Key Features

Compatibility

Works with IEPE and conventional preamplifiers
The AWA14523 infrasound wideband Microphone is compatible with IEPE or conventional preamplifiers from various manufacturers. IEPE is a general-purpose constant-current-source power-supply technology used in preamplifiers. Different manufacturers may use different names, such as ICP (Integrated Circuit Constant Current Source) and CCP (Constant Current Source).
Calibration

Factory calibrated with traceable certification
Each measuring microphone is calibrated at the factory using traceable calibration equipment and comes with a calibration certificate. Recalibration is recommended at least annually.
Quality and warranty

Built for stability and durability
The microphones utilize a second-generation alloy diaphragm, a high-strength protective grille, and synthetic corundum insulators, making them stable and reliable measuring microphones on the market. Compared to traditional nickel and stainless steel, the alloy diaphragm offers superior corrosion resistance, high-temperature stability, shock resistance, and specific strength. All microphones are assembled and tested in a Class 1000 cleanroom to ensure product consistency and stability. The microphones come with a one-year warranty, and we will provide users with comprehensive after-sales support services.
