Meet the Roland AeroCaster: a live streaming system for multi-camera production that lets you switch between 4 devices simultaneously. It also lets you connect from up to 4 iOS and Android devices. This audio/video switching system has transition effects that enable you to switch between cameras, media, and scenes.
You can use the AeroCaster to save and recall 30 scenes with titles, graphics, and picture-in-picture windows. You can use it to stream directly to YouTube, Facebook Live, and Twitch. You can follow viewer comments in the AeroCaster Live app. The AeroCaster has two inputs for connecting XLR microphones and musical instruments.
