PURPOSE: A wireless microphone system is provided to have ten channel modes to allow a micro module and a repeater to respectively select available channels, so as to output high-quality voice signals without false cross though used with another microphone system at the same time in a same space. CONSTITUTION: A micro module(100) of which operation power is provided by a charger has a plurality of frequency channels to which a plurality of voice signals are inputted. Also the micro module(100) compresses audio signals with one frequency channel of the plurality of frequency channels and transmits the compressed audio signals. A charging part charges the charger. A repeater(102) has the charging part built-in, and restores the compressed audio signals from the micro module(100) with at least one of the plurality of frequency channels to generate the restored audio signals. And an external audio apparatus(104) outputs the audio signals from the repeater(102).
