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. While smartphone compatibility allows to remote control your recorder from a
distance to achieve clearer recordings, you can link photos taken by smartphone as a visual index to the recording timeline. 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.
