½" Free-field microphone Type 40AM - Prepolarised, Wide-frequency

The Type 40AM is a high precision microphone for laboratory work and as a working standard microphone in calibration laboratories. It covers a frequency range from 3.15 Hz to 40 kHz. Its small size and lower sensitivity make it extremely robust and stable.

The Type 40AM is capable of measuring sound levels up to 160 dB re. 20µPa.

This microphone is similar to the Type 40AC but, as a prepolarised condenser microphone, it does not require an external polarisation voltage and can be used with G.R.A.S. CCP* preamplifiers such as the Type 26CA.
