[Noise detecting circuit reference]
This pin must be grounded through C8
(22
μ
F).
[LOG amp.(1)input(from MIC amp. out-
put)]
This pin connects through C9(0.1
μ
F)and
R15(5.1 k
)to the MIC amp. output.
[LOG amp.(2)input(from hands-free
control output)]
This pin connects through C10(0.1
μ
F)and
R16(5.1 k
)to the HF control output.
[LOG
preamp. output)]
This pin connects through C11(0.1
μ
F)and
R17(5.1 k
)to the receiver preamp. out-
put.
amp.(4)input(from
receiver
[LOG amp.(3)input(from loudspeaker
amp. output)]
This pin connects through C12(0.1
μ
F)and
R18(5.1 k
)to the loudspeaker amp. out-
put.
[LOG amp.(1)output]
Outputs amplified MIC amp. output.
Grounded through C13(2.2
μ
F). The
attack recovery time of the attenuator
changes with the capacitance of C13.
