Abstract
A circuit and method of switching an output of a single preamplifier to or from multiple amplifier output stages. The preamplifier output is switched between multiple audio amplifier output stages without degrading the performance of the output signal. A switching circuit selectively couples the preamplifier output to an amplifier output stage and also couples a feedback loop between the selected amplifier output stage and the preamplifier stage.
