WIRELESS AUDIO TRANSMISSION SYSTEM, PARTICULARLY A WIRELESS MICROPHONE SYSTEM
First Claim
1. A wireless audio transmission system for wireless audio transmission comprising:
- at least one wireless microphone unit for detecting audio signals and for wirelessly transmitting the detected audio signals over a first channel which is an audio channel; and
a central unit comprising;
a wireless receiving unit for receiving, over the first channel, the wirelessly transmitted audio signals from the at least one wireless microphone, unit;
a pilot tone transmitting unit for transmitting a first pilot tone signal over a second channel which is a first pilot change; and
a pilot tone receiving unit for receiving and processing a second pilot tone signal;
wherein each pilot tone signal has information with respect to the wireless transmission between the microphone units and the central unit; and
wherein the at least one wireless microphone unit is adapted to receive the first pilot tone signal and to extract information in the first pilot tone signal.
