LC181 based three-way audio control and voltage-controlled lights

LCl81 audio control circuit voltage-controlled three-way lights
the circuit components are used: LC181 9013 9014
circuit as shown. It includes the audio pickup and amplifier circuit, light control circuits and AC step-down and rectification circuit. BM-type electret condenser microphone for the CRZ2, it can check the sound picked up signals are converted to electrical signals, amplified by the VT1 added to the emitter follower VT2, and add to the LC181 UIN rectifier amplifier input terminal 5 feet its internal voltage-controlled voltage-controlled oscillator modulation.
