NTi Audio Offers Rapid Frequency Response Measurements with the XL2

Do you want to measure the frequency response of a speaker or audio component, and not have to wait until the lower frequencies stabilize? NTi Audio offers an innovative and practical solution with its Minirator MR-PRO and XL2 range of measurement instruments. The measurement uses two new MR-PRO test signals and a new, matching measurement function in the XL2, in which the signals contain a 1-second and a 4-second cyclic pink noise, from which the XL2 can quickly calculate a stable measurement result in real time.
