    600 000 310 - Overview

    NTI MR-PRO Analog Audio Generator provides a complete set of analog audio test signals for the most demanding audio professional. In addition to all MR2 features, MR-PRO adds load impedance and phantom voltage measurements, user wave files, higher performance and cable test capability. Hand-held, using battery or external DC power supply, the generator offers a complete range of capabilities for a professional.

    Set-up and Maintain Audio Systems:
    Use the Minirator to set up PA systems and monitors. Generate pink noise and optimize the frequency response of your system with the XL2 Analyzer. Confirm that all speakers have the same polarity with the polarity signal. To optimize delay speakers, generate the delay test signal, and measure the actual acoustic delay with the XL2 Analyzer.

    The Minirator signal generator and XL2 Analyzer are valuable instruments for fast troubleshooting of the audio signal path throughout the installation. The MR-PRO verifies phantom power supply of microphones, checks XLRLR cables and measures load impedance and balance.

    Verify Speech Intelligibility of Life Safety Systems:
    The Minirator MR-PRO generates the STIPA test signal for system line inputs in conjunction with speech intelligibility measurements performed by the XL2 analyzer according to IEC 60268-16.

    Impedance Testing of 70V/100V Distributed Systems:
    The MR-PRO measures the impedance and power rating of distributed speaker systems. Deviations from the expected result identify problems such as bad connections, incorrect tap connections or short circuits. Use the optional 70V/100V Protection Adapter for safe operation.

    Insulation Measurement for Building Acoustics:
    The Minirator MR-PRO generates band-limited pink noise for sound insulation, absorption, privacy and articulation index measurements. The following test signals support your applications:
    32 Hz - 16 kHz in individual octave bands
    20 Hz - 20 kHz in individual third-octave bands
