Simplicity with sophistication: the Key Digital® KD-4x1WUTx wall-plate/desktop switcher/extender

— The flagship of the comprehensive family of user-friendly 4K wall or desktop box-mount switcher/extender solutions from Key Digital® is the KD-4x1WUTx 4x1 three-gang switcher/ transmitter which provides dual HDMI, Display Port and USB-C inputs, HDBaseT signal and control extension (that includes displays and other external devices) with programming-free installation —


ISE, Barcelona, January 31, 2023 – Addressing the need for convenient AV switching at the source in conference-room, boardroom, event-space, lecture-room and training-room applications, the Key Digital® Unified Communication and Collaboration solutions family includes a range of three-, two- and single-gang wall-plate/desktop box-mount switcher/transmitters. These products provide a flexible range of AV and USB 2.0 connection options, local and remote control, CEC display control and signal extension via HDBaseT/Ethernet. Installation requires zero programming (saving precious time in the field), and operation is user-friendly for the entire line.


At the top of the line is the KD-X4x1WUTx, a 4x1 4K/18G Wall Plate Switcher featuring front-panel dual HDMI, Display Port and USB-C inputs. The KD-X4x1WUTx supports Ultra HD/4K up to 4096x2160 at 4:4:4 (signals up to 18 Gbps bandwidth) for no-compromise video performance. Its HDBaseT output natively integrates with Key Digital’s KD-X100MRx black box HDBaseT Receiver or the KD-UPS52U Presentation Switcher, either of which will provide the switcher/extender Power over HDBaseT (PoH) – that means the only rear-panel connection required is a RJ45 jack paired with a single CAT5e/6 Ethernet cable for power, signals and IP control. The HDBaseT output can drive 100 meters of cable at full resolution.


The KD-X4x1WUTx fits in a standard three-gang box for wall, podium or table-top AV box mounting. Inputs can be switched manually with front-panel buttons, and, with auto-sensing enabled, the KD-4x1WUTx will automatically switch to a newly connected source or away from a disconnected source.


“The KD-X4x1WUTx is not merely a switcher,” shares DeWayne Rains, Key Digital VP of Sales. “Beyond input selection and source extension, USB cameras and mics, audio DSP and keyboard/mouse/touchscreen extension are accommodated by front panel USB host and device ports that are soft-codec-enabled to create a connectivity hub that provides unparalleled functionality in a wide variety of applications. This one compact device delivers the connectivity needed while also replacing a host of ancillary devices that would typically be required for a complete solution.” Connected computers interface with extended devices by way of USB host and device ports on compatible receiver units or by way of device ports on the KD-UPS52U Presentation Switcher.


The KD-X4x1WUTx further simplifies system operation by including centralized control of displays and projectors – power, volume and muting – through the integration of Key Digital’s CEC Manager™ control (no additional wiring is required) and through the free KD App. The KD App will scan the network and auto-populate pre-built GUIs for connected device management – not just projectors and displays, but all KD App-ready Key Digital devices sharing the network. Complete configurations can be realized with no programming by way of the free Key Digital Management Software™ Pro app for Windows computers.


The KD-X4x1WUTx additionally handles a host of protocols and interfaces, including fully licensed HDCP 2.2, TMDS re-clocking and signal regeneration, EDID handshake and management, bi-directional RS-232 and TCP/IP control with simplistic open API and IR remote sensing. Surround audio up to 7.1 Dolby® and DTS™ is supported with local de-embedding for 2 channel signals.


The KD-X4x1WUTx has an MSRP of $1,288 (USD). The full family of Key Digital cost effective, high-performance Wall Plate Switchers includes additional models that feature identical video resolution capabilities but are configured for differing sets of input formats. All are available immediately, shipping from stock.
