Abstract

PURPOSE:To avoid generation of the crosstalk signal component without lowering the degree of separation of both main and secondary aural signals or both left and right signals, by generating the double multiple signal and the stereo multiple signal through operation of the change-over switch or the like. CONSTITUTION:The 1st frequency modulator U1 connected with the main signal or the L input is connected to fixed contact (a) of switch S1 out of the 1st and 2nd change-over switches S1 and S2 which are interlocking each other for the double multiple switching purpose; while fixed frequency oscillator U2 of oscillation frequency f1 is connected to fixed contact (b) each. At the same time, the 2nd frequency modulation oscillator U2 connected with the secondary signal or the R input is connected to fixed contact (a') of switch S2; while the output of frequency mixer U5 which generates the output of frequency f1-f5 is connected fixed contact (b') each. And then the 2nd frequency mixer U9 connected to the output of oscillator U1 is connected to switch contact (c) of switch S1; while the 1st frequency mixer U8 connected to the output of oscillator U2 is connected to switch contact (c') of switch S2 each. Then switches S1 and S2 are switched to the stereo side and the double multiple side each to deliver the stereo multiple signal and the double multiple signal each via 3rd frequency mixer U13.
