Cue Acoustics Cue Radio Model R1, White Apple Universal Dock: The dock on the Model r1 charges and plays most generations of iPod and iPhone. It is fully integrated into the design of the r1 - not a separate unit or an add-on like some other brands offer Advanced Digital Technology: The D2Audio DSP (digital signal processing) chip and digital amplifier in the Model r1 provide amazingly clear sound and a very wide dynamic range. As a result, you will hear subtle details in all your favorite music that can be obscured by lesser quality sound systems Dual Alarms: The Model r1's two completely independent alarm clocks are very flexible and reliable. A backup battery ensures that your alarm settings will remain intact through a temporary power outage Scrub Forward and Rewind with Navigation Dial: The navigation dial also functions as a scrub wheel in iPod mode - allowing you to rewind music by turning it counterclockwise and advance forward by turning it clockwise Multi-functional Graphic Display: The r1's 3" LCD display makes any action easy and intuitive. It integrates gracefully with your iPod or iPhone, with all menus available on either the iPod/iPhone display or the r1's display
