How to identify good amplifiers through performance indicators!

The main performance indicators of professional power amplifiers include output power, frequency response, distortion, signal to noise ratio, output impedance, and damping coefficient. There are many performance indicators for an amplifier, but how do you identify a good amplifier from many indicators? Let's talk about it with the ceopa!

1. Music power: refers to the instantaneous maximum output power of the power amplifier to the music signal under the condition that the output distortion does not exceed the specified value.
2. Peak power: refers to the maximum music power that the power amplifier can output when the amplifier volume is adjusted to the maximum without distortion.
3. Rated output power: The average output power when the harmonic distortion is 10%. Also called the maximum useful power. Generally speaking, the peak power is greater than the music power, the music power is greater than the rated power, and generally the peak power is 5 times the rated power.
4. Frequency response: indicates the frequency range of the power amplifier and the unevenness in the frequency range. The straightness of the frequency response curve is generally expressed in decibels [db]. The frequency response of the power amplifier is generally 20Hz--20KHZ plus or minus 1db. The wider the range, the better. The frequency response of some of the best power amplifiers has been achieved 0--100KHZ.
5. Distortion: The ideal power amplifier should be the faithful reduction of the input signal after it has been changed without any change. However, for various reasons, the amplified signal of the power amplifier is compared with the input signal, and different degrees of distortion are often generated. This distortion is distortion. Expressed as a percentage, the smaller the value, the better. The total distortion of the amplifier is between 0.03% and -0.55%. The ceopa CE series professional amplifiers have achieved a total distortion of <0.05%, reaching the industry's leading level. The distortion of the power amplifier includes harmonic distortion, intermodulation distortion, cross distortion, clipping distortion, transient distortion, and transient intermodulation distortion.

6. Signal to noise ratio: refers to the ratio of the signal level to the various noise levels of the power amplifier output, expressed in db, the larger the value, the better. The signal-to-noise ratio of the general power amplifier is above 60db. The ceopa CE series professional power amplifier has achieved a signal-to-noise ratio of >98.2dB, which is in the leading position of the whole industry and shows the strong strength of the ceopa.
Conclusion
A power amplifier with strong performance indicators may not bring good results. Any one of the things that works well will exert its powerful strength. Therefore, if a good amplifier is used well, it must be made according to the actual situation. Change, can not stick to the rules, must be brave to innovate, in order to exert its powerful strength.
