The GRAS EQ 40PM EQset™ Miniature Production Line Microphone is a 20 kHz pressure microphone with a dynamic range of 30 dB (A) to 120 dB SPL (<3% THD), and the first microphone to include EQset technology.
According to the audio testing company, EQset technology is a new technology that guarantees fixed sensitivity and a flat response curve across all frequencies in every EQ 40PM microphone, out of the box.
With an industry-standard size of 34-mm in length, the production line microphone is aimed at increasing efficiency and improving test accuracy in the consumer audio and telecom space.
GRAS touted higher environmental stability compared to other production line microphones as another benefit of the new mic.
“The new EQ 40PM design reduces sensitivity variation to such an extent that, when used in typical production line conditions, compensation is completely unnecessary—further reducing the time needed for calculations and corrections and the associated risk of false passes and failures,” the company said in a statement.
According to the company, they have already received positive feedback about EQset and the EQ 40PM after presenting the technology to many acoustic and production experts in selected industries.
Rémi Guastavino, director of product management at GRAS, said: “By introducing EQset technology, we are proving our commitment to constantly seek new, cost-efficient and highly accurate testing solutions across the world. Innovation is at our heart and EQset is only our latest step—the market can expect more to come from GRAS in the near future.”
