Roland SR-20HD Direct Streaming AV Mixer

For beginner to experienced Livestream operators, the Roland SR-20HD 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 live-streaming 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, and 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.

The SR-20HD is suitable for users with varying levels of experience, from beginner to experienced, as 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.

If you need to connect more sources, you can expand your possibilities with a Roland USB video class (UVC) device. A variety of Roland A/V products are supported, allowing you to send high-quality, uncompressed video and audio to the SR-20HD's USB video input. Some USB webcams and other third-party devices that support uncompressed UVC output may also be compatible.

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 is available for mics, music players, electronic musical instruments, and more. Once everything is plugged in, simply connect to your network router and begin live streaming 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 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.

The SR-20HD covers the divergent audio needs of single presenters, conference panels, and even musical performances. Inputs for up to four professional XLR microphones, line-level signals, and a headset mic provide multiple ways to connect all common analog sources. You can also mix in digital audio from HDMI and USB sources, plus audio from videos and music files stored on an SDXC card. Make quick volume level adjustments for individual sources using the dedicated faders and knobs, and go deeper with EQ and dynamics processing via the preview display and F1-F4 encoders. You also have five user-assignable function buttons to speed up your workflow, providing quick access to Auto Mixing, audio/video playback, F1-F4 functions, and more.

With a variety of powerful tools, you can automate video switching and audio mixing tasks to ease your workload. This is particularly helpful when you're also a presenter, allowing you to stay focused on delivering your message to the audience.

With Scenes in the SR-20HD, it's easy to bring pro production values to your live streams by executing complex switching functions, all at once. Setup and store five preset arrangements of layered sources and display them in customizable inset windows. Then, use the dedicated Scene buttons to switch between them and keep the audience engaged during the broadcast.

The SR-20HD's Standard mode supports 1080p resolution at 30 FPS, which provides excellent quality for most live streaming applications. But if you're broadcasting live sports or other events with a quick movement, you can select High-Quality mode to increase the frame rate to 60 FPS and reduce motion blur.
