200 square meters to make a hall? Is this still called KTV? If you really do it according to the KTV effect, it will be too wasteful; Personally, I think it should be made into a professional effect hall; There can also be a small performance stage; Plus professional lighting effects; Guaranteed to be better than KTV you said. . .

Equipment list:

Sound box; Single 12 full frequency 2 pairs; Single 10 full-frequency 2 pairs (a pair of stage listening and a pair of rear-mounted) (whether a center speaker is needed as appropriate) A pair of bass speakers with double18; Single pair18;

Power amplifier; According to the number of conventional speakers (the power must be 1.2 to 1.5 times higher than the speakers).

Mixer; Pure platform; 10 road is enough;

Equalizer; Double 3 1 segment professional balance

Effector; Professional effect device; It's not a KTV stereo.

Wireless microphone; A set; High frequency; Adjustable frequency

Frequency divider; Used for bass frequency division;

Song ordering system; a set

Lighting; Computer shake head light; LED parking light; Wizard lamp; Laser lights, etc.

As long as the above equipment is properly matched; Don't choose the same brand; Debugging must be completed by professionals; This professional effect is not comparable to KTV; Because a major is a major. . . .
