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.
A microphone system (1) having a base station (3) and having a microphone module (2), wherein the base station (3) is designed to receive information, transmitted on an operating frequency, wirelessly from the microphone module (2), wherein the base station (3) has a reception analysis module (14) and/or is coupled to the reception analysis module (14) which is designed for analyzing the quality of reception of the information at a number of possible transmitting frequencies, characterized in that the microphone module (2) transmits test information on the plurality of possible transmitting frequencies, the reception analysis module (14) selects the operating frequency from the plurality of possible transmitting frequencies based on the analysis of the quality of reception of the test information, and transmits the operating frequency via a return channel to the microphone module.
A method for selecting an operating frequency for a microphone system (1) having at least one base station (3) and at least one microphone module (2), wherein the base station (3) is designed to receive information, transmitted wirelessly on an operating frequency, from the microphone module (2), wherein the microphone module (2) transmits test information on a plurality of possible transmitting frequencies, wherein a quality of reception is analyzed at the plurality of transmitting frequencies, characterized in that the operating frequency is selected automatically from the plurality of transmitting frequencies, taking into consideration the quality of reception based on the analysis of the quality of reception of the information, and the operating frequency is transmitted via a return channel to the microphone module.
