The acclaimed Wave music system still sets the standard for quality audio and ease of use among one-piece, table top stereos. No wonder so many people use it as their main home entertainment system. And you'll enjoy extra hours of uninterrupted CD music with the Wave music system multi-CD changer included in this package. Simplicity by Design The Wave music system was engineered for easy enjoyment right out of the box. No setup required: just plug it in and you're ready to go. The FM/AM radio and CD player are built in. There's an auxiliary input for your MP3 or other portable player, and a headphone jack for keeping the music to yourself. The system's sleek appearance is uninterrupted by buttons, with all controls on a handy, slim remote. The large display panel is brightly lit and easy to read, prominently displaying the artist, title and album names of your MP3 CDs. The Wave music system with multi-CD changer package lets you enjoy extra hours of uninterrupted CD music. Simply slide one CD or MP3 CD into the slot on the front of the Wave music system, and up to three more into the add-on multi-CD changer. One remote controls all CD functions, plus FM/AM digital tuner, clock and alarm. A spare remote is also included. The changer has the same small footprint as the Bose Wave music system. Together they stand less than seven inches tall and can fit almost anywhere, unlike most conventional bookshelf stereos. The CD changer also provides an additional connection for another audio source, such as an iPod or DVD player. Unique Bose innovations account for this compact system's hearty sound. Proprietary waveguide speaker technology delivers performance well beyond the speakers' size. Two 26-inch folded waveguides are precisely tuned to amplify the output from speakers to reproduce lifelike sound from a small enclosure. You'll hear full-bodied sound, especially in lower registers, for more natural-sounding bass and percussion instruments.
