02. April 2015 Easy testing of Class-D Amplifiers Class-D (or switching) amplifiers are popular, not only because of their light weight, but mainly because they are highly efficient, with less power distributed as heat. Their audio parameters, however, can be difficult to measure because of high-frequency noise produced at the output stage. NTi Audio solves this by filtering out these unwanted noise components with the FX100 Audio Analyzer plug-in module filter, providing reliable test measurement of class-D amplifiers. Read more
08. April 2015 Low Frequency Noise – the XL2 now offers a valuable Toolbox for effective Assessment The Data Explorer PC software for the XL2 Sound Level Meter now includes a series of professional tools for detailed analysis of low-frequency noise (LFN). The graphical representation of time varying frequency components offers an efficient process for identifying the presence and level of LFN. Also the associated high quality audio recording supports further correlation with the objective measurement data. Read more
20. April 2015 Octave and one-third octave band measurements with the FX100 Audio Analyzer Octave and one-third octave band representations of measurements are widely used for real-time acoustic spectral analysis (RTA) in sound level meters. Audio Analyzers, on the other hand, typically represent spectrums with high-resolution FFT's. There are also audio measurement applications where standards require octave or one-third octave band measurements. NTi Audio provides a tool to derive octave and one-third octave band results from FFT measurement results using the FX100 Audio analyzer. Read more

04. May 2015 Advanced RT60 Reverb Measurement with the XL2 The XL2 is a precise and reliable RT60 measurement instrument. In addition to the T20 calculation, the XL2 Sound Level Meter now measures reverberation time using the T30 method. This enhancement is in line with the current ISO3382 standard and is free for all XL2 customers. Read more
02. June 2015 Loudspeaker Testing - Simple & Reliable like never before Testing your loudspeakers, transducers or subassemblies has never been easier. Just connect your device under test (DUT) directly to your FX100 Audio Analyzer and begin measuring. No more hassle with external amplifiers, cable dangle or measuring errors due to uncalibrated gain. The new integrated FX-SIP module with its powerful amplifier offers unrivalled performance, reliability and ease-of-use. Read more
10. June 2015 XL2 Sound Level Meter – just turn it on! The XL2 Sound Level Meter is renowned for providing precise measurements through a simple user interface. Now it just got better. The newly-available "Locked Run" mode of operation means that the XL2 only has to be switched on for measurements to happen automatically. To further ensure continuation of sound level logging, all keys on the device are locked. Read more
