My EP500 Sub arrived yesterday, which was good timing because I only just finished installing the QS8s that had arrived with the rest of my Epic 80 system on Monday.
Anyway, I switched on the system last night for the first time with everything connected (which was previously working just fine with only the fronts and center speakers) only to find very loud mains hum coming from all the speakers!!!!
Luckily, I had actually read the sub woofer manual before setting it up, so rather than spending hours isolating the problem, I just removed the Chassis Grounding screw, as instructed, from the sub and that solved the problem!!!
It was funny, I was holding onto the screw when we powered the system up again, and both my wife and I had absolutely no confidence that this would solve the problem.
