Highest Quality Recording

48KHZ/16BIT Linear PCM Recording

Three different recording formats can be chosen to record and playback with the DM-901: The linear PCM format employs a sampling rate of 48 kHz to surpass even CD-quality audio; extreme versatility is guaranteed by recording in MP3 format; and WMA format combines high quality in a more compact size file.

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.

A Dragon NaturallySpeaking “5 Dragon” Rating

A Rich Array Of Playback Functions

Write Meeting Minutes Efficiently With Voice Playback

By using the Voice Playback function, the recorder skips the non-voice, dead air parts of the recording and only plays back parts 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 more efficient transcription of your recordings.

Voice Balancer

When recording meetings in large rooms, the recording levels of each sound tends 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.

Recording Hours And Battery Life

The DM-901 offers 850 hours of recording time and an impressive 29 hours of battery life.


Two-Inch Large Color LCD

The high definition two-inch color LCD provides greater resolution and contrast ratio than the average black and white display of conventional voice recorders, and the visibility of the screen is much clearer. Also, the color-coded information has improved the visibility and functionality.

Scene-Select For Fail-Safe Recording

By simply selecting from the recording menu, you can set the optimum recording settings according to the scenes. Anyone can easily make fail-proof, high-quality recordings, even in a situation requiring quick response. The DM-901 also has a dedicated function button, making it even easier and quicker to select a scene.
