The AVProConnect AC-MX44-AUHD is an 18Gbps 4K60 4:4:4 4x4 matrix switch featuring Toslink audio output support up to Dolby 7.1, DTS and LPCM, as well as on-board audio delay control for TV video lip-syncing.
The switch claims to equalise and amplify the output to ensure the HDMI signal can be transmitted through long HDMI signals without quality loss. Meanwhile built-in 1080p to 4K and 4K to 1080p scaling on each output allows for EDID management. Fully matrix-able audio allows one to move the audio signal independently from the video signal at any of the de-embedded audio outputs.
