I have been considering purchasing one of these however I contacted Behringer regarding some simple questions I had.
Doing larger shows requires using a single phase 220vac distro which again require "Load Balancing" for each of the legs.
I inquired for the power consumption for their EP4000 and was told:
Now simple math tell me this in incorrect. The formula is voltage x current = wattage
At the plug the amp is fused as 15 amps while Jason boast of 2600 watts of power consumption.
15 amps x 120vac = 1800 watts leaving me with a deficit of 800 watts or 800 watts over the protective fusing.
The truth be told the actual 120vac current fusing for the load balancing needs to be 21.666 amps as stated by prosumer division of Behringer
These numbers also can be applied to the overall output of any class amplifiers output stage.
to achieve their rated output.
EPX4000 shows a required dedicated 30 amp circuit PEROID! 120vac x 30 amps = 3600 watts of actual power at the plug to support this class H amp. Please note this is NOT the suggested power input.
you can't starve this amp and expect it to perform. Most clubs and local places have at best 20amp service to each plug.
SO MY QUESTION IS THIS:
Are the Class H, and or D amps able to put out more power to the speaker then what is coming from
the House electric plug??
If yes, Then is this being performed using voltage doubling power supplies?
If yes then how much higher is the overall voltage from the amp to the speakers? and would this be damaging to your passive crossovers, speakers, especially HF horns.
The formula of voltage x current = wattage must apply

Dear 24volt,
Thank you for writing. For the EP4000, the 100-120V (US version) requires a 15 amp fuse (supplied). The power consumption for this model is 2600 watts. I am attaching the manual which has a spec sheet on page 12 as well.
Kind regards,
