How to use the amplifier?

The operation of power amplifiers is relatively simple. Professional power amplifiers usually only have power switches and volume control knobs. When using them, be careful not to turn the volume too high, otherwise it is easy to overload the power, produce harmonic distortion, and cause damage to the speaker's tweeter unit. When matching amplifiers and speakers, attention should be paid to the matching of impedance and power. Under the same impedance, the output power of the amplifier is generally 1.5 to 2 times the rated power of the speaker, which is more appropriate. A reasonable match between impedance and power can ensure that the sound is not distorted while also ensuring the safety of the speaker. There are generally three connection methods for amplifiers: stereo, parallel, and bridge. When connecting the amplifier to the speaker, attention should be paid to distinguishing between positive and negative poles. The positive pole must be connected to the positive pole, and the negative pole must be connected to the negative pole. Otherwise, the speaker's phase is incorrect, and the sound will cancel out each other, resulting in a decrease in the sound coming out of the speaker.
