Note
(SAP) : The SAPOUT output signal is soft muted (approximately –7dB).
The signal is soft muted when NOISE = 1.
: Don’t care.

SAP or NOISE discrimination may be made during MONO or STEREO input when the noise is
inputted in the weak electric field.
Then microcomputer reads "NOISE" status from IC and decides whether SAP is outputted.
"NOISE" status rises earlier than "SAP" status when the amount of noise is increased to COMPIN.
