Minirator MR-PRO is a compact, indispensable and portable analog audio generator that includes an impedance meter and cable tester. NTi Audio part # . The 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 favorites to this set. Besides the broad range of generated audio signals, the Minirator MR-PRO monitors the signal balance, phantom power and impedance of the connected load. An integrated XLR cable tester simplifies trouble shooting tasks. Applications include speech intelligibility STIPA, installed sound, AV installations, cinema, live sound setup, broadcast and studio, and building acoustics.
