Home Theater Network () When you are ready to buy a set of audio for yourself, do you believe in advertising, shopping guides, or your own ears? Remember, your ears are also deceived. When the guide is playing a song for you, do you suspect your ears when you are moving the realistic vocals, glass breaks, and heavy bass in the speakers? Can you still ask questions about the sound in front of you? If you decide to buy at this moment, I can tell you! Your decision is often wrong (I mean "often"). Because the shopping guide is misleading you, this is a promotional method used by audio guides. They are playing a disc with special sound effects (may be burned, but the sound is as confusing). Even a very bad sound can play this effect, and the import of large DVD clips, etc., is equally deceptive.
What kind of sound is a good sound? Is the price high? Is it good to be famous brand (a domestic joint venture brand, the actual audition of the glasses)? All the functions are good? Advanced will be good (24bit- If there is no rigorous peripheral circuit protection, 192khz may also make a very bad product. On the contrary, 16bit-44.1khz is still doing the top secret.) Is it digital? (The digital d-class power amplifier is mediocre, it is obvious to all) Eye, hand touch, ear (most important), based on living environment and economic affordability and personal preferences for reference. To listen to music, you have to buy pure power amplifiers. When you watch movies, you have to buy a home theater amplifier. If you choose carefully, you can also have both fish and bear's paw. The living room is used to buy floor-standing speakers, and the study room is used to buy bookshelf speakers. The appearance of fashion is not necessarily good quality, the stylish appearance can only please those who are good-looking. Of course, if you can do both internal and external repairs, good quality and good appearance will be better.
Buy the audio and remember to bring the film you are familiar with (normal CD can be, it is best to be genuine or HDCD of a certain company in Shenzhen, I tried, the quality is good). Look at the power amplifier manual, preferably with decoding (ie digital interface: such as fiber, USB, coaxial input), and some only analog interface with decoding, I do not understand, since it is analog input, with the use of decoding, There is suspicion. Amplifier with decoding can avoid the uncertainty of DVD or CD sound quality. Most popular DVD or CD sound quality is not flattering. Turn on the power supply of the power amplifier. After a few minutes, the temperature of the hand-mode housing is better (indicating that the quiescent current of the power amplifier is larger, and the temperature of the pure power amplifier housing is higher). Looking through the heat-dissipating window, can you see the huge transformer and capacitor ( I don't know the weight of the handcuffs, but it is usually better.)
Speaker selection is also very particular about the shell material, there are logs, high-density board skin, plastic, speaker unit imported, domestic, magnetic shielding, double magnet, single magnetic, alloy ferromagnetic, There are rare earth magnets. The paper cones are made of chemical fiber, paper, wool, and many materials. The structure has a floor box, a bookshelf box, a side bass, a side bass, a subwoofer, a back bass, a crossover network with two, three, and many crossovers, usually a log speaker (someone) Think that the log speaker is not as good as the high-density board speaker, but the price is definitely a lot more expensive in the original wooden box), anti-magnetic dual-magnetic speaker unit (especially computer speakers), wool paper cone, subwoofer, three-way divider is better. Can be purchased according to personal preferences and economic conditions. Generally, the structure is compact, rigorous, balanced, and has no obvious appearance. As long as the materials are packed in the box, you can't see it, you can only use your golden ear to accept. But I personally think that the power amplifier is the basis of a set of speakers. There is no good power amplifier. No matter how good the speaker is, it is useless. The power amplifier itself is full of noise and distortion. What is the best speaker? The so-called: So, for the active head to come to the water." Therefore, please be cautious when purchasing expensive speakers, so as not to be murdered by money (the high-quality amplifiers themselves are of first-class quality, but it is just that the speakers are not enough). On the contrary, a good amplifier can be used in conjunction with a normal speaker. Of course, if the professional matching effect is better, but advanced sound and sound equipment and rich experience are needed.
Next is the most critical stage of ear acceptance. First connect the Fiber Optic Cable or other interface, maximize the volume of the amplifier, and maximize the volume of the DVD or CD (remember to pause the DVD or CD first, otherwise Beware of your ears), put your ears close to the speakers, and you should not hear any sound coming out of the speakers. This proves that the amplifier you want has a sufficient signal-to-noise ratio (the amplifier with a 1-bit decoder chip is especially important). Turn off the small volume potentiometer, play the music you are familiar with (the film is better, there are violin, middle drum, piano, vocals, symphony, etc., but don't use the professionally processed audition discs), slowly taste . Not to be humble. It is not soft or hard, the treble is delicate and sultry, the midrange is full and wide, the bass is strong and deep, and the strings are smooth and hairless. Those renderings that are too high and too high are not right. Sometimes you may be attracted by exaggerated sounds, but listening for a long time is boring, harsh, and annoying. This is the difference between good and bad sounds. Making music, poor sound makes music while making noise.
When you find that the music that you don't usually think is really clear and bright, you can't stop it. When you hear the sound you can't hear, it's right. Good sound is very resistant, the more you listen, the better you listen, the female voice is soeping, the male voice is bright and mellow, the child voice is like a small hand to caress your skin, the string is like a big bead and a jade plate, the wind is straight into the sky, the blow It’s like a rush of water until the ear hole is oily.
My personal experience made me appreciate the infinite charm of good sound. Last year, I spent less money to buy a certain brand of audio and went home to pick up the fine line. I just visited the female colleague that night, talking about the sound and tunneling. A song sung by Anita Mui started to broadcast "I love you thousands of times in a lifetime" and then broadcast "Think of it" and "Daughter Red". The female colleague turned his face and broadcasted the "woman flower" when he finished watching the female colleague. Tears burst into tears and wept. Afterwards, she told me that she had never been so touched by music for more than ten years. Mei Yanfang’s delicate voice was like talking in her ear. The sound of the instrument with very fine background was clear and identifiable. The atmosphere was very good. She was also a woman, she really wanted to cry. One. I am at a loss!
If you want to have a good sound, please use your heart and soul to choose, I believe that there will be more elegant friends in life. More home theater shopping tips, welcome to pay attention to the home theater network official WeChat: cnhifi.
