Audio is: speakers, amplifiers, OK machine, microphone;
If you use in the home, is not a specialized audio-visual room, it is recommended that you do not get a professional audio, buy a set of home theater can be connected to the microphone on the line. As for the price and effect, depends on your own investment plan. Simply put, the room is large, the power to be high.
The TV is not to say, basically every family has. Projection is also possible.
Songwriting system: as long as there is a computer at home, to change the songwriter is very convenient.
Baidu "free song system", I personally use a barbaric song, the software is free to drop, the song can also be downloaded for free. The company's website is a great source of information about the company's products and services.
The whole thing, don't forget to give me points ha
