The KUMO 6464 Compact 64x64 3G-SDI Router from AJA offers 64 inputs and 64 outputs of 3G-SDI video and audio, while maintaining a slim and compact 4 RU profile. The router has elegant and powerful web-based network control, and supports any SDI-based signal up to 3G-SDI, including HD and even 4K/Ultra HD signals. Built with high-quality standards, the KUMO 6464 Router is ideal for any installation where a balance of size and routing capacity are critical.

Compact Routing

  • Compact SDI router provides powerful signal control and supports full broadcast specifications over SD-SDI, HD-SDI, and 3G-SDI, with quality that exceeds SMPTE specifications
  • Compact 4 RU size is just a 1.5” deep, making it a suitable fit for any broadcast, production or post-production environment, from mobile sports trucks and edit suites to corporate video installations or live theatrical A/V rigs
  • Offers 64 3G-SDI inputs and outputs

Powerful Signal Control

  • KUMO’s powerful crosspoint routing matrix maps any input to any number of outputs without the need for additional patch panels or distribution amplifiers
  • Can be used as a distribution amplifier by routing a single input to all outputs
  • Can be configured for ganged dual and quad port routing, allowing users to group together multiple inputs and outputs for dual-link, 4K, and Ultra HD workflows, which allows for seamless routing of uncompressed or Raw 4K and Ultra HD signals throughout a production or post facility
  • You can switch the router back to HD/SD operation as needed, giving you the flexibility to route virtually any format in your facility

Broadcast Standard Reliability

  • Designed for critical broadcast, production, and post-production environments
  • Use of premium components coupled with dual redundant power supply ensures high signal quality and maximum uptime, even in the unexpected event of a power supply failure

Simple Installation and Configuration

  • Running embedded Linux, the KUMO router is network-ready and supports powerful HTTP control and monitoring via a web browser, without the need for additional software
  • You can activate auto-detect Bonjour/Zeroconf protocols that enable automatic network configuration by connecting the router to your network or a computer
  • Standard network configuration allows access to each router 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
  • Easily integrates 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

In a studio situation where we may be using a Blackmagic switcher on some days, and a Convergent Design Apollo on others...would this make swapping cameras between switchers easier?
Asked by: Bill
one reviewer mentioned the cleanswitch. be aware, if this is for live production, the cleanswitch will add a full second of latency. if you don't need clean switching mid-presentation, get the normal unit, or this AJA unit.

Does this unit matches framerate and size of ins and outs, or everything needs to be settled to match previously?
Asked by: Nicols
This unit does not have scaling built in. All Resolutions and Frame Rates need to match before it reaches the Kumo 3232 Router.

Can it switch SDI standards other than 12-G also?

Can it switch SDI standards other than 12-G also?
Asked by: William
Normally, 12G-SDI gear is backwards compatible with 3G-SDI &amp; 6G-SDI, but AJA specifically designed other matrix switchers for that purpose, as follows: For 12G-SDI, look to KUMO 6464-12G for 64x 12G-SDI inputs and outputs, KUMO 3232-12G for 32x 12G-SDI inputs and outputs or KUMO 1616-12G for 16x 12G-SDI inputs and outputs. For 3G-SDI, KUMO 6464 offers 64x 3G-SDI inputs and outputs, KUMO 3232 has 32x 3G-SDI inputs and outputs, KUMO 1616 has 16x 3G-SDI inputs and outputs and KUMO 1604 provides 16x 3G-SDI inputs and 4x 3G-SDI outputs.

Trying to compare to BM 12x12 router. Does Kumo have reclocking on all SDI inputs? How loud is the fan? The BM is unbearable loud
Asked by: James
The SDI connections will re-clock. This product is designed to allow you to assign any of the 16 SDI inputs to any of the 16 outputs. Because of that you should expect it to make some level of noise from the fan cooling it down.

what is the lag in-between switches like ? considering using in an iMag environment
Asked by: MACAULAY
According to AJA, if a route exists in the KUMO and the incoming signal is connected to the KUMO input, the delay time between the incoming signal and the output signal is less than 5 ns.

Asked by: MACAULAY
For monitoring you can connect this to a network and from there use an HTTP web browswer for control and monitoring.
