摘要

A wireless microphone and/or in-ear monitoring system having a clock master prescribing a wordclock, and a clock slave to be synchronized to the wordclock. Between the clock master and the clock slave is a digital wireless transmission link which digitally transmits synchronization signals and audio signals. The clock master has a clock reference prescribing a first sample clock, and a first timer. A first phase of the first clock signal is detected after expiry of the first timer and is wirelessly transmitted to the clock slave, which has a second timer. After expiry of the second timer, a second phase of the second clock signal of the clock slave is detected and compared to the wirelessly transmitted first phase. The difference between the first and second phases is used as an input value as a control unit in the clock slave. The control unit adjusts an adjustable sample clock of the clock slave to correspond to the first clock.
