Problem With E15HP

[racrawford65]

Good idea, N Boros. Although the OP did try a different room/circuit he still had the hum. However, from what you wrote, it may still be introduced from a different room/circuit/appliance and is impacting more than 1 room.

I guess I was too quick to discount poor electrical wiring or another misbehaving appliance. Definitely could cause a power related hum. Hopefully circuit isolation helps with identifying the problem. If not then a product like Hum X potentially could help.

I'll add in my own experience here. While I did not have the issue described with my Rythmik subs, I did have a buzzing from an amplifier toroidal transformer. I added a DC blocking device (Van Alstine Humdinger) between the outlet and the amplifier power cord and that did the trick. Since the Rythmik amps (Not the class D version, however) have a good sized toroidal transformer, I wonder if that would help. I believe SVS sells another version of the DC blocker.

Thanks for posting that Van Alstine device, Ed.

Emotiva (if you dare ;-)) and iFi have similar devices that I found doing a quick search.

Ah, that's the one! I get Emotiva and SVS crossed up sometimes, thanks!

No worries. I checked SVS's site but didn't see anything similar. And it gave me the opportunity to discover the iFi version, should I ever need something like this (since I'm no longer an Emotiva fan)

While that iFi looks nice, and is compact, it is for a single component. The Van Alstine Humdinger is slightly more expensive, but it handles 2 power cords and would be considerably less expensive vs needing 2 of those!
