る。Therefore, the sum of the sounds L1 emitted from the speakers 12,132> is always constant, and an electronic musical instrument whose sound image localization can be freely and reliably changed according to changes in the digital signal of the sound image localization information can be obtained. In addition, although vCA has various characteristics, it can be handled by setting the voltage dividing resistor of the control voltage generation circuit 2°, so it is not affected by the characteristics of VCA, and furthermore, the sum of the volume can be adjusted. For example, the volume can be set to be maximum when the sound image is localized to the center of the left and right speakers, rather than being kept constant, depending on how the resistors are set.

It is affected by the internal resistance (on-resistance) of 202 and is received by a high-impedance buffer, and the output U-change is made smooth by the resistor and capacitor. Therefore, it is preferable to include such a low-pass filter, since it is possible to prevent clicking noise caused by sudden changes in the VCA 24.250 control voltage.
