JL Audio MAX-KIT Sound Measurement System
JL Audio MAX™ is a professional dual-FFT measurement system with five microphones. It is ideal for general audio system measurements, tuning systems with DSP, troubleshooting and device testing, and for resolving OEM integration issues. MAX™ has countless applications for home, automotive, marine and professional audio. Thanks to full integration of VXi and MVi DSP controls, MAX™ simplifies your measurement setup and allows you to perform measurements and DSP adjustments using a single computer and the TüN® 4.0 software application, which offers micro-automations that speed up equalization and channel delay setup.
Main features
- Test, troubleshoot and analyze any audio system with full detail across three dimensions of sound: level, frequency and time... all in real time!
- Simplify tuning DSP products into a car in a real environment. Simply connect the hardware, place the microphone array, run the TüN® software and tune.
- Quickly test room modes for home audio and home theater subwoofer placement and precisely adjust crossover and phase control for a seamless transition to the subwoofer.
- Evaluate individual or multiple audio zones in a marine installation in terms of frequency response and level.
- Obtain the most accurate possible measurements with 5-microphone averaging! MAX™ multiplexes up to five included microphones to perform individual FFT measurements of level and frequency response (RTA and spectrograph).
- Perform dual FFT measurements of up to five simultaneous transfer functions with accurate display of magnitude (frequency response), phase, impulse response (delay) and coherence (noise immunity).
- Each transfer function captures all audio data for real-time analysis or for comparative analysis.
- Built-in test signal generator (pink and white noise, sine waves, square waves, etc.) and the ability to play WAV files.

Powerful automations with JL Audio VXi and MVi amplifiers:
- The Automatic True Delay feature sets VXi/MVi channel delays much more accurately than any other method in a flash.
- The Autoset EQ feature sets the parametric EQ of VXi/MVi to your chosen target within seconds. You can also overlay the VXi/MVi EQ controls over the frequency response display and perform precise manual EQ adjustments with visual real-time feedback.
MAX is incredibly flexible and accurate!
- MAX™ measurement accuracy is comparable to 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 80 V, low-level analog signals up to 7 V, optical digital S/PDIF signals).
- Multiple signal outputs (built-in DAC powering analog line outputs and headphone outputs, plus optical digital output).
- Built-in USB hub simplifies connection to a computer and DSP amplifiers or other USB devices (not intended for charging devices).
What is included in the JL Audio MAX-KIT package?
- MAX-KIT includes the MAX™ hardware interface, five measurement microphones, the multi-microphone fixture, mounting accessories, cables and power supplies - all packed in a lockable waterproof hard case.
- An optional specialized probe kit for measuring speaker impedance and high voltage is available separately: the "MAX-PROBE KIT" (90922)
About JL Audio
JL Audio is an American manufacturer of consumer audio equipment specializing in home, car and marine audio. It is one of the main pioneers in car audio and is best known for its high-end subwoofers. The company was founded in 1975 and is therefore one of the oldest manufacturers in this field. Its original focus was home audio, but already in the late 1970s and early 1980s they began working in the car audio segment, whose popularity then surged. During its rich history JL Audio produced many unique and patented subwoofers that had almost no competition at the time. The same applies today. The manufacturer's subwoofers impress with their power and top-quality sound, unique patents and excellent workmanship. Especially the top W6 and W7 series have long been among the most interesting products on today's market. Also noteworthy are the revolutionary flat subwoofers of the TW1 and TW3 series and the perfectly tuned subwoofer enclosures. You can expect the same quality from their amplifiers, and they also offer top products designed for integration with factory audio systems.
