ATEN CAMLIVE PRO 4K UC3430 – 4-Input HDMI to USB-C Video Switcher, 4K@60 PGM + 4K@30 USB-C Broadcast Output

Four cameras, one stream, and you're still juggling a laptop, a capture card, and a mixer to get it on screen. The UC3430 does all three in one box. Feed four 4K@60 HDMI sources in, mix any two into a single picture, and watch the PGM loop-through at 4K@60 on your local monitor while the USB-C port pushes a 4K@30 UVC stream straight into Zoom, Teams, OBS, XSplit, YouTube, Facebook, GoToWebinar, or Twitch. The built-in audio mixer blends up to four HDMI audio tracks plus one line-level input so you can layer narration or music without a separate soundboard. Remote it from the ATEN OnAir Lite app — crop, resize, PiP, PbP, PoP, chroma key, drop in your PNG, BMP, or JPG logo, and fire transitions without touching the unit. Front-panel buttons and an RJ-45 serial port (ATEN VK) cover the rest. Rack mount kit sold separately. Runs on Windows and Mac OS X. Add to cart
