Roland SR-20HD audio mixer Black

Roland SR-20HD Direct Streaming AV Mixer

The compact SR-20HD makes it easy to produce content and encode livestreams without a computer: connect AV devices and stream securely to multiple platforms over LAN, such as Facebook, YouTube Live, Twitch or any CDN via RTMP, while recording to SDXC media for archiving and later distribution. Dual streaming encoders, simple video switching, audio mixing and recording are combined in one portable unit that anyone can operate with minimal training, and since all streaming runs inside the unit there is no risk of computer malware on the network.

Two HDMI inputs take cameras, smartphones, tablets and computers, and a USB video class input and a range of audio inputs for mics, music players and instruments are also available. The Adaptive Bitrate function adjusts the streaming rate to the network quality, a 4G/5G phone tethered via USB can serve as main or backup connection, and Safety Delay buffers up to 60 seconds so a still image or mute can be applied if something goes wrong. Scene functions, auto switching and auto mixing simplify operation, and sound effects, stills and video can be played from the SDXC card.
