MP-SC-21 is a professional 4K Scaler Switcher that scales HDMI/VGA video signal to an HDBaseT output by selecting output resolution from 720p to 4K via OSD. The HDBaseT output supports bidirectional PoH and can connect to HDBaseT receiver up to a maximum of 70 meters (230 ft) (HDBaseT receiver sold separately). With 1 IR In and 1 IR Out and 1 RS232, the IR and RS232 control signals can be transmitted bi directionally between the MP-SC-21 and a compatible HDBaseT receiver. It supports advanced built in EDID management and is HDCP 2.2 compliant. Video and audio sources can be selected via front panel button, table grommets or RS232 commands by 3rd Party control device. Moreover, it features volume buttons to turn up/down the volume level.
