Used Blackmagic Design Web Presenter 4K in great cosmetic and functional condition. Minor rack casing wear from standard mounting. Front panel LCD screen, buttons, and rear connectors are clean and fully operational. 

This self-contained unit allows direct RTMP/SRT streaming up to 4K Ultra HD via Ethernet or mobile tethering without requiring a dedicated encoding computer.

Testing: Bench-tested. Verified SDI input signal, Ethernet direct streaming configuration, USB webcam video output, and HDMI monitoring feed. 

Pulled directly from a professional, climate-controlled, smoke-free corporate broadcast facility. All units have been tested, factory reset, and are running stable firmware. Expect minor cosmetic rack-wear/scuffs on the outer casing, but front panels and technical functionality are excellent.
