XL2 Acoustic Analyzer

A unique combination of state of the art sound level meter, comprehensive acoustical analyzer and a powerful audio analyzer.

Acoustic analyzer measures sound level, 1/3rd octave real time spectrum, FFT, RT60 reverberation time, delay, polarity, STI-PA speech intelligibility (optional)
Audio analyzer function measures Level RMS, THD and frequency
Flexible user interface with personalised application profiles
Sound level meter meets the international standards for environmental Noise (DIN15905-5 DE / SLV 2007 CH) including the required correction values
Voice Notes for logged measurements
Generates 48 VDC phantom power and offers automated microphone identification
Mini-SD-Card, removable
Built-in real time clock
Rechargeable replaceable Li-Po battery
M4260 microphone must be ordered separately
