2. Optimized Signal Distribution and Long-Distance Extension
Ideal for mixed-resolution environments, this 4K HDMI matrix extender features independent 4K-to-1080p downscaling on each output, allowing you to connect both UHD and Full HD displays without compromise. Its HDBaseT outputs extend signals up to 150 meters (492 feet) at 1080p and 120 meters (394 feet) at 4K via a single CAT5e/6/7 cable, while Power over Cable (PoC) reduces the need for multiple power supplies. This streamlined setup is perfect for commercial applications like video walls, conference centers, classrooms, and large-scale digital signage networks.
3. Advanced Audio Capabilities and Device Compatibility
For complete audio flexibility, the matrix supports 7.1-channel audio pass-through formats including LPCM, Dolby TrueHD, and DTS-HD Master Audio, while offering audio de-embedding through analog RCA and coaxial outputs. The built-in IR matrix enables bi-directional IR routing, allowing remote control of source devices from display zones. Comprehensive EDID management and CEC pass-through further enhance device communication and integration, ensuring reliable signal negotiation across your entire AV setup.
4. Flexible Control Options and Professional-Grade Design
Control is flexible and user-friendly via front panel buttons with OLED display, IR remote, RS-232, LAN, or WebGUI. Designed with a 1U rack-mountable chassis, this HDMI matrix switch is built for 24/7 reliability in demanding environments. Whether you're managing a control room, outfitting a commercial AV installation, or upgrading a 4K matrix extender system, the UHD88-EXB230R-K offers scalable performance, robust feature support, and uncompromising signal quality.
