PURPOSE:To attain recording of any mode without using a special circuit not a connecting code by outputting and switching an output signal of a detecting circuit of a sound multiplex signal and an output of a matrix circuit to prevent adverse effect on sound output state from a speaker. CONSTITUTION:Changeover switches 11, 12 are interlocked. When the switches are changed over to a, a' positions, a main sound signal M and a sub-sound signal S from sound detecting circuits 1, 2 are outputted to recording output terminals 9, 10. On the other hand, when switched to b, b' positions, an output signal of the matrix circuit 3, i.e., the same signal as the signal to speakers 7, 8 is outputted. Then, in stereo-recording a stereo broadcast, the switches are changed over to the positions b, b' and when the monaural recording is desired, the switches are switched to the positions a, a', and then the main sound signal from the output terminal 10 is outputted. |
