OK, what's up guys/gals. I Did want to ask about 2-3 way summing from an audio control LC7i? What will summing do for the music? I'm not understanding the reason for it, so having it explained by someone other than a salesperson would be nice! I saw some diagrams of how to do it on the Audio Controls website, but it didn't explain what it will do for the music. If it could be answered by pointing me in the right forum, or here, I would greatly appreciate the assistance!
