The KanexPro SW-HDSC42D4K is a Four input and Two output multi-format seamless presentation matrix switcher with extender receiver. The matrix switcher is designed to be the central component of an AV system. It is ideal for applications where multiple signals with different resolutions must be optimized for displays. It is also suitable for presentation spaces where two displays are needed.

The matrix switcher simplifies meeting room and presentation space system integration by providing three HDMI inputs, one USB-C input, one HDMI output, and one Extender output with one HDMI loop output. It also provides one external audio input to be embedded in the first HDMI input. Additionally, it has one MIX audio input and one MIC audio input for global audio.

The matrix switcher provides true 4K scaling up to 4K@60Hz@4:4:4. Both inputs and outputs are capable of providing 4K@60Hz@4:4:4 signals. The Extender output provides an innovative solution allowing transmission of HDMI 2.0 signals over a CATx cable while ensuring original image quality. It is designed for use with the Extender Receiver. The USB-C input is ideal for AV interfacing with newer MacBooks, Chromebooks, and Windows PCs, as well as smart phones and tablets.
The matrix switcher supports auto switching on HDMI. It also allows users to control system functionality via Web GUI, RS232, IR, and CEC.

Control using IR, RS-232 or web based GUI

This 4K scaler can be controlled by any 3rd party control system, just download the RS-232 drivers to program. IR input and output control can be transmitted bi-directionally between the switcher and compatible Receiver. Front panel buttons, IR Remote, RS232 or GUI all are inclusive with a microphone input that supports phantom power and a balanced stereo audio output for audio support.


Ideal for classrooms, conference rooms, huddle rooms and other collaborative spaces where digital and analog sources need to be scaled, switched and extended over CATx in a fast and reliable manner.
