GRAS 67AX ø400 mm CCP Ground Array Microphone Kit
Freq range: 3.15 Hz to 20 kHz
Dyn range: 22 dB(A) to 150 dB
Sensitivity: 12.5 mV/Pa
Typical applications and use
- Ground array measurements
- General noise measurements
- Ideal for the aerospace industry
The 67AX is a ground array microphone kit designed for the aerospace industry, i.e. for measurement of noise from overhead aircraft.
The microphone set is designed to sit asymmetrically in the mounting to attain a more uniform frequency response for measurements.
The GRAS 47AX microphone is a IEC 61094 1/2'' CCP Flush-mount Microphone Set with a dynamic range from 22 dB to 150 dB and a frequency range from 3.15 Hz to 20 kHz. Its height of only 8 mm (to the diaphragm) is the ideal match for the design of the 67AX. The built-in preamplifier is a low noise constant current power (CCP) type, with a built-in TEDS circuit for automatic transducer identification.
