JL Audio MAX-KIT Audio Measurement System for VXi and MVi Amplifiers - Open Box

MAX Audio Measurement System

MAX™ is a professional-grade, dual FFT measurement system with five microphones. It is 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 and professional audio. 

With full integration of VXi and MVi DSP controls, MAX™ simplifies your measurement setup, allowing you to perform measurements and DSP adjustments with one computer and one software application: TüN™ 4.0, which offers micro-automations that speed up equalization and channel delay setting.

What can you do with MAX™?

• Test, troubleshoot and analyze any audio system with full detail on the three dimensions of audio: level, frequency and time… all in real time!
• Streamline the tuning of car audio DSP products in real-world shop environments. Simply connect the hardware, place the microphone array, launch TüN™ software and go!
• Quickly test room modes for home audio and home theater subwoofer placements, and accurately adjust crossover and phase controls for a seamless transition to the subwoofer.
• Evaluate individual or multiple audio zones in a marine installation for frequency response and level.
• Get the best measurements possible with 5-microphone averaging! MAX™ multiplexes up to five included microphones to conduct single FFT measurements of level and frequency response (RTA and spectrograph). 
• Conduct Dual FFT measurements of up to five simultaneous transfer functions with precise displays of magnitude (frequency response), phase, impulse response (delay) and coherence (noise immunity). 
• Each transfer function captures all the audio data for real-time or comparative analysis. 
• Built-in Test Signal Generator (pink and white noise, sine waves, square waves, etc.), plus WAV file playback capability.

Powerful Automations with VXi and MVi amplifiers:

• Automatic True Delay feature sets VXi/MVi channel delays in a flash, far more accurately than any other method.
• Autoset EQ feature sets the VXi/MVi parametric EQ’s to your selected target, in seconds. You can also overlay VXi/MVi equalizer controls over the frequency response display to perform precise, manual EQ adjustments with real time visual feedback.

MAX is Incredibly Flexible and Accurate!

• MAX™ measurement accuracy is on par with professional test equipment that sells for tens of thousands of dollars.
• Wide Range of Inputs (up to five microphones, high-level analog signals up to 80V, low-level analog signals up to 7V, optical digital S/PDIF signals)
• Multiple Signal Outputs (built-in DAC feeding analog line level outputs and headphone outputs, plus optical digital output)
• A built-in USB Hub simplifies connection to computer and DSP amplifiers, or other USB devices (not intended for charging devices).

What is in the Kit?

• The MAX-KIT includes the MAX™ hardware interface, five measurement microphones, a multi-mic fixture, mounting accessories, cables and power supplies, 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), or Mac (OS X Catalina or newer)
• JL Audio's free TüN 4 software, available here
• A mic stand or tripod to support the multi-mic holder.
