Get Wireless Music Anywhere in Your Home with AirPlay
Cut the cords and rock your iTunes from any room in the house.
There’s another way to make sure your music’s wherever you are in your house: go wireless with AirPlay. Formerly known as AirTunes, AirPlay lets you set up iTunes to stream your music library throughout a home network using a $99 AirPort Express.
1. AirPort, Meet Speakers
Connect your AirPort Express to your receiver or powered speakers using cables like Apple’s $39 AirPort Express Stereo Connection Kit, which gives you the choice of either stereo RCA (analog) or optical Toslink (digital) connections. You can also install additional audio hardware or stream to an Apple TV for multi-room audio. The new black Apple TV can also stream video.

Apple’s AirPort Express Stereo Connection Kit connects your speakers to your AirPort.
2. Join the Network

Sign in here, AirPort Express.
Add the AirPort Express to your home network with AirPort Utility (under Applications > Utilities). Name the Express whatever you’d like and assign a password; for AirPlay, select “Join a wireless network” on the second and third screens, then select your network. A minute or so later, you’ll be ready to rock.
3. Configure iTunes
From iTunes 10.1 or later, click the AirPlay icon in the lower-right corner of the window (if it’s not there, turn it on by clicking the checkbox at iTunes > Preferences > Devices). Then just select the device you want to send your audio to. A TV screen icon indicates a video-capable device (like the new Apple TV); a speaker icon designates audio only. Choose Multiple Speakers to send music to several devices simultaneously. You can control the volume for each one with a slider.

This pop-up lets you choose where iTunes sends your music.
