SysCheck2™ – The First Intelligent Acoustic Sensor System

8 August 2022

SysCheck2TM Technology

SysCheck2TM is a new GRAS-patented technology by which the two new microphones GRAS 246AE and 246AO 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.

SysCheck2TM enables users to quickly validate their calibration with a single click and requires no physical interaction. It is easy to set up with standard cables making it adaptable for any testing setups and is highly recommendable for both production line and distributed measurement setups.

Built-in Self-verification

  • End-to-end verification of the measurement signal chain without requiring an external calibrator or any physical intervention by the user.
  • Monitoring of environmental data, including temperature, barometric pressure and humidity at the point of use.
  • Easy visual assessment of microphone health and/or location via RGB LEDs on the microphone preamplifier body.
