Four sources is the number most rooms actually land on — a laptop, a player, a console, and the one nobody can identify but everyone insists on keeping. This switcher takes all four at full HDMI 2.1 bandwidth and puts any of them on a single display, by button, IR remote or RS-232 command.

Nothing is throttled to make the count work. Every input runs the complete 48Gbps pipe: 8K at 60Hz, 4K at 120Hz, 4:4:4 colour, HDR10, HDR10+ and Dolby Vision, with ALLM and VRR passed straight through for gaming sources. Auto-switching follows whichever input just came alive, and manual mode locks it down when you would rather decide yourself.

The audio extractor is the part that earns its place in a real install. Digital and analog outputs run in parallel with the HDMI feed, and the analog side has gain control, so a ceiling amplifier or DSP gets a properly levelled signal instead of whatever the display felt like passing on. Add EDID management and the switcher stops being the thing that breaks handshakes and starts being the thing that fixes them.

Feeding an LED video wall?

This unit is the front end of a much bigger picture. Every LED wall we ship needs a clean, stable source path in front of the receiving cards — and the cost of the electronics is a rounding error next to the screen itself. If you are specifying signal gear because a wall is coming, talk to us before you buy the boxes: we will size the whole chain and quote the display with it.
