Amplifier and DSP
As a more and more popular means of transportation, cars have occupied more time and space for human beings and have become an indispensable daily necessity. As the only part with entertainment function in this driving tool, the original car audio sometimes cannot meet the needs of some drivers who have high requirements for music, so car audio modification has become a more important thing.
1. Car audio amplifier The power amplifier is also called the power amplifier, which is responsible for amplifying the power of the front-stage audio signal and then driving the speaker. Most of the power amplifiers built into the host generally have very small output power, and their sound quality cannot be compared with that of external power amplifiers. If you want better sound quality or drive a higher-power speaker, adding a power amplifier is indispensable. Power amplifiers can be divided into Class A power amplifiers, Class AB power amplifiers, and Class B power amplifiers according to their structure. If they are divided into single-channel power amplifiers, two-channel power amplifiers, three-channel power amplifiers, four-channel power amplifiers, and five-channel power amplifiers according to the number of channels.
2. Car Audio DSP Processor DSP amplifier, also called DSP digital amplifier, uses DSP chip, which can adjust the parameters of each channel through computer. The biggest difference from traditional amplifier is that DSP amplifier can be better managed through computer, while traditional amplifier cannot do this. DSP amplifier has the functions of other amplifiers, and can also attenuate the overlapping frequencies caused by the car environment, and the attenuated frequencies can be added, and can also adjust the distance between each speaker in the car and the human ear. DSP amplifier mainly has delay processing, EQ adjustment function, and frequency division function. It can adjust the defects in the car that cannot be adjusted physically, and completely improve the complex audio environment in the car, making the sound quality clear.
What are stereo and surround soundCar owners often complain that after changing the speakers, they cannot hear surround sound in the car, or there is no stereoscopic effect. After further communication, you will find that many car enthusiasts have no basic concep
How is the tone of the tube amplifier formed? Many enthusiasts like the sound of tube amps (also called vacuum tube amplifiers): warm and mellow, not unpleasant, not shocking, and soothing. People call this taste the smell of bile. The author has been playing with tube amps for decades and has
What is stereo audio? What is the difference between mono and surround sound?Stereo audio has been the dominant format for analog or digital audio in the music industry for decades. It's a relatively simple format that does a good job of simulating the way we naturally hear the world around us, and
合并式胆机还需要再加一个前级吗?很多烧友都有这样的疑问。这里有三个因素,一是音源输出的讯号是否大?很多外国CD机输出讯号偏小,加台前级可以放大讯号。二是音箱的灵敏度,灵敏度在90dB以下的音箱,加台前级,声音的表现会更好。三是胆机的放大量,增益30dB的标准合并式胆机,对输入讯号的放大量约15倍左右。而增益为20dB的合并式胆机,放大量约10倍,略显不足,动态会有欠缺。如果你对声音有很高的要求,最好再添一台前级做配套,将合并功放作为后级用。前级可以增10倍放大量,两台机加起来增益可达40dB。这时候,后级会推得更轻松、声音密度高、细节丰富、瞬态更强,音响系统的表现就非常完美了。
The basic composition of the listening system and the selection of amplifiers and speakersBasic components of a listening systemFirst, let’s talk about the composition of a complete system. Simply put, it can basically consist of the following three parts:Audio source, amplifier, speakers.Sound sour
What is an AV amplifierThe A (audio) of the AV amplifier represents audio and sound, and the V (video) represents audio and image. Therefore, the AV amplifier is an audio-visual amplifier that combines audio and video signal processing. It emphasizes the atmo
About--Basic knowledge of power amplifiersThe working principle of the power amplifier is actually very simple. Intuitively, it amplifies various sound signals played by the audio source to push the speaker to produce sound. From a technical point of view, a power amplifier is like a current modulat
