Introduction
The GRAS 46AM is a 1/2" Constant Current Power (CCP) free-field microphone set designed for medium sound pressure level measurements across a wide frequency range. It is ideal for general acoustic diagnostics and is TEDS compatible, ensuring data safety and reducing measurement errors through a simple and robust design.

Specifications
- Frequency Range: 3.15 Hz to 31.5 kHz
- Dynamic Range: 25 dB(A) to 149 dB
- Sensitivity: 14.5 mV/Pa
- Temperature Range: -30°C to 70°C (-22°F to 158°F)
- Humidity Range: 0 to 100% RH
- Compliance: IEC 61094-4 WS2F, CE/RoHS compliant

Design and Components
The microphone set includes a high-quality IEC 61094 WS3F standardized GRAS 40AM 1/2” Prepolarized Free-Field Microphone and a GRAS 26CA 1/2” CCP Standard Preamplifier. The components are assembled in a clean-room environment to ensure reliability and performance.

Applications
The 46AM is optimized for acoustic applications where the sound source location is known, making it suitable for general acoustic measurements. For higher temperature applications, GRAS probe microphones are recommended.

Compatibility and Calibration
The microphone set requires a constant current input module with 4 mA and 24 V CCP voltage supply. It is IEEE 1451.4 TEDS v. 1.0 compliant, allowing for easy data management. Calibration is recommended annually, with options for GRAS Traceable and Accredited Calibration.

GRAS 46AM 1/2'' CCP Free-field Standard Microphone Set, Wide Frequency Electronic Data Sheets you will be able to read and write data like properties and calibration data. System verification The functionality of TEDS is very useful to determine which microphone is connected to which input channel. However, it is not a check of whether the microphone is within specifications or not. For daily verification and check of your measurement setup, we therefore recommend using a sound source like the GRAS 42AG Sound Calibrator. For proper sensitivity calibration we recommend using a reference sound...
