Description
For beginner to experienced livestream operator, the Roland Direct Streaming AV Mixer supports switching from up to three video inputs—two HDMI and one USB—supporting HD and computer frame rates as well as eight input audio channels, allowing you to switch and mix your live program while livestreaming two simultaneous streams. The integrated 4.3″ LCD monitor displays the input and provides vital information about your program.
The mixer supports a variety of video effects such as Picture-in-Picture, Split, Picture-by-Picture, and it supports luminance and Chroma Keying as well as Black Fade and Mix Fade transitions. In addition to the two HDMI outputs—preview and main, for monitoring and display—and the two simultaneous MP4 streams via the integrated Ethernet connector, you can record your stream to an optional SDXC media card for editing or playback later.
- USB video input is only available when streaming in Standard mode.
- Adaptive Bitrate
- The SR-20HD’s unique Adaptive Bitrate function monitors the quality of the network connection and automatically adjusts the streaming rate to reduce interruptions due to bandwidth issues.
- Mobile Phone Tethering
- A mobile phone with a 4G or 5G data plan can be used as the primary streaming connection or a redundant backup. Should anything happen to your main hardwired network connection, the SR-20HD will automatically switch to the tethered mobile phone over USB.
- Safety Delay
- With the SR-20HD, you can confidently stream unscripted events and prevent offensive content from being broadcast to your audience. The Safety Delay function buffers up to 60 seconds of video and audio, allowing you switch to a still image or mute the sound if anything goes wrong.
- Dual Streaming Destinations
- Encode and broadcast livestreams to two independent channels at once to reach a wider audience or create a backup for archiving or later distribution.
- Panel Lock
- Panel Lock prevents users from accidentally changing settings that could disrupt a broadcast. You can disable access to a wide range of hardware controls and menu parameters on an individual basis, leaving only the essential functions needed for the livestream.
- Video Auto Switching
- Change video input sources at predetermined time intervals to make your presentation more dynamic.
- Auto Mixing
- The Auto Mixing function ensures that the mix between your connected microphones remains balanced. You can set specific inputs to take priority when someone starts to speak, and other audio levels are automatically reduced as needed.
- Follow the Source
- The SR-20HD makes it simple to broadcast with multiple presenters. With the Audio Follows Video function, the corresponding audio automatically follows when you switch to a different video source. Conversely, the Video Follows Audio function switches video based on who’s currently speaking.
- Note: The SR-20HD’s USB video input and SDXC card functions are disabled in High-Quality mode.
