Miniature digital recorder MAG-2 is intended for high-quality recording of the acoustic information. 

MAG-2 has light and solid metal case, which protects from mechanical damage and electromagnetic control of recorders’ suppressors. 

The recorder can record phone talks, conferences, interviews etc. The information records on built-in flash memory, it makes MAG-2 “invisible” for recorder detectors. 16-bit audio codec and absence of shrinking algorithms provides high quality of recording.
