Abstract
An amplifier system comprises an amplifier, a comparator connectable to the amplifier to compare an incoming signal with a number of reference potentials. A switching stage is controlled by the output of the comparator and arranged to select a voltage level to be applied to one side of a load, such as a loudspeaker system. A subtractor is included to subtract from the incoming signal a percentage of the selected voltage level to be applied to the load. The amplifier receives the output signal of the subtractor, amplifies that signal and applies it to a second side of the load. There is also disclosed a method for amplifying a signal.
