ABSTRACT:
An apparatus includes first and second amplifiers, each having an input coupled to an audio signal input and an output coupled to an audio signal output. The second amplifier also has a feedback path from its output to its input. A first switch can be operated to selectively couple and uncouple the audio signal input and the input to the first amplifier to and from a first node. A second switch can be operated to selectively couple and uncouple the input of the second amplifier to and from a second node. A third switch can be operated to selectively couple and uncouple the first node to and from ground.
