A sound system with coded microphone channel on-off state visible

Abstract

The invention discloses a microphone channel on-off state visual sound system with a code. The system comprises a microphone and a mixer. The mixer is equipped with a microphone input interface. An ultra-audio frequency signal generation circuit, a microphone code generation circuit, a microphone code serial output circuit, a microphone code display circuit, a modulation circuit, a mixing circuit, a mixing signal processing circuit and an acoustic-electric conversion circuit are arranged in the microphone. The mixer is equipped with a signal distribution circuit connected with the microphone input interface, a filtering amplifier circuit, a demodulation circuit, a microphone code reading display circuit and an audio signal processing circuit. Under the condition that a system device is started, the on-off of a whole channel from the microphone to the mixer can be displayed continuously in real time. The mixer displays switch-off if interruption exists in the channel, otherwise the mixer displays switch-on and it indicates that the channel from the microphone to the mixer is in a normal working state. If the microphone is not switched on, a tuner can timely eliminate a fault, and the condition that switch-off is discovered when the sound system comes into use can be avoided.

Description

technical field [0001] The invention relates to the technical field of audio equipment, in particular to an audio system with coded microphone channel on-off status visible. 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 are: the person using the microp...

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
