Amplifier and speaker power matching

September 02, 2022

Power matching between power amplifier and speaker in broadcasting system: In broadcasting system, the matching between Electronic amplifier and speaker is very particular. The connection between the Audio power amplifier and the speaker pays attention to suitable heat and cold, moderate hardness and softness, so as to maintain the neutral sound quality of the complete set of equipment, which is only considered at the modeling level. Power matching In order to meet the requirements of high-fidelity listening, the rated power should be determined according to the listening sound intensity. We often have such a feeling: the volume is small, the sound is weak, weak, dynamic, dull, lacking in high frequency, and the fullness is poor, and the sound seems to be curled up. When the volume is suitable, the sound is natural, clear, smooth, gentle and plump, powerful and dynamic. But when the volume is too loud, the sound is jerky, rough, and has a feeling of rooting in the ears. Therefore, the playback sound pressure level is closely related to the sound quality. The sound pressure level in the listening area is required to be 80~85dB (A-weighted). We can measure the distance from the listening area to the speaker and the characteristic sensitivity of the speaker. The rated power of the speaker and the rated power of the amplifier.
