XL2 + M2211 Microphone
Sound level meter / analyzer NTI Audio XL2 + Class 1 (IEC 61672) microphone 21-144dB
The XL2 Analyzer is the unique combination of a state-of-the-art sound meter, an extensive Acoustic Analyzer, as well as a powerful Audio Analyzer. Three different microphones are available with an electronic record (TEDS).
In addition, this integrating / advanced sound meter offers the possibility of FFT analysis and 1/1 octave to 1/16 octave band measurements, RT60 reverberation time, Polarity, Delay and THD + N. Optional functions are speech intelligibility STIPA, extensive acoustics functions, cinema calibration, pass / fail analysis and remote measurement. Data and audio is stored on the SD card for transfer to your PC. Free reporting tools are available for download at NTI. The wide range of functionalities is tailor-made for measurement tasks in:
• Sound installation
• General noise measurements
• Sound monitoring
• Events
• Broadcast
• Building acoustics
• Industrial and road traffic noise
• PASS / FAIL Quality control
