The Marantz CDR-310 is a 2-channel portable CD-R field recorder featuring MP3 and MPEG compressed or uncompressed WAV and AIFF recording in either stereo or mono modes. The simplified, intuitive design allows for use in government agencies, law enforcement, boardroom meeting documentation and broadcast applications.

The lightweight and versatile CDR-310 is equipped with professional features such as XLR microphone inputs with 48V phantom power, a set of S/PDIF digital I/Os, pre-record buffering and background recording modes while stopped or in pause mode, and ample long-term recording in the compressed modes. After storing audio temporarily on the internal 1", 4GB hard drive, the unit will record both audio and data to CD-R discs.
