HDMI Audio Extractor
The AX211 HDMI 2.1 Audio Extractor is a powerful solution for seamlessly transmitting sound from an HDMI source to your HDMI sound system. It passes the audio signal through an HDMI output while simultaneously allowing lossless transmission of the video signal to your display. Whether modern TVs, older AV receivers or gaming headphones with an HDMI connection - the AX211 is ideal for all setups.
Whether you're using gaming consoles like the PS5 or Xbox, a PC, or streaming boxes like Apple TV and Fire TV, the AX211 offers the flexibility to combine older sound systems with new displays, supporting high-resolution sound formats like Dolby Atmos and DTS:X to ensure an immersive sound experience.
The AX211 optimizes audio transmission by eliminating possible latency, ensuring audio quality remains high at all times. The AX211 can also play audio formats that your TV may not support, such as DTS, so you can get the most out of your audio sources, regardless of the TV's limitations. With support for the latest HDMI standards, the AX211 guarantees outstanding audio and video quality for all your entertainment needs.
Supports resolutions up to 8K 60Hz and 4K 120Hz
The AX211 supports impressive resolutions of up to 8K at 60Hz HDR and 4K at 120Hz, with a maximum data rate of 48 Gbps. Thanks to backward compatibility to lower resolutions, the AX211 ensures lossless video and audio transmission, regardless of the source used. In addition, it offers HDMI 2.1 gaming features such as Variable Refresh Rate (VRR), which reduce image stuttering and enable smooth gameplay. Auto Low Latency Mode (ALLM) ensures that latency is automatically minimized, further improving response time in games. This means you can enjoy the best picture and sound quality both when gaming and streaming.
ARC support
Thanks to ARC (Audio Return Channel) support, the AX211 enables seamless audio transmission from the TV to the connected sound system. Simply connect the AX211 to the HDMI-ARC or HDMI-eARC port on your display and activate the eARC function. The AX211 automatically detects whether the sound is coming from the connected source or the TV, ensuring effortless switching. This function improves your home theater experience by creating an easy connection between your TV and the sound system while ensuring high-quality audio output. Whether you're streaming movies or playing games, you'll always get the best sound. In addition, it's possible to connect a monitor or video projector without ARC function and deactivate eARC, giving you flexibility in choosing your devices.
Flexible EDID management: Customize audio and video formats
The AX211 features flexible EDID management that allows you to customize the maximum supported audio and video formats. The integrated dip switch lets you choose between different EDID modes to ensure that your audio and video output is optimally tailored to your connected devices. This improves compatibility with different displays and sound systems and prevents potential conflicts in signal output. With this feature, you can ensure that both image 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 control. This feature makes operation easier as you do not need a separate remote control for your soundbar. In addition, many streaming devices, such as Apple TV or Fire TV, also offer the option of controlling the audio system independently, which gives you additional flexibility in operation.
switching on and off
By long pressing the eARC button you can turn the extractor on or off.
