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 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.)
Caution:
Pattern face side:
(SIDE B)
Parts face side:
(SIDE A)
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.
• SK2 REAR MAIN and REAR JACK boards are multi-layer
printed board. However, the patterns of intermediate lay-
ers have not been included in diagrams.
• Indication of transistor.

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.
• C : Panel designation.
Note:
The components identi-
fi ed by mark 0 or dotted
line with mark 0 are criti-
cal for safety.
Replace only with part
number specifi ed.
Note:
Les composants identifi és
par une marque 0 sont
critiques pour la sécurité.
Ne les remplacer que par
une pièce portant le nu-
méro spécifi é.
• A : B+ Line.
• Voltages and waveforms are dc with respect to ground
under wireless connection to the bar speaker (SA-Z9F/
ZF9).
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)
Note 1: Among mounted electrical parts on each board, only
parts that are described in the electrical parts list can
be replaced for repairing.
The parts that are not described in the electrical parts
list cannot be replaced with single for repairing.

Note 2: The SA-LZ9R (L-ch) and SA-RZ9R (R-ch) are the
same structure.
However, the model number label and the software
written on the RF modulator are different.
