Here you will find HiFi sound systems and components that are best suited to the music classroom. A complete classroom sound system usually has the ability to playback CDs, MP3 files (from a USB thumb drive) as well as a dock for iOS devices (iPod/iPhone and possibly iPad) and an AUX audio input for computer and any other stereo sound source. For PA system and Live Sound (including personal voice reibforcement for teachers) see the PA and Live Sound section.
