 reactive element. A low signal level detector is coupled to the second pair of transistor switches for disabling the second pair of transistor switches from switching upon detection of a low input signal level condition. The input signal may be an audio signal. The switching amplifier may include a speaker coupled to receive output signal. The switching amplifier may include one or more additional pairs of transistor switches for alternately raising and lowering a voltage potential of the first terminal of the reactive element, each additional pair being selectively disabled by the low signal level detector upon detection of a corresponding low signal level condition. The transistor switches of the first pair may have substantially equal current carrying capacities which are substantially different from current carrying capacities of the transistor switches of the second pair. The low signal level detector may detect the low power condition by monitoring the input signal or by monitoring an error signal representative of a difference between the input signal and a reference level. The low power detector may include a window comparator. The window comparator may have a hysteretic transfer characteristic. The switching amplifier may include a feedback path from a terminal of the reactive element to the switch controller for limiting the
