“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. Two microphones are arranged at a 90° angle to produce a natural stereo experience, with an independent central microphone to capture lower bass frequencies and deliver premium sound. This Tresmic combination provides a wide frequency range for the most demanding professionals.
Zoom microphone for recording from a distance
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.
Compact recorder with 48 kHz/ 16 bit linear PCM recording
Create high quality recordings using linear PCM format. With a sampling frequency of 48 kHz, the PCM format easily surpasses CD-quality audio. 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.
Automatic sensitivity adjustment with Intelligent Auto Mode
The Intelligent Auto Mode function automatically adjusts the microphone sensitivity according to the input level. To set this function, simply select 'Auto' for the recording level from the menu. This function makes it easy for users by automatically adjusting the microphone sensitivity according to the volume of the speaker. Let Intelligent Auto Mode keep your recordings consistent, by not having speakers too quiet or too loud.
Low-cut filter eliminates extraneous noise
The low-cut filter is used to eliminate sound at frequencies lower than 300 Hz during the recording process. Some examples of low frequency sounds include air conditioner noise, projector fans, and heavy winds. By cutting the lower frequency sounds during recording your audio is free of background noise and distortion during playback.
Create meeting minutes efficiently with Voice 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.
Voice Balancer delivers audio quality that is easier to hear
The Voice Balancer function works during playback, the volume of recorded voices is adjusted to make dialogue easier to hear. This feature works great in combination with the Intelligent Auto Mode which is used to ensure recording quality. 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. This comes in handy when recording sound sources from many positions, such as in a large meeting or conference. The voice filter function operates simultaneously, and reduces the prominent noise produced when amplifying small sounds. By eliminating the lower and higher frequencies during playback, recorded voice is further enhanced.
Noise cancellation for clear playback quality
The noise cancellation function powerfully reduces unwanted ambient sounds such as air conditioner noise or projector fan noise to enable clear playback quality. This function is effective during playing back.
Create meeting minutes efficiently with "Transcription mode"
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.
Effective language learning through Speech Shadowing
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. Simply identify the speech to be played back repetitively by indicating the position in the file where it starts and stops.

Voice guidance and other usability improvements
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.
The File Divide function makes it easier to handle longer recordings
