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 center 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 center microphone is on, frequencies from 20Hz to 20kHz are picked up (60Hz to 20kHz when off), compensating for low-range sounds.
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.
