摘要：
There is provided a wireless audio transmission system, in particular a wireless microphone system, for wireless audio transmission. The system has at least one wireless microphone unit for detecting audio signals and for wirelessly transmitting the detected audio signals, and a central unit. The central unit has a wireless receiving unit for receiving the wirelessly transmitted audio signals from the wireless microphone units, a pilot tone transmitting unit for transmitting a first pilot tone on a pilot channel, and a pilot tone receiving unit for receiving and processing a second pilot tone signal. The pilot tone signal has information in respect of the wireless transmission between the microphone units and the central unit.
