The Minirator MR-PRO provides a full set of analog audio signals including sine wave, pink noise, white noise, delay test signal, polarity test signal, stepped sweep and continuous sine sweep. Further, a set of wav-files, useful for system optimization, is stored in the internal flash memory. Add your own personal favourites to this set Installed Sound Life Safety Systems Live Sound Broadcast Building Acoustics Industrial and Aerospace Quality Control The Ever-ready Pouch protects the instrument during transport and operation. With its convenient belt clip, the instrument can be kept close by for those tasks requiring both hands. The Ever-ready Pouch allows operation of the instrument while fitted in the pouch. MR2 requires additional Shock Protection Jacket
