Some frequently asked questions about power amplifiers

The output power of the power amplifier should be selected according to the use occasion, the sensitivity and matching degree of the speaker, and many other considerations. Generally speaking, the power of power amplifiers for home use should be between 10-100W, while the power of power amplifiers for large-scale performance venues needs to reach several kilowatts or even higher.

Distortion refers to the phenomenon that the output signal is inconsistent with the input signal after the signal is amplified by the power amplifier. There are many types of distortion, such as harmonic distortion, intermodulation distortion, etc. Among them, harmonic distortion is the most common one.

There are many ways to reduce the distortion of power amplifiers, such as using high-quality electronic components, rationally designing circuits, increasing negative feedback, and so on. In addition, using high-quality audio cables and speakers can also effectively reduce distortion.

When choosing a power amplifier, several factors should be considered, such as output power, output impedance, audio quality, input interface and output interface, etc. In addition, it is also necessary to consider the purpose and environment of the power amplifier in order to choose the most suitable model.

The maintenance and maintenance of the power amplifier need to pay attention to dustproof, moistureproof, shockproof, and do not overload it for a long time. In addition, it is also necessary to regularly clean the surface and interior of the power amplifier and check whether the circuit connection is loose.

Generally speaking, the power amplifier can be connected to the speaker through the speaker cable. When connecting, you should pay attention to whether the impedance of the speaker conforms to the output impedance of the power amplifier, so as not to affect the sound quality and the life of the power amplifier.
