(3) Microphone mixing
In the microphone-input circuit, the input signal is passed through an op-amp buffer to prevent crosstalk between
FL and FR and then mixed with FL and FR. The level of the mixed signal changes in accordance with the variable
gain of the output gain amplifier (see the table below). A mute switch is incorporated to improve noise
characteristics when microphone mixing is not in use.
