Description
The Kramer MTX3-88-PR-PRO is a premium all-in-one 8x8 hybrid presentation matrix engineered for high-performance 4K60 (4:4:4) AV switching, advanced video processing, and flexible USB-C/HDMI/HDBaseT 3.0 signal routing. Designed for modern collaborative spaces, it combines fast switching, ProScale™ image processing, multiview layouts, and dual video-wall capabilities—making it ideal for boardrooms, lecture halls, command centers, and hybrid meeting environments.
This powerhouse matrix integrates comprehensive audio functionality including a full DSP engine, Dante and USB audio routing, dual-zone power amplification, and multiple analog inputs/outputs for complete audio management. With support for wired and wireless casting, USB-C 60W charging, enterprise-grade security, and robust room-control features (RS-232, relays, GPIO), the MTX3-88-PR-PRO delivers unmatched versatility in a single 3U rackmount chassis.
Featuring eight HDBaseT 3.0 ports with configurable direction (input or output), the unit can power remote devices via PoE, extend AV, USB, Ethernet, and control signals up to 100m, and adapt to any deployment scenario. Integrated web-based management and API control offer streamlined installation, monitoring, and configuration for professional AV integrators.
