This article outlines the steps involved in setting up a livestream in OBS Studio using the Revelator Dynamic, the Software Mixer built in to Universal Control and one of the Virtual Audio Outputs.
To open the mixer, open Universal Control and click on the Revelator Dynamic icon. Here you will see individual channels for each of the three Inputs on the device along with three other channels: Playback, Virtual A and Virtual B.
First, you will need to set the level for your mic.
The next step is to route the computer's system audio to the mixer in UC. To do this on Windows, click the speaker icon in the bottom right corner of the screen and select Playback L/R (Revelator Dynamic). This will send all of your computer audio to the Playback channel in the UC mixer.
On Mac, open the Sound settings in Mac System preferences and select Revelator Dynamics your audio Output device.
This will route all audio from your computer, Youtube, or game audio to the Playback channel in Universal Control.
Universal Control has three Output Mixes. Main, is a hardware-only output. This will allow you to set the levels that you will hear in your headphones or speakers connected to the Main outputs.
Next, are Stream Mix A and Stream Mix B. These are virtual outputs that allow you to route a stereo Mix of all of the Inputs to a separate application like OBS.
For this example, we will be using Stream Mix A to send audio to OBS.
Click on Stream Mix A to open the Mix. Turn up the fader for the Mic you are using and for Playback. Since we are not using the other channels currently they can be ignored or muted.
Now that the audio is routed to the Mixer and all the levels have been set in Universal Control, the last step is to set up a stream in OBS and send the audio to from Universal Control to OBS.
Open OBS and click the Plus button in the bottom right corner to create a new scene. Click this and name your scene.
Next, we will go to the Audio Mixer to set up our audio Input. By default, OBS will create two channels. One to capture desktop audio and one for a Mic/Aux Input. In this example, all audio will be routed to OBS through Stream Mix A so the Desktop Audio channel can be muted. To do this, just click on the speaker icon under this channel.
Next, click on the settings cog under the Mic/Aux channel and click Properties. This will open a new window where we can select our Audio Input device. Click the drop-down menu and select Stream Mix A L/R (Revelator Dynamic). Click Ok.
All audio from Stream Mix A will now be sent to the Mic/Aux Input in OBS.
You can now go back to the sources and add a Window or Display capture as you require and also add your camera.
If you wish to control your levels during the live stream you can use the UC surface app to control the revelator dynamic mixer without having to open Universal Control on your computer.
That's it, you are ready to stream!
