Sound is picked up by the DR-05's pair of built-in stereo condensor microphones, which are omnidirectional. These microphones have a sensitivity of up to 125dB SPL. Once recorded, you can save your audio using the microSD and microSDHC card slots (a 2GB microSD card comes included). This model is a step down from the higher cost DR-07MKII in that the DR-07MKII is equipped with adjustable microphones, a reverb effect, Overdub recording mode, and Auto Record/Auto Mark functions that the DR-05 model lacks.
