A sound system with the function of displaying the on-off state and coding of the microphone channel

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.

Description

technical field [0001] The invention relates to the technical field of audio equipment, in particular to an audio system with the functions of displaying the on-off state of a microphone channel and coding. Background technique [0002] Audio system equipment is the most widely used media equipment, especially in education, business, entertainment, exhibition and other industries. [0003] The audio system mainly includes microphones, mixers, power amplifiers and speakers, etc. There is often a problem with the audio system currently in use: the person using the microphone starts to speak, but finds that the microphone cannot produce sound, which affects the quality of the performance, delays time, and appears This situation is what the tuner is most worried about, but this kind of performance accident is hard to avoid, no matter how much preparation is done in advance, this kind of situation will still happen. [0004] The common reasons for the microphone not making sound...

Problems solved by technology

[0003] The audio system mainly includes microphones, mixers, power amplifiers and speakers, etc. There is often a problem with the audio system currently in use: the person using the microphone starts to speak, but finds that the microphone cannot produce sound, which affects the quality of the performance, delays time, and appears This kind of situation is what the tuner is most worried about, but this kind of performance accident is hard to avoid, no matter how much preparation is done in advance, this kind of situation will still happen

Although the tuner can do sufficient debugging work before the start, it is difficult to avoid failures due to the large number of people in an event, time constraints, and many people are not familiar with the use of microphones.

[0005] When the tuner is testing the microphone, he usually inputs a sound signal at the microphone end, and then listens to see if there is any sound output from the speaker, but it is impossible to test like this after the program starts, and the tuner cannot detect the microphone leading to the mixer Therefore, if there is a problem with the microphone after the program starts, and it cannot be found in time, there will be a situation where the microphone does not make sound, which will affect the normal progress of the sound reinforcement, waste time, affect the effect, and sometimes cause irreparable Loss
