Leading Features for absolute accessibility
Made for unconditional support, the DM‑770 provides fully‑fledged professional features for blind touch use. The enhanced Voice
Guidance in seven languages (EN, FR, DE, ES, IT, RU and SV) in combination with Distinctive Button Contours provides the
operation by touch alone.
As the predecessor DM‑670 before, the DM‑770 includes the TRESMIC System for superb stereo recordings. The two stereo
microphones are supported by one omni‑directional microphone ‑ this combination of mics means that recordings ‑ particularly
those of the human voice ‑ are even more balanced and life‑like to capture. To ensure, that every lecture is recorded in minute
detail.
In case of noisy surroundings, the "Scene Select" and the "ZOOM" feature help to improve the recording situation. The "ZOOM"
Feature increases the directivity of the internal microphones to capture more focused sound in larger class rooms. With six different
scenes, the recorder provides a default setting for different use scenes.
Beside this, with a weight of 72gr the DM‑770 is almost feathery and weighs 40‑50% less than the global best‑selling smartphones
(as of 2015). Additionally, the external microSD card slot provides location‑ and internet‑independent Data‑transfer to the computer.
In combination with the Advanced‑Version of our Olympus Sonority Software “Audio Notebook Plug‑In” students can use the digital
voice recorder (DVR) as a daily helper in university and school.
