CDR1 CD player and AM/FM receiver provides a reliable and economic background music source for a sound system. The CDR1 is a compact, integrated unit that allows users to store up to 30 radio presets (18 FM and 12 AM stations) and to play CD, CD-R, or CD-RW discs, as well as MP3 files. The CDR1 is an excellent choice for both small and large background music systems. It can stand alone on a shelf or mount easily in a standard equipment rack (2 rack spaces high, with optional rack kit).
