A Behringer EP 2500 amp is essentially a class A/B amplifier. It is a class H amp. A Class G or Class H amplifier is essentially a Class AB amp on steroids. And this is where we start talking about voltage rails. The voltage rail is the amount of voltage allowed or produced by the power supply. It's typically something that is "set". A Class G amplifier is an amp that acknowledges the need for extra power when the signal calls for it. When the peaks of the output signal exceed the main voltage rail, the amp switches the output signal to a secondary higher voltage rail and handles the load. This allows Class G amplifiers to operate at higher Class AB efficiency, but also provide for larger peaks as needed without having to raise the voltage rail across the board.
A Class H amplifier is very similar, but it monitors the voltage on the input side and adjusts the supply rail voltage as needed, allowing for handling of peaks.
