After much research, I am planning to buy a P12 for the dedicated listening room. But before I do, I have a few questions.
I live in Asia, specially the Philippines. Mains voltage here is 220V and most receptacles are two-prong. To get 110V, electricians simply wire one prong to one mains leg, and the other prong to the home ground rod with THWN cable alongside the mains cable.
The 220V version of the P12 is available here, and I hope you don’t mind if I have some country-specific questions.
-
Given the mains configuration here, how effective will the P12 be?
-
Changing the receptacles from 2-prong to 3-prong will be an easy job for the electrician because the home ground rod happens to be just outside the listening room. All he has to do, aside from installing the new 3-prong receptacles, will be to run a proper THWN wire from the home ground rod to the third prong alongside the mains cables. Once in place, that’s where I’ll plug in the P12. Will this benefit the P12?
-
The main circuit breaker panel in my home is under 40 feet away from the listening room. In it is a spare, unused 20A breaker. Instead of the P12 getting power from an outlet, the electrician can simple run new THWN cables from the unused breaker and terminate it with a new female IEC plug. That will directly feed the P12. Will doing this benefit the P12?
-
If there are benefits to doing no. 3 above, should I still ask the electrician to run an additional THWN cable from the home ground rod, alongside the current-carrying cables, to the ground prong of the female IEC plug that will feed the P12?
And one question that isn’t specific to the mains configuration in my country…
- All my source components and preamp are on a rack against the left wall of my listening room. The speakers are around 10 feet away from the listening chair and only thing near them is the power amp on a low stand. I arranged my gear this way because I prefer to have nothing near the speakers that can affect how it sounds. Both the preamp and the power amp are balanced differential, so I use long XLR cables connect them. I have confirmed that the power needs of all my gear are well within the capability of the P12. Where will be the best location for the P12 in my room?
Thanks in advance!
