Home Audio () PS Audio gave this product a very interesting name, called Power Plant, which is a power plant. Of course, P10 Power Plant cannot be a real power plant because it No electricity will be generated to give you the sound of your home, but you can "regenerate" the power, convert, purify, and reform the mains plugged in from the wall, and then output the "new" power supply, so that your baby's sound is not necessary. And then with Datong electric pot, mother music washing machine and eat, and enjoy a fever power that may be more pure than the dedicated power cord.
To be so amazing, what method does the P10 Power Plant (hereafter referred to as P10) use to regenerate the power supply? Before explaining its principle, we must first understand how the general power supply filter works. Most power supply filters or power processors are Passive, that is, the use of passive components such as resistors, capacitors, transformers, coils, etc. to form a filter circuit to purify the power supply. However, PS Audio believes that this method cannot add the lost energy back to the power supply, so it cannot completely solve the communication. The fundamental problem of the mains. Why did you lose energy? Where did the power go? It was separated by other electrical appliances in your home. And it was not tightened. Other appliances were running, and noise was generated and sent back to the power supply. It is also given to your baby sound, the sound performance will be affected. This is why listening to the sound in the middle of the night is better, because most of the home appliances, lights are off, even your neighbor's electricity is reduced, The power supply is cleaner and more abundant, and the sound is naturally nice.
PS Audio believes that the use of passive components to form a filter circuit to purify the power supply cannot add the lost energy back to the power supply. Therefore, the fundamental problem of AC mains cannot be completely solved. Therefore, the P10 Power Plant power processor has been developed. Its basic architecture and The post-stage expansion machine is almost the same, using the amplification method to regenerate the power supply.
In this case, P10 must use the "active" way to handle the power supply, and can also regenerate the power supply? Yes, the P10 is basically like a post-stage amplifier, with a super-heavy-grade toroidal transformer, rectification and filter circuit. And the power crystal locked on the heat sinks on both sides, through the process of alternating current → direct current → alternating current, through the power crystal to reproduce the perfect waveform of 60Hz sine wave, which is the ideal power supply, solve the voltage instability and noise interference in one fell swoop. , distortion, harmonics and lack of dynamics.
For any power filter or processor, especially a model with many components like the P10, will it restrict the power supply and affect the dynamic performance, which is the topic that potential buyers are most concerned about. P10 There are three solutions, one is to prepare 1,500 watts of power in one breath, so that the audio equipment is inexhaustible; the second is to have 2 groups of 4 high-current sockets, specializing in comprehensive expansion or post-stage use; Low output impedance (less than 0.015 ohms) ensures smoother power output and unlimited dynamics.
The P10 backplane provides 5 sets of 10 power sockets. You can see that the E and D areas on the left are high current settings. They are designed for use in integrated amplifiers or rear stages. You can also see the jacks when they are not in use. The inside of the baffle will seal itself and have dustproof function.
Power purification is not seen in the P10, but the P10 has many "see" features that can be monitored and operated by the full-color Touch Screen on the panel, allowing users to fully manage their power supply. In this way, there is a set of RJ45 network route jacks behind the P10. After connecting to the network, users can monitor or operate from the remote through the network. Even if people are not at home, they can immediately grasp the power status or operate. Shut down. For example, before going home from work, you can turn on the power in the company through the Internet, let the equipment warm up, and you can listen to it when you get home, you don't have to wait.
The P10 has so many functions, so I will use the photos of the P10 panel one by one.
After P10 is turned on, it will enter this screen, indicating that there are 5 groups of 10 sockets in front of A, B, C, D, and E. The green indicates that the group of sockets is currently open. Press the socket on the screen to close it. This set of sockets, so each group can be individually controlled. The four circles below can enter various function options.
The socket that can't be used can be turned off. This is a big advantage of the P10. I touched the C and E sockets on the panel and turned them off directly, so it was displayed in red.
Please pay attention to the second blue circle on the lower right side. The output waveform (WAVEFORM) is switched from the SINE of the previous figure to the MULTI.P10 of this picture. It provides two kinds of output waveforms, namely sinewave and multiwave. The difference is that multiwave is like The filter capacitance of the equipment has become larger, which increases the power storage capacity and reduces the chopping, so it sounds more natural.
