  • Yamaha EMX200

    Looking for service info on this powered mixer. Mainly the protection circuit. Got one here randomly going into false protect.

    I don't have schematics for EMX series, but I am posting set for the EM200, with the hope that it will help somehow.

      My document inventory shows me as having it, but it is packed away, and may take some time to get to. However, if it helps googling, there is one manual for EMX150/200/300, so perhaps looking for the 150 might pay off.


      No... wait... it was on the shelf. Many pages, but here is the 150 power amp

        Thanks for the replies. I actually got this straightened out some time ago. The main pcb was full of cracked solder, causing the front end to freak out and trip the protection. Since pulling the main pcb looked like quite the PITA I really wanted documentation before I went hunting for the problem. But after I decided to yank it and have a look at the solder anyway it didn't take long to see what the problem was. Protection operates as it should now.
