Mixer, mic, and BUTT ready to broadcast to

When starting out, a simple USB microphone is a brilliant start to the world of live broadcasting. However, as you develop your skills you'll want to introduce a mixer to allow more flexibility/granular control over your broadcasts.

One of our favourite mixers is the Behringer XENYX X1222 USB, and in this guide we'll be showing you how to connect this to using Broadcast Using This Tool (BUTT).

What you'll need:

  • A microphone with an XLR connection

  • A computer with a USB port (or a USB adapter)

  • A mixer

  • An available power supply

Before getting started, it's important to note that this is for more experienced DJ's, and can become quite complex. If starting out, we recommend using a USB microphone which does not require a mixing desk.

Setting Up the Mixer

First thing you'll want to do is ensure the mixing desk is plugged in and powered on. Once that's done, you need to connect the XLR cable from the microphone in to the mic port as shown below. You'll want to start from channel 1, and make your way along depending on how many microphones you need to connect.

Connecting the Mixer to Your Computer

Located at the back of the mixer, you'll see the USB Interface output (as seen in the image below). You'll need to connect the lead from here in to a USB port on your computer.

NOTE: Some devices (such as the Macbook Air we're using) do not have a USB port, and will therefore require an adapter.

Configuring BUTT

So that's the hardware configuration sorted. Now what you need to do is open up BUTT, and head to Settings > Audio.

On this screen, select the dropdown for 'Audio Device', and you should see USB Audio CODEC as one of the options. Please select this option.

And that's it! Now when you go live, you'll be broadcasting audio sent via the mixer.
