XL2-Sound-Level-Meter

XL2 Professional Sound Level Meter

The XL2 Analyzer forms the unique combination of a state-of-the-art Sound Level Meter, a comprehensive Acoustic Analyzer as well as a powerful Audio Analyzer. A range of measurement microphones with an electronic data sheet are available to suit your requirements.

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, 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 your PC. Free reporting tools are available for download. The wide range of functionalities is tailored for measurement tasks in:

• Installed Sound
