Hi, I've got a Mackie 1604-VLZ in my workshop for repair.
The Solos don't mute the other channels, there's no left-hand-side from either the main outs or the ctrl rm outs (or present on the main level indicator lights), solos don't do anything when using the main outs, and when on ctrl rm outs, the LHS works when on PFL but not AFL. (still no muting of other channels when a channel is soloed, but level indicator lights work too in this mode).
It does look as if someone's thrown up inside the box on the 1st 2 channels so I'm going to clean this up and check the components as there could be some heat/liquid damage here under the gunk.
I've got a feeling that there's 2 main problems - the left pan assign controller and the solo controllers. I'm going to start by cleaning them up with some switch cleaner and get a DMM across them to see what's going on, but I don't have a schematic unfortunately so it could be a slow process.
I've got the user manual etc from the Mackie Website, but there's no schematic with it, just a block signal flow diagram.
Does anyone have a wiring diagram for this mixer?
Here's hoping,
Phil
