Roland SR-20HD Direct Streaming AV Mixer

The SR-20HD collapses a switcher, audio mixer, and streaming encoder into one desktop box that connects to the network and broadcasts on its own, with no laptop in the chain. Two HDMI inputs and a USB video-class input feed the video side, and built-in encoders push two simultaneous livestreams at up to 1080p/60. Its Adaptive Bitrate function watches the network connection and automatically eases the streaming rate when bandwidth dips, so the picture keeps moving instead of freezing.

The audio side is a genuine eight-channel mixer with up to four professional XLR microphone inputs plus line-level and headset sources, so panels, worship services, and classrooms sound as good as they look. Streams can be recorded straight to an SDXC card for archiving, editing, and later distribution. Video encodes as H.264 up to 20,000 kbps and audio as AAC LC at 48 kHz, 16-bit stereo up to 384 kbps.
