AJA KUMO 6464-12G 64x64 Compact 12G-SDI Router for 4K/UltraHD and 8K Workflows

The AJA KUMO 6464-12G is a compact, broadcast-ready 64x64 12G-SDI router built for high-capacity signal routing in modern production environments. With 64x 12G-SDI inputs and 64x 12G-SDI outputs, it maps any input to any number of outputs through a powerful crosspoint matrix—helping you route signals cleanly without relying on additional patch panels or distribution amplifiers.

Designed for demanding 4K/UltraHD and 8K/UltraHD2 workflows, KUMO supports single-link 12G-SDI for 4K/UltraHD and offers ganged dual-link or quad-link routing when you need to group ports for higher-resolution routing. Control is flexible and practical for real facilities and trucks, with an embedded web server for remote control, network connectivity, RS-422 support, and compatibility with AJA KUMO control panels for fast, confidence-inspiring operation.

For environments where noise matters, the fanless design supports silent operation—ideal for on-set use, audio-sensitive rooms, and other quiet installations. With robust switching behavior designed for professional SDI, plus configurable salvos and presets, the KUMO 6464-12G is a dependable routing core for virtual production, post facilities, mobile trucks, live events, and high-density AV infrastructure.

Key Features of the KUMO 6464-12G 12G-SDI Router
