JL Audio JLMAXKIT: MAX-Series Audio Measurement System

The JLMAXKIT is a professional grade, dual FFT Measurement System that includes 5 microphones.  It is ideal for general Audio System Measurements, tuning through DSP, troubleshooting and testing equipment, and solving OEM integration challenges.  JLMAXKIT has many applications in home, car, marine, and professional Audio.

Through full integration of VX / MVI-Series DSP controls, JLMAXKIT simplifies your Measurement setup, allowing you to perform measurements and DSP adjustments through 1 computer and software application: tun 4, which offers micro automations that speed up equalization and channel delay setting.


What can you do using the JLMAXKIT?

• Test, troubleshoot and analyze any Audio System through full detail on the 3 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 tug software and go!
• Quickly test room modes for home Audio and 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 through 5 microphones averaging!  The JLMAXKIT multiplexes up to 5 included microphones to conduct single FFT Measurements of level and frequency response (RTA and spectrograph).

• Conduct dual FFT Measurements of up to 5 simultaneous transfer functions through precise displays of magnitude (frequency and impulse response (delay)), phase, 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 and square waves, etc.), plus WAV file playback capability.

Powerful automations through VX / MVI-Series amplifiers:

• Automatic true delay feature sets VX / MVI-Series channel delays in a flash, far more accurately than any other method.
• Autoset EQ feature sets the VX / MVI-Series parametric EQ's to your selected target, in seconds.  You can also overlay VX / MVI-Series equalizer controls over the frequency response display to perform precise, manual EQ adjustments through real time visual feedback.

JLMAXKIT is incredibly flexible and accurate!:

• JLMAXKIT Measurement accuracy is on par through professional test equipment that sells for tens of thousands of dollars.

• Wide range of inputs (up to 5 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 feeding analog line level and headphone, plus optical digital outputs)

• 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 JLMAXKIT includes the MAX-Series hardware interface, 
5 Measurement microphones and a multi 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: "JLMAX-PROBEKIT

What else will you need:

• A PC (windows 10), or mac (OS X Catalina or newer)

• Free tun 4 software
• A microphone stand or tripod to support the multi microphone holder.
