GRAS Launches EQ 40PM EQset Miniature Production Line Measurement Microphone

February 15 2023, 01:10
GRAS Sound & Vibration, part of Axiometrix Solutions, announced a new miniature production line microphone, which is the first with the recently announced GRAS EQset technology designed to reduce the risk of measurement errors. The new EQ 40PM EQset, a short 20kHz pressure microphone with a dynamic range from 30dB (A) to 120dB, and the same dimensions as traditional Production Line microphones, is aimed at increasing efficiency and improving test accuracy in the consumer audio and telecom space.
 

The new GRAS EQ 40PM EQset Miniature Production Line Microphone is the first microphone to include the new EQset technology — an important new advancement for the audio industry that guarantees fixed sensitivity and a flat response curve across all frequencies in every EQ 40PM microphone, out of the box.

The GRAS EQ 40PM is an industry-standard size (a 34mm long 1/4" microphone) production line microphone. But with the EQset capabilities and unmatched environmental stability, this microphone will benefit any production line and is especially appealing for entry level test settings with a focus on cost efficiency.

Each EQ 40PM ensures a uniformly fixed sensitivity and flat curve thanks to the EQset technology. This “equalization” of every EQ 40PM reduces measurement uncertainty and greatly simplifies microphone setup, monitoring, and replacement, and eliminates correction when setting up new production lines and replacing microphones on existing lines. The simplification of setup and other tasks also saves time, not only for the setup itself, but also for operator training. More importantly, the EQ 40PM with EQset eliminates the inherent risk of false passes and false failures on production lines.
 

An additional cost benefit of the uniformly fixed sensitivity and flat response curve of each EQ 40PM is that, because there is no need to make individual corrections for each microphone, there is no need to store that correction information via TEDS. This enables EQ 40PM production line microphones to be used effectively with systems based on audio sound cards using 48V phantom power as well as any CCP-based system already in use, so there is no need for price-prohibitive new equipment or retooling of existing CCP-based systems.

Yet another benefit of GRAS EQ 40PM with EQset is higher environmental stability as compared to other production line microphones. 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.

"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," explains Rémi Guastavino, Director of Product Management at GRAS Sound & Vibration.

The new GRAS EQset technology is already generating an enthusiastic response during the presentations that GRAS is promoting to many acoustic and production experts in selected industries, where the new EQ 40PM measurement microphone is also demonstrated.
