Description

MAX Audio Measurement System

MAX™is a professional-grade, dual FFT measurement system with five microphones. Itis ideal for general audio system measurements, system tuning with DSP,troubleshooting and testing equipment, and solving OEM integration challenges.MAX™ has many applications in home audio, car audio, marine audio andprofessional audio. 

Withfull integration of VXi and MVi DSP controls, MAX™ simplifies your measurementsetup, allowing you to perform measurements and DSP adjustments with onecomputer and one software application: TüN™ 4.0, which offers micro-automationsthat speed up equalization and channel delay setting.

What can you do withMAX™?

·        Test, troubleshoot andanalyze any audio system with full detail on the three dimensions of audio:level, frequency and time… all in real time! 

·        Streamline the tuningof car audio DSP products in real-world shop environments. Simply connect thehardware, place the microphone array, launch TüN™ software and go! 

·        Quickly test roommodes for home audio and home theater subwoofer placements, and accuratelyadjust crossover and phase controls for a seamless transition to thesubwoofer. 

·        Evaluate individual ormultiple audio zones in a marine installation for frequency response andlevel. 

·        Get the bestmeasurements possible with 5-microphone averaging! MAX™ multiplexes up to fiveincluded microphones to conduct single FFT measurements of level and frequencyresponse (RTA and spectrograph).  

·        Conduct Dual FFTmeasurements of up to five simultaneous transfer functions with precisedisplays of magnitude (frequency response), phase, impulse response (delay) andcoherence (noise immunity).  

·        Each transfer functioncaptures all the audio data for real-time or comparative analysis.  

·        Built-in Test SignalGenerator (pink and white noise, sine waves, square waves, etc.), plus WAV fileplayback capability. 

Powerful Automations with VXi and MVi amplifiers:

·        Automatic True Delayfeature sets VXi/MVi channel delays in a flash, far more accurately than anyother method. 

·        Autoset EQ featuresets the VXi/MVi parametric EQ’s to your selected target, in seconds. You canalso overlay VXi/MVi equalizer controls over the frequency response display toperform precise, manual EQ adjustments with real time visual feedback. 

MAX is Incredibly Flexible and Accurate!

·        MAX™ measurementaccuracy is on par with professional test equipment that sells for tens ofthousands of dollars. 

·        Wide Range of Inputs(up to five microphones, high-level analog signals up to 80V, low-level analogsignals up to 7V, optical digital S/PDIF signals) 

·        Multiple SignalOutputs (built-in DAC feeding analog line level outputs and headphone outputs,plus optical digital output) 

·        A built-in USB Hubsimplifies connection to computer and DSP amplifiers, or other USB devices (notintended for charging devices). 

What is in the Kit?

·        The MAX-KIT includesthe MAX™ hardware interface,  five measurementmicrophones, a multi-mic fixture, mounting accessories, cables and powersupplies, all packed in a locking, waterproof hard case. 

·        An optional,specialized probe kit for speaker impedance and high-voltage electrical measurements is available separately: “MAX-PROBE KIT” (90922) 

What else will you need: 

·        A PC (Windows 10), orMac (OS X Catalina or newer) 

·        Our free TüN 4software, available below

·        A mic stand or tripodto support the multi-mic holder.
