... M61520FP Functional description (1) Input selector, input attenuator The IC incorporates a selector for either of two six-input channels and a mute switch. An input level for the selected input is chosen from among -4.4, -8, -9.4, -11.6, -13, and -16.6 dB. 60k 1 60k 2 60k 3 60k 4 60k 5 60k 6 (2) REC block The REC signal is mixed with the MIC signal and then output ...

... M61520FP (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 ...
