Acoustic Audio Analyzer System

FINE R+D))2019   10Hz - 100 kHz

Measure ANECHOIC in Normal rooms

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. It performs High Accuracy impedance measurements 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 FINE R+D Viewer shows and performs ALL that FINE R+D does, except measure. Use the Viewer as a great tool away from the measuring site: Go to FINE R+D Viewer >>
