Kramer MTX3-88-HSA 8x8 Scaler-Based HDMI + Audio Matrix Switcher
The MTX3-88-HSA is a scaler-based 8x8 matrix: every one of its eight HDMI outputs carries its own independent scaler, so a mixed room of displays at different native resolutions each gets a correctly scaled image from any of the eight sources, not a single shared output format. That solves the everyday problem of a matrix feeding one 4K display and one older 1080p panel from the same switch.
An integrated four-in, four-out analog audio matrix rides alongside the video switching, including ARC (Audio Return Channel) sources, so audio routing does not need a separate box. It is built for control rooms and multi-display installations where every output needs to look right regardless of what is plugged into the input side.
