MAX™ Audio Measurement System

MAX™ is a professional-grade, 5-microphone, dual FFT measurement system designed for general audio system measurements, system tuning with DSP, troubleshooting and testing equipment, and solving OEM integration challenges. With accuracy on par with professional test equipment costing tens of thousands of dollars, MAX™ lets you to tune, test, troubleshoot and analyze virtually ANY audio system in detail, from car audio, marine audio, home and professional audio, even live audio.

For VXi and MVi amplifier users, MAX™ includes full integration of amplifier DSP controls to vastly simplify your measurement setup, allowing you to perform analysis and DSP adjustments with one computer and one software application: TüN® 4, which offers micro-automations that speed up equalization and channel delay setting.
