The FeinTech AX340 HDMI 2.1 eARC Pass Switch 4 In 1 Out is perfect for home theater or gaming setups with a soundbar. It connects up to four HDMI devices such as a console, Apple TV, or PC to a display and simultaneously transmits audio via HDMI eARC or ARC to a compatible soundbar. This works reliably even if your display is, for example, a monitor that does not have an eARC port. This way, you can enjoy high-quality sound without being dependent on special TV connections. The switch supports all current video formats such as 4K 120Hz and 8K 60Hz. HDR standards like Dolby Vision, HDR10, HDR10+, and HLG are also passed through. For smooth gaming, features like VRR, ALLM, QMS, and QFT are available. High-quality audio formats such as Dolby Atmos, DTS:X, and Dolby TrueHD are also supported. The AX340 automatically detects active devices, switches inputs as needed, and additionally allows control via remote and HDMI CEC. The Auto Power function ensures that the TV switch and soundbar turn on and off simultaneously.
