PURPOSE:To optimize the adjustment of separation both for the left and right channels, by independently adjusting the amount of superimposed stereo synthesis signal for left and right channels. CONSTITUTION:The left demodulation output L+DELTAR output to the collector of a transistor TR7 is subtracted with the left cross talk cancel signal K1X(L+R) output at TR13, and the left output signal without the component DELTAR is output at the output terminal 21 by adjusting the value of K1, i.e., the resistance value of the resistor 17. Similarly, the right side demodulation output R+DELTAL output at the collector of TR11 is subtracted from the right cross talk cancel signal K2X(L+R) output at the collector of TR14, and the right output signal without DELTAL is obtained at the output terminal 22 by adjusting the value of K2, i.e., the resistance value of the resistor 18. Thus, the stereo synthesis signal superimposed is independently adjusted at left and right channel, allowing to optimize the adjustment of separation for both left and right channels. |
