Powerful, portable, and simple to operate, the SR-20HD Direct Streaming AV Mixer makes it easy to manage the modern livestreaming requirements of your business or organization.
No computer is required, and everything needed to switch and stream is integrated into a single unit that anyone can use with minimal training.
When consistency, dependability, and network security are top priorities, the SR-20HD delivers professional results every time.
The SR-20HD features a gigabit ethernet port (RJ45) that enables direct streaming via a LAN.
A mobile phone with a suitable data plan can also be used as the primary streaming connection, or even as a redundant backup connection to the hard-wired LAN.
SR-20HD connects to the mobile phone via USB tethering. And through constant monitoring of network quality, the SR-20HD's Adaptive Bit-rate feature enables the SR-20HD to automatically adjust the streaming rate to reduce interruptions due to bandwidth issues.
The SR-20HD is designed to make everyone successful with livestream operation and management, regardless of experience.
It combines an easy-to-use video switcher, audio mixer, preview screen, recorder/player, and streaming encoder in one unit, simplifying the process and reducing points of failure.
Using the two HDMI inputs, you can connect common video sources such as cameras, smartphones, tablets, and computers running presentation software.
There’s also a USB video input for a Roland UVC device or compatible webcam. In addition, a wide range of audio inputs are available for mics, music players, electronic musical instruments, and more.
Once everything is plugged in, simply connect to your network router and begin livestreaming with team members, clients, or students on Facebook, YouTube Live, Twitch, or by RTMP to your CDN.
Packed with advanced Roland A/V technologies, the SR-20HD reduces the need for technical support and experienced staff members.
Automatic functions run in the background to eliminate dropped streams and help protect your organization from broadcasting inappropriate content.
And since all streaming tasks are handled within the SR-20HD, there’s no risk of malware and other issues that come with computer-based streaming on your enterprise network.
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.
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 on the same platform to reach a wider audience or create a backup for archiving or later distribution.
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.
Simplified Recording and Playback
The SR-20HD’s onboard recorder lets you capture H.264 MP4 video* to an SDXC card for later editing or uploading to YouTube or enterprise intranets.
In addition, stereo WAV audio can be captured independently for podcasts and other audio-driven media.
It’s also possible to access video clips, images, and audio files stored on the SDXC card to bring higher production values to your presentations.
