After upgrading the car audio for the first time, many riders feel that the sound quality improvement is not obvious. The second time they come to the modification shop to upgrade the audio system, one problem that cannot be avoided is whether to install a DSP power amplifier or a power amplifier to improve the sound quality.Today, the editor of Dongjun car audio modification chain will answer this question.
DSP processor is a digital signal processor, a unique microprocessor, a device that processes a large amount of information with digital signals. Its working principle is to receive an analog signal and convert it into a digital signal of 0 or 1. The digital signal is then modified, deleted, enhanced, and interpreted in other SoCs back to analog data or real-world format. It is not only programmable, but also has a real-time running speed of tens of millions of complex instruction programs per second, far exceeding that of general-purpose microprocessors, and is an increasingly important computer chip in the digital electronic world.
The DSP processor can control the digital signal with a fixed program, use the strength of the frequency to create a sound field effect, and create a feeling of the auditory environment in a space such as an opera house. Or it can also modify the style of music into Jazz, Pop and other music types. Its powerful data processing capability and high operating speed are the two most commendable features.
Advantages: 1. The DSP module is integrated into the amplifier, which saves wire costs and wire interference, and saves installation space in the car. 2. The power amplifier with dsp function is very convenient to do active frequency division, delay processing, and EQ adjustment, which can improve the complex environment of the car and make the sound of the audio more durable and better!
Disadvantages: (1) Poor confidentiality: analog signal communication, especially microwave communication and wired open-line communication, is easy to be eavesdropped. As long as the analog signal is received, it is easy to get the communication content. (2) Weak anti-interference ability: The electrical signal will be interfered by various noises from the outside world and the inside of the communication system during the transmission process along the line. It is difficult to separate the noise and the signal after mixing, which reduces the communication quality. The longer the line, the more noise will accumulate.
The working principle of the power amplifier is to amplify the low-power signal into a high-power signal through the power amplifier, and it is a device that promotes the sound of the speaker. The power amplifier is designed and used to match the sound quality of the sound source, especially the digital sound source, it does not reduce the sound, on the contrary, it is particularly efficient, the power loss is very small, it is widely used, it can expand the system, make it upgrade, it is the sound An indispensable device for enthusiasts.
In addition to the basic car amplifier function, in the end, when the power is amplified, the sound quality should not be changed. This is the most basic premise and the value of the amplifier. Now people's pursuit of music is getting higher and higher. Dynamic stereo, surround sound, etc. are all realistic effects that people want to achieve, so car amplifiers are to achieve such effects.
Is it better to choose a good power amplifier or a DSP processor for the second upgrade of the car audio:
Compared with ordinary power amplifier, DSP processor obviously wins a lot. Ordinary power amplifiers can only adjust: gain, high and low pass, and cannot be connected to a computer. The DSP amplifier can better manage the amplifier through the computer.
Digital Signal Processing (DSP) technology has, is, and will play an integral role in it. The fusion of DSP and microprocessor will be one of the future development trends.
If you have high requirements on the sound quality of the original car and pursue the ultimate fever sound quality, it is recommended to install a separate power amplifier, which can show the most perfect sound of the speaker. A DSP processor with an internal power amplifier is also a good choice.
