Digital Video Recorder comes with a small removable stereo microphone.
Requires 2 batteries.
256MB internal memory. No SD slot card unlike the Zoom H2.
I've had 10 months.
I tried the Zoom H2 but the DS30 has the advantage of being half the size and half the price.
The recording quality is WMA max 128Kbit which is not fantastic. The zoom is better on this point.
The DS30 has three gain settings. The registration of a repeat rock saturated with a battery even slightly with the lowest gain.
Another concern is handling noise that stand out a lot when the microphone is plugged directly into the recorder. Me with this problem less shocked with the Zoom H2.
I could resolve the concerns of noise manipulation and increase sound quality by changing the original microphone to a stereo electret microphone conference mounted on a small foot.
Finally the machine does not seem to be a rock-solid.
A 97 € on amazon is a good product. However, if it again I would choose probably the Zoom H2.
