A Low-Noise High-Output Capacitor Microphone System

Authors: Burwen, Richard S.

Journal of the Audio Engineering Society · Volume 25 · Issue 5 · pp. 278–283 · May 1977

Abstract

The dynamic range of a capacitor microphone has been considerably extended by means of an advanced FET feedback amplifier. This microphone delivers +20 dBm into 600 ohms at maximum sound pressure levels of 110, 125, or 140 dB. Its A-weighted noise level of 15 dB is contributed mostly by the capsule instead of the amplifier.
