Compact, robust and built for critical production environments, KUMO Compact SDI routers offer flexibility and quality that exceeds SMPTE specifications at an unprecedented price. KUMO SDI routers are available in three configurations: KUMO 3232 supports 32 3G SDI inputs and outputs, KUMO 1616 supports 16 3G SDI inputs and outputs and KUMO 1604 supporting 16 3G SDI inputs and 4 3G SDI outputs.

Compact routing

KUMO compact SDI routers provide powerful signal control and support full broadcast specifications over 3G SDI, with quality that exceeds SMPTE specifications. The super-compact 1RU and 2RU formats are just a few inches deep, making them a perfect fit for any broadcast, production, or post production environment, from mobile sports trucks and edit suites, through to corporate video installations or live theatrical A/V rigs.

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.

Powerful signal control

KUMO’s powerful cross-point routing matrix maps any input to any number of outputs without the need for additional patch panels or distribution amplifiers. Use KUMO as an affordable distribution amplifier by routing a single input to all outputs. Used in this way, a KUMO 3232 can take the place of multiple distribution amplifiers.

Broadcast quality

Designed for critical broadcast, production and post environments, KUMO routers are built to AJA’s demanding quality standards, which exceed SMPTE specifications. As data rates increase, such as with 3G signals and 4K workflows, higher tolerances are required in order to maintain signal quality.

AJA’s exacting standards ensure that KUMO routers will handle any signal you throw at it.

Simple installation and configuration

Running Embedded Linux, KUMO routers are network-ready and support powerful HTTP control and monitoring via a web browser - without the need for any additional software.

KUMO's auto-detect Bonjour™/Zeroconf protocols mean that network configuration is automatic, just connect KUMO to your network or a computer and the system will self-configure, ready for use. Alternatively, standard network configuration allows access to each KUMO via its default IP address. Once connected to KUMO using a web browser, you can configure the full TCP/IP settings, select and name KUMO routers, name sources and destinations, and perform all operational functions.

KUMO routers are easily integrated with existing infrastructure utilizing the industry-standard Grass Valley Native Protocol over RS-422 or even Ethernet. Ethernet network connectivity also allows you to control all KUMO routers from any web browser on a network-connected device, ensuring you have the control you need from any location.

KUMO Control Panel

KUMO CP is an optional 1RU control panel that can be used in standalone or networked configurations.

Connecting via Ethernet to the same network as the KUMO routers, KUMO CP enables full control from any location without the need for a computer. Up to four KUMO routers can be controlled from a single control panel.

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.


Whether you’re building a mobile truck, edit suites or an AV flypack, get the routing capabilities you need at a price that fits well within your budget. And KUMO routers are so affordable they can even be used in place of traditional DAs to distribute signals to multiple locations. KUMO routers provide an incredible price/performance ratio while still maintaining the highest quality standards.

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.
