Question logic ?

maybe can I use somekind of logic circuits to communicate 30 input 20 output ?

Have standard bush buttons, and I have 4 sets of electronic circuits to drive 6 radios and 6 pair of speakers but the problem is that I can´t connect them together (I can´t switch the first one off when I bush the next circuit button )
HELP

a simple logic gate with a transistor output will do what you need and be quite inexpensive
