Abstract

Wireless microphones are used in a plurality of applications, such as concerts, discussions, theater performances, operas, etc. The wireless microphones are normally connected to a transmitter which transmits the audio signals captured by the microphone to a base station via a transmitting frequency. The invention relates to a microphone system (1) having a base station (3) and having a microphone module (2) wherein the base station (3) is designed to wirelessly receive audio information and/or test information transmitted from the microphone module (2) on an operating frequency, wherein the base station (3) has a receiving analysis module (14) and/or is coupled thereto, which is designed to analyze the reception quality of the audio information and/or the test information on a plurality of possible transmitting frequencies, wherein the receiving analysis module (4) is designed to select the operating frequency from the plurality of possible transmitting frequencies.
