Can you tell me the difference between portable outdoor stereo's function of K store V and singing?

The difference between a square dance stereo and a karaoke stereo is the difference in sound and sound quality.

The square dance stereo is used in a larger space with a lot of people, so the amplification of the sound is the most important thing, and the sound should be big and no noise, so the sound effect is not too high requirements. k song stereo is used in a smaller area, and because of the need to highlight the singer's voice, the quality of the sound is very high requirements
