NTi Audio provides contractors and audio engineers with a comprehensive set of diagnostic and measurements tools. They are tailored for installing, commissioning and troubleshooting sound and audio systems in large commercial spaces so that the PA system produces acceptable levels of intelligibility of speech, the background music is audible and at a pleasant level and, most critically, announcement and emergency messages are loud and clear wherever you may be located in the building.
“What’s that hum? Why is there no sound?”
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 XLR cables and measures the load impedance of 70/100 Volt speakers.
Polarity, Delay, Reverberation Time
Use the MR-PRO with the XL2 for an in-depth verification of the polarity - frequency relation for speaker cabinets or other multi-way systems. Configure your delay speakers and analyze the reverberation time RT60 to improve the sound quality and speech intelligibility.
Noise Curves and System Spectral Response
Generate pink noise with the MR-PRO and optimize the frequency response of your system with the XL2 Analyzer. Measure the spectral distribution of the ambient noise with the optional Noise Curve function to verify if the noise rating requirements are met.
Speech Intelligibility
The XL2 measures the intelligibility of speech in an installed environment and generates a measurement report. The measurement set provides you with detailed analysis of sound pressure level, frequency response, reverberation time, ambient noise and distortion, all of which influence speech intelligibility.
Impedance Testing of 70/100V Systems
The Minirator 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.
