(1) Common faults of the mixer: 1. The volume fader is not in good contact, and the sound is intermittent during work. 2. The channel input port is faulty. For example, the XLR input port of the old Budweiser mixer is easy to "uproot". 3. The control system is disordered. Once I used a Soundcraft 16-channel mixer, it turned out that there was no signal coming out of the total output. Later, it was changed to the group output. After the next group, there was no signal output, and it was pushing the *0 channel. When it goes out, it is indeed the sound of the *1 channel. Later, I tried to output the signal through AUX, etc., but * this mixer still completely failed.

(2) Common faults of the equalizer: 1. The contact fault of the push-pull key of the equalizer is the most common, mainly due to the aging of the equipment and the harsh environment. 2. The internal circuit of the equalizer is faulty. Some equalizers have only one signal output. Later, it was found that the circuit was broken, and there are many such equalizers.
(3) Common self-failures such as compressors, electronic frequency dividers, professional feedback suppressors, and professional delay devices: These devices generally do not have major problems except for the serious aging of the equipment. The panel signal jack is a little buggy.

(4) Common faults of digital effector: 1. Noise problem. The digital effector has certain digital noise when processing audio signals. If the signal line is not well shielded, the noise will be like rain in severe cases. 2. The core part of the digital effect device is the digital processing chip, and these digital chips also have failures.

(5) Common faults of power amplifiers and speakers: 1. The most common faults of power amplifiers are bad capacitors or burnt power amplifier tubes. This is a problem we use, but most of them are still unstable. 2. Some power amplifiers will have a failure of a channel without sound, and the problem is still the internal circuit problem. 3. As for other faults, there are problems such as poor contact of the power amplifier volume potentiometer, unbalanced left and right channels, too frequent protection functions, poor contact of the switch on the rear panel, and signal jacks. An electrical device that is prone to failure. 4. The most common fault in the speaker part is of course the speaker problem. It can be said that the most likely fault in a sound system is to burn the speaker. Of course, this is caused by human factors, but most of it is the quality of the speaker itself. 5. Another common fault of the speaker is the aging of the wiring port and the poor contact, especially the frequent flow of the speaker is prone to this fault.
