Flexible audio switching between two displays

The AX420 allows you to easily switch audio between two displays - be it a TV and a projector or two TVs. This saves you from having to constantly switch cables and you can enjoy perfect sound on all devices via your soundbar. The perfect solution for a flexible home cinema setup.

Automatic display detection and switching

The AX420 automatically detects which display (TV or projector) is switched on and seamlessly switches the audio signal. This means you no longer have to worry about switching manually - the switch does it for you. This means the setup is always ready as soon as you switch on your device.

Get more out of your eARC system – flexible and powerful

The AX420 connects your sound system to your TV and projector via the eARC/ARC ports to transmit the internal TV sound directly to your soundbar. Enjoy the sound from streaming apps and the internal tuner without the hassle of replugging. Please note that the AX420 does not transmit video signals - it is therefore best to connect external players directly to your TV.

Easy to use: Perfect control with HDMI-CEC

The AX420 ensures maximum ease of use: With HDMI-CEC, you can easily control the volume of your soundbar using the remote control of your active TV. The automatic on/off function makes things even more practical: as soon as one of the two connected displays is activated, your sound system also switches on automatically (when powered via USB). These features make your home cinema setup not only smarter, but also more relaxed.

AX420 HDMI eARC Switch for 2x TVs and 1x sound system – Flexible switching between two displays and a soundbar

  • Switches the HDMI-ARC or HDMI-eARC connection of a soundbar between 2 displays (TV, projector).
  • Automatic switching: automatically detects which display is switched on and switches the audio signal (when powered by optional USB port)
  • Supports Audio Return Channel (ARC/eARC) from displays to sound system. No video transmission, only audio.
  • Compatible with all major audio formats, including Dolby Atmos and DTS:X.

World first for flexible audio switching

The AX420 is the first device of its kind to enable audio transmission for two displays via HDMI-ARC/eARC. This innovative solution solves the problem that many sound systems can only be connected to one TV and gives you more flexibility in your home theater setup.

Easy switching between two displays with ARC/eARC

With the AX420 you can easily switch between two TVs or a TV and a projector without having to constantly unplug the cables. This way your soundbar always stays connected and always delivers the best sound. Important: Both displays and the sound system must support ARC or eARC.

This means you can play the sound from apps and internal tuners through the soundbar without having to unplug anything. Sound from devices that are connected directly to the TV can also be played this way - for even more flexibility and the best sound.

Automatic display detection

The AX420 detects which display (TV or projector) is currently active and automatically switches the audio signal. You no longer have to worry about switching manually - the switch does it for you and ensures that you always have the right sound when you turn on the device.

Support for all common audio formats

The AX420 supports all common audio formats. These include high-resolution formats such as Dolby Atmos, DTS, Dolby TrueHD and DTS-HD. In order for the AX420 to support all eARC audio formats, both your display and sound system must support HDMI-eARC. If you use a display or sound system with HDMI-ARC, only the audio formats that can also be transmitted via HDMI-ARC are supported. Enjoy clear, detailed sound with all modern audio formats for a perfect home theater experience.

HDMI-CEC volume control

Thanks to the HDMI-CEC function, you can easily control the volume of your soundbar using your TV remote control - without any additional devices or apps. This function not only saves you time but also ensures a simple and convenient user experience.

Automatic switching on and off of the soundbar

If you power the Switch with a USB port or USB power adapter, the Switch will automatically turn on the sound system when either TV is turned on. If connected without USB power, the soundbar must be turned on manually. This ensures a seamless user experience and reduces hassle.

Easy installation

The AX420 is compatible with all common HDMI-ARC and HDMI-eARC devices, including modern soundbars and AV receivers. Installation is quick and easy as no additional software is required. Simply connect the AX420 eARC Switch to your sound system and your two displays, optionally supply it with power and save yourself the hassle of manually replugging your home theater setup.

Please note : No video signals are transmitted through the AX420. If connected to an AV receiver, any players connected to it will not be able to provide an image. External players should be connected directly to the TV.

Power supply

The AX420 can be powered either by the connected sound system via HDMI or with the included USB-C to USB-A cable. A USB power adapter is not included.

We recommend external power supply via a USB power adapter (5 V DC, 500 mA or more), as this supports automatic switching of the sound system on and off and ensures reliable operation.

Unfortunately no video transmission but only audio

Certainly a good product, but unfortunately I overlooked the fact that it only works in conjunction with a soundbar and not with a TV receiver, as no video signal is transmitted. Accordingly, I am still looking for a solution for an HDMI eARC switch on a TV receiver for TV output and projector output. Both are SmartTV devices and require HDMI eARC for full functionality.

That would be desirable, but it is not yet possible. ARC and eARC were developed exclusively for the connection between a television and a sound device. The AX420 is the only device that offers a solution for using 2 TVs on the sound system. If the integrated apps are not enough, an external player can be operated directly on the TV or video projector.

eARC Switch AX420

The product is of high quality. Unfortunately, the automatic switching of inputs only works with one input.
