Modular Multiviewer with the Fastest Processing on the Market

The KMX-3921 multiformat multiviewer delivers unmatched flexibility with built-in high dynamic range processing and 4K UHD display outputs, making it ideal for live productions. Offering up to 48 multiviewer outputs per 4 RU frame—and expandable to 256 outputs when connected to an upstream router—it provides customizable options to ensure smooth and efficient operations during live events.
The KMX-3921 is the ultimate tool for live production operations. Super-fast processing with only one field of latency make it the quickest on the market. Plus, the KMX-3921 is designed to save space and power, perfect for outside broadcast trucks.
Prepped for the future with 4K outputs for UHD displays and support for high dynamic range/wide color gamut (HDR/WCG). The modular design allows for scalability from 9 to 54 inputs and 1 to 4 outputs using the same building block module.
Introducing HDR and WCG into a live production workflow can be tricky, but not with the KMX-3921. It provides processing for HLG, PQ, and S-Log3 HDR formats, as well as BT.2020 WCG. Each input is customizable, so you can mix and match SDR and HDR sources on the same display.
Achieves processing latencies of just 20 ms at 50 Hz and 16.7 ms at 59.94 Hz, making it perfect for live TV production where real-time performance is essential.
Supports high-quality 3G/HD/SD HDR-ready inputs and 4K UHD outputs, with software-enabled portrait display orientations that require no extra hardware.
Expands up to 54 inputs and accommodates 24 KMX-3921 cards in a 4 RU frame, enabling up to 256 multiviewer outputs when connected to an upstream router for seamless control.
