"TRESMIC" Three-microphone system for superior sound

The DM-720 achieves high S/N ratio thanks to its low-noise microphone design. The stereo microphones arranged outward at an angle of 90° produce a natural stereo feeling, while an omnidirectional centre microphone compensates for low-range sounds. By increasing the size of peripheral openings and capturing sound from both front and rear, the resultant phase difference can be used to maximise directional microphone characteristics. When the omnidirectional centre microphone is on, frequencies from 20Hz to 20kHz are picked up (60Hz to 20kHz when off), compensating for low-range sounds.

Zoom microphone for recording from a distance

With the latest directional quality control technologies, switching to directional microphone mode unleashes the power of proximity recording in noisy environments, such as at lectures or when recording from a distant position. You can adjust the directivity by operating with the "-" and "+" buttons. The new zoom microphone mode adjusts the recording level higher according to the zoom.

Compact recorder with 48 kHz/16-bit linear PCM recording

Create high-quality recordings using the linear PCM format. With a sampling frequency of 48 kHz, this linear PCM format easily outclasses the 44.1 kHz / 16 bits of CD-quality audio. While this may surpass your needs in business, it is useful for those using the digital voice recorder for hobby or music, providing the quality to easily make their own CDs.

Automatic sensitivity adjustment with Intelligent Auto Mode

To make listening to your recordings more comfortable, the Intelligent Auto Mode adjusts the microphone sensitivity to match the volume of the sound source. When a speaker is talking loudly, the recorder reduces the input level, and for soft voices, the recorder increases the input level. In this way, the function automatically keeps track of the input level and simultaneously adjust the recording level so that it always records in the best quality and provides an even level of volume.

Low-cut filter eliminates extraneous noise

During recording, the low-cut filter is used to cut the sound at frequencies of 300 Hz and lower during the recording process. Typical examples of these lower frequencies include air conditioner noise, projector fan noise, and even wind noise while outside. By cutting the lower frequency during recording your audio is natural sounding and free of background noise and distortion during playback.
