I have a 24 channel mackie mixer with a nasty signal inside the left master and a minor signal in the right master. We tested the lines thru the solo function and all of the levels look gravy. Next we routed out the sub-outs and the sends... no problems there, signal is clean and pure with balanced levels on L/R. I took the bottom off and cleaned out the dust inside, but nothing major was there.
Unfortunately, the inside of the mackie 24-4 is made of three chips: two for the faders/knobs and one for the in/out on back. The power module is separated by some open box of aluminum with major power cables going to the boards right where mackie placed their cheap ribbon cables made of paper! One of the ribbons looks like it got hot while it sat near that power sink... imagine an IDE cable for your hard disc or cd-rom made from super-thin paper and super-thin wire!!!
Any ideas? I will be trying some fader cleaner. The ribbons on this model are soldered on the boards, so any work will be grueling! Thanks, mackie, but I won't be back! I heard your newer boards are made in China... no thanks.
