Hey everyone. So I started to gain mod my DMIC-20 and got to a point that I kind of got over my head. A board member here agreed to finish the mod out of the goodness of his heart, for which I am very grateful. So I got it back tested it out on the home system, and ran it for a show. Eveything seemed to work great. I ended up selling it and the person who bought it said that they had a problem with one of the channels dropping 30dB. I got it back at home and Im doing some testing and Im showing idenitical levels. Im not accusing the person who bought it of anything, I have every reason to believe that he was telling the truth, so I definitely want to get to the bottom of this becuase I really can afford to not sell this thing... Now, I had put the burr brown IC chips, and he said that he switched them (left channel chip to right and vice versa) and it worked for a little bit and then it dropped back down again... I really need some help, becuase Im not much of electroncs guy.. Do you think that this could be because of the IC chips or do you think it would be because of the gain mod? Can anyone help me out? If anyone needs more details, please please let me know!
