Edirol by Roland R-1 24bit Wave/MP3 Recorder

Searching for the highest recording quality in a portable device? Roland handpicked the top analog and digital components for the R-1. The unit records and plays back at crystal-clear, 24-bit audio resolution without compression. Electrolytic capacitors provide stable, reliable power to the analog circuits, eliminating DC interference and offering a truly low-distortion sound. Maximum recording time is approximately 137 minutes (MP3, 64kbps mode) when using the included 64MB memory card. The R-1 offers nine quality modes ranging from 64kbps compression to 24-bit linear WAV.

The item is probably never used, the protection foil is still on the screen. Complete with protection case, power adabter, box and manual.
