DIAGRAMS
For Schematic Diagrams.
Note:
•  All capacitors are in 
μF 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 
specifi ed.
•      f  : Internal component.
• 
 : Resistor.
•  C : Panel designation.
THIS  NOTE  IS  COMMON  FOR  PRINTED  WIRING  BOARDS  AND  SCHEMATIC DIAGRAMS.
(In addition to this, the necessary note is printed in each block.)
•  A : B+ Line.
•  Voltages and waveforms are dc with respect to ground in 
wireless connection to the bar speaker (SA-RT5).
  no mark : POWER ON
•  Voltages are taken with VOM (Input impedance 10 M
).
  Voltage variations may be noted due to normal production 
tolerances.
•  Waveforms are taken with a oscilloscope.
  Voltage variations may be noted due to normal production 
tolerances.
•  Circled numbers refer to waveforms.
• Signal path.
  F : 
AUDIO 
(ANALOG)
  J : 
AUDIO 
(DIGITAL)
For Printed Wiring Boards.
Note:
•  X : Parts extracted from the component side.
•  Y : Parts extracted from the conductor side.
•      f  : Internal component.
• 
 : Pattern from the side which enables seeing.
  (The other layers’ patterns are not indicated.)
Caution:
Pattern face 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.
Note: When the complete SUB MAIN board is replaced, re-
