Abstract
A microphone adapter connects to and receives analog audio input from a microphone and an external music source, such as a smart phone. The microphone audio input signal and external music audio input signal are converted to digital signals and multiplexed into a digital wireless signal that may be transmitted directly to multiple speakers. The digital wireless signals are uncompressed, high definition digital audio signals transmitted in the 2.4 GHz band with a range of several hundred feet. The microphone adapter enables user to easily establish a pop-up public address system without the need for speaker cables, sound boards, mixers, and the like.
