The Logitech UHD 4K/USB Rally Display Hub is central to the Rally Plus Video Conferencing system and connects all the components together, such as the camera, speakers, and mics, via USB to an HDMI display. The speakers connect to the Display Hub via mini-XLRs and it powers up two Rally speakers to provide rich sound, even in larger rooms. It connects to the Table Hub via RJ45, via HDMI to up to a UHD 4K display, to the Rally Camera via USB Type-C, and it connects to the meeting room computer via the USB Type-B connector.
