Hi everyone,
I have an older Mackie 808M powered head. It's been stored for quite a while, but we took it out and used it at a gig yesterday. It worked fine except for two things.
1. No monitor output. After playing with it a bit, I saw that it has signal showing up on the LEDs. And if I popped the microphone with my hand to get a peaking signal, that was audible in the monitor speakers. Both speaker output jacks behave the same way (tried it with different speakers as well). I'm wondering if it might just be a little corrosion on an internal spade connector or something. I have disassembled it, it looks clean but I'm going to just re-seat the cabling inside to the speakers. Is there anything else I should look for? By the way, we got through the gig by using the monitor line out and just ran that to another amp.
2. One of the channels is showing a peaking signal, and there's nothing plugged into that jack (all controls turned to zero). It's as if it's being overloaded but there's no signal there. I noticed it started doing it intermittently, and then eventually it stayed on constantly. I don't need that channel at the moment, but I hate to just throw in the towel if there's an easy fix. Also I worry that it might somehow damage other components.
Any suggestions are appreciated.
