Notes on chip component replacement

• Never reuse a disconnected chip component.

• Notice that the minus side of a tantalum capacitor may be
damaged by heat.

Unleaded solder

Boards requiring use of unleaded solder are printed with the lead
free mark (LF) indicating the solder contains no lead.
(Caution: Some printed circuit boards may not come printed with
the lead free mark due to their particular size.)

: LEAD FREE MARK

Unleaded solder has the following characteristics.

•Unleaded solder melts at a temperature about 40°C higher than
ordinary solder.
Ordinary soldering irons can be used but the iron tip has to be
applied to the solder joint for a slightly longer time.
Soldering irons using a temperature regulator should be set to
about 350°C.
Caution: The printed pattern (copper foil) may peel away if
the heated tip is applied for too long, so be careful!

• Strong viscosity
Unleaded solder is more viscous (sticky, less prone to flow)
than ordinary solder so use caution not to let solder bridges
occur such as on IC pins, etc.

• Usable with ordinary solder
It is best to use only unleaded solder but unleaded solder may
also be added to ordinary solder.

headphones.

2 ATT (attenuator) switch

Set this switch to Ò0 dBÓ if the volume is
too low for analog input. Normally, this
switch should be set to ÒÐ8 dB.Ó

3 LINE IN jacks

Connect the audio output jacks on an
audio or video component (sold
separately), such as a video cassette
player or TV, to these jacks.

4 DIGITAL IN jack

Connect a DVD device, digital satellite/
TV receiver, or other digital component
(sold separately) to this jack.

5 DIGITAL OUT jack

Connected components' digital signal
integrity retained when installed.

6 DC IN 9V jack

Connect the supplied AC power adaptor
to this jack. (Be sure to use the supplied
AC power adaptor. Using products with a
different plug polarity or other
characteristics can cause a malfunction.)

NOTE FOR PRINTED WIRING BOARDS AND SCHEMATIC 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 specified.

•%: indicates tolerance.

• f : internal component.

• C : panel designation.

• A : B+ Line.

• Power voltage is dc 9 V and fed with regulated dc power supply
from external power voltage jack.

•Voltages and waveforms are dc with respect to ground under no­signal conditions.

•Voltages are taken with a VOM (Input impedance 10 MΩ).
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 : ANALOG
J : DIGITAL

For printed wiring boards.
Note:

• X : parts extracted from the component side.

• f : internal component.

• : Pattern from the side which enables seeing.

Caution:
Pattern face side: Parts on the pattern face side seen from
(Side B) the pattern face are indicated.
Parts face side: Parts on the parts face side seen from
(Side A) the parts face are indicated.
