I should be getting my new XPA-2 Friday. ;D I already have a UMC-200 and a XPA-3. I was wondering if I would be able to get the most out of my amps if they were both plugged into the same 20A circuit. I ran two dedicated 20A circuits to my entertainment center when I moved into my new place. I was planning to use one for my amps and the other for everything else. Oh, I will also have a BASH 500 plate amp for my subs that will be plugged into one of these as well. I will be using it to power two BFM Table Tubas, when I get them finished. I'll be wiring them in series to show the amp an 8 Ohm load, so it shouldn't pull too hard. What do you think about plugging all the amps on one dedicated 20A circuit.

You should be okay with both amps on the same circuit provided that you don't crank them to ear-bleeding levels. If it's a problem, the breaker will trip and you then know that you need to take one of the amps off that circuit. Go ahead and try it out, you have nothing to lose...

I agree. Doubtful you'll have any problems. If you do, a tripped breaker will be the only casualty.

I have an XPA-5 and XPA-2 plugged into a 15a circuit and have never had an issue.

2channon..Both of those units will be fine on a 20 amp circuit.You would have to max out the amps at full power and your ears would bleed before it would trip the breaker.

I have 2 xpa-2's and xpa-3 on a single 20amp no issues. I played loud to me music last night and not even close to tripping

Thanks to all for the reassurance. I wasn't even thinking about tripping the breaker...duh. I was concerned about supplying enough juice to the amps for them to function to their capabilities. I guess as long as I don't trip the breaker they will be getting all the juice they need. Thanks again.

I read somewhere that you shouldn't use a surge protector with these amps. They said that when they removed the surge protector and plugged their amp strait into the outlet that it was like removing a blanket from over their speakers. Does anyone have any experience with this?

You'll have no problem with both an XPA-2 & XPA-3 on a dedicated 20a circuit. Just for kicks I tried an XPR-2 and XPR-5 on one of my dedicated 20a circuits and I had no problems, though I've got them on different circuits now.

Same here. I had no problems cranking up Expendables 2 to ear-splitting levels with an XPR-5 on a single 20 amp. Of course, THAT is the ONLY thing on the circuit. Still think you'll be OK since (300 x 2) + (200 x 3) = 1200 watts. Even if you factor in 50% A/B efficiency, you'd have to be pretty-much " pegging " the amp all the time to even come close to the 2400 watt max of a 20 amp circuit.

Thanks again. ..I feel ya on this one and do understand the concerns.The "tripping the breaker" was added for some of the others who may not know.But yeah I fully understand your concern. |

They said that when they removed the surge protector and plugged their amp strait into the outlet that it was like removing a blanket from over their speakers. Does anyone have any experience with this? Surge Protectors should typically not constrain your amps (although Emotiva suggests plugging them straight into the wall anyway) and I have not experienced any issues with them. For example, my XPA-2 and XPA-5 are on a Belkin surge protector simply because the power cables weren't long enough to reach the 20A outlet I wanted to plug them into. My XPR-1s are straight into the wall (each on their own 20A circuit). I do have experience with power filtering devices that have constrained amps before though, so I would not recommend them for use with power amps. |

Well, you were right. I got it all hooked up today. I plugged both amps straight into the same outlet and watched X Men : First Class. Sounded GREAT! I set the UMC-200s volume on 53 for most of the movie...Perfect. Then did a little power listening with volume at 65, right at 100 dB, CLEAR and TIGHT. I have a perm-a-grin goin' on:P

At one point I ran dual XPA-1's plus an XPA-5 along with the rest of my gear on a single 15 amp circuit. Never did I once trip the breaker.

I am on a temporary setup until I finish my dedicated theater build. I probably shouldn't admit this, but I have 2x XPR1s plus an XPR-5 (center channel only, though) running on the same 15 amp circuit right now. At ear-splitting level, along with a TiVo, Apple Airport Express, Denon 4311ci (pre-amp only), OPPO BDP-95, and god knows what else might be on that circuit in another room - not the hint of a problem! Each XPR will be on a dedicated 20-amp circuit when the theater is finished, but I'm starting to suspect that these Emo amps can run on a 9v battery and a couple of paper clips  |

I am running a XPA-1 and a XPA-5 off a single 15 amp circuit the other XPA-1 and every thing else off another 15 amp circuit. When we have a party the XPA-1's can get pretty warm and never had a problem.
