Next Generation Digital Voice Recorder
The new DM-901 unites premium sound quality with new mobile features for easy note-taking in any situation. For the first time on an Olympus recorder, Wi-Fi links the DM-901 to a user's Smartphone, from which an available app can remotely trigger the DM-901 to record on command. This feature is ideal for capturing events when there is a significant distance between the user and the speaker.
Remote Control by Smartphone
At events such as seminars and lectures where there is distance from the speaker, you can still achieve the clearest recordings. Set the recorder close to the speaker and use the available app to control the recorder from a distance You can start and stop the recording from a distance so you only capture the content you need. Recorded files and visual indexes linked to the files can be easily uploaded to Dropbox through a Smartphone and accessed with a web browser.
Use Photos From Your Smartphone as a Visual Index
Images taken by your Smartphone's camera during recording can be used as a visual index by linking them to the timeline. The visual index makes it easier for you to search or manage your recording than relying simply on audio and text.
The Zoom Microphone Mode Makes It Possible to Focus on a Voice That is Far Away
The latest directivity control technology has been used to make it possible to switch direction with the "+" and "-" buttons. It provides value by zooming in on audio sources when recording a discussion or lecture from a distant position or when recording in an environment in which there is a lot of ambient sound. The new zoom microphone mode adjusts the recording level higher according to the zoom.
Recording Hours and Battery Life
The DM-901 offers 850 hours of recording time and an impressive 29 hours of battery life.
Write Meeting Minutes Efficiently with Voice Playback
By using the Voice Playback function, the recorder skips the non-voice and dead air parts of the recording and only plays back where there is sound. For example, if 70% of the recording is conversation, a one-hour recording can be shortened to approximately. 40 minutes. This allows you to more efficiently transcribe your recording into meeting minutes.
When recording meetings in large rooms, the recording levels of each sound tend to vary due to different distances and positional relationships with respect to sound sources. Even in these cases, the Voice Balancer function adjusts the volume levels of all speakers to a certain level so that it is more clear to hear.
Noise Cancellation for Clear Playback Quality
The noise-cancellation function powerfully reduces unwanted ambient noise such as air-conditioner noise or projector fan noise and enables clear playback quality. The function is very effective when playing back meeting recordings.
The voice guidance feature can read out the names of menu items on the screen so you can operate with confidence by touch alone.
Enhanced Screen and User Interface
The DM-901 offers a high definition 2" color LCD which perfectly showcases the new user interface. Olymp
