A microphone transmitter has a microcontroller that operates in a high gain mode when the portable housing is in a horizontal position or in a low gain mode when the portable housing is in a vertical position. In another implementation, the microcontroller operates in one of the following modes: (1) operate the microphone at a low microphone gain when the portable housing is in a vertical position and when voice activity is detected; (2) operate the microphone at a lower microphone gain when the portable housing is in a vertical position and when no voice activity is detected; (3) operate the microphone at a high microphone gain when the portable housing is in a horizontal position and when no voice activity is detected; or (4) operate the microphone at a higher microphone gain when the portable housing is in a horizontal position and when voice activity is detected.
