GRAS 40PM Wins Prestigious GAS Product Innovation Award
SHANGHAI, CHINA27 March 2025: GRAS is proud to announce that its groundbreaking GRAS 40PM production line microphone has been honored with the GAS（Global Audio Summit）Product Innovation Award, recognizing its exceptional advancements in five dimensions of technological innovation, design innovation, process innovation, intelligent innovation and originality.
The GRAS 40PM Production Line Microphone is the first microphone to include EQset technology—a revolutionary new advancement that guarantees fixed sensitivity and a flat response curve across all frequencies in every 40PM microphone, right out of the box.
EQset technology uses digital signal processing to ensure that all microphones of this type have a uniformly fixed sensitivity and flat frequency response across all frequencies, within the specified tight tolerances. This reduces measurement uncertainty and greatly simplifies microphone setup, monitoring, replacement, and corrections. The simplification of setup and other tasks saves both time in the setup itself and time in operator training, reducing downtime significantly to keep production running.
GRAS 40PM with EQset is a pressure microphone for measurements up to 20 kHz with a dynamic range of 30 dB (A) to 120 dB SPL (<3% THD), and its 1/4" diameter and 34-mm length make it an industry-standard-sized production line microphone. And with the EQset capabilities, this microphone is ideal for entry level test settings with focus on cost efficiency.
A particular benefit of GRAS 40PM is higher environmental stability as compared to other production line microphones. The new sensing element used in 40PM reduces sensitivity variation to such an extent that, when used in a typical production line, compensation is completely unnecessary.
In summary, GRAS 40PM is a highly stable, price-competitive, user-friendly solution that allows users to perform acoustic measurements without the normal hassles of lengthy setup time, downtime or replacement, while at the same time minimizing measurement errors better than any other production line microphone on the market. All of these factors make the 40PM the ideal microphone for production line testing of audio devices.
“We are thrilled to receive this recognition,” said Zeal Wang, AE Manager. “The GRAS 40PM embodies our mission to deliver innovative tools that empower customers to improve audio product quality and reduce production costs, help their business grow and stay at the forefront of the market. This award validates our team’s relentless pursuit of excellence.”
