HDMI Audio Extractor

The AX310 HDMI Audio Extractor routes the audio signal from an HDMI source device directly to your sound system via the HDMI ARC or eARC port. Meanwhile, the video signal for your display is passed through losslessly, allowing you to enjoy both high-quality pictures and impressive sound. Ideal for use with modern soundbars, the extractor allows you to extract the audio format regardless of the display's supported formats. It also eliminates audio delay (latency), allowing playback of audio formats like DTS that may be blocked by the TV. This ensures your home entertainment system always delivers the best sound experience.

Supports resolutions up to 8K 60Hz and 4K 240Hz

The AX310 supports impressive resolutions of up to 8K at 60Hz HDR and 4K at 240Hz, with a maximum data rate of 48 Gbps. Thanks to backward compatibility to lower resolutions, the AX310 guarantees lossless video and audio transmission, regardless of the source used. It also offers HDMI 2.1 gaming features such as Variable Refresh Rate (VRR), which reduce image judder and enable smooth gameplay. Auto Low Latency Mode (ALLM) ensures that latency is automatically minimized, further improving response time in games. This allows you to enjoy the best picture and sound quality for both gaming and streaming.

ARC support

Thanks to ARC (Audio Return Channel) support, the AX310 enables seamless audio transmission from your TV to the connected soundbar. Simply connect the AX310 to your display's HDMI-ARC or HDMI-eARC port and enable the eARC function. The AX310 automatically detects whether the sound is coming from the connected source or the TV, ensuring effortless switching. This feature enhances your home theater experience by creating a simple connection between your TV and soundbar while ensuring high-quality audio output. Whether you're streaming movies or playing games, you'll always get the best sound. It's also possible to connect a monitor or video projector without ARC functionality and leave eARC disabled, giving you flexibility in your device selection.

Flexible EDID management: Customize audio and video formats

The AX310 features flexible EDID management, allowing you to individually configure the maximum supported audio and video formats. Using the integrated DIP switch, you can choose between different EDID modes to ensure your audio and video output is optimally tailored to your connected devices. This improves compatibility with various displays and soundbars and prevents potential signal output conflicts. This feature ensures that both picture and sound quality remain at the highest level, regardless of the source or connected device.

Volume control via the TV remote control with HDMI-CEC

With a TV that has an HDMI ARC or eARC connection, you can control the volume of your audio signal directly from the TV remote. This feature simplifies operation, as you don't need a separate remote for your soundbar. In addition, many streaming devices, such as Apple TV or Fire TV, also offer the ability to control the audio system independently, giving you additional flexibility in operation.

Switching on and off

By long pressing the eARC button you can turn the extractor on or off.
