What's the difference between home theater stereo and KTV stereo?

1, supports different channels, and the power amplifier of home theater supports multiple channels, which can solve various surround effects such as 5. 1, 7. 1, 9. 1, so that each speaker can perform his own duties and have a clear division of labor.

2. Interfaces are different. There are many power amplifier interfaces in home theaters, which support optical fiber and coaxial interfaces in addition to ordinary speaker terminals. Can greatly improve the sound quality. The interface of karaoke power amplifier is relatively simple, generally only ordinary speaker terminals and red and white audio interfaces.

3. Different power, the power of karaoke amplifier is generally greater than that of home theater amplifier, mainly to match the power of karaoke speakers. Generally, there is no requirement for the decoding format of karaoke power amplifier when singing, as long as the power is enough.

Extended data:

How to deal with the sound field environment of home theater is actually how to do the acoustic design of a good listening room, and the following principles should be followed:

1, choose a suitable room ratio, or make the walls nonparallel, or increase diffusion, to avoid or reduce the influence of standing waves.

2. The reverberation time is appropriate to make the critical distance as far as possible.

3. Absorb the primary reflected sound to reduce the interference of the primary reflected sound to direct sound.

4. Try to absorb the sound. If the sound absorption can't meet the requirements, try to spread the reflected sound and make the sound field as uniform as possible.
