One end sits in the studio and feeds your desk. The other end is whoever you are talking to, wherever they are. Here is the whole setup.
On the studio machine or a tablet, open the app. Allow the microphone when the browser asks — that is how the audio gets in and out.
Pick the sound card or interface the desk is wired to, set the gain, and choose how much processing you want holding the level steady.
Feed the chosen output into a spare channel on your mixer. That channel is now your down the line source, metered on screen as well.
Your device shows its own code. Save your regular reporters as Quick Connect buttons so you can call them with one tap next time.
No download and no account. The address opens the join screen and asks to use the microphone.
Six digits from the studio, or just tap the invite link they messaged you.
Talk normally and watch the meter. Adjust the gain so it sits in the middle, and put headphones on to stop feedback.
When the bar turns green you are linked at broadcast quality. The studio hears you and can talk back.
