NEW from GRAS - World's first Intelligent Microphone Set!

SysCheck2™ - at the hear of  the world's first truly intelligent microphone set!

SysCheck2™ is a new GRAS-patented technology by which the two new microphones GRAS Type 246AE (free-field) and Type 246AO (pressure field) are equipped with a high-precision built-in microprocessor able to generate a reference signal that enables remote verification of the entire measurement chain.  It is a tool that allows test and production engineers to remotely check the health of microphones, channel gain and cable integrity.

SysCheck2™ enables users to quickly validate calibration and system function with a single click and requires no physical interaction with the microphone.

It is easy to set up with standard cables making it adaptable for any testing setup and is highly recommended for applications such as production line, distributed measurement setups, and anywhere where regular and rapid human-free function measurement verification + environment sensing (temperature, pressure and humidity) is required.

The verifications are easily made on each SysCheck2™-enabled microphone connected to a CCP/IEPE/ICP/CCLD power module with transducer electronic data sheet (TEDS) support and measurement software. SysCheck2™ functionality also provides on-demand environmental data: temperature, barometric pressure and humidity.

NEW - 1 and 4-channel CCP power supply with TEDS

TEDS support, single or quad channel power supply for CCP microphone sets

The GRAS 12BA is a single-channel, and the Type 12BB is a four-channel, USB-powered module  (power supply) with TEDS support for CCP (constant current power) microphone sets.

These power modules provide power to one or four CCP (otherwise known as IEPE) microphone sets without signal degradation, gain modification, or attenuation.

They are intended as simple and cost-effective interfaces between TEDS-enabled measurement microphones and analysers which will automatically extract TEDS data for seamless integration.   It can also be used with other analysers that do not offer automated interrogation, using a utility program to access the TEDS data using a PC. This program can be downloaded from the GRAS website.

Power for the 12BA and Type 12BB is provided through a USB cable using a USB 2.0 or USB 3.0 port and a USB-C port on the power module.

Multiple power modules can be used concurrently.

FLAT - FAST - PRECISE                       The World's Thinnest Condenser Microphones!


Validation of CFD (Computer Fluid Dynamics) modelling is an important part of designing vehicles.  However, airflow and turbulence cannot be fully simulated and predicted realistically. For these reasons, high-quality measurements are a must.


GRAS has developed the new UTP microphones – Ultra Thin Precision microphones.

They combine all the advantages of the classical measurement microphone – wide frequency range, accuracy, and repeatability – with an ultra-small form factor, only 1 mm in height.

In essence, the UTP microphones are FLAT, FAST and PRECISE - ideal for measurements in boundary layers and turbulence.
