Test Solution for PA Rental

Basic Speaker Testing

The XL2 with Spectral Limits Option offers an efficient, low-cost solution for the quality control of speakers at PA Hire. Measurements can be compared against a reference curve with customized tolerance bands.

The pass/fail results are provided by the internal tri-color LED or an optional external Stack Light. Integration tools for automation and remote operation are provided.

Measurement Functions

XL2 with M4260 Measurement Microphone

FFT Analysis

Compares the high-resolution acoustic pattern of any device against a pre-defined reference sample with a pass/fail analysis in linear X-scaling.

1/12 Octave Analysis

Passed/Failed measurements with selectable 1/1, 1/3, 1/6 or 1/12 octave band resolution in logarithmic X-scaling.

Pass/Fail Measurements

The XL2 Analyzer captures the frequency spectrum of reference speakers/microphones and supports generation of tolerance bands based on the captured reference data. Measurements can either be displayed as absolute traces or shown relative to previously stored traces. Frequencies with failed results are individually visualized in every frequency band.


XL2 12th Octave Spectra

Stack Light

Provides visual pass/fail indication.

NTi Audio Stack Light

Auto-start Function

Measurement starts by automatic level trigger, external foot switch or instrument start button.

Tolerance Management

Tolerance curves can either be imported from txt-files or directly derived from captured measurements. The XL2 calculates tolerance bands based on

  • Single captured results
  • txt-files manually generated on the PC
  • Mean average of multiple captures
  • Min/Max curves of multiple captures

Digital I/O Adapter PCB

For automated operation with external peripheral devices the XL2 Analyzer can be linked into a programmable logic controller. The Digital I/O Adapter is tailored for rail mounting in electric switch boxes.
