In one embodiment, the invention is a microphone system for adjusting the final output sensitivity of a microphone. The system includes transducers that output transducer signals. The system also includes bias circuits providing bias signals to the transducers, as well as amplifiers to receive the transducer signals and output amplified signals. The amplified signals are summed by a summer, which outputs a summed signal. A controller receives the summed signal, and is configured to obtain a desired microphone output characteristic and calculate adjustment amounts based on the characteristic. The controller modifies signals from the transducers based on the adjustment amounts. The controller then outputs a microphone signal based on the summed signal. In another embodiment, the invention provides a method for adjusting the final output sensitivity of a microphone.
