GRAS EQset™ Technology
EQset is the latest innovation landmark by GRAS. This new technology, never seen in production line or measurement microphones before, enables a microphone with a preset gain, also referred to as fixed sensitivity, and a flat response. Providing engineers with high workflow efficiency as well as high measurement accuracy. Furthermore, all GRAS micophones with EQset technology are fully backwards compatible, and are rigorously tested according to GRAS standards.

Product Overview
EQset technology:
A Revolutionary Technology from GRAS
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.
Product Features
FOUR WAYS EQset Measurement Microphones Can Help Your Business
Your current production line measurement microphones waste your time and cost you money. By switching to measurement microphones with EQset technology, you’ll get:
Ease of Use
EQset-enabled microphones work out of the box and are far superior to equivalent microphones without this EQset. For example, setting up, checking, and replacing a microphone in the production setting can happen quickly and easily without any kind of individual microphone adjustment or calibration.
Cost Efficiency
EQset microphones are very price-competitive, user-friendly solutions that allow users to perform acoustic measurements without the hassles typically associated with setup time, validation, downtime, or time for replacing microphones. The added functionality combined with the reduced time needed for operator training and handling, as well as the long lifetime of the microphone, make EQset microphones by far the most cost-effective solutions available.
Reduced Risk
With EQset technology, measurement uncertainties can be reduced to a minimum. For example, in a production line setting, probably the most costly quality risk is the inherent risk of false passes. By using EQset-enabled microphones, QA departments can increase confidence in product quality by completely eliminating this risk. EQset technology ensures a factory-set fixed gain and sensitivity across all frequencies. In R&D, the complexity of compensating for sensitivities of frequencies outside the specifically calibrated frequency can be challenging and extremely time consuming. EQset removes all of that extra time and effort by providing an equalized signal with a fixed sensitivity and flat frequency response across the entire range. This simplifies the measurement process and thereby removes the possibility of correction errors.
High Stability
Manufacturing premium audio products across multiple locations can introduce testing variability due to differing environmental conditions, potentially impacting product quality. With traditional production line microphones, relative humidity, temperature, and static pressure changes can cause severe sensitivity drift. EQset microphones solve this stability issue, offering environmentally stability more like measurement microphones to ensure uniform quality assurance across different locations.
