What problem does the KUMO 6464-12G solve?
In high-end broadcast, live production, and OB (outside broadcast) environments, managing multiple 4K or 8K video signals quickly and silently is a constant challenge. Traditional routers that support 12G-SDI often come with noisy fans, large rack footprints, or limited integration capabilities — not ideal when space, heat, and sound are critical concerns. That’s where AJA’s new KUMO 6464-12G router comes in: a compact, fanless 64x64 SDI router designed specifically to meet the bandwidth and operational demands of today’s UHD workflows, without the noise or bulk.
What was the industry workaround before this?
Before routers like this, engineers typically had to combine multiple lower-bandwidth 3G or 6G routers to manage high-resolution signals, leading to complex wiring and signal degradation risks. Others had to accept fan noise as the trade-off for performance, which created issues in audio-sensitive environments like sound stages or mobile trucks. Larger routing systems also meant giving up valuable rack space, increasing heat output and power consumption — all of which can impact workflow flexibility and reliability.
How does the KUMO 6464-12G help?
AJA has packed a lot into this 4RU unit. It delivers 64 inputs and 64 outputs of 12G-SDI signal support, giving operators the ability to route full-resolution 4K (and even 8K) signals using a single cable per path. The fanless design is a standout feature — keeping environments completely silent, which is critical in places where mics are live and space is tight. It also includes dual redundant power supplies for reliability and supports RS-422 protocols (including Grass Valley native) and Ethernet-based control. This means it can slot into existing control setups effortlessly, and users can quickly switch between saved signal paths (salvos) — perfect for managing multiple productions or setups on the fly.
Who would this appeal to?
The KUMO 6464-12G is a great fit for professionals working in OB trucks, live events, flypacks, studios, or post facilities — anywhere that needs robust, quiet signal routing. It’s especially appealing for teams managing UHD or HDR content who can’t afford to sacrifice signal integrity, speed, or audio clarity. Broadcasters, technical directors, and engineers looking to future-proof their routing infrastructure while keeping things compact and quiet will likely find this router ticks all the boxes.
With shipping already underway, the KUMO 6464-12G is more than just a new product — it’s a smart answer to the evolving demands of 4K and 8K production environments.
