Abstract
Embodiments relate to a microphone that functions as either a digital wireless microphone or a wired passive microphone. The microphone may comprise: a microphone transducer; an analog to digital converter (ADC) coupled to the microphone transducer to convert an analog audio signal from the microphone transducer to a digital audio signal; an antenna coupled to the ADC; and an analog connector coupled to the microphone transducer. In a wireless mode, the antenna transmits the digital audio signal to a digital receiver. Alternatively, in a wired mode, a cable that is coupled to the analog connector transmits the analog audio signal without requiring any power.
