Two directional microphones positioned at a 90 degree layout, allows for high quality recording with an authentic stereo experience. The recording is highly precise, with this format, allowing the listener to feel as if they are actually in the recording scene.


Voice Filter clarifies and enhances the sound of the words being spoken by cutting out ambient sounds in high and low frequency ranges. This makes it easier to understand the speaker during playback.


The new Intelligent Auto Mode function makes it easier for recorders by automatically adjusting the microphone sensitivity, unlike previous models that required adjustment for the volume of the environment. To set this function, select Auto for the recording level from the menu.


Selecting from the menu, you can choose the best record setting for the environment. The Pocket mode is best for recording a wide range of voices from your pocket. The Dictation Conference or Meeting modes allow for high-quality recordings in large, loud environments where a quick response is required.


A built-in USB port lets you connect directly to a PC for simple data transfer. Just remove the cover to exchange data with a PC or recharge the unit without removing the battery.
