An interface is provided between a transducer and audio processing circuitry. The interface has a switching device coupled to the transducer. The interface also has a first signal path that is selectively coupled to transducer via the switching device and includes a first output, the first signal path being configured to selectively receive input signals from the transducer, and form a first output signal at the first output by amplifying the input signals to provide a first gain. The first output is coupled to the audio processing circuitry. A second signal path is provided that is selectively coupled to the transducer via the switching device and includes a second output. The second gain is selected to be substantially larger than the first gain. The switching device is configured to switch the input signal between the first signal path and the second signal path.
