Route up to four HDMI inputs to four HDMI outputs with the Key Digital KD-4x4CSK HDMI Matrix Switcher. The KD-4x4CSK supports resolutions from SD all the way up to DCI 4K, facilitating high-end multi-zone presentations of advanced digital imagery, motion pictures, and video walls. Each output can have the audio routed to a separate discrete 3.5mm analog stereo output, or digital SPDIF over RCA.
Control over this unit can be assumed through direct front panel access, IR with the included remote control, and RS-232 if part of a larger installation. The included rack ears can be used to mount the KD-4x4CSK in one standard rack space with other professional equipment. To ensure that your HDMI cables remain securely attached to the unit, eight HDMI lacing clips are also included.
