1. Introducció
The FeinTech AX310 is an advanced HDMI 2.1 audio extractor designed to provide flexible audio routing for your home theater system. It allows you to separate the audio signal from an HDMI source and send it to an eARC/ARC compatible soundbar, while simultaneously passing the video signal to your display (TV, monitor, or projector). This device supports high-resolution video formats up to 8K at 60Hz and 4K at 120Hz, including HDR and Dolby Vision, along with gaming features like Variable Refresh Rate (VRR) and Auto Low Latency Mode (ALLM). It also supports all HDMI eARC audio formats, such as Dolby Atmos, DTS:X, and Dolby True HD. The AX310 is ideal for integrating modern soundbars with displays that lack eARC/ARC functionality or for resolving potential audio delay issues.

6. Instruccions de funcionament
6.1 eARC Audio Extraction
The AX310 can extract audio either directly from the HDMI source connected to its IN port or from the audio return channel (eARC/ARC) of your connected TV. Use the botó eARC on the front panel to switch between these modes. This allows you to ensure your soundbar receives the optimal audio signal, whether it originates from your source device or from smart TV apps.
6.2 Gestió EDID
El EDID switch (1/0) on the front panel allows you to manage the Extended Display Identification Data. EDID communicates the display's capabilities (supported resolutions, audio formats) to the source device. Adjusting this switch can help resolve compatibility issues or ensure specific audio/video formats are prioritized. Refer to the detailed EDID settings in the full manual for specific configurations.
6.3 HDMI CEC Control
The AX310 supports HDMI Consumer Electronics Control (CEC), which enables connected devices to communicate and control each other. This feature allows you to control your soundbar's volume using your TV remote or source device remote, provided that:
- Your TV supports ARC/eARC and has CEC enabled.
- Your source device (e.g., Apple TV, Fire TV) is capable of directly controlling the soundbar.
If you experience issues with volume control via CEC, especially with soundbars that rely on infrared (IR) for volume, you may need to configure your soundbar to learn IR commands from your TV remote or configure your source device to send IR volume commands. Consult your soundbar's and source device's manuals for specific instructions on IR learning or remote control setup.
7. Manteniment
To ensure the longevity and optimal performance of your FeinTech AX310, follow these simple maintenance guidelines:
- Neteja: Use a soft, dry cloth to clean the exterior of the device. Do not use liquid cleaners, aerosols, or abrasive chemicals, as these can damage the finish or internal components.
- Ventilació: Ensure the device is placed in a location with adequate airflow to prevent overheating. Do not block any ventilation openings.
- Emmagatzematge: Quan no l'utilitzeu durant períodes prolongats, guardeu el dispositiu en un lloc fresc i sec, allunyat de la llum solar directa i de temperatures extremes.
- Connexions de cable: Periodically check all HDMI and power cable connections to ensure they are secure. Loose connections can lead to signal loss or intermittent issues.
8. Solució De Problemes
If you encounter issues with your FeinTech AX310, please refer to the following common troubleshooting steps:
- Sense sortida d'àudio:
- Verify all HDMI cables are securely connected to the correct ports.
- Ensure your soundbar is powered on and set to the correct HDMI input.
- Comproveu el botó eARC setting on the AX310. Try toggling it to switch audio extraction modes.
- Ajusteu el Interruptor EDID settings. Incorrect EDID can prevent audio formats from being recognized.
- Confirm your source device and soundbar support the desired audio format (e.g., Dolby Atmos).
- Sense sortida de vídeo:
- Ensure the AX310 is powered on (Power indicator should be lit).
- Check all HDMI cables for secure connections. Try different HDMI cables if possible.
- Verify your display is powered on and set to the correct HDMI input.
- Test the source device directly connected to the display to rule out source or display issues.
- Audio Delay (Lip Sync Issues):
- While the AX310 is designed to mitigate audio delay, some systems may still require adjustments. Check for audio delay settings on your TV, soundbar, or source device and adjust as needed.
- Ensure the latest firmware is installed on all devices, including the AX310 (if available via the SERVICE port).
- HDMI CEC Control Not Working:
- Ensure CEC (often called Anynet+, Bravia Sync, Simplink, etc.) is enabled on your TV and source devices.
- Verify that your TV's ARC/eARC port is being used for the AX310's TV output.
- If your soundbar uses an IR remote for volume, you may need to configure your soundbar to learn the IR codes from your TV remote, or configure your source device (e.g., Apple TV) to send IR volume commands. Refer to your soundbar and source device manuals for IR learning instructions.
