How does the power amplifier tube in the power amplifier affect the sound quality

Time:2023-03-06 Views:1203
    There are many power amplifiers on the market, including karaoke power amplifier, AV power amplifier, HIFi power amplifier, professional power amplifier, etc. Many people have some misunderstanding about the use of power amplifier tubes. They think that the more power amplifier tubes, the more power and sound. Now, let‘s talk about the problem of the power amplifier tube that makes people love and hate.
    In the Hifi field, some people would not hesitate to use more than one million to buy a set of high-end Hifi equipment to listen to music. This high-end Hifi equipment restores high-fidelity and lossless music. This equipment requires extremely high production technology. The circuit and voltage can be optimized to use as low as one pair of power amplifier tubes to have sufficient output power. Because at the same power, the more power amplifier tubes, the greater the heat, the worse the stability and the worse the sound. It can be popularly likened to a person who sings clearly. The more people sing together, the more muddy the voice will be. The same is true for AV power amplifiers. Because the speaker power used for home audio and video is not high, most of them use more than two pairs of power amplifiers.
    In the field of karaoke, there are two types of karaoke power amplifier and professional pure post-stage power amplifier. Karaoke power amplifier is also known as combined power amplifier. The power is generally within 350W, and more than three pairs of power amplifier tubes are generally used. Because the power of professional pure post-stage power amplifier is more than 2000 W, the power amplifier tube will be used more.
    At the same power (full power), the less power amplifier tubes are used, the higher the technical content required, and the higher the requirements for power amplifier components. Let‘s talk about the pure post-amplifier.
    Currently, there are two types of pure post-stage power amplifier on the market, one is the power amplifier using switching power supply, and the other is the power amplifier using transformer. Whether the power amplifier works stably or not and whether the power amplifier tube plays well depends on the power supply stability, voltage size and circuit optimization. Generally, users who pursue shock power+good sound quality will prefer to choose the power amplifier of the transformer, mainly because the switching power supply is not stable during power supply, and there will be less sound and distortion when working for a long time.
    The power amplifier using the transformer must choose the pure copper transformer, because only the pure copper transformer has great advantages in stability, energy storage, durability and other aspects, and only the pure copper transformer can use fewer power amplifier tubes to restore a better sound. Many manufacturers use low-grade raw materials because of poor technology, poor line optimization, and need to use more power amplifier tubes to achieve the desired power. They are fooling consumers under the banner of using too many power amplifier tubes and my power amplifier is very enough. Many of our kind consumers are also imbued with this wrong perception, resulting in not enjoying the high-quality music they deserve.
    So we should polish our eyes and choose the power amplifier that is really suitable for us.
