Sony CDX757MX MP3 10-DISC CD Changer

The CDX-757MX is equipped with 8X oversampling: a digital filter that uses multiple sample calculations to provide a closer representation the original analog signal for better sound quality. There's also a 1-bit D/A (digital-to-analog) converter, and Active Servo Control, which monitors functions like optical tracking and focus then actively adjusts those functions in real time for optimal audio performance.

There's also a handy, 110-CD custom file memory, which provides intuitive and safe source management for an audio and A/V system such as disc memo, station memo, and memo list, as well as the usual disc, track, and artist information that comes encoded directly on your CDs. (Both playback and media components must have CD Text compatibility.) For those bumpy road situations, Sony has built in a mighty 12-second advanced electronic shock protection system, in which an electronic circuit stores the audio data stream from your disc in a memory buffer. Additionally, the shock isolation system uses silicon-filled shock absorbers for increased protection of your player and continuous music.

The player will accept any Sony remote control, and comes with a 5-step adjustable mount angle, the compact cabinet itself, and the 10-disc magazine.
