Abstract
The invention discloses a sound system with the functions of displaying a microphone channel conduction state and encoding. The sound system comprises a microphone and a mixer. The microphone is internally provided with a super audio signal generating circuit, a microphone code generation circuit, a microphone code serial encoding output circuit, a microphone code display circuit, a microphone circuit, and an electro-acoustic converter. The mixer is provided with a signal distribution circuit connected to a microphone input interface, a filter and amplifier circuit, a demodulation circuit, a filter circuit, an audio signal processing circuit, and a microphone code reading and displaying circuit. In the condition that system equipment is in switched on, the conduction of the whole channel from the microphone to the mixer is displayed in real time in an uninterrupted mode. If the channel has interrupption, the mixer displays no conduction and indicates a fault, otherwise the conduction is displayed. If the microphone is in no conduction, a tuner can timely carry out trouble shooting, and a condition that the no conduction of the microphone is just discovered at the beginning of using the microphone is avoided.
