When you decide to use top-quality speakers for the improvement of sound effects, how to equip them with high-quality top-quality amplifiers so that the speakers can be used, and the sound quality, tone and effects can be improved to a higher level.
At present, good professional speakers are nothing more than original imported speakers and speakers assembled with high-quality imported speakers or domestic high-quality speakers. This type of speaker has good sound quality and strong sound performance, so the quality level of the power amplifier is also proposed. Higher requirements.
In the practical process of sound reinforcement for many years, you may have noticed such a situation: when you use imported speakers with domestic general amplifiers, the overall sound quality is also good. However, if the imported power amplifier is used, the sound quality of the speaker will be much better than the domestic power amplifier. The clear, round, plump, clean, and soft style characteristics are immediately revealed.
When using ordinary speakers, you may feel that there is no big difference in sound quality and tone color with any power amplifier. But when you choose top-quality speakers, you will find that using a good power amplifier and using a normal power amplifier may have a world of difference in sound quality.
In fact, this is the concrete manifestation of the practical advantages produced by complementary advantages and strong alliances.
The speaker quality of imported professional speakers is good, the crossover circuit is reasonable, the phase is strictly corrected, and the phase of the high, middle and bass of the speaker is reasonably connected. There is no lack of sound in any frequency band, and there will not be too much energy overlap, so the sound quality The bottom is clean and the sense of hearing is distinct. Although the impact of speakers on sound quality and tone color in a sound system is decisive, the impact of power amplifiers on sound quality is also crucial.
A good speaker is accompanied by a good-quality power amplifier to promote its clean, layered sound quality characteristics. Therefore, it is pleasant to hear, easy to resonate, and never tire of listening.
We all have a certain knowledge and understanding of lakes, seas and rivers. In a sound system, speakers and power amplifiers are like lakes, seas and rivers. Rivers are power amplifiers, and lakes or seas are speakers.
A top-grade sound box is like a large lake or sea with a sandy bottom, and a top-grade amplifier is like a river on a sandy bed. The sandy river bed has a strong ability to absorb and filter impurities, so the water quality of the river is clean and clear. This kind of originally clean and clear river water flows into a large sandy bottom lake or sea with a stronger ability to absorb impurities and filter pollution. Impurities are deposited and fixedly absorbed, and the lake or sea water becomes cleaner and clearer.
Anyone who has been to the beaches of Yalong Bay in Hainan will be impressed by the crystal clear waters there. The reason why the sea there is so clear is that its seabed is pure sand and rock, and the sand is white and clean like white jade. This sandy seabed has a very strong ability to absorb and filter impurities, so the sea is turbulent again. Surging, the water quality is also clean and clear.
On the contrary, if the river is a muddy river bed, the muddy river will be produced when the river flows and washes the bottom of the river and the soil loosens on the bank. The muddy river is injected into the muddy bottom lake or the sea, then the lake or the sea will be even worse. turbid.
Therefore, when choosing general speakers, there is no need to use high-quality power amplifiers, but when you use high-quality top-quality speakers, you must choose top-quality power amplifiers, otherwise the sound quality and effects of good speakers may not be able to be used normally .
The background noise of a good power amplifier is low, and the control is strong. When coupled with a top-quality speaker, the sound is clean, clear, plump and round, and flexible, with a distinct sense of hearing and pleasant listening.
In practice, in addition to the above characteristics, it can be stable and durable. It is undoubtedly a top-grade power amplifier. It can achieve this level of power amplifier. It not only has reasonable and excellent circuit design, but also has high-power and low-consumption high-quality components. , And the component design and matching are full of materials is usually the biggest feature of this type of power amplifier.
Some people say "If the power amplifier is good or not, just push 4Ω speakers." Although this is not absolute, it makes sense. In order to reduce the manufacturing cost of many power amplifiers, the design of transformers, radiators, power tubes, and capacitors are very "saving". When facing low-impedance speakers that require fast power conversion, the heat of the power amplifier rises sharply. One of the most direct factors of instability, ranging from frequent interruptions to "protection", can cause the power amplifier to be "worn and ill-fated".
Some people use low-quality power amplifiers to push 4Ω speakers. Because the power output is severely distorted when the power is placed in a 4Ω impedance load state, the control and sound quality become worse, so they think that the sound quality of low-impedance speakers is not as good as high-impedance speakers. This is the industry The biggest misunderstanding that has always existed in China.
Therefore, when you decide to use a good speaker, remember not to choose a poor power amplifier in order to reduce a little cost, otherwise, the desire and original intention of improving the sound quality may be difficult to achieve.
In the face of the current situation of the industry that sells power amplifiers at "cabbage prices", how to identify the performance and quality of power amplifiers requires not only a real comparison, but also your comprehensive knowledge and experience. Sometimes, just having a pair of good ears may not be enough. You must also practice a pair of "golden eyes and fire eyes"...
