What is the difference between DSP power amplifier and ordinary power amplifier?

Many people like music, whether it is KTV, home or car, our life is full of music, people's pursuit of music is getting higher and higher, so a power amplifier came into being, DSP amplifier.


1. What is a DSP?
DSP (Digital Signal Processing) is a unique microprocessor that uses digital signals to process large amounts of information. It works by receiving an analog signal and converting it to a digital signal of 0 or 1. The digital signal is modified, deleted, and enhanced, and the digital data is interpreted back into analog data or the actual environment format in other system chips.

2.DSP amplifier.
A simple understanding of DSP amplifiers is a power amplifier with a DSP chip. It not only has the function of power amplification of the audio signal by the ordinary power amplifier, but also has the function of digital effect processing on the audio signal.

3. The difference between DSP power amplifier and ordinary power amplifier.
There are a lot of expensive ordinary power amplifiers on the market. These power amplifiers are relatively stable and long-lasting, but there is still a distance from the DSP power amplifier. If the ordinary power amplifier wants to meet or exceed the sound quality of the DSP power amplifier, it needs an additional independent. DSP processor.

1) Ordinary power amplifiers can only adjust the gain, high and low pass, and can not be connected to the computer.
DSP power amplifier can be adjusted by computer, adjust the parameters of each channel (EQ, delay, crossover point, etc.), select the attenuation or add according to the environment, adjust the time of the speaker sound, and make the sound of all the speakers. It can reach the human ear at the same time and debug different frequency bands to achieve equalization and obtain lower distortion and better music.

2) The main function of the traditional power amplifier is power amplification. The functions of all traditional power amplifiers are not much different. The main differences are power, distortion, signal-to-noise ratio, control power and so on. In addition to the power to be amplified, the DSP power amplifier has basic functions such as sensitivity matching of the input, simple frequency division and low frequency enhancement. The function is more powerful and complicated.
The main function of DSP amplifiers is to process audio signals and amplify power. There are also many DSP amplifiers with multiple audio input functions. Thanks to the DSP function, it is not only basic sensitivity matching and simple crossover function in processing audio. For example, each channel independently adjusts the frequency division, EQ, delay, mute, phase, etc., which are standard functions, and the frequency division slope, frequency division type, and frequency division point all have multiple modes and precisions.

 

4. DSP amplifier advantages.
1) In terms of listening, the power of the DSP amplifier is very strong, and the power is really good. At the same time, the sound does not become very hard due to the powerful power, but a soft and resilient sound. In terms of music style, vocals, pop songs, and classical music can be easily mastered. Of course, due to the high power, big dynamic rock or dance music can also perform well.
2) It is not sensitive to the tolerance of component values, and is less affected by external factors such as temperature and environment;
3) It is convenient to adjust the coefficients of the processor to achieve adaptive filtering;
4) It can realize functions that cannot be realized by analog processing: linear phase, multi-sampling rate processing, cascading, easy storage, etc.
5) Can be used for signals with very low frequencies;
6) Easy to implement integration;
7) Tuning function, in the case of harsh environment, can use the tuning function to make up for it.

5. What problems can DSP amplifiers solve?
DSP amplifiers can solve common problems in many audio systems.
E.g:
►Sound localization problem,
►High-medium-low-tone levels are not clear,
►Sound turbidity problem,
►Sound field problem,
►Surrounding problem,
►The bass is dull, the power is insufficient, and so on.
