Compact, battery-powered 4 channel data recorder for sound and/or vibration.
The Rion DA-20 is a 4 channel battery-powered data recorder. The DA-20 can be used with a wide range of sound or vibration sensors and records the signals as multi-channel wav files onto a compact flash card (so, unlike PC-based recorders, it is totally silent).
With simple “Play” and “Record” buttons operation of the DA-20 is extremely easy and intuitive.
