In the field of professional sound reinforcement, the configuration of audio equipment is very sophisticated, and the configuration of power amplifier and speakers is important. Although some speaker production instructions recommend the specific brand or model of the power amplifier to the user, There are still limitations, because users often face many types of power amplifiers and have no way of starting.
There are many aspects involved in the configuration of power amplifiers and speakers, such as the brand of audio power amplifier, the choice of power tube type, and which audio power amplifier should be configured for low-sensitivity speakers. The specific configuration of power amplifiers and speakers is generally related to the designer's experience, hobbies, listening habits and other factors, and it is difficult to find a unified standard. Sometimes we encounter some users or designers who often configure speakers with low-power audio amplifiers in order to save money, and some users configure speakers with high-power audio amplifiers for the so-called "sufficient power reserve". This configuration will cause damage to the device. In the power amplifier and speaker configuration, the power of the audio power amplifier is indeed the key, that is to say, the principle of determining the power of the audio power amplifier should be unified.
Everyone knows that after the acoustic design of the hall, the speaker power needs to be determined according to a series of calculations, and then the power of the amplifier is determined by the speaker power, but how to match the power of the two to achieve the best match?
Generally, the power loss of the treble of the speaker is much lower than that of the woofer, in order to balance the high and low sounds; and the power amplifier is like a current modulator. Under the control of its input audio signal, it outputs different currents to the speakers to make it happen. Sound, under certain impedance conditions, it is actually very easy to make a power amplifier with a nominal power of 200W reach 400W or several times the output, but the distortion of the power amplifier will greatly increase, this kind of distortion is mainly produced in the middle and low frequency signals The greater the distortion of the high-frequency harmonics, the greater the energy of the high-frequency harmonics.
These high-frequency distortion signals will all enter the tweeter along with the high-frequency music signal, which is why the tweeter will burn when a small power amplifier pushes a large speaker. In the concept of many people, as long as the power amplifier power is large, it is possible to burn the speakers. Although some power amplifiers do not have a distortion indicator, due to the inherent inadequacy of the entertainment audio equipment configuration, distortion may occur from time to time in use, and the distortion indicator has no meaning at this time. Moreover, due to the limitations of the user's experience and quality, the distortion of the power amplifier is often easily overlooked.
