Microphone link system

A microphone link system is disclosed that comprises a microphone converting an acoustic sound signal into an electrical sound signal, a slave unit to which the microphone is connected, a master unit, and a bus connecting the slave unit to the master unit. The slave unit comprises an analog-to-digital converter that is configured to convert the electrical sound signal into a digital sound signal; a signal processor that is connected downstream of the analog-to-digital converter and that is configured to process the digital sound signal into a data signal; and a bus interface connected between the signal processor and the bus. The bus interface provides to the slave unit electrical power taken from the bus, sends the data signal to the master unit via the bus and receives from and sends to the master unit control signals via the bus.
