Tivoli Music System BT HiFi System - Black lay music wirelessly through the Music System up to 9 meters (30') away with a class leading reception range. The Music System BT Black/Silver uses Bluetooth 2.1 + EDR wireless technology's advanced A2DP profile for high-quality audio. Frequency Hopping Spread Spectrum (FHSS) allows the mini shelf system to skip between the radio range resulting in low-to-no noise interference with other wireless devices. A Slot-load CD Player sits just above the display and plays CD/CD-R/CD-RW/CD Text/MP3/WMA discs. Feature-rich yet easy to use, you can skip between tracks from the included full-functions remote or buttons located on the face of the shelf audio system. Wake to dual, independent alarms each with its own snooze function. You can choose to rouse yourself with music or chimes. Change the brightness of the displays backlight, brighter for the day or balanced for limiting sleep disturbance. Integrated, Down-Firing Powered Subwoofer pumps out bass from the mini cabinet sounding like a full size speaker. Does your audio device not have Bluetooth? Not a problem with an rear facing auxiliary input. Listen privately with front panel stereo headphone output.
