Use the Marmitek Connect 621 UHD to connect 4 HDMI devices to your TV at the same time. This HDMI 2.0 switcher is suitable for displaying Ultra HD 4K resolution, 50Hz, HDR, Deep Color, and 4:4:4 chroma colors. This way, you can enjoy the latest Ultra HD content and watch Netflix or a Blu-ray movie in true-to-life colors. Connect an AV receiver to the extra digital audio output with 1 cable. The switch supports Dolby Atmos and DTS. You can control up to 10 separate speakers, which makes it seem as if the sound is coming from all angles. The integrated audio extractor makes sure you can also use the television's ARC function when your home cinema set doesn't support this. The switch has a separate infrared receiver, so you can place it out of sight.
