The XL2 is a powerful Sound Level Meter, a professional Acoustic Analyzer, a precise Audio Analyzer, and a substantial Vibration Meter in one unit. Simple operation and plenty of functions distinguishes this quality Swiss product. Precise Results. Simple Operation. The Applications Room & Building Acoustics • Reverberation RT60 • Airborne Sound Insulation • Impact Sound Insulation • Noise Curves Evacuation / Installed Sound • Alarm Limits STIPA • Speech Intelligibility • Impedance Measurement (MR-PRO) Noise Measurement • Unattended Noise Monitoring • Tonal and Impulsive Noise • Rating Level...

Live Sound - Level Monitoring As long as the sound is good and the show entertaining, live sound events can be enjoyed. However, the sound level must always be below the legal limits in order to avoid possible hearing damage to the audience and to not disturb the neighbors. The standard XL2 Sound Level Meter offers this functionality. Keeping Below the Legal Limits The pre-defined profiles in the XL2 Sound Level Meter make it easy to comply with the legal limits. Switch on the device, press start - done! The XL2 measures and stores the required levels and informs the user via a tri-color...

Voice Evacuation Systems Speech Intelligibility STIPA in Evacuation Systems The XL2, with the STIPA Option, measures the speech intelligibility of the system, taking into account the background noise. Reporting tools that read the XL2 data directly, are available to produce documentation that serves as a basis for the acceptance of such announcement systems. Reverberation as a key to Good Speech Intelligibility Large venues, such as railway stations, can have a naturally long reverberation time, which can have a negative effect on speech intelligibility. Measuring reverberation time with...

Room and Building Acoustics The standard XL2 contains all the necessary functions for measuring room and building acoustics, including reverberation time in octave bands. An intelligent auto-naming process helps with the assignment of each result as a sending/receiving room or ambient level measurement. Measuring Airborne and Impact Noise The measured results can then be loaded into the optional Sound Insulation Reporter or Room Acoustics Reporter software packages. Sound Insulation Reporter creates the averaging curves and determines the standard insulation values D, Dn, DnT und R’ in a...

Noise Measurement / Remote Monitoring The XL2 Sound Level Meter provides all the functions needed to measure and monitor noise. Its removable SD card offers plenty of space to record levels, spectra and audio files. The data can also be read out during an ongoing measurement via its USB interface. With the weatherproof case and the type-approved WP30 microphone protection, self-sufficient remote measurement stations can be created. The NetBox gives communication capabilities to the XL2 via LAN or mobile data and allows access to the device via a web browser. With NoiseScout in the Cloud For...

Vibration Meter With the Vibration Option and an attached accelerometer, the XL2 is well suited for vibration analysis or as an efficient and cost-effective solution for industrial vibration quality control. The device measures acceleration for frequencies down to 0.7 Hz and calculates velocity and displacement. The results can be displayed in metric or imperial units, or as a dB value with adjustable reference level. With various filters and time weightings, a gliding RMS level for easy reading, and peak readings, the Vibration Meter is ideal for a wide range of applications. Spectral...

Manufacturing Quality Control Whether you need to measure structure-borne noise with an accelerometer or sound with a microphone, the XL2 can be easily integrated into your production line. Pass/Fail Testing The optional Spectral Limits function is particularly suitable for performing pass/fail measurements. First, a number of spectral measurements are averaged from a series of known good samples. Spectral fail limits are then calculated using a tolerance rule. Using these, the XL2 can then autonomously measure the spectrum of all products and visualize the result. Spectral Limits with...
