Problems solved by technology

The establishment and bonding of this kind of entertainment system is a relatively cumbersome process. There are many connections and need to be debugged. Non-professionals cannot operate at all, and it is difficult to achieve multi-function. The entertainment system used for singing and entertainment parties cannot realize video playback; the entertainment system used for meetings cannot realize entertainment functions before, during or after the meeting; the entertainment system used for video playback cannot be used to realize karaoke, small Temporary dance and other functions
