Description
The SmartAVI RK8-HDX-POE-S is a high-performance 8-port rackmount HDMI extender transmitter designed to streamline multi-display deployments in professional AV environments. Built for reliability and efficiency, it consolidates up to eight HDMI sources into a single rack unit and transmits video, audio, IR control, and power over a single Cat5e/6 cable per channel.
Ideal for control rooms, digital signage, call centers, and enterprise installations, this solution eliminates the need for multiple standalone extenders and power supplies. With support for Full HD and 4K video, along with advanced audio formats, the RK8-HDX-POE-S ensures high-quality signal transmission up to 250 feet while maintaining clean and organized rack infrastructure.
Engineered for scalability and ease of deployment, this rackmount transmitter enables centralized system design while reducing cabling complexity and installation costs.
