The speaker system needs to reproduce various music programs with high quality. According to the properties of the music signal, the peak factor is about 10-15DB. From the perspective of ensuring sound quality, the power amplifier should not have any clipping in this dynamic range. , That is, the maximum output power of the power amplifier should be 5-8 times the rated power of the speaker. Although the sound quality of such a power configuration is very good, his investment will be large, so this power ratio is generally set at 1-2 times the speaker The power rating of the unit.
The following is the configuration experience in general audio engineering
1. In some projects with low requirements and limited investment, the power of the power amplifier is at least equivalent to the rated power of the speaker. But be very careful to keep the sound undistorted. A power configuration that is too small does not seem to damage the speaker unit, but it is not. Too small power is extremely prone to overload clipping, which generates a lot of harmonics and burns the tweeter.
2. The power recommended by the general project is 1.5 times. The bass part is better than 1.5 times, so as to obtain a sufficient sense of power.
3. The most demanding venues, such as recording studios *, concert halls, etc., are ideally twice the power of the speakers. (This is consistent with one of the recommended values ​​of the mating standard developed by the International Electrotechnical Commission IEC).
In short, there is no hard standard for the design of power amplifier power, which depends entirely on the investment budget and the requirements for sound quality.
