• IC Block Diagram
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 diagram:
• All capacitors are in µF unless otherwise noted. pF: µµF
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
specified.
• % : indicates tolerance.
•
f
: internal component.
•
C
: panel designation.
•
A
: B+ Line.
•
B
: B– Line.
• Power voltage is dc 14.4V and fed with regulated dc power
supply from +12 V and REMOTE terminals.
• Voltages are taken with a VOM (Input impedance 10 M
Ω
).
Voltage variations may be noted due to normal produc-
tion tolerances.
• Waveforms are taken with a oscilloscope.
Voltage variations may be noted due to normal produc-
tion tolerances.
• Circled numbers refer to waveforms.
• Signal path.
F
: AUDIO
for printed wiring boards:
•
X
: parts extracted from the component side.
• Y : parts extracted from the conductor side.
•
z
: Through hole.
• : Pattern from the side which enables seeing.
(The other layer’s patterns are not indicated.)
Caution:
Pattern face side: Parts on the pattern face side seen from the
(Side B)
pattern face are indicated.
Parts face side: Parts on the parts face side seen from the
(Side A)
parts face are indicated.
