DIAGRAM
(This schematic diagram may be modified at any time with the development of new technology.)
Notes:
esi : Power switch in “on” position.
(i off, = on)
es2 : Voltage selector switch in “240 V” position.
(For [EK], [XL], [XA], [PA] and [PE] areas.)
©S101,S102: Speaker selector switch in “Main” position.
$101: Remote, $102: Main
eS$201 : Stereo/monaural selector switch in “stereo” position.
Indicated voltage values are the standard values for the unit measured by the DC electronic circuit tester (high-impedance) with
the
chassis
taken
as
standard.
Therefore,
there
may
exist
some
errors
in
the
voltage
values,
depending
on
the
internal
impedance of the DC circuit tester.
@
Phono signal line (Lch).
= |_| Positive voltage line.
== Negative voltage line.
©|mportant safety notice:
Components
identified
by

have
special
characteristics
important
for
safety.

replacing
any
of
these
