I was doing a party iconnect the mic to mixer, they star to talk paralell with music and blow the upper part of speakers, they sound but not any treble
What happened is that the tweeter is blown. or a fuse in the speaker that goes to the tweeter has blown. Hopefully that is it.
There are several causes. Here is the theory so you understand how to match an amplifier to a speaker system.
Tweeters have a much lower capacity for amplifier power then woofers do. All professional speakers as well as home speakers reflect this.
You may ask exactly what blew the tweeter?
Usually what destroys the tweeter is not amplifier power but distortion. If someone is overloading the microphone, or the microphone is not trimmed to the mixer. You get distortion. This distortion is what caused the tweeter to blow. The signal must be clean. If you put too much power in, it may survive OK but if you put distortion in, it will more likely blow.
It is no shame for this to happen. I have had it happen to me when mixing a live show. You just have to watch what is happening and not turn things up too loud so the mixer or the amplifier distorts.
Also when doing sound work, the ears of an engineer naturally lower the perception of loudness. Engineers often keep turning up the equipment up more and more during a performance because they have lost the perception of loudness that was there when they started. That is also the reason that many professional studio musicians and drummers loose much of their hearing at an early age.
Hope this helps,
