The DR-2d from Tascam is a portable digital audio recorder that saves files to SD cards and connects to Mac and Windows computers with a high-speed USB 2.0 connection. It features low-noise built-in stereo microphones, or you can attach an external microphone or line-level signal to its 1/8" inputs. In the event that the material you're recording gets too loud and distorts, the DR-2d features a very useful "dual recording" functionality which records and saves a second copy of the audio at a much lower level.
Musicians and people doing transcription work will appreciate the DR-2d's ability to slow down the playback of the audio, without changing the pitch. An internal metronome is included for keeping the beat, and a reverb effect is available to sweeten the sound. The DR-2d has a built-in speaker that makes monitoring your work easier, and a large, backlit LCD display makes navigation a breeze. A 2GB SD card is included, and the DR-2d is compatible with high capacity SD Cards as well.
