Note) The characteristics listed below are reference values based on the IC design and are not guaranteed.
It controls on/off of the mute function of
the headphone output.
The input
impedance: Equal
to or less than
about 170 k
HP amplifier
mute on/off
control terminal
DC : 2.0 V

It is the pin which controls power saving
by the headphone amplifier.
The entry

It is an output pin for the headphone
amplifier. The signal which was adjusted
in the volume in EVR can be output by
the low impedance.
The output
impedance
:
Equal
to or less than
about 1
Output terminal
for the HP
amplifier
DC : 2.20 V
AC :
4 dBV

It is the pin which controls power saving
by the speaker amplifier. At the time of
on in addition to the control in case of
automatic distinction function off, too,
power saving on by pin 50 have priority
over.
