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:
Note:
• 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 / W or less unless otherwise
4
specified.
• % : indicates tolerance.
• 2 : nonflammable resistor.
• U : B+ Line.
• V : B– Line.
• Power voltage is dc 14.4V and fed with regulated dc power
supply from +12V and REMOTE terminals.
• Voltage is dc with respect to ground under no-signal
condition.
• Voltages are taken with a VOM (Input impedance 10 MΩ).
Voltage variations may be noted due to normal produc-
tion tolerances.
• Signal path.

: AUDIO
for printed wiring boards:
Note:
• X : parts extracted from the component side.
• b : Pattern from the side which enables seeing.
(The other layer's patterns are not indicated.)
