[Feature] In a paper presented at the 110th AES Convention, Hebert and Thomas described the “phantom menace,” wherein phantom power faults can damage audio input circuitry. Their approach focused on the analysis of a “common-mode fault” occurring at the microphone preamplifier inputs, which was described as a “fault at both inputs, simultaneously.” However, this is not the only fault condition that can occur. New fault mechanisms are considered in this paper, and we show that commonly used protection schemes for popular integrated microphone preamplifiers do not always protect the preamplifiers as expected.
