Description
The Kramer MTX3-88-HSA is a high-performance 8×8 scaler-based HDMI matrix switcher designed for professional AV environments requiring ultra-fast switching, advanced scaling, and flexible audio routing. Each of its eight HDMI inputs can be independently routed to any of the eight HDMI outputs, with integrated up/down scaling to ensure compatibility across mixed-resolution displays and sources.
Built for seamless presentations, MTX3-88-HSA offers sub-1-second clean switching, multiview capabilities, user-defined splash screens, OSD overlays, and intelligent EDID handling through Kramer’s I-EDIDPro™ technology. Its integrated audio matrix supports analog and ARC audio routing, enabling fully independent audio breakaway to local sound systems or directly to displays.
With secure IP control, RS-232 support, intuitive front-panel operation, and a 1U rack-mountable design, the MTX3-88-HSA delivers professional-grade performance for conference rooms, command centers, classrooms, digital signage, and high-end AV installations.
