iTunes: About AirTunes

Whether your stereo or powered speakers are located in your living room, bedroom or basement, just plug it or them into the audio port on the AirPort Express Base Station using an audio cable. iTunes automatically detects the connection. When you open iTunes on your AirPort-equipped Mac or Wi-Fi-compliant PC, you'll see a popup list at the bottom right of the iTunes window showing your remote speakers. Select it, click play and your stereo becomes the world's greatest digital jukebox. AirTunes requires iTunes 4.6 or later.

Add Music to Your Current Network
If you already have a wireless network in place, you can use AirTunes to add music to its capabilities. Let's say you have AirPort Extreme set up in your den. There's no need to scrap this setup and create a whole new one with an AirPort Express Base Station, your DSL or cable modem, printer and stereo all in one place. Simply connect AirPort Express to your stereo in your favorite music room and plug it into an electrical outlet - it wirelessly links to your existing network, letting you play your music in your room of choice without moving anything or connecting anything else.
