Abstract

PURPOSE:To use two wireless microphones at the same time and mixing sounds for reproduction by providing an FM reception demodulating section to wireless microphones and applying FM modulation and transmitting at an FM modulation transmitting section, a signal mixing the signal demodulated at the FM reception demodulation section and a signal caught by a microphone unit. CONSTITUTION:An FM radio wave transmitted from another wireless microphone is caught by a reception antenna 5 and demodulated by an FM reception demodulation section 6. The demodulated signal and a signal caught by the microphone unit 1 and amplified by an amplifier section 2 are mixed by a mixing section 7. The mixed signal is converted into an FM radio wave by an FM modulation transmission section 3 and transmitted from a transmission antenna 4.

However, with the above conventional configuration, when two wireless microphones are used at the same time and you want to mix both sounds (for example, in the case of chorus), FMi waves, as is generally well known, are two radio waves of the same frequency. If there is a strong signal, the stronger signal will suppress the weaker signal, so only the sound from the wireless microphone with the stronger signal will be played, and the sound from the two wireless microphones will be mixed. The problem was that it could not be played back.
