The Olympus 720 PRO is an entry level portable meeting voice recorder, recommended for 1 on 1 meetings and short table conferences and small room depositions.

This recording device for meetings has 4GB of internal memory and features the Variable Control Voice Actuator, which triggers recording by voice or sound rather than the push of a button. If 4GB of memory isn't enough, the DM-720 has a micro SD card slot, which can expand the memory capacity another 32GB.


Olympus digital recorders that court reporters use do not have the ability to run on Ac adapters anymore.


The tresmic 3 microphone consists of a Stereo Directional mic and Center Omni Directional mic, which allows you to capture lower bass ranges with impressive clarity. Also, a 3.5mm (1/8") microphone jack lets you plug in an external mic, extending the pickup for use on larger tables. 

When selecting a digital meeting recorder for windows, always ask about the compatibility. The Olympus DM720 is compatible with Windows XP, Vista, 7 & 8.

This is a good piece of meeting recording equipment for new users and people on a budget.

Product Description


The top of the class DM-720 includes high quality recording features packed into an efficient, smart metal body.  It’s equipped with an easy-to-use interface, extended editing operations and various playback functions.  The DM-720 provides outstanding practicality and reliability to support your recording needs.


High-quality recording


“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.


Voice Balance delivers audio quality that is easier to hear


The Voice Balance 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 Balance 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.


Direct PC connection without a cable


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.  All operations of recording, saving, sharing, and charging can be performed on this single, smart and easy-to-use voice recorder.




microSD card slot add extra memory cards


The DM-720 includes a micro SD card slot that supports cards up to 32 GB in size. You can select whether to use the 4GB of built-in memory or a micro SD card from the recorder menu.
