GRAS Releases New Production Line Measurement Microphone with EQset Technology

GRAS Sound & Vibration, announced the new GRAS EQ 40PM-1 microphone. This new miniature microphone joins the already successful family of GRAS measurement microphones with EQset technology, lowering the cost of precision in production line acoustic measurements. GRAS EQset technology essentially guarantees fixed sensitivity and a flat response curve across all frequencies, out of the box, vastly reducing the risk of measurement errors. The GRAS EQ 40PM-1 with EQset is an upgraded version of the EQ 40PM, the first in the EQset line.

audioXpress interviewed Rémi Guastavino, Director of Product Management at GRAS Sound & Vibration, to uncover the details of the new EQset measurement microphone series.
