Ah ha. I had a loud hum through my subwoofer swarm for two months, I thought the Dayton amps were a problem, (recent thread on them not being able to find replacement parts). I had both amps plugged into the amp section of a Furman ref 20i. If I unhooked my usb from my server or dac the hum would no longer exist.
I finally decided to find this issue, the first thing I did was plug them into the other side of the conditioner and just like that the hum was gone. Try another outlet on your conditioner and you may be surprised!
Sub making electrical noises when connected to a Power conditioner
Hello,
I connected my sub to a power conditioner ( MPC 1500 by McIntosh ). The sub starts running hot with electrical noises from its amp on the back of it . ( no noise from the cone ). I noticed when there is no sound and literally when sub is powered on.
question: what does the conditioner do to the sub amp? I’m not even using by playing a track or anything - simply when turned on this starts happening . What does a conditioner do to power that causes the amp in sub to over heat even when not in use ?
since then I connected it directly to the wall and no heat or electrical noises .
