Radio server represents your radio. Broadcasters can have several radio servers in their account to manage several stations. Each radio server has its own music library, channels, settings, etc. There is a server switch dropdown at the top of every broadcaster account interface (next to start/stop buttons), new servers are created using this dropdown as well.
Channel is a streaming endpoint of your radio server. Radio channel is a Shoutcast/Icecast instance that broadcasts your music according to your setup. Radio server can have several radio channels that stream simultaneously the same content. Channels can have different format (mp3/aac/flac/etc), different bitrate, listeners limit and other settings.
Playlist allow you to organize/split your music into several playlists that you can later use in the scheduler. For example, you can have several playlist like "morning", "day", "night" and use scheduler to play them according to the daytime.
Scheduler allows you to arrange playlists playback according to the time of the day. You can choose some playlist to play in the morning, other in the evening, etc. Scheduler has "events", each event can happen once or recurring by the day of the week.
Djs section allow you to manage your live Djs. By default all radio servers have only one DJ - that's "auto" DJ that broadcast the music that you upload to the server. If you want to broadcast live - you create a "live" DJ in this section and the system generates connection settings for remote connection that you can later use in your broadcasting software (Sam Broadcaster, BUTT, RadioBoss, etc) to stream live.
Allows you to broadcast other radio station streams. You can make your scheduler stream another radio on specific dates and time like you do with the playlists.
Jingles are any types of music or voice drops or ads you can insert into your stream. It’s possible to arrange jingles into groups - to split them by categories and blocks to make a sequence of jingles and tracks play at once.
This is where you manage your radio station settings, passwords, email and language etc.
This section depends on your license and provides information on the current account limits and billing info.
Widgets are special pieces of HTML code you can copy to your website to have players, listen links, current track info, listener requests, etc. Most of the widgets are customizable.
