2. DIAGRAMS
THIS NOTE IS COMMON FOR PRINTED WIRING BOARDS AND SCHEMATIC DIAGRAMS.
(In addition to this, the necessary note is printed in each block.)
For Schematic Diagrams.
Note:
• All capacitors are in
μ
F unless otherwise noted. (p: pF) 50
WV or less are not indicated except for electrolytics and
tantalums.
• All resistors are in
Ω
and 1/4 W or less unless otherwise
speci
fi
ed.
•
C
: Panel designation.
•
A
: B+ Line.
•
B
: B– Line.
• Voltages are dc with respect to ground under no-signal
conditions and state of connecting to two speakers (SS-
HW5).
no mark : POWER ON (Headphone is not connected)
( ) : POWER ON (Headphone is connected)
*
: Impossible to measure
• Voltages are taken with VOM (Input impedance 10 M
).
Voltage variations may be noted due to normal production
tolerances.
• Signal path.

:
AUDIO
(ANALOG)
J
:
AUDIO
(DIGITAL)
E
:

:
BLUETOOTH
For Printed Wiring Boards.
Note:
•
X
: Parts extracted from the component side.
•
Y
: Parts extracted from the conductor side.
•
: Pattern from the side which enables seeing.
(The other layers’ patterns are not indicated.)
• Indication of transistor.

Caution:
Pattern face side:
(Conductor Side)
Parts face side:
(Component Side)
Parts on the pattern face side seen
from the pattern face are indicated.
Parts on the parts face side seen from
the parts face are indicated.
• MAIN board is multi-layer printed board. However, the
patterns of intermediate layers have not been included in
diagrams.
Note:
When the complete MAIN board is replaced, refer to
“WRITING OPERATION OF SERIAL NUMBER AF-
TER REPLACING THE MAIN BOARD” on page 6
