　　What are the common problems of KTV audio equipment

　　(1) Common problems of the mixer itself:

　　1. The volume fader is not well touched, and the sound is intermittent during operation.

　　2. The channel input port is faulty, and it is easy to "uproot".

　　3. The control system is disordered. In short, the fault of the mixer is nothing more than the input part, output part, control part, power supply part, etc., which are generally caused by the aging of the equipment.

　　(2) Common problems of equalizer:

　　1. The touch failure of the push-pull keys of the equalizer is the most common, mainly due to the aging of the equipment and the harsh environment.

　　2. The internal circuit fault of the equalizer, for example, there is only one signal output.

　　(3) Compressor, electronic frequency divider, professional reaction suppressor, professional delayer and other common problems:

　　In addition to the serious aging of these devices, there are generally no major problems. At most, the adjustment knobs and the signal sockets on the rear panel are a little problematic.

　　(4) Common problems of digital effectors:

　　1. Noise problem. The digital effector has certain digital noise when processing audio signal. If the signal cable is not well shielded, the noise will be the same as rain in severe cases.

　　2. The central part of the digital effector is the digital processing chip. When these digital chips have problems, they can be turned on but cannot be operated. There is no way to adjust and use the programs inside, and there is no way to repair such a complicated digital chip. .

　　(5) Common problems of professional power amplifiers and speakers:

　　1. The most common problem of professional power amplifiers is bad capacitors or burning of the power amplifier tubes. This is a common use problem, but most of it is still unstable in the equipment itself.

　　2. Some power amplifiers will have a problem that there is no sound in one channel, and the problem is still the circuit inside.

　　3. As for other problems, the power amplifier volume potentiometer is not well touched, the left and right channels are unbalanced, the maintenance function is too frequent, the rear panel operation switch is not well touched, and the signal jacks are problems. In short, the power amplifier is now in the KTV sound system. A kind of electrical equipment that is more prone to malfunction.

　　4. Of course, the most common problem with the speaker is the speaker. It can be said that the most common problem in a professional audio system is the burning of the speaker. Of course, this is a human factor, but most of it is still the quality of the speaker itself.

　　5. Another common problem of KTV speakers is the aging of the wiring ports and poor touch, especially the frequently active KTV speakers are prone to this problem.
