I have a Mackie 1604 vzl pro mixer. It has two weak channels and a non working channel. Could give some tips on what I should look for when open up the unit?
First, unless you are a trained or self-taught audio technician, don't attempt to repair the unit yourself. Let the professionals repair it. You can damage it beyond repair if you don't know what you're doing.
Non-working channels are caused either by bad connections, bad solder joints or a dead IC op-amp.
The causes of weak channels can be more challenging to track down. I'd suspect bad connections, dirty controls or connectors.
