Media Xpander
Alpine's Media Xpander restores musical life to MP3 files, FM radio, satellite radio, and CD/DVD discs. It "opens up" the sound (through expansion) and improves clarity (by restoring attenuated frequencies) without altering the tone, so your entertainment is more entertaining! The MediaXpander uses Digital Signal Processing to analyze fundamental frequencies, then calculate and generate the missing harmonics and frequencies lost to compression. The result is a richer, more "live" sound. There are three selectable expansion modes (plus an "Off" position), so you can choose the setting that sounds best to you. (Media Xpander-equipped receivers will even remember each source's settings.) MediaXpander is not a glorified loudness button; it's a great-sounding processor that will add to your enjoyment of the music.
