Speaking of power, I believe that everyone has the same mood: but hehe. Obviously, the power supply can be said to be the basis of everything. If the power supply is insufficient, the machine will not be full, and the horses that can't eat enough can run well; if the power supply is dirty, the noise stream will be streamed. If there are too many impurities in the blood vessels, how can people get healthy? So everyone knows that power is the most important thing. The problem is, how to make your own power.
Here, I want to talk to readers about my own experience and opinions. However, you don't expect too much, because I am just like you, facing the power supply, there are very few available chips. However, I am more fortunate than you are that I have had many years of experience in decorating, and each time I will have a different situation. Up, my experience may be more abundant than you. The following are the principles of geometry that I think most people can do.
Analogy and digital division
First of all, the first priority of the power supply is "people and cars lanes". Sorry, it is "analog and digital". The meaning of such ratios and digits is very broad, not only for sound. How do you say this? Let's take a look at the indoor lighting equipment. In the average family, there are probably four kinds of fluorescent lamps, halogen lamps, power-saving bulbs (fake white heat bulbs, in fact, fluorescent lamps) and white heat bulbs. These four kinds, in addition to the white heat bulb is to rely on the burning of chicken to shine, the other must rely on the transformer, in an alternative way. That is to say, in addition to the white heat bulb, other lamps will affect the purity of the power supply due to the 60Hz flashing or the noise generated by the transformer heating. In addition, the dimmer itself will also emit noise. Light fixtures that are not clean enough not only affect the power supply, they also make noise, which affects the quietness of the music. If you don't believe it, please turn on the fluorescent light in the dead of night to hear if there is very low frequency noise. From the above description, you will find that the illuminating condition of the incandescent bulb is continuous, that is, analogous; and the light emitted by the fluorescent lamp is a discontinuous fast flashing, it is digital. So I said that in lighting, the analogy and the number are also separated. I mean: If you are listening to music, it is best to only turn on the white light bulb. Wait until you want to see the atmosphere before you turn on the other lights.
In addition, I have said many times that all electrical appliances with motors should not be stringed together with the audio power supply. Because as soon as these electrical appliances are activated, noise will continue to enter your audio power supply. Maybe you haven't tried this, but I will give another example to illustrate: My VTL350 used to make a very small noise in the speaker because of a switch contact problem. When I plug the laptop into the power supply. When the same socket is turned on and the computer is turned on, the noise in the speaker is immediately enhanced. Turn off the computer power, and the noise will be restored. You see, even a high-end laptop, with its power and sound connected, will have this effect, not to mention the refrigerator and the dryer.
Let's talk about the analogy of audio equipment. Because digital lines are very afraid of interference, they also interfere with others. That is to say, the digital device is very isolated, so the lonely person makes it lonely, lest it not be gregarious. The audio digital equipment is like this, it is best to give them an independent power supply, do not mix with other audio, so as not to be mistaken.
Adult and child table
The so-called adult is the latter stage of high power; the so-called child is the predecessor. If adults and children eat at the same table, adults always eat more and faster, and children can only be left behind. Although the power consumption of the previous stage is small, how can it be enough? However, when some pure Class A high-power rear-ends are always consuming power, the power supply at home will also affect the predecessor. Therefore, the front stage draws a separate line for it, and the latter stage gives it a separate one, so that they won't grab each other, and everyone will be safe.
The farther the power box is, the thicker the power cord is.
The power box of the average person's home and your audio room should not be together again. Sometimes, the power box is in the living room, the sound room is in the farthest room, and the two corners of the sea are all according to one side. At this time, the audio fans are the most headaches. time. If you want to pull the power from the power box, the road is far away, and you have to wear a hole in the wall. If you are wronged to use the wall socket, you know that it is not enough. What should I do? Of course, there are only two ways. When the smart person looks at it, he uses the wall socket to pull the card and insert it. Anyway, my sound is not so good. People like this will not be bothered. However, some people are pursuing the spirit of Hi End, so be sure to get the power to your satisfaction. At this point, the only way is of course to ask the electrician to pull the cable.
The wire has to be pulled very long, and the current is consumed by a long current, so in general, the wire diameter is thicker. How thick is it? My experience is: If the electrician tells you that "generally thicker is enough", you add three times the thickness, which is enough. How to go the power cord? In order to avoid the impact, my experience is that the wall is relatively inconspicuous, and it is better to protect the power cord with a soft iron pipe for electricians, so as not to break the wires themselves; The mouse acts as a molar tool. Because of the limited diameter of this kind of soft iron pipe, if you use it, you can't pull a thick power cord. In fact, I don't think it is necessary to be thick enough. Usually, you tell the electrician how thick it is, the electrician will tell you that the power company has not given you such a large amount of electricity, and the use of such a thick line is also white. This is really justified, but most of the audio fans can't listen. My opinion is that the electrician does not understand the role that the audio fans need in addition to the practical value, but also the psychological comfort compensation.
The power cord should not be stringed together. After the power cord is pulled out of the power box, it will be divided into many sockets. This will be enough at the end of the pipeline. The best way is to pull out a few lines from the power box, each line is a socket. In this way, the power of each socket is sufficient. Of course, if you want to do this, you must have a prerequisite, that is, your audio room is with the power box, so there is a way to pull it. Otherwise, pull out so many groups at a time, how do I see these lines go?
What I said above is what most people can do. Others like the real ground wire pulling the ground rod, there are not a few people can do it. Or if you apply to a power company for a battery, it is a privileged class. As for the power processor that most people like to use, it is beyond the scope of this article. My opinion is that very few power processors are fully effective and have no side effects. Therefore, instead of eating up the day after tomorrow, it is better to practice the body innately and replace the power processor with a sufficient and clean power source.
Someone would say that even if I make the power of my home, but the neighbor's electrical noise will not be in my house? In the apartment, I think this is inevitable. In this case, isn't it what I said above? Isn't that saying that if you do, things may not be so bad. If you don't do it, things will get worse. What's more, it doesn't cost much to do so, maybe it will fall if you buy a signal line less. Like me, because I have two independent power boxes, I use one for the audio, and the other for all the electrical appliances and lighting in the house. I don't think there will be many people who have two power boxes at home! But don't envy me. I live in an apartment. I still have problems with you.
