The AX420 HDMI eARC Switch allows for flexible switching between two displays and a sound system with HDMI-ARC or HDMI-eARC. With this innovative device, you can seamlessly switch the audio return channel of your soundbar between two televisions or between a television and a projector. The automatic switching feature detects which display is active and ensures that the sound is always transmitted correctly. This means that no manual switching or cable reconnections are necessary.

The AX420 is designed exclusively for audio transmission and does not support video signals. It supports all common audio formats, including Dolby Atmos, DTS:X, Dolby TrueHD, and DTS-HD. Both the display and the sound system must support eARC to enjoy high-resolution formats. With ARC connections, only the audio formats supported by the ARC standard are available.

Thanks to the HDMI-CEC feature, the volume of the soundbar can be conveniently controlled via the TV remote. Additionally, when powered externally via USB, the switch allows for automatic on and off of the sound system. Without external power, the soundbar must be turned on manually. This ensures seamless integration into your home theater setup and reduces the effort required when switching between different devices.

Installing the AX420 is easy and quick, as no additional software is required. Simply connect the switch to your sound system and the desired displays, and you can start using the audio return channel flexibly. The device can be powered through the HDMI connection of the sound system or optionally via a USB power adapter to ensure reliable operation.
