Had another question but wanted to change that last far off topic thread...
The JBL Eon 15Ps im using are so loud that I dont really need to run through my mixer, is it OK to just use one cable from L/mono on the keyboard to the speaker, and do the same for the other keyboard, so each speaker controls a keyboard and its in mono? I'm going to be competing with heavy guitars, bass and drums so the stereo sound isnt that important right? And the speakers will be within 2-3 feet of each other on stage...
