EQset concept

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.

FOUR WAYS EQset Microphones Can Help Your Business

Your current production line microphones waste your time and cost you money. By switching to microphones with EQset technology, you’ll get:

Reduced Risk

With EQset technology, measurement uncertainties can be reduced to a minimum. One of the costliest quality risks is the risk of false passes. With EQset technology, QA departments can increase confidence in product quality by completely eliminating this risk. EQset technology ensures that your products are tested with the precision and consistency necessary to maintain your brand’s reputation.

Ease of Use

Once your signal chain is calibrated for an EQset microphone, there is no need for further adjustment even if you change the microphone for another one of the same type. This is because all these microphones are virtually the same thanks to EQset. The plug-and-play design of EQset microphones will help you maintain a steady production flow, meet your deadlines, and keep your customers satisfied.

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.

Cost Efficiency

Microphones with EQset technology are highly price-competitive and user-friendly, allowing the user to perform acoustic measurements without the hassles typically associated with setup time, validation, downtime, or time spent on replacing microphones. The attractive price, time saved on operator training and handling, and the long life of the microphone, makes it the by far most cost-efficient Production Line microphone available.

A good unit (e.g.: loudspeaker) may fail testing and be discarded due to inaccuracies in the frequency response of traditional PL microphones (False Failure). Also, a defective unit might incorrectly pass testing and be classified as functional (False Pass)

Manufacturing focus: Lowering the cost of precision on the production line

Optimize Quality Assurance Across Different Locations

Production of premium audio products across multiple locations can introduce variability due to differing environmental conditions.

The unique design of EQset microphones gives them unmatched environmental stability: The sensitivity deviation on a typical production line* is less than ±0.3 dB despite changes in temperature, static pressure, and relative humidity. This means there is no need for corrections due to environmental changes over the course of a normal day in a typical production-line environment. This consistency simplifies compliance with your testing requirements and ensures that quality remains uncompromised across all production sites.

*Typical environmental conditions on a production line are defined by temperature varying between 13 and 35°C (55 to 95°F), static pressure varying between 983 and 1043 hPa, and non-condensing humidity.
