4K, 3G, HD, SD Support

Upgrading a facility or mobile unit is not always an all-at-once process.
A certain amount of overlap exists where a mixture of signals have to all coexist within the same architecture.

KUMO routers are designed to upgrade as you do. With a simple setting change, KUMO routers can be configured for ganged dual and quad port routing, allowing multiple inputs and outputs to be grouped together for Dual Link, 4K and UltraHD workflows. This allows seamless routing of uncompressed or RAW 4K and UltraHD signals throughout a production or post facility. Then switch the router back to HD/SD operation as needed, giving you the flexibility to route virtually any format in your facility.

Redundant Power Supplies

Routers are a key piece of infrastructure at the heart of a facility. Downtime is not an option, especially in critical installations.

Every KUMO router is equipped with dual, redundant power supplies to ensure continuous up-time even in the unexpected event of a power supply failure. Front panel indicators and web UI warnings inform you if a power supply goes offline, allowing for replacement while the router is still operational.

Industry-Leading Support

AJA’s technical support is recognized as one of the best in the industry and is available at no extra charge to all AJA customers. If you need assistance with any aspect of KUMO installation, configuration or operation, AJA support will work with you to get up and running.

Also, KUMO routers are covered by AJA’s 5-year international warranty and advance replacement. Replacement units, if needed, are shipped immediately and the previous unit can be shipped back to AJA once the issue has been resolved.
