Gefen EXT-UHDKA-LANS-TX 4K Ultra HD HDMI KVM Over IP, Sender

Extend and Distribute 4K HDMI w/ HDR, USB, RS-232, IR, and 2-way audio over a Local Area Network Gefen's AV over IP solutions continue our tradition of providing high performance, scalable, expandable, and secure AV routing and distribution over a standard Gigabit Local Area Network. Our 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 our first-generation products. Each Sender and Receiver extends and routes video, USB, 2-way audio, RS-232, and IR. The EXT-UHDKA-LANS-TX & RX feature maximum input resolution of 4K 60 Hz 4:2:0, and maximum output resolution of 4K 30 Hz 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 new cutting-edge features and performance, the new 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. 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. 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.
