The operation of the sound system is simply a kind of power transfer. In this process of transfer, the conductor wire must be used as a bridge between the devices, so the importance of the wire in the sound system is unquestionable. . A set of sound system must meet the basic requirements of sound, and any link is indispensable. The wire that is used as the signal transmission is not an accessory of the sound, but must be valued by the same level of equipment.
Everyone knows that the power source is often the heart of the device, and that the heart can output a large amount of high-quality blood, and the power cord plays a very important role as a blood vessel. Generally, the power cords that are usually supplied are mostly designed from the perspective of safety load. Of course, the amount of load power is sufficient, but it seems that the high requirements of audiophiles are still insufficient. Generally, after changing the power cord, if the original listening environment space ratio is golden ratio, because the performance of the whole sound system is greatly improved, there is a pleasure of changing a set of sound. After the replacement of the power cord, the problem of the medium and low frequency standing waves hidden in the original listening space will be exposed and become full of the world. The reason is very simple. After the power supply is improved, the amplifier draws power more smoothly, and the control and driving force of the speaker is greatly increased, and the sound energy that is pushed out may be much larger than the original, so the original medium and low frequency standing waves of the listening space are heard. It is revealed. Don't be afraid to encounter this, it means your audio is healthy, and the sound energy can be really released. At this time, we will adjust the sound and move the horn and reflect the sound absorption to control the middle and low frequency standing wave of the listening space. After the adjustment is completed, the real performance of the sound will be less than the original electric shock, and there is no illusion of the medium and low frequency standing waves, which is better and smoother. This is called death.
Many enthusiasts know how important power is to a sound combination, although some people will question the power line's effectiveness, and it is an indisputable fact that the power cord can change the sound. Generally, after changing the fever power line, there is an immediate effect on the amplification of the large current, because the power line of the amplifier requires a stable current and voltage, and the impedance inside the conductor is small and the current decay is small. The selection of the power cable is related to the power. The amplifier with a large power is often used with a large current, and a relatively thick wire needs to be selected. Fever power cord materials generally use pure copper wire with high purity, and the insulating material wrapped around the power cord has high insulation resistance and high temperature resistance. After changing the fever power cord, listening to the performance of the violin, the overtones and spatial sense of the strings are very clear, all the musical instruments are expressed, and the gloss of the piano sound is not lost due to the thickening of the intermediate frequency. The sound is full of cohesiveness, allowing you to feel the whole set of equipment more energetic, making the listener very relaxed and happy.
Fever is not a purely psychological activity. Many fevers can be explained by science. The improvement of the sound of the high-grade fever wire on the sound is definitely an absolute improvement. As for what price and value are worth, it is another problem. Many people in the forum said that their megaphone is not enough driving force like a soft-footed crab. I suggest you try the fever power cord and socket first.
CSRME safety controller is developed for standard GB27607. By monitoring machine tool safety related equipment, the security of machine control system can meet the requirements of GB27607, and its security meets the requirements of ISO13849-1 (PLe) and IEC61508 (SIL3).
With rich interfaces, CSRME has limited programmable function. It can simultaneously replace many different types of safety control modules or safety PLCs, thus greatly simplifying the safety design of machine control systems and reducing cost.
