Abstract
PURPOSE:To suppress the mixture of control signal of both the tracks to the reproducing signal system, by detecting the control signal with the matrix and logic circuits, in the reproduction of left and right signal and control signal for two channel stereo. CONSTITUTION:The stereo voice and control signal recorded on a magnetic tape are respectively fed to preamplifiers 22, 32 via reproducing magnetic heads 21, 31, and they are respectively divided into two, and one is fed to a matrix circuit 40. In the matrix circuit 40, for example, the left channel signal fed to the 1st input terminal is divided into two. One is fed to the addition circuit 42 after it is reduced for the amplitude by (m) at the attenuator 41, and another is fed directly to the addition circuit 44. The right channel signal fed to the 2nd input terminal is similarly divided into two. One is fed to the addition circuit 44 after being phase-inverted at the phase inversion circuit 43, and another is directly fed to the addition circuit 42. With the constitution like this, the control signal is included only in the differential component signal, resulting that the mixing to the reproducing signal system can be suppressed.
