Key Features

Compatibility

Works with IEPE and conventional preamplifiers
The AWA14426 measurement 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 Power Supply) and CCP (Constant Current Power Supply).

Calibration

Factory calibrated with traceable certification
Each measurement 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 second-generation alloy diaphragms, high-strength protective grilles, and synthetic corundum insulators, making them stable and reliable measurement microphones on the market. Compared to traditional nickel and stainless steel, alloy diaphragms offer 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. Microphones come with a one-year warranty, and we provide comprehensive after-sales support.
