The new FINE R+D can sample at 48, 96 and 192 kHz, and measures SPL and impedance up to ~100 kHz in NORMAL Rooms. Expensive Anechoic rooms are no longer needed. (Smart-) Speakers, Amplifiers, microphones and crossovers can be directly measured. High Accuracy impedance measurements are performed in 2 modes: LO (Low current), HI (High current).

FINE R+D saves ALL time data so the engineer can change the FTT window and other settings later, giving unseen flexibility. Also Polar plots, Contour plots and automatic conversion from measured frequency responses are included. The new Normalisation Mode is ideal for Microphone measurements and relative SPL responses.

The new Multimicrophone Array module for FINE R+D 2020 greatly helps making multiple microphone measurements.

You can measure SPL from 3 microphones simultaneously with one click. Choose 30 kHz or 100 kHz GRAS microphones:
