Mar 5th, 2011 | By | Category: iPods & Portable Media Players

Olympus has introduced the DM-620 digital audio recorder, featuring  the “Tresmic” 3 microphone system that’s designed to capture a wider range of audio.

The DM-620’s Tresmic system uses two condenser stereo mics and a center, omni-directional mic that’s capable of capturing lower bass ranges down to 20Hz.

A unique feature of the DM-620 is complete voice guidance functionality: the recorder can provide audio prompts for users with assistive needs.

This optional function helps the user operate the device without the need to see the menus or buttons. Languages can be set to English, French, Spanish and Portuguese.

Other highlights of the digital audio recorder are 1,000+ hours of recording capacity.

The expected street price is $150 and availability is mid-March.
