Key Digital KDDA1X4DC HDMI 1×4 Distribution Amplifier
The Key Digital KDDA1X4DC is a professional-grade HDMI distribution amplifier designed to send one HDMI source to up to four displays simultaneously. Built for modern AV systems, it supports full-bandwidth 4K video, advanced HDR formats, and high-resolution surround audio, while maintaining rock-solid signal stability across all outputs.
Ideal for home theatres, commercial installations, digital signage, and mixed-resolution environments, the KDDA1X4DC can automatically down-convert 4K signals to 1080p when needed. This makes it easy to run a single source to both newer 4K displays and older Full HD screens without compatibility issues.
