We developed the prototype devices for the low delay digital radio microphone transmissions using OFDM and error correcting code. As a result of the laboratory experiment, the required CN ratio for BER=1x10^<-5> was 14.7dB which agree with the value calculated by the PC simulation. And the transmission delay was achieved 1ms or lower which is less than 1/3 that of conventional digital radio microphones transmitting compressed audio signals.
