I've got a set of Mackie CR3s which the company sent to me when I warrantied my purchased set whose L/R selector corroded (was able to save that set by removing the component and hard-wiring).
The set they sent worked great for a few days, but I'm worried some direct sunlight heated them up too much (speculation) and now they only play incredibly quietly when on max-volume. Here's a video showcasing the problem.
I've tried different input sources, cables, switching L/R and only running the active speaker.
My electrical engineering skills are pretty limited but I'd love to learn and fix these if possible.
Thanks in advance for any help!
