Hi, I'm new to Emotiva, and I've jumped in the deep end. I'm almost done putting together a home theater with Emotiva gear doing the heavy audio lifting. Today I finally got around to installing my gear into the equipment rack, and I decided to check the manual and came across this line:  If I'm good at anything, I'm good at overkill. I had a hunch when I built the theater that I might want to run some amps, or computer equipment at 220v so I ran 4 seperate 10 AWG lines to my rack, and left space in the breaker box to swap to 220v breakers if necessary. But until I read the manual today, I hadn't found anything that suggested one way was better than the other. This line in the manual makes me wonder should I swap to 220v? Anyway enough about my situation, back to the real question: What does this line in the manual actually mean? Absolute ultimate? Would two amps be better served on individual 120v circuits, or sharing a 220v circuit? What about processors? Any difference 120v 220v? Anyway .. attaching a couple progress photos from today. I can't wait to get to using all this great gear! I've got the RMC-1 for processing, and a XPA-DR3 for the fronts, and XPA-8 Gen 3 for the rest of the channels. Attachments:

Since you can easily run 220 to the amps I would say go for it. At 110 the outlet cannot provide as much juice as the power supply can pull. I doubt that you'd ever tax the amps, even at 110, but overkill is a good thing isn't it? That said, I'd run both XPA's on one 220 circuit.
The preamp is fine at 110 since it's power requirements are so small.

Your system is looking awesome. I'd sure recommend putting about 4u space between the XPA amps though. You have plenty of room, so no sense cooking the upper amp.

I'm still considering the spacing.. the rack closet has active temp controlled exhaust, and a duct from the AC. I really like how they look when right next to each other, but I obviously don't want to cook them. I've only just started populating the rack, I still owe some kind of HTPC and a NAS above the amps, and a Zone 2 amp below (still looking for the right one, maybe the A-800 although it's not quite exactly what I need) so Im hoping to be as efficient as possible w/ spacing to allow room for growth. |

The preamp is fine at 110 since it's power requirements are so small. I was thinking last night, I could also use the white wire in the circuits as the second hot and run two 220v lines, one per amp. I just wonder if I'm going past the point of actual gains. My original wiring had all audio equipment on the same phase, this plan would change that, but again I'm not sure if that mattered either. |

Use the 120V.
I see more problems here on the forum related to 220V and Emotive gearthan anything else.
Why take the chance?

I haven’t heard any reports of issues here (in Australia) where we all have 220/240 volts. Personally, over the last 10 years or so, I’m up to 12 pieces of Emotiva gear and the only one with an issue was the UMC-200. Which was a common problem, whether feed 110 or 220 volts, fixed by the same board swap. Far more of the world runs on 220/240 volts than 110 volts, around 80%, so if Emotiva gear has a problem with 220/240 then we (and Emotiva) would know about it big time. Cheers Gary |

I had hesitated to post my reply, but I stand by my assertion. Its a recurring theme, granted many countries in the world and it may be country specific.
I've been on the forum since the XDA-1 days and in this spot I'd stay 120V since I could.

Use the supply that is most readily available with the least amount of modification.
The option is there for the greatest amount of install flexibility but there is no meaningful performance difference in audio by going either way.

If you have all the outlets in 115VAC properly divided between the two line legs you probably won't hear a difference or encounter any problems.
