によるステレオ信号の音量調整回路。 One of the stereo signals is applied as an input to a first terminal of a three-terminal volume and taken out as an output from the same terminal, and the other of the stereo signals is applied as an input to a second terminal of the same volume and output from the same terminal. Take it out, and follow step 3 above.
A movable element is connected to the third terminal for common grounding of the terminal volume, and by moving this movable element, the resistance value between the first terminal and the third terminal and the resistance value between the second terminal and the second terminal are changed. The stereo signal with a three-terminal volume is characterized in that the resistance value between the third terminal and the third terminal is changed by the same amount at the same time, and both outputs of the stereo signal are changed by the same amount at the same time. Volume adjustment circuit.
