The impressive DM-901 boasts enough functions and features to make it an indispensable business tool. Equipped with Wi-Fi for the first time, it enables to record in a whole new level.

Furthermore it’s made easy to download the recordings from the recorder to a smartphone to instantly share files by sending it to dropbox. Top quality recordings are guaranteed by the low-noise stereo microphone with 90° outward orientation to capture sound from all directions. The re-designed user interface offers better visibility with colour screen and graphic icons, easier operation with its scroll function, and improved usability with intuitive design.

Enhanced Usability

Our Olympus Audio Controller smartphone app enables remote control recordings via Wi-Fi, which optimizes the recording quality by allowing you to set the recorder close to the speaker. Download the recorded files from the recorder to your smartphone – to instantly share your recordings. The Olympus Audio Controller smartphone app is free of charge.

High recording quality with superb stereo feeling
The low-noise microphone boasts a 90° outward orientation, delivering stereo sound recordings with natural ambiance. In addition, the increased size of the openings around the microphone allow for higher quality recordings and playbacks.
