音响设备引由音源（音乐播放设备、拾音设备即话筒）、控制设备（模拟或数字调音台）、音频处理器（以前都是用效果器、均衡器、压限器、分频器、Signal distributors, delayers and other peripheral devices, now there are digital system controllers with all functions above the above functions), power amplifier (amplifier), and speaker composition.The above devices are used together by various types of cables and cables.
Sound equipment repair
I. The intuitive inspection method Anti -inspection method is based on the principle of simplicity, then simplicity and complexity. Through the means of seeing, hearing, nasal hearing, and hand touching, the faulty machine is generally inspected to find the parts and reasons for the failure.This method is very effective for handling some simple and obvious faults.During an intuitive inspection method, you can first check whether the external knobs, switches and signal line connections are correct, and whether there are obvious burning, discoloration, broken, and poor contact in the interior circuit.If no abnormalities are seen, you can pass the electric test machine.If there are smoke, jumping fire in the machine, or smelling the burnt flavor of the components, and hearing an abnormal noise, you should immediately cut off the power and check the causes to avoid expanding the failure.When maintaining an electronic tube amplifier, you can determine whether the filament or power supply can be determined by observing whether the electronic tube filament is shiny.In addition, after the power is disconnected, the suspicious component can be determined based on whether the component is hot.
Sound equipment installation
Step 1: Before installing the audio equipment, cut off the power supply of some other equipment, and then install the audio equipment to install the audio, speakers, HDMI, main speakers, low speakers with power supply, etc.Installation of the equipment.The installation order can be connected to the audio equipment according to your habits.Step 2: When the speaker cable is a non -finished line that needs to be opened on the line, when the opening operation is performed, it cannot be operated on other equipment, especially the audio amplifier, and stay away from the audio power amplifier and other equipment.Otherwise, the copper wire of the speaker cable is likely to enter the sound amplifier or other devices, which will damage the device.
Sound equipment debugging
Points to pay attention to tuning: 1. Generally, the tunnel of the stage hall should control the music of the stage indoors. It is best to send some auditions in each corner, so that the music effect can be better controlled.2. If necessary, you must use pressures and incentives, which can increase the loudness and beauty of music. It sounds full of music.3. For non -professional singers and professional singers, we need to make different tuning. Generally speaking, for non -professional singers, we should properly aggravate the sound, so that we can cover up the defects of noise and sound.Essence4. Generally speaking, we will use a bit of backup, which is conducive to avoiding that we cannot send signals in failure, so as to replace it with grief and anger, so that the entire audio effect of the stage is best.
Audio equipment price
First of all, Xiaobian introduces the first audio equipment.It uses imported steel magnetic coils to make the middle and treble of this audio device particularly crispy and transparent. At the same timeBalance, the effect of human voice restoration is very good, and the high frequency is relatively soft and smooth.The interior structure of the box is relatively close and has a mesh design, which can ensure the safety of the bass speaker, and can achieve a professional KTV effect when playing.The wiring uses gold -plated pure copper, which ensures zero distortion of sound quality during transmission, making the sound more full and delicate.It also has high -quality new cotton, which can avoid the turbidity of the sound well, making the sound clearer.The reference price of this audio device is around 1,000 yuan.
