Outputting Video/Audio to a Computer for Streaming
Here’s how the video and audio mixed by the VR-120HD can be output to a connected computer. You can also input audio that’s played back by the
computer.
By using an internet-connected computer with streaming app, you can distribute content as a live internet stream.
In order for the audio and video from the VR-120HD to be correctly viewed on the computer, app that supports the USB video class and USB audio class
must be installed on the computer.
* For the latest operating requirements, refer to the Roland website ( https://proav.roland.com/ ).
