“TRESMIC” Three-microphone system for superior sound
The DM-720 features a three microphone system that includes both directional and omnidirectional microphones to faithfully capture the depth and fullness of the sounds recorded. This Tresmic combination provides a wide frequency range for the most demanding professionals.
Using the latest technologies, zoom microphone unleashes the power of proximity in noisy environments or when recording from a distant position. The zoom microphone allows you to expand and contract the microphone range by adjusting the direction with the "+" and "-" buttons on the recorder.
Create high quality recordings using linear PCM format. While this feature may exceed everyday business needs, when selecting this bit rate and sampling frequency, users can readily make CDs of their own recordings.
The Intelligent Auto Mode function automatically adjusts the microphone sensitivity according to the input level. This function makes it easy for users by automatically adjusting the microphone sensitivity according to the volume of the speaker.
The low-cut filter is used to eliminate sound at frequencies lower than 300 Hz during the recording process. By cutting the lower frequency sounds during recording your audio is free of background noise and distortion during playback.
The Voice Playback function allows you to skip non-voice parts during playback, and only play the parts of the file where there is vocal content. Voice Playback saves time and improves efficiency during transcription.
The Voice Balancer function works during playback, the volume of recorded voices is adjusted to make dialogue easier to hear. When voices are at different volume levels due to the distance and physical relationship to the recorder, the Voice Balancer automatically makes smaller voices louder, and ensures that louder voices stay below a given level, providing playback where everyone is audible.
The noise cancellation function powerfully reduces unwanted ambient sounds such as air conditioner noise or projector fan noise to enable clear playback quality.
Transcription mode comes in handy when creating minutes from recordings. While transcribing, users frequently repeat play, and stop to check the text. In Transcription Mode, the recorder will automatically playback the 3 seconds before the stop, so you can check the contents before proceeding. On the other hand, fast forward is preset to 3.5x so you can skip the silence in your recording.
Speech shadowing is an effective technique to learn foreign language by repeating the subject right after hearing it. This mode helps you learn languages by having the audio playback, and then silently playback repeatedly, so you can easily practice speech.
The DM-720 can connect directly to your PC via the built-in USB connector. This makes it possible to save data anytime, anywhere. Not only can you save and share data, but the DM-720 can also be charged via USB.

The voice guidance feature provides audio announcements of the recorders operations in an easy to understand spoken voice. For further ease-of-use, the buttons are designed so the recorder can be maneuvered without looking at the display.
Large audio files can be divided on the recorder without the use of a PC. Split and divide files, by topic or size for easy file management.
