回路。In a tape recorder that mixes and superimposes a signal from a microphone on the playback signal of a recording recorded on a tape, a buffer amplifier that takes the input from the tip contact of the microphone jack as an input and supplies the output to the tape playback circuit through a high resistance. A low resistance is connected between the input terminal of the amplifier and ground, and the contact piece in the microphone jack connected to the output side of the amplifier is configured to be separated from the tip contact piece in the microphone jack when a microphone plug is inserted. A mixing circuit for microphones characterized by:
