1. This design of this product contains special hardware and many circuits and components specially for safety
purposes. For continued protection, no changes should be made to the original design unless authorized in
writing by the manufacturer. Replacement parts must be identical to those used in the original circuits. Services
should be performed by qualified personnel only.
2. Alterations of the design or circuitry of the product should not be made. Any design alterations of the product
should not be made. Any design alterations or additions will void the manufacturer's warranty and will further
relieve the manufacture of responsibility for personal injury or property damage resulting therefrom.
3. Many electrical and mechanical parts in the products have special safety-related characteristics. These
characteristics are often not evident from visual inspection nor can the protection afforded by them necessarily
be obtained by using replacement components rated for higher voltage, wattage, etc.Replacement parts which
have these special safety characteristics are identified in the Parts List of Service Manual. Electrical
components having such features are identified by shading on the schematics and by ( ) on the Parts List in
the Service Manual. The use of a substitute replacement which does not have the same safety characteristics
as the recommended replacement parts shown in the Parts List of Service Manual may create shock, fire, or
other hazards.
4. The leads in the products are routed and dressed with ties, clamps, tubings, barriers and the like to be
separated from live parts, high temperature parts, moving parts and/or sharp edges for the prevention of
electric shock and fire hazard. When service is required, the original lead routing and dress should be
observed, and it should be confirmed that they have been returned to normal, after re-assembling.
5. Leakage current check (Electrical shock hazard testing)
After re-assembling the product, always perform an isolation check on the exposed metal parts of the product
(antenna terminals, knobs, metal cabinet, screw heads, headphone jack, control shafts, etc.) to be sure the
product is safe to operate without danger of electrical shock.
Do not use a line isolation transformer during this check.
Plug the AC line cord directly into the AC outlet. Using a "Leakage Current Tester", measure the leakage
current from each exposed metal parts of the cabinet, particularly any exposed metal part having a return
path to the chassis, to a known good earth ground.Any leakage current must not exceed 0.5mA AC (r.m.s.).
Alternate check method
Plug the AC line cord directly into the AC outlet. Use an AC voltmeter having, 1,000 ohms per volt or more
sensitivity in the following manner. Connect a 1,500 10W resistor paralleled by a 0.15 F AC-type capacitor
between an exposed metal part and a known good earth ground.
Measure the AC voltage across the resistor with the AC
voltmeter.
Move the resistor connection to each exposed metal part,
particularly any exposed metal part having a return path to
the chassis, and measure the AC voltage across the resistor.
Now, reverse the plug in the AC outlet and repeat each
measurement.Voltage measured any must not exceed 0.75 V
AC (r.m.s.).This corresponds to 0.5 mA AC (r.m.s.).
1.This equipment has been designed and manufactured to meet international safety standards.
2. It is the legal responsibility of the repairer to ensure that these safety standards are maintained.
3. Repairs must be made in accordance with the relevant safety standards.
4. It is essential that safety critical components are replaced by approved parts.
5. If mains voltage selector is provided, check setting for local voltage.

probe on
each exposed
metal part.

Burrs formed during molding may
be left over on some parts of the
chassis. Therefore, pay attention to
such burrs in the case of
preforming repair of this system.
In regard with component parts appearing on the silk-screen printed side (parts side) of the PWB diagrams, the
parts that are printed over with black such as the resistor ( ), diode ( ) and ICP ( ) or identified by the " "
mark nearby are critical for safety.
When replacing them, be sure to use the parts of the same type and rating as specified by the manufacturer.

2. Any unauthorised design alterations or additions will void the manufacturer's guarantee ; furthermore the
manufacturer cannot accept responsibility for personal injury or property damage resulting therefrom.
3. Essential safety critical components are identified by ( ) on the Parts List and by shading on the
schematics, and must never be replaced by parts other than those listed in the manual. Please note
however that many electrical and mechanical parts in the product have special safety related
characteristics. These characteristics are often not evident from visual inspection. Parts other than
specified by the manufacturer may not have the same safety characteristics as the recommended
replacement parts shown in the Parts List of the Service Manual and may create shock, fire, or
other hazards.

Caution: For continued protection against risk of
fire, replace only with same type 1A/125V for
F41, 2A/125V for F61, F62 and F42, 8A/ 125V for F21.
This symbol specifies type of fast operating fuse.
Precaution: Pour eviter risques de feux, remplacez
le fusible de surete de et F41 comme le meme type
que 1A/125V, et 2A/125V pour F61, F62 et F42,
8A/125V pour F21. Ce sont des fusibles suretes qui

Adjustment of idling current
Attention
This adjustment does not obtain a correct adjustment value immediately after the amplifier is
used (state that an internal temperature has risen).
Please adjust immediately after using the amplifier after turning off the power supply of the
amplifier and falling an internal temperature.
* It is not abnormal though the idling current might not become 0mA even if it is finished to turn variable
resistance (VR701, VR702, VR751, VR752, VR771, VR772, VR801) in the direction of counterclockwise.

<Adjustment method>
Prior to turning the power ON, fully turn the adjusting resistor (VR701, VR702, VR751, VR752, VR771,
VR772, VR801) counterclockwise direction and connect the DC voltmeter to the measuring terminal (B901-
B902, B903-B904, B905-B906, B907-B908, B909-B910, B911-B912, B913-B914).
Adjust the resistor so that the measured value becomes 2.0mV just after the power supply is turned on.
Adjust the resistor so that the measured value becomes 2.5mV more than 60 seconds after the power supply
is turned on.
After stability is 1.0-4.0mV.

Function
Calibration Active Signal Pin
"H" means the offset calibration cycle is in progress.Offset calibration starts
when RST goes "H". CAL goes "L" after 8704 LRCK cycles for DFS="L",
17408 LRCK cycles for DFS="H".
Reset Pin
When "L", Digital section is powered-down. Upon returning "H", an
offset calibration cycle is started. An offset calibration cycle should always
be initiated after power-up.
Serial Interface Mode Select Pin
MSB first, 2's compliment.
Left/Right Channel Select Clock Pin
LRCK goes "H" at SMODE2="L" and "L" at SMODE2="H" during reset
when SMODE1 "H".
Serial Data Clock Pin
Data is clocked out on the falling edge of SCLK.
Slave mode:
SCLK requires more than 48fs clock.
Master mode:
SCLK outputs a 128fs(DFS="L") or 64fs (DFS="H")clock.
SCLK stays "L" during reset.
Serial Data Output Pin
MSB first, 2's complement.SDATA stays "L" during reset.
Frame Synchronization Signal Pin
Slave mode:
When "H", the data bits are clocked out on SDATA. In I2S mode, FSYNC is
Don't care.
Master mode:
FSYNC outputs 2fs clock.FSYNC stays "L" during reset.
