Hello, I'm new to these forums, and I'm trying to find a solution to my problem. Here goes nothing! I have an analogic console "Soundcraft Spirit M-12", 2 sound monitors "Tannoy Reveal 5a" and a 15" Macbook pro. With my mate we're trying to set up everything for the party, but when we came to the sound checking, we heard noise. I tested everything and found out that the noise is hearable only from either the laptop or the mini jack-ins. This Monday I'll go buy new mini jack-ins to test if the cables are the problem themselves, however, I'm fearing for the worst that the laptop might be the problem itself producing noise. Is there a way to get rid of the noise? Thanks kindly!
