发明名称 Radio microphone set with digital transmission and analog signal correction
摘要 A radio microphone set with digital transmission and analog signal correction (1), comprising a radio-frequency transmitter (2) and a radio-frequency receiver (3), provided respectively with an encoding unit comprising an analog/digital signal converter (7), driven by an audio signal detector (2a) and with a signal decoding unit driving sound diffusion elements (4); the transmitter (2) having a first line and a second line that lead to respective transmission components at different frequencies for the digital (9a) and analog (11a) signals; the receiver (3) having respective lines originating from digital and analog signal receiving components with incorrect signal detection device (19), a digital/analog signal converter (15) and a switch (20) adapted to send to elements (4) signal from converter (15), replacing incorrect signal (16a) with analog signal (18a). <IMAGE>
