Note) The characteristics listed below are reference values based on the IC design and are not guaranteed.
It is the voice input pins of the speaker
amplifier. To make offset voltage in
power saving on/off changing by the
speaker amplifier little, it combines
capacity.
( It makes POP noise small ).
Pin 44: R-channel speaker entry
Pin 45: L-channel speaker entry

It is the standard voltage pin to fix the
DC bias of the speaker output. It
connects a condenser to remove a ripple.
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

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 47, pin 50 has
priority over.
The range under
about 1.5 V.
