Claim:
1. A method for assigning frequencies to a wireless radio audio transmission system having (1) a plurality of wireless transmitters which each have at least one non-linear transmitting amplifier, and (2) at least one wireless receiver, comprising: wirelessly transmitting audio signals from at least one wireless transmitter of the plurality of wireless transmitters to the at least one wireless receiver; establishing a first wireless transmitter of the plurality of wireless transmitters which, in a switched-on condition, is configured to approach a third wireless transmitter below an established minimum spacing that would create an intermodulation effect; establishing a second wireless transmitter which, in a switched-on condition, is not to approach another wireless transmitter below the minimum spacing; assigning a first transmission frequency to the first wireless transmitter and a third transmission frequency to the third wireless transmitter, having regard to possible intermodulation effect; and assigning a second transmission frequency, corresponding to an intermodulation frequency of the first and third frequencies, to the second wireless transmitter.
