While the dual stereo microphone setup in the previous models DM‑450 / DM‑550 facilitated superb true stereo recordings, the incorporation of a third, central microphone takes quality audio capture to another level. UltimaPro microSDHC/XC with Class 10 specification perform at up to 90MB/s transfer speed and are designed to be used where fast memory cards are crucial; to capture high resolution images and to shoot Full HD video.

This amount includes seller specified domestic postage charges as well as applicable international postage, dispatch, and other fees. The DM-670 adds an extra feature over its smaller brother with Voice Guidance, allowing hands-free control of the system’s various features, along with an upgrade from 4GB to 8GB of internal storage. In addition, you can also choose WMA AND PCM; the latter meaning you can record in CD quality mode - ideal if you want to record live music. A small percentage of the storage capacity is taken for formatting and therefore is not available for storage. This helps ensure you get the product you want in a condition you're happy with, as well as reducing the miles each product travels, helping to lower carbon emissions.

Building on the company’s existing DM-450 and DM-550 models, the two new devices improve audio quality thanks to a built-in three-microphone stereo capture system which combines a pair of high-sensitivity directional microphones with a central omnidirectional microphone for total coverage. Additionally, the external microSD card slot provides location‑ and internet‑independent Data‑transfer to the computer.

The "ZOOM" Feature increases the directivity of the internal microphones to capture more focused sound in larger class rooms. This combination of mics means that recordings ‑ particularly those of the human voice ‑ are even more balanced and life‑like, covering a broader spectrum of sound, from low to high frequencies.

exe on its cards - not saying that I distrust Mr Memory but even the best cards can fail in the bell curve - if they are going to fail. It has 8GB of internal memory compared with 4GB on the DM650 4) The DM670 allows you to make up to 99 index marker points during a recording whereas the 650 only allows 16: during long recordings, the 99 come in handy! This combination of mics means that recordings – particularly those of the human voice – are even more balanced and life-like, covering a broader spectrum of sound, from low to high frequencies. The DM-670 also ups the ante with a Voice Guidance system, 99 index marks and 8GB of memory on board.
