, speakers, or headphones:
- For 5.1 channel audio (Dolby DTS 5.1), connect an optical cable to the Optical port or a coaxial cable to the Coaxial port.
- For 2.0 channel stereo audio (PCM2.0), connect RCA cables to the L/R ports or a 3.5mm audio cable to the AUX port.
- Connect Power: Connect the provided Micro USB power cable to the USB 5V port on the extractor. Connect the other end to a USB power source (e.g., a USB port on your TV, a USB wall adapter, or a power bank). While many source devices provide sufficient power, external power may be required for stable operation.

Operating Instructions
EDID Management
The HDMI Audio Extractor features an EDID (Extended Display Identification Data) management switch, allowing you to configure the audio and video output behavior. Use the red DIP switch on the unit to select one of the 8 available modes.

Each switch position (1, 2, 3) can be set to ON or OFF to achieve different configurations. Refer to the table above to select the appropriate mode for your setup. For example:
- To copy display resolution and output 2CH PCM audio on all outputs, set switches to a specific configuration (e.g., 1-OFF, 2-OFF, 3-OFF).
- To force 4K resolution and output Dolby DTS 5.1CH on Optical/Coaxial, set switches accordingly.
Audio Sync and TV Mute Functionality

- Audio Sync: In 2-channel mode, the device ensures synchronized audio output across all enabled audio ports (AUX, L/R, Coaxial, Optical, HDMI).
- HDMI Out TV Mute: When audio is extracted to external speakers via the extractor's audio outputs, the HDMI output to the TV can be configured to mute its audio, preventing duplicate sound. This is managed through the EDID settings.
Maintenance
To ensure the longevity and optimal performance of your VEDINDUST HDMI Audio Extractor, follow these maintenance guidelines:
- Cleaning: Use a soft, dry cloth to clean the unit. Avoid using liquid cleaners or abrasive materials, which can damage the surface or internal components.
- Environment: Keep the device in a dry, well-ventilated area. Avoid exposure to extreme temperatures, direct sunlight, or high humidity.
- Heat Dissipation: The metal shell of the extractor is designed for effective heat dissipation. Ensure that the ventilation slots are not blocked to allow proper airflow.
