Magnetic Light Accessories Magnetic Track 1M,Led Rail Track,Led Track Rail,Magnetic Led Light Guangdong Decosun Lighting Technology Co.,Ltd , https://www.decosun-lighting.com This is a topic that has been debated for decades. Stereo enthusiasts have always felt that multi-channel home theater is a relatively low-level thing, and home theaters are simply not worth mentioning compared to high-end stereo systems that cost hundreds of thousands or even millions of dollars. It seems that stereo Hi-Fi is the best way to restore music effects. Is the multichannel system really not as good as stereo? Let us first take a look at the standard definition of stereo.
Stereo's original English name is "Stereo". Presumably, this word is familiar to everyone. You can see this word on many audio products. However, this word is actually an abbreviation of "Stereophonic", which is derived from the Greek word "stereos", meaning solid, three-dimensional. Everyone can be optimistic, here has never said that it is "two channels"! !
In the era of mono recording, recorded programs have been able to deliver important musical information such as melody, rhythm, tone and reverb. However, the sound field width, depth, and spatial envelopment cannot be achieved. Therefore, the scientists did a lot of scientific experiments in the 1930s. The experiment found that to achieve the sound field width, depth and space enveloping, at least two speakers are needed, and the audience must have only one person, when the audience deviates from the two speakers. At the axis, the sound field effect is greatly reduced, that is, the sound field collapses. I think everyone knows this.
How to solve the problem? The scientists tried to use three speakers, which are today's left, center and right speakers. The scientists were surprised to find that after the addition of the middle speaker, the emperor's area increased, even if it was a certain distance from the middle, the sound field effect heard was very good. Welcome to China Home Theater Decoration Network
Thus, the patent of the "Stereo" system shows that to achieve a good sound field effect, three speakers are an ideal choice. However, the LP film at that time could not record more than two channels of information, so the scientists had no choice but to choose two channels.
Please note that the two channels are the next best choice! ! LCR three channels is king! !
After reading this, you can make a phone call and laugh at your stubborn Hi-Fi friend. "Man, don't have two channels of Hi-Fi, burn it for a lifetime, you don't know that you burn less. A speaker?"
Speaking of this, I have to mention that, according to the principle of small room acoustics, the central axis of the room is the hardest hit area of ​​the low frequency standing wave, which is the trough of the 1/3/5 odd standing wave, 2/4/6 times. The peak of the secondary standing wave. Chinese houses are mostly reinforced concrete structures. This kind of hard wall will aggravate the influence of low-frequency standing waves (most of the houses in the United States are wooden keel structures, and the impact is much smaller). Two-channel enthusiasts especially like to sit in the middle of the room to enjoy the music (generally do not need to adjust the equalizer), this low-frequency effect, you can imagine. Four words to describe it, not to mention here.
Read this, you understand the truth, why two-channel enthusiasts especially like to listen to some medium-frequency but low-frequency music, such as female voices. That's because, when playing a big dynamic, low-frequency music, the effect is particularly bad. The huge low-frequency signal completely drowned the medium-high frequency, and the effect really couldn't be heard! ! Therefore, it is more comfortable to listen to something with less intermediate frequency and less low frequency. Written here, I really feel that those stubborn, equipment-oriented "stereo" enthusiasts are a little pitiful.
I have been to a stereo enthusiast's home, and the equipment is estimated to add more than 5 million. I used a super-top device like Wadia, but the actual sound quality effect really made the author crash. He used a pair of small-sized three-way speakers (the woofer is about 8 inches or 10 inches), and then placed it in a very empty living room. The living room floor is estimated to be more than 4 meters high and the area is about 70. Square meters, the living room is also connected to the restaurant and other spaces, the estimated actual acoustic area is more than 120 square meters. The sound, that is, no high frequency, no intermediate frequency, no low frequency, almost zero definition, no image at all. I would like to tell him, "Boss, this sound quality is really not as good as my family listening to the R1000TC North American version late at night, at least, my family's voice is very solid and clear."
Here have to praise the national brand rambler speaker, about 160 yuan price, the price is really nothing to say.
Since multi-channel systems are a better solution for music playback and restoration, why do stereo enthusiasts always say that multi-channel home theater systems play poorly? Please click here to enter
