Configuration of loudspeaker system in audio engineering

2023 01/10

If the PA Loudspeaker system wants to reproduce various music programs with high quality, its peak factor according to the nature of the music signal. From the perspective of ensuring sound quality, the power amplifier should not have any amplitude limitation in this dynamic range, that is, the output power of the power amplifier should be 5-8 times the rated power of the speaker. Although the sound quality of this power configuration is very good, his investment will be great.

The following is the configuration experience in general audio engineering.

1. In some projects with low requirements and limited investment, the power of power amplifier is at least equal to the rated power of loudspeaker. But be very careful to keep the sound undistorted. Too small a power configuration does not seem to damage the speaker, but it is not. Too low power is easy to overload clipping, generate a large number of harmonics, and burn out the treble.

2. Generally, the power of PA Amplifier is recommended to be 1.5 times. The bass part should be more than 1.5 times, so as to get enough strength.


3. Required venues, such as recording studio, concert hall, etc. Ideally, there should be twice the horn speaker power. (This is consistent with one of the recommended values of the IEC standard of the Electrotechnical Commission).

In short, there is no rigid standard for the design of power amplifier. It depends on the investment budget and the requirements for sound quality.
