Looks like they are claiming 10KW. I tested a Behringer inuke 6000 amp once that claimed 3,100 watts peak power per channel into 4 ohms. In reality, it put out 1,200 watts RMS per channel. When I spoke to them about it they said this very short term peak power rating was "common" for DJ applications and they were conforming to that tradition. In reality it was a very competent "lower" powered amp for only $400.

As far as running on a regular 120 VAC line, When living in MD, I was running my whole system including a true 5KW of amplifier power (two QSC 1310 and one Crown Macro Reference) on a shared 15 amp branch circuit. I never had a breaker trip because of the high peak to average nature of music, but I use a soft start circuit on my whole system to prevent turn on surges as all the storage caps in the different pieces charge up. If not, I'm sure I would trip the breaker.

In the current house, I'm running everything including over 7KW of amplifier power since I have added the distributed subs to the system powered by a Crown Studio Reference amp for a quad amped set up. It is on a dedicated 30 amp circuit and still goes through the soft start circuit. I'm including a photo of the equipment rack in the basement and the soft start circuit panel. It also has one power strip that is a straight on/off because some digital displays do not like a soft start. I'm including photos on the rack and soft start.

Bottom line on the original piece shown, I don't see it in my future.
