for a matrix of multiple users accessing and controlling multiple HDMI sources 

Gefen's AV over IP solutions continue their tradition of providing high performance, scalable, expandable, and secure AV routing and distribution over a standard Gigabit Local Area Network. Gen 2.0 KVM products offer enhanced performance, features, and functionality such as 4K Ultra-HD with HDR support, built-in scalers, video-wall control, independent USB, RS-232, IR, and audio routing**, and backward-compatibility with Gefen's first-generation products. Each Sender and Receiver extends and routes video, USB, 2-way audio, RS-232, and IR.

EXT-UHDKA-LANS-TX and RX feature maximum input resolution of 4K @ 60Hz 4:2:0, and maximum output resolution of 4K @ 30Hz 4:4:4. HDCP 2.2 and 1.4 are also supported. 7.1 channels of HBR (High Bit Rate) lossless and LPCM digital audio can pass through the system as well.

The Sender unit features a video output for local monitoring of the source. USB, RS-232, 2-way IR, and audio can be routed independently** between any Sender and Receiver unit, allowing end-users to control any of the sources and the displays within their network. With this greatly expanded array of cutting-edge features and performance, Gefen AV over IP products fully address the ever-growing needs of systems integrators.

The Receiver features a built-in scaler to help optimize the image for a variety of displays and different viewing environments. It also includes a powerful video wall controller that accommodates any screen configuration up to 16x16 and provides great flexibility in sizing and manipulating live and signage content in demanding installations.

Digital and analog audio break-out de-embeds audio from the video and sends it to a separate audio system, enhancing the impact of presentations. This feature, along with analog audio inputs and outputs, make these products perfect to use in collaborative and interactive installations. To ensure maximum versatility and compatibility, the audio outputs on the Receiver units are compatible with both headphones and line level devices such as powered speakers.

The Receiver's integrated USB hub with two USB 2.0 and two USB 1.1 ports accommodates touch panels, keyboard and mouse, and a variety of supported devices.

The KM Emulation feature facilitates real-time, simultaneous keyboard and mouse control of each source from all connected workstations, eliminating the inherent limitations of earlier systems.

Power-over-Ethernet allows the Sender and Receiver units to be powered through a standard PoE-enabled IP network switch, without the need for external power supplies.

When used in conjunction with EXT-CU-LAN Matrix Controller, system configuration is automated and quick. Its Mass-Firmware-Update feature keeps firmware for the entire system up-to-date without the need to access and upgrade each unit separately. Enhanced network security by separating the control and AV networks is also made possible with the EXT-CU-LAN. Other control options include front panel buttons, web server interface, Telnet, UDP, and the Gefen Keyboard Switching Controller software (available for download at www.gefen.com).

Gefen's Enhanced API provides added functionality and facilitates use with third party controllers.


The Gefen Gen 2.0 AV over IP products have been specifically designed for use with Gefen Syner-G™ software. Gefen Syner-G™ Discovery and Show-Me features greatly simplify initial IP configuration.

Each cable run from a Sender to a Receiver or from a Sender or Receiver to the network switch can be up to 330 feet (100 m).

A built-in 2-port Gigabit switch on the Receiver allows daisy-chaining of additional Receivers or other IP-enabled devices. In applications such as digital signage, where there is a need to replicate content on multiple displays, the ability to cascade Receivers removes the requirement for each cable to be run directly to the main network switch, thereby extending the range of these units far beyond the limits of a point-to-point video distribution system.

Sender and Receiver can be used as KVM extenders in a one-to-one system, or as nodes in a virtual matrix environment where any source can be routed to any or all displays, supporting up to 39,900 Senders and a combination of over 65,000 units.

Applications include high performance AV and signage systems in sports bars, clubs, restaurants, board and huddle rooms, command and control centers, museums, airports, classrooms, auditoriums, hotels, and retail establishments.

Sender unit features a 1U tall and half-rack-width enclosure, perfect for rack-mounting using the Gefen EXT-RACK-1U-GRY rack tray (available separately). It can also be surface-mounted or be placed on a shelf. The low-profile Receiver unit is also rack-mountable using the rack tray, and it can be surface-mounted or placed on a shelf.

When used with a Gefen EXT-RMT-EXTIRN IR extender module, Receiver unit can be hidden away behind a display or inside the equipment closet.
