Well, this mixer is working perfectly well now

I probably had an odd use case but this is working great for me

This mixer works great for this purpose

This worked perfect, even able to adjust the balance of each source so it sounds like it's coming from the correct monitor . =

This mixer works well for it

Simple, cheap, works well

The mixer works fine and I'm unable to reproduce the problems I was having before

This works great as expected PROVIDED that you plug it into enough power
