Description
This 4K60 2x1 Multiviewer Seamless UHD Video Switcher was developed to support higher output resolution (4K@60) for multiple sources on a single screen. It can combine two video signals onto a single UHD or HD display. Users can manage each input and create combinations of the two inputs on a single display, as well as adjust the position of either input. It supports 4 display modes, allowing users to freely switch 2-channel HD input signals for single screen or multiview display. Audio RCA/Optical de-embedding is supported for external audio distribution systems. The device can be controlled via front panel buttons, IR remote, OSD menu navigation, Controller software, and RS-232 commands.
