The XHD6420 allows playback of your favorite MP3 and WMA files recorded on CD-R and
CD-RW discs. Its powerful on-board DSP processor decodes the compressed audio while
maintaining near-CD sound quality. An internal SRAM buffer provides ESP (Electronic
Skip Protection) to virtually eliminate skipping and allows alphanumeric or direct track
search - even while a song is currently playing!
Function keys 7, 8, 9 and 0 apply to MP3/WMA operation only.
