Roland SR-20HD Direct Streaming AV Mixer

If you are looking to run a livestream without being inhibited by a PC, this mixer is for you! Stream directly, securely, and portably with the SR-20HD.

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.

- Built for Success:
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.

- Plug in and Stream:
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.

- Secure and Reliable Operation:
Packed with advanced Roland A/V technologies, the SR-20HD reduces the need for technical support and experienced staff members. Automatic read more 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.

- 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.
