Designed with serious music fans in mind, the Sony D-NE330BLK Psyc CD Walkman lets you listen to your favorite CDs, MP3s, and ATRAC recordings in style. The sleek portable player is ideal for listeners who already have extensive music libraries, as it comes with bundled software (SonicStage 2.3) to burn and play back everything from MP3 to ATRAC3 and ATRAC3plus tracks. The latter is an advanced audio compression technology offering multiple bit rates, allowing you to create music compilations tailored to your listening preference. More significantly, a single CD-R/RW disc can store up to 490 ATRAC3plus selections when burned at 48 kbps, thus saving money, time, and storage space. And if you"re just starting your digital music collection, don"t fret, as the Psyc is compatible with Sony"s Connect Music store and its vast online music archives. The Psyc offers a wide array of playback modes (18 in all), ranging from repeat and random play to track programming to bookmarking. The five-direction control key, meanwhile, makes navigation a breeze. The Psyc is slouch from an audio perspective, either, with such features as a parametric equalizer that lets the user set not only the amount (in dB) by which a certain frequency band is boost or cut, but also the width and/or center frequency of the band; Digital Mega Basss sound, which employs digital processing technology to produce rich, deep bass tones with extremely low harmonic distortion; and a two-position Automatic Volume Limiter System (AVLS) that maintains the volume output at levels below the distortion threshold for cleaner sound reproduction. Best of all for joggers and other active users, the Psyc offers Sony"s skip-free G-Protection technology, which ensures quick recovery from horizontal and vertical shock. Other details include a slick black housing, an easy-to-read three-line LCD, multilingual support for LCD text, ID3 tagging, a set of earbud headphones, and an auto-shutoff feature to conserve battery life. The Psyc, which runs for up to 41 hours on a single AA battery (not included), measures 5.42 inches in diameter and 1.22 inches tall and is backed by a 90-day warranty on parts and labor.
