Mixxx Settings Getting Started

If you would prefer to not hear the microphone input, you can set the Microphone Monitor Mode option to Direct monitor (recording and broadcasting only). This will still mix the microphone input with your recorded and broadcasted mixes, but it will not mix the microphone with the Master output. Don’t forget to press the Talk button when using the microphone if you use this option.
Open - Preferences - Sound Hardware - Microphone Monitor Mode - Change to Direct monitor (recording and broadcasting only)

Server Connection

• Type: Select the type of streaming server you want to connect with. Shoutcast 1, Icecast 1, and Icecast 2 servers are supported.

  Mixxx works with Shoutcast 2 using the Shoutcast 1 protocol if you provide a stream name in Preferences ‣ Live Broadcasting ‣ Stream Settings. If you don’t provide a stream name, Shoutcast 2 rejects the connection (where Shoutcast 1 would accept this case).

• Host: You can enter the host as either a host name or an IP address.

• Login: As provided by your streaming server provider. Without this, you will not connect successfully to the server. The default login for Icecast is source while the default login for Shoutcast is admin.

• Mount: A mount point is a unique name identifying a particular stream. For Shoutcast it is not necessary to specify a mount point. The setting must not be blank if you are using Icecast. Try the default /mount or /live. If you haven’t been given a specific mount point you can usually make one up. It always begins with a / (slash) followed by a text without any special characters in it.

• Port: As provided by your streaming server provider. Most servers use the default port 8000.

• Password: As provided by your streaming server provider, unless you run your own radio server. It is required to establish the connection to the server and to start the broadcast.
