Description

XL2 Audio & Acoustic Analyzer

 

Besides being an advanced, integrating Sound Level Meter, the XL2 measures RTA and FFT high-resolution spectra, RT60 Reverberation Time, Polarity, Delay and THD+N. Optional features are speech intelligibility STIPA, extended acoustics functions, noise curves, cinema calibration, pass/fail analysis and remote measurement acquisition. The Type Approval Option upgrades the instrument to the XL2-TA, a type approved sound level meter.

Data and audio is logged onto the SD card for transfer to the computer. The XL2 stores all reports and log files in plain text format, which can be opened with any text editing application (Notepad, Wordpad, etc). Furthermore a series of free MS Excel application templates provide a convenient way to view the measurement results of specific tasks and create simple reports. The optional XL2 Data Explorer software offers comprehensive analysis tools for logged noise monitoring data.

The wide range of functions is tailored for measurement tasks in:

  • Installed Sound
  • Life Safety Systems
  • Noise Monitoring
  • Live Sound
  • Broadcast
  • Building Acoustics
  • Industrial and Aerospace
  • PASS/FAIL Quality Control
