Home theater KTV audio system, generally using karaoke customized karaoke power amplifier and speakers (professional speakers or card pack speakers) can complete the adjustment and beautification of human voices.
There are some low prices in the market, claiming that the sound is super good, so you should be very careful when purchasing. Basically, it is a product that is not in line with the board. In short, it is cheap but not good, so it is necessary to know some knowledge of buying KTV audio.
Home theater KTV audio procurement skills:
1. Pay attention to whether the sound quality of the audio output is even (it is best to be slightly prominent in the midrange). If the high frequency is not enough, the human voice will not come out and it will be difficult to sing. In short, the base sound is very sinking. It is round and elastic, with bright midrange and fine treble and not harsh. It is a good speaker.
2. Pay attention to the sound field environment of the home theater. If it is independent. The film and television hall has good sound insulation, you can purchase a professional audio system with high power, including pre-level effects, high-power rear amplifiers and large specifications. The price of a high-powered audio set of this grade is basically around 10,000 to 20,000 yuan; if used in the living room of an ordinary house, due to space limitations and disturbances, it is recommended to use a combined power amplifier and a card-pack speaker with low power. Generally speaking, you can get it for about 5,000 or 6,000 yuan;
In recent years, there has been a KTV audio system that is very popular, namely an integrated KTV multi-function entertainment system, which is actually a power amplifier, effect device, and microphone integrated audio system, but it is generally not very powerful, but it is very convenient to use, and is not restricted by the indoor environment, and the price is about 6,000 yuan. Suggestion: The power amplifier of the KTV system in general home theater is 100 watts to 300 watts, and the film and television hall is about 25 square meters. The power amplifier is suitable for the film and television hall with a power of about 450 watts per square meter. 650 watts are required.
3. Pay attention to the dynamic amplification degree of the audio domain, that is, when the customer amplifies the sound of the speaker device and exceeds a certain limit, whether the audio can maintain a symmetric and clear sound source signal amplification capability (no sound) throughout the audio area.
4. Pay attention to the power matching of the power amplifier and speakers. Generally speaking, when the output impedance is the same, it is better for the output power of the power amplifier to be 1.8-2 times the output power of the speaker.
