Numerous measurement variations are simultaneously available. Actual level (live), Lmin, Lmax, Leq and Lpeak may be measured in combination with frequency weighting A, C or Z and time weightings fast, slow and impulse. All results are simultaneously available and may be stored automatically for later documentation.
Customers may log all acquired level information onto a removable SD card. Additionally the XL2 offers wav-file recording for a complete documentation of the measured sound pressure levels. Voice notes may also be added to each measurement.

Real Time Analyzer RTA
The RTA perfectly suits tasks such as optimization of sound systems and rooms. The XL2 measures and logs wideband values and the real time spectrum in 1/1 or 1/3 octave-band resolution according to IEC 61260 class 0. The sound level meter results of the wideband and RTA spectrum are simultaneously available.
