HDMI 2.1 switch with 4 inputs and 1 output

The AX340 HDMI switch allows you to connect up to four HDMI devices, such as PS5, Xbox, Apple TV, PCs, or set-top boxes, to a single display. You can easily switch between different devices without constantly reconnecting cables. The switch is compatible with various display types, including TVs, projectors, and monitors. With the convenient auto-switching function, the switch automatically detects the last activated device and switches to it, so you can always use the device you want. Ideal for a flexible home theater or gaming setup.

HDMI Audio Extractor for eARC and ARC Soundbars

The AX340 HDMI Audio Extractor routes the audio signal from your HDMI device directly to your sound system via the HDMI ARC or eARC port, while passing the video signal losslessly to your display. This technology not only ensures excellent picture quality but also an instantaneous sound experience by eliminating audio latency. Particularly suitable for modern soundbars, the Audio Extractor enables playback of audio formats such as DTS or Dolby Atmos, which may be blocked by the TV. With support for eARC and ARC, you can enjoy a seamless, high-quality audio and video experience.

Experience an immersive audio experience with Dolby Atmos

The AX340 delivers impressive, immersive sound by transmitting audio formats like DTS:X, Dolby Atmos, and Dolby TrueHD from your connected media players to your sound system—even if your display (TV, projector, or monitor) doesn't support them. This lets you unlock the full potential of modern audio formats and enjoy a cinema-quality home theater experience. Regardless of whether your display supports the audio formats, the AX340 ensures that your sound system always delivers the best possible sound quality.

HDMI 2.1 support for modern video formats

The AX340 HDMI 2.1 switch offers support for the latest video formats and ensures exceptional picture quality. With a maximum resolution of up to 8K at 60Hz and 4K at 120Hz, you can enjoy crisp, vivid images on your display. These features are especially important for gaming, enabling smoother, more responsive experiences.

Thanks to HDMI 2.1, the AX340 also supports advanced features such as VRR (Variable Refresh Rate), ALLM (Auto Low Latency Mode), QMS (Quick Media Switching), QFT (Quick Frame Transport), and SBTM (Sports Mode). These features ensure smooth, judder-free image display and fast response times, which are especially beneficial for gaming and live broadcasts.

The AX340 is not only optimized for the latest displays but also backward compatible with older devices. So you can enjoy high picture quality even at lower resolutions and with older video formats. With support for HDR10, HDR10+, HLG, and Dolby Vision, colors and contrast are reproduced vividly and with rich detail, ensuring an impressive visual experience, especially with HDR content.

Whether you're streaming movies, streaming content, or playing games, the AX340 always delivers excellent picture quality on your display.

This feature ensures stable, lossless audio transmission and enhances your home theater experience by creating a simple and direct connection between your TV and the soundbar. Whether you're streaming movies or playing games, your sound system always delivers the best sound. You can also connect devices without ARC support, such as monitors or projectors, and disable the eARC function if needed for maximum flexibility.

Seamless HDMI eARC support for TV and soundbar

The AX340 supports both HDMI eARC and ARC, enabling effortless and seamless audio transmission from your TV to your connected soundbar. Simply connect the AX340 to your TV's HDMI eARC port and enable the eARC function. The switch automatically detects whether the audio is coming from the TV and switches the audio output to HDMI ARC/eARC as soon as a signal is detected. This allows you to switch between audio sources without manual intervention.

Automatic switching for more comfort

The AX340 HDMI 2.1 Switch offers a convenient auto-switching function that simplifies switching between your connected devices. The switch automatically detects the last connected device and seamlessly switches to it without you having to manually change the input. This allows for quick setup and more flexibility in selecting your desired device, be it a PS5, Xbox, PC, or other HDMI-enabled device.

Thanks to the included remote control, you can also quickly and easily switch between devices and adjust the audio formats to your needs. Manually switching devices is a thing of the past – the AX340 ensures a smooth process.

Please note that this feature is not supported by all HDMI devices. Players like Apple TV or Shield TV do not completely shut down, meaning fully automatic switching is not possible with these devices.

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.

Auto-power function for automatic on/off

The AX340's Auto Power feature ensures that both the switch and the sound system connected to the HDMI port turn on or off automatically. As soon as you turn on your TV, the AX340 activates, and the connected sound system also starts up. When you turn off the TV, the AX340 and the sound system turn off simultaneously—all without manual intervention.

However, you can also manually turn the AX340 on or off using the included remote control. If you want to disable the auto-on/off function, simply press the eARC button on the device for 5 seconds. Please note that HDMI eARC must be enabled on the AX340 for this function to work correctly.

Easy installation and operation:

The FeinTech AX340 HDMI 2.1 eARC Pass-Through Switch 4 In 1 Out is particularly user-friendly and allows for straightforward installation. Simply connect your devices to the switch and select the desired HDMI input – the AX340 takes care of the rest!

Thanks to its broad compatibility, the AX340 supports all common HDMI devices, including modern TVs, monitors, and projectors. Even older HDMI devices are seamlessly supported, giving you maximum flexibility in your device selection.

The "Soundbar (eARC)" port transmits audio to a sound system that must have an HDMI output with HDMI eARC or HDMI ARC. HDMI ARC and eARC ports on the sound system are usually labeled "ARC," "eARC," or "TV eARC/ARC." These special ports are designed to receive audio from the TV.

If, contrary to expectations, a device is incompatible, you can always contact our support team. The AX340 can be updated with new firmware via the USB-C interface to expand compatibility and resolve potential issues.

Optimal cable lengths and expansion options

For best performance, we recommend a cable length of less than 2 m for HDMI connections at 8K/4K 120Hz and less than 5 m for 4K 60Hz. For longer distances, HDMI fiber optic cables can be used to ensure stable signal transmission. For the eARC connection from the HDMI Audio Extractor to the soundbar, we recommend a maximum cable length of 10 m.
