The Noise Cancellation feature blocks out unnecessary background noises that can sometimes overwhelm a recording. Scene Select mode helps optimize recording quality with preset environmental settings that correspond to common surrounding conditions. The DM-620 combats unwanted environmental sound with a litany of menu options like scene select, noise cancellation, zoom microphone and low-cut filter. Settings like crowded press conferences, jam-packed courthouses and large lecture halls can produce unwanted background noise that may compromise an audio recording. Those with visual or learning disabilities have long been faithful Olympus users, and the DM-620, like its DM-series predecessors, was built with assistive needs in mind. Languages can be set to English, French, Spanish and Portuguese. This optional function helps the user operate the device without the need to see the menus or buttons. Combined with more than 1,000 hours of consecutive recording capacity, the DM-620 doesn't miss a beat.Ī key feature of the DM-620 is complete voice guidance functionality: the recorder can provide audio prompts for users with assistive needs. Sensitive microphones are of utmost importance to capture the nuances of every note, word or sound regardless of frequency. The DM-620's TRESMIC system employs two condenser stereo mics and a center, omni-directional mic capable of capturing lower bass ranges down to 20Hz.
