Does the square dance sound have 2, 1 channels?

The stereo used in the square dance is an outdoor stereo, that is, a battery that can be plugged in and charged, because sometimes the venue of the square dance has no electricity and can only rely on the battery in the stereo. Such stereos are generally available in electrical stores and online, and there are many brands. As for how big you choose, it depends on how many people are in your dance team. A dozen people can use small speakers with 2-inch speakers, within 200 yuan. 50 people use a 6-inch stereo. Don't turn up the volume too loud when playing, otherwise it will easily damage the speaker. When you buy a stereo, you must explain that it is used for outdoor square dancing, so that the merchant will understand that you want a rechargeable stereo. I hope my answer can help you.
