Is it better to install a DSP processor in the car audio modification or a better car amplifier?

After upgrading the car audio for the first time, many car users feel that the sound quality has not improved significantly. The second time they come to the modification shop to upgrade the audio system, one question that cannot be avoided is whether to improve the sound quality whether to install a DSP amplifier or add an amplifier.Today, Suoer car audio modification will answer this question.

 

What is a DSP processor:

 

The 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 to a digital signal of 0 or 1. Then modify, delete, and strengthen the digital signal, and interpret the digital data back to analog data or actual environment format in other system chips. It not only has programmability, but its real-time running speed can reach tens of millions of complex instruction programs per second, far surpassing general-purpose microprocessors, and it is an increasingly important computer chip in the digital electronic world.

 

The DSP processor can use a fixed program to control the digital signal, use the strength of the frequency to create a sound field effect, and create the auditory environment like 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 capabilities and high operating speed are the two most commendable features.

 

Advantages: 1. Integrate the DSP module into the amplifier, saving wire cost and wire interference, as well as saving installation space in the car. 2. The power amplifier with dsp function is very convenient for active crossover, delay processing, EQ tuning, so that the complex environment of the car can be improved, and the sound of the audio is more durable and better!

 

Disadvantages: (1) Poor confidentiality: Analog signal communications, especially microwave communications and wired open wire communications, are easily eavesdropped on. As long as the analog signal is received, the content of the communication can be easily obtained. (2) The anti-interference ability is weak: the electrical signal will be interfered by various noises from the outside and the communication system during the transmission along the line, and it is difficult to separate the noise and the signal after mixing, which will reduce the communication quality. The longer the line, the more noise will accumulate.

 

What is a car amplifier:

 

The working principle of the car amplifier is a device that amplifies the low power signal into a high power signal through the car amplifier and drives the speaker to sound. The design and use of the car amplifier is to match the sound quality of the sound source, especially the digital sound source, it will not reduce the sound, on the contrary, the efficiency is particularly high, the power loss is small, it is widely used, and the system can be expanded and upgraded. It is a sound Indispensable equipment for hobbyists.

 

In addition to the basic car amplification function, it is ultimately necessary to prevent the sound quality from changing when the power is amplified. This is the most basic premise and the value of the amplifier. Nowadays, 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.

 

In the second upgrade of car audio, it is better to choose a better amplifier or a DSP processor:

 

Compared with ordinary power amplifiers, DSP processors clearly outperform a lot. Ordinary power amplifier can only be adjusted: gain, high and low pass, and cannot be connected to the computer. The DSP power amplifier can better manage the power amplifier through the computer.

 

Digital signal processing (DSP) technology has, is, and will play an indispensable role in it. The fusion of DSP and microprocessor will be one of the future development trends.

 

If the sound quality requirements of the original car are relatively high, and the pursuit of the ultimate fever sound quality, it is still recommended to install a separate power amplifier, which can show the most perfect sound of the speaker. If it is only a change from the original sound quality and the budget is limited, install it. A DSP processor with an internal power amplifier is also a good choice.
