I need pa equipment that will be good and i can stick with them for a while so i need 2 speakers,a power amp, sound board, multieffect processor,cables, mics? Is the multi effect processor an equalizor also? And i still dont know what to exactly get before i plug my amp into the soundboard.

I am thinking about getting 2 peavey 15" speakers that are 1000 a piece. if i am gonna have a trio band what type of soundboard should iget where also my drummer can mic up also?
