Configuration problem of loudspeaker system in audio engineering

      Speaker system to high quality reproduction of various music programs, then according to the music signal properties, its peak factor is about 10-15DB, from the perspective of ensuring sound quality, power amplifier should be in this dynamic range without any limit, that is, the power amplifier output power should be 5-8 times the rated power, such a power configuration, although very good, but his investment will be great, so the power ratio will be set at 1-2 times the rated power.

　　The following is a general audio project configuration experience 　　

1、In some of the requirements of the low investment limited, the power of the power amplifier is equivalent to the rated power of the speaker. But to be very careful to keep sound without distortion. Too small power configuration does not appear to damage the speaker unit. Too small power is extremely easy to overload and cut off, resulting in a large number of harmonics, burning the high unit. 　　

2、The power of the power amplifier is 1.5 times as much as that of the power amplifier. The bass part of the best more than 1.5 times, so as to get enough strength.

3、High demand of the venue, such as recording studio *, music hall, etc., the ideal is two times the power of the speaker. (this is consistent with the standard recommended by the International Commission for Electrical Engineering (IEC).

 　　In short, there is no hard and fast design of the power amplifier, which depends on the investment budget and the quality of the requirements.
