With Behringer, like most brands, be sure to download the manual and carefully review the specs. Behringer provides RMS numbers, which are significantly lower than the numbers posted on websites. However, all brands do this to some degree. For many you want to look at distortion numbers from 20 Hz to 20 kHz, which again will be lower than the touted power specs.
A man who has nothing which he is willing to fight for, nothing which he cares more about than he does about his personal safety, is a miserable creature who has no chance of being free.
