PURPOSE: A method, a system, and a recording medium for transmitting a signal using zigbee are provided to apply zigbee which processes a signal in a digital method to a wireless microphone transceiving device. CONSTITUTION: A voice signal generated by A/D conversion, 0-QPSK modulation and RF transmission processes is transmitted. It is determined whether a response signal is received from a receiving side in response to the voice signal to change a channel. The voice signal is outputted to a speaker by performing one of RF receiving, 0-QPSK demodulation, D/A conversion and digital filtering. It is determined whether the voice signal is not received and an error occurs to change a channel.
