Abstract (en)
[origin: WO2017174589A1] A wireless microphone and/or in-ear monitor system is proposed that has at least one clock master (TM) for prescribing a word clock and at least one clock slave (TS) that can be synchronised to the word clock prescribed by the clock master (TM). Between the clock master (TM) and the at least one clock slave (TS) there is a digital wireless transmission link that digitally transmits both synchronisation signals and audio signals. The clock master (TM) has a clock reference in order to prescribe a first sample clock (S1). The clock master further has a synchronisation interface (SY) for wirelessly transmitting a synchronisation word (S). The clock master (TM) has a first timer (T1). A first phase (P1) of the first clock signal (S1) is detected after expiry of the first timer (T1) and the first phase (P1) is wirelessly transmitted to the at least one clock slave (TS). The at least one first clock slave (TS) has a second timer (T2). After expiry of the second timer (T2), a second phase (P2) of the second clock signal (S2) of the clock slave (TS) is detected and is compared with the wirelessly transmitted first phase (P1). The difference between the first and second phases (P1, P2) is used as an input variable for a control unit (R) in the at least one clock slave (TS). The control unit (R) adjusts an adjustable sample clock of the at least one clock slave (TS) such that it corresponds to the first clock (S1) of the clock master (TM).
