You also want to home run both neutral and line conductors from the receptacle back to the panel. Most home wiring circuits share neutrals, so you will get feedback from lighting circuits. Florescent are horrible…


Interesting... If there was feedback, what would it sound like?

Oh, That's different from the WAF feedback one might usually here with HT! \:D

I occasionally (not often) hear popping and buzz for ≈ 3 seconds from one sub and my computer speakers. They are on a different circuit than the HT. I will try to relate it to an electrical ocurance (like fridge turns on, etc.), next time.

Seriously, would the feed back be more consistant than intermitant?
(or is that inter mutant)

.... Rick, OK which is it? Bzzzzzzz or \:D . They are very different 'feedbacks'! (but Rick, your 'feedback' is always welcome. ;\) )

Dave, if you have a ground loop problem it would be a constant humming or buzzing sound. Here is Alan's article on ground loops.

Rick,
Oh, now I remember now. I had that on my boat stereo and it was constant. Thanks for the reminder.

Well, I checked all the draws on the circuit with my HT. No fridge, but LOTS of lights plus an early 90's 52" DLP AND a room/window A/C unit which will run occasionally in the summer.

Dedicated 20 amp circuit for HT is now on the to do list. (way down, but on it! ;\) )
