Kaleido-KMX-3921

HDR-Ready Modular Multiviewer

Grass Valley's Kaleido multiviewer is optimized for reduction in space and power to meet the challenges of outside broadcast trucks. With up to 48 multiviewer outputs per 4 RU frame, the KMX-3921 can be expanded up to 256 multiviewer outputs when connected to an upstream router. Designed with live production operations in mind, the KMX-3921 offers the fastest processing on the market with only one field of latency. Ready for the future with 4K outputs for UHD displays and high dynamic range/wide color gamut (HDR/WCG) support, the KMX-3921 modular design is scalable from 9 to 54 inputs, and 1 to 4 outputs using the same building block module.
