A gig I do regularly as a walk in (I bring some mics and my briefcase) they have an 8 year old Mackie 1604. It was new when the owner bought it and for most of it's life has lived in a slant top 14u rack. It doesn't travel (that is, it mostly lives in a back room at the venue) and gets set up once a week.
This spring we started getting dropouts from the left main TRS (only TRS outs on this desk). Wiggling something would get it back and most nights it would not come back. This has made it tough to isolate what was the issue. I swapped out the main snake with one of mine about 5 weeks ago and until last night had no drop outs. I was ready to do surgery on his snake.
Well, last night the left channel drops out though I can hear in the phones fine (and a look at the amp rack shows no signal) and so I spin the TRS for the left main out and it comes back and stays for the night.
I suspect it is oxidation on the connector? So, my plan is to take the mixer with me one night after the gig and open it up and replace the main out connectors. Is there something I can do from the outside without replacing the connectors?
Any suggestions on something else it could be?
I have not opened up one of these but a cursory look tells me it should not be too hard. I know the diagram in the manual shows it as a simple TRS but is it? I would like to buy the connectors before I open it up.
Thanks!!
