JL Audio MAX™ Kit
JL Audio bring the next level of system measurement with the JLMAX-KIT, a dealer focused 5 microphone arrangement allowing for increased accuracy and automation.
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.
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).
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.
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), our free TüN 4 software (link at the bottom of this page), and a mic stand or tripod to support the multi-mic holder.
