A method of controlling a wireless microphone and/or in-ear monitoring system which has a master device as a clock master and at least one slave device as a clock slave, wherein between the clock master and the at least one clock slave there is a wireless digital transmission link, by way of which both synchronization signals and also audio signals can be digitally transmitted, comprising the steps: prescribing a master audio sample clock (100, S1) which prescribes master audio sampling times (101, 102, 103) in the clock master, resetting a master phase counter each time as soon as the master audio sample clock (100, S1) prescribes a master audio sampling time, forward counting of the master phase counter (PCM, 110) with the clock of a master fine clock generator (FPGM), prescribing an adjustable slave audio sample clock (150, S2) which prescribes slave audio sampling times (151, 152, 153) in the clock slave, resetting a slave phase counter each time as soon as the slave audio sample clock (150, S2) prescribes a sampling time, forward counting of the slave phase counter (PCS, 160) with the clock of a slave fine clock generator (FPGS), generating a synchronization event which generates a fixed time relationship between the clock master and the clock slave, establishing a synchronization time on the basis of the synchronization event so that the clock master and the clock slave simultaneously reach the synchronization time, detecting a master phase from the master phase counter (PCM, 110) at the synchronization time, detecting a slave phase from the slave phase counter (PCS, 160) at the synchronization time, wirelessly transmitting the detected master phase to the at least one clock slave, comparing the wirelessly transmitted master phase to the detected slave phase, using the difference between the master phase and the slave phase as an input value for a controller of the clock slave, and adjusting the adjustable slave audio sample clock (150, S2) by the controller so that after recurrent performance of simultaneous detection of the master phase and the slave phase and subsequent processing the slave phase corresponds to the master phase so that the slave audio sampling times (151, 152, 153) correspond to the master audio audio sampling times (101, 102, 103). prescribing a master audio sample clock (100, S1) which prescribes master audio sampling times (101, 102, 103) in the clock master, resetting a master phase counter each time as soon as the master audio sample clock (100, S1) prescribes a master audio sampling time, forward counting of the master phase counter (PCM, 110) with the clock of a master fine clock generator (FPGM), prescribing an adjustable slave audio sample clock (150, S2) which prescribes slave audio sampling times (151, 152, 153) in the clock slave, resetting a slave phase counter each time as soon as the slave audio sample clock (150, S2) prescribes a sampling time, forward counting of the slave phase counter (PCS, 160) with the clock of a slave fine clock generator (FPGS), generating a synchronization event which generates a fixed time relationship between the clock master and the clock slave, establishing a synchronization time on the basis of the synchronization event so that the clock master and the clock slave simultaneously reach the synchronization time, detecting a master phase from the master phase counter (PCM, 110) at the synchronization time, detecting a slave phase from the slave phase counter (PCS, 160) at the synchronization time, wirelessly transmitting the detected master phase to the at least one clock slave, comparing the wirelessly transmitted master phase to the detected slave phase, using the difference between the master phase and the slave phase as an input value for a controller of the clock slave, and adjusting the adjustable slave audio sample clock (150, S2) by the controller so that after recurrent performance of simultaneous detection of the master phase and the slave phase and subsequent processing the slave phase corresponds to the master phase so that the slave audio sampling times (151, 152, 153) correspond to the master audio audio sampling times (101, 102, 103).
