Roland - SR-20HD Direct Streaming AV Mixer
Introducing the Roland SR-20HD, a live streaming AV mixer designed for broadcasting without a computer. This compact control unit manages your cameras and microphones while sending your stream directly to YouTube or Twitch. It's the perfect tool for securing your live broadcasts thanks to its simultaneous recording on SD card. Enjoy a simple, reliable solution for professional live broadcasts in the blink of an eye.
Presentation
For businesses, associations or video podcast creators, the real relief comes in the form of stability. Because there's no external software to manage, you avoid update bugs or processor overheating in the middle of a live broadcast. The device even incorporates an ingenious safety feature: if your main internet connection fails, you can plug your smartphone into USB to use its 4G or 5G network as a backup. It's the kind of detail that saves a conference or important event when the building's network decides to let you down.
When it comes to audio, Roland hasn't done things by halves. There are four inputs for connecting real professional microphones, guaranteeing sound clarity far superior to that of a conventional webcam. The mixer even has automatic functions that lower the volume of the music as soon as someone speaks. You concentrate on your message, and the machine takes care of smoothing out the rendition so that the audience hears every word effortlessly.
What's more, it's highly visual thanks to its built-in screen. You can prepare 'scenes', pre-set configurations that allow you to switch from a wide shot to a Powerpoint presentation at the touch of a button. If you're worried about unforeseen live events, a safety function can even delay the broadcast by a few seconds, giving you time to cut the sound or image in the event of a minor incident on the set. It's a reassuring tool that supports your growing skills without ever losing you in complex menus.
The SR-20HD doesn't just broadcast, it archives. By slipping an SD card into the device, you can record your performance in high quality. This is ideal for reworking a video at a later date, or for keeping a clean record of an event if the internet feed has suffered micro-cuts. All in all, you end up with a light, comprehensive travel companion that simplifies the technical side of things, leaving plenty of room for your creativity and your exchanges with your audience.

Another crucial point for the security of your live streams is Adaptive Bitrate. The console monitors your connection in real time and automatically adjusts the bit rate of the stream to prevent the image from freezing if the bandwidth drops. And what if the wired network goes down completely? The USB 'Control' port enables USB tethering: plug in your 4G or 5G smartphone, and the SR-20HD switches to your mobile connection to keep the live stream going, whatever the cost.
For those managing unpredictable events, Safety Delay is a real lifeline. By creating a safety buffer of up to 60 seconds, you're in complete control: if something happens on set, you have time to switch to a still image or mute the sound before it reaches the audience. It's these kinds of details, like the EDID emulator that forces the right resolution onto your HDMI sources, that make the SR-20HD a war machine for live broadcasting, far from a simple streaming gadget.
