NTi Audio XL3 Acoustic Analyzer

The XL3 is a professional sound level meter and acoustic analyzer dedicated to noise measurements, room acoustics and building acoustics applications. The intuitive user interface is optimized for basic noise monitoring applications as well as offering extensive analysis tools for professionals. The sound level meter is fully networked and therefore allows operation and data access from any mobile device.

SMART USER INTERFACE

The large 4.3" IPS color touch display offers an excellent resolution of 480 x 800 pixels. This allows the intuitive control of all measurement functions in multiple languages and presents noise level readings in large, clear digits. Select between a traditional white, blue or black background theme - just as you might do on your smartphone. An additional haptic keypad with eight buttons controls the common instrument functions, such as power on/off for the XL3 and start/stop for the measurement.

BE CONNECTED

The XL3 includes an integrated web server and file server accessible through the instrument's built-in Wi-Fi or LAN connectivity. Just use your preferred web browser and connect to the sound level meter through the NTi Connect service. The instrument can be controlled by an authorized user from anywhere in the world. Alternatively, you can connect directly to the device's IP Address through your local network – e.g., in building acoustics, the impact sound level measurement can be started directly from the sending room.

All measurement data can be easily downloaded without interruption to an ongoing measurement. To log prevailing weather conditions, a weather station can be added. Additionally, the online XL3 synchronizes to the actual time automatically using the ntp protocol. This and the optional APIs for controlling the instrument to retrieve historical and current noise, audio and weather data simplifies the integration into monitoring systems.

OPEN DATA FORMAT

All measurement data is stored in an open txt-format on a removable 32 GB SD card for download via USB-C. This capacity can be increased to terabytes of storage with a larger SD card or an external SSD. Additionally, an audio signal is recorded. The XL3 is optimized for integration into customized noise monitoring applications - the sound level readings may be optionally streamed in an efficient binary format. At the same time the live audio is available online for identifying annoying noise sources.

SWISS PRECISION ENGINEERING

This sound level meter builds on the latest processor and display technologies to provide a comfortable user experience. High-performance hardware packed in a robust housing offers precise 96 kHz data sampling in 32-bit resolution. With a frequency range from 0.3 Hz – 45 kHz, the XL3 is prepared for infra and ultra sound measurements. With single-range measurement and the automated sensor detection reading the electronic data sheet from the connected measurement microphone, the XL3 Acoustic Analyzer is indeed the equivalent of a Swiss Army knife for noise measurement professionals.
