As a kind of household appliances with great individual differences, audio must be carefully listened to to compare its quality. So how to choose the audio?
The top five "fools" of audio sales
1. Selling dog meat on the head of "foreign" is obviously a domestic audio brand. In order to sell the product to "foreign price", it boasted that it was an international brand.
Demolition: In fact, more than 50% of the world ’s audio is made in China, most of the famous brands are made in China, and there are very few imported products. If it is, the price will certainly be higher There are many brands that choose to have a certain reputation in the world and are manufactured locally in China.
2. The promoter used paper to block the sound guide hole. When the speaker sounded, the paper would be broken to show that the sound effect was good.
Dismantling: As long as the exhaust of the audio has airflow, it does not mean that the audio is good or bad.
3. The optical fiber is automatically docked. When consumers are not paying attention, put a business card or a bank card between two optical fibers to prove that the optical fiber of the amplifier can be docked by itself, and the product is better.
Demolition tricks: General power amplifiers can be satisfied, do not believe you try.
4. No "howling". When the promoters demonstrate, they deliberately turn the microphone down, or block it with their hands, or reduce the delay and reverberation, and the sound will not "howl".
Dismantling: In fact, as long as the audio delay is too large, the echo is too large, the microphone and volume are too large, and the microphone will "howl" when it is facing the audio.
5. In order to prove the good shock absorption and stable performance of some speakers, some promoters put coins on the speaker upright, as long as they don't fall, they say the speaker is good.
Dismantling: In fact, as long as the speaker board is slightly thick enough, it will not fall, and the last speaker will not fall.
Shopping mistakes
1. The power of the amplifier is not as high as possible. It must be matched with the speaker. If the power is too large, the speaker will be damaged.
2. The price of the audio is not as expensive as possible, you should buy it according to your needs. The stereos purchased by consumers for different purposes are completely different.
Selection Guide Karaoke
If you are a karaoke enthusiast, you should pay attention to the sound effect to modify the singer's voice. When choosing, you should pay attention to the selection of all-digital, which is more realistic in terms of sound restoration. There must be two microphone interfaces on the amplifier, and the microphone itself is preferably digital and can be independently controlled. In addition, it should be noted that if you are pursuing the effect like in a movie theater, it is best to match a 6.1-channel home theater, where the power amplifier is preferably 6.1-channel, the difference from the 5.1-channel home theater is that there is an additional rear Set. This center sound hits the rear, and the sound sounds stronger. The real audiophiles use music to listen to music. They need to choose two speakers, a front center and two surrounds, which are commonly referred to as 5.1-channel audio. Generally speaking, speakers with a sensitivity above 20,000 yuan are relatively high, suitable for listening to music, but not suitable for singing karaoke. If you like to listen to classical music, try to choose European-made speakers, the tone is relatively soft. If consumers often listen to popular music and heavy metal music, it is suitable to choose speakers made in the United States and Canada. Generally speaking, such audio tones are relatively cold. The most basic rule is to choose a mix or familiar tune to test the sound. You can feel whether the sound from the sound is clean. At this time, don't let the promoters listen while listening, as this will affect your judgment.
