Description
The SmartAVI SDX-XT-4P-S is a high-performance quad-head DVI-D KVM extender engineered for reliable, long-distance signal transmission in professional AV and IT environments. Designed to extend four independent DVI-D video signals along with USB 2.0, keyboard/mouse control, and stereo audio, this solution enables seamless remote workstation access up to 500 feet over standard CAT5/5e/6 cabling.
Delivering uncompressed video at resolutions up to 1920 x 1200 at 60 Hz, the system ensures crystal-clear image quality with minimal latency, making it ideal for mission-critical applications such as control rooms, data centers, broadcast environments, and collaborative workspaces. Built-in keyboard and mouse emulation maintains continuous system responsiveness, preventing disruptions during operation.
With support for transparent USB 2.0 connectivity, users can extend peripherals beyond basic input devices, enhancing flexibility for advanced workflows. Its robust design, automatic signal equalization, and compatibility across major operating systems make the SDX-XT-4P-S a dependable solution for extending high-resolution video and control across extended distances without compromising performance.
