trained to properly and safely repair complex products such as those covered by this manual.
Improperly performed repairs can adversely affect the safety and reliability of the product and may
void the warranty. If you are not qualified to perform the repair of this product properly and safely, you
should not risk trying to do so and refer the repair to a qualified service technician.
B
WARNING
This product contains lead in solder and certain electrical parts contain chemicals which are known to the state of California to
cause cancer, birth defects or other reproductive harm.
Health & Safety Code Section 25249.6 – Proposition 65
NOTICE
(FOR CANADIAN MODEL ONLY)
Fuse symbols
(fast operating fuse) and/or
(slow operating fuse) on PCB indicate that replacement
parts must be of identical designation.
REMARQUE
(POUR MODÈLE CANADIEN SEULEMENT)
C
Les symboles de fusible
(fusible de type rapide) et/ou
(fusible de type lent) sur CCI indiquent que
les pièces de remplacement doivent avoir la même désignation.
(FOR USA MODEL ONLY)
1. SAFETY PRECAUTIONS
The following check should be perfor med for the
continued protection of the customer and ser vice
technician.
LEAKAGE CURRENT CHECK
Measure leakage current to a known ear th ground
(water pipe, conduit, etc.) by connecting a leakage
current tester such as Simpson Model 229-2 or
equivalent between the ear th ground and all exposed
metal par ts of the appliance (input/output terminals,
screwheads, metal overlays, control shaft, etc.). Plug
the AC line cord of the appliance directly into a 120V
AC 60 Hz outlet and turn the AC power switch on. Any
current measured must not exceed 0.5 mA.
D
Leakage
current
tester
Device
under
test
E
Reading should
not be above
0.5 mA
Test all
exposed metal
surfaces
Also test with
plug reversed
(Using AC adapter
plug as required)
Earth
ground
ANY MEASUREMENTS NOT WITHIN THE
LIMITS OUTLINED ABOVE ARE INDICATIVE
OF A POTENTIAL SHOCK HAZARD AND
MUST BE CORRECTED BEFORE RETURNING THE APPLIANCE TO THE CUSTOMER.
2. PRODUCT SAFETY NOTICE
Many electrical and mechanical parts in the appliance
have special safety related character istics. These are
often not evident from visual inspection nor the
protection afforded by them necessarily can be obtained
by using replacement components rated for voltage,
wattage, etc. Replacement par ts which have these
special safety character istics are identified in this
Service Manual.
Electr ical components having such features are
identified by marking with a
on the schematics and
on the parts list in this Service Manual.
The use of a substitute replacement component which
does not have the same safety characteristics as the
PIONEER recommended replacement one, shown in the
parts list in this Service Manual, may create shock, fire,
or other hazards.
Product Safety is continuously under review and new
instructions are issued from time to time. For the latest
infor mation, always consult the current PIONEER
Service Manual. A subscription to, or additional copies
of, PIONEER Ser vice Manual may be obtained at a
nominal charge from PIONEER.

5. PCB PARTS LIST
NOTES:
Parts marked by "NSP" are generally unavailable because they are not in our Master Spare Parts List.
The mark found on some component parts indicates the importance of the safety factor of the part.
Therefore, when replacing, be sure to use parts of identical designation.
When ordering resistors, first convert resistance values into code form as shown in the following examples.
Ex.1 When there are 2 effective digits (any digit apart from 0), such as 560 ohm and 47k ohm (tolerance is shown by J=5%,
and K=10%).
560 Ω
56 x 10 1
RD1/4PU 5 6 1 J
561
47k Ω
RD1/4PU 4 7 3 J
47 x 10 3
473
0.5 Ω
RN2H R 5 0 K
R50
1Ω
RS1P 1 R 0 K
1R0
Ex.2 When there are 3 effective digits (such as in high precision metal film resistors).
5.62k Ω

Double Speed Sampling Mode Pin (Note 1)
"L" : Normal Speed, "H" : Double Speed
DAC4 Audio Serial Data Input Pin
Zero Input Detect Enable Pin
"L" : mode 7 (disable) at parallel mode,
zero detect mode is selectable by DZFM3-0 bits at serial mode
"H" : mode 0 (DZF1 is AND of all eight channels)
Output Buffer Power Supply Pin, 2.7V~5.5V
Digital Power Supply Pin, 4.5V~5.5V
Digital Ground Pin, 0V
Power-Down & Reset Pin
When "L", the AK4529 is powered-down and the control registers are reset to default
state. If the state of P/S or CAD0-1 changes, then the AK4529 must be reset by PDN.
Test Pin
This pin should be connected to DVSS.

Zero Input Detect 2 Pin
(Note 2)
When the input data of the group 1 follow total 8192 LRCK cycles with "0" input data,
this pin goes to "H".
Analog Input Overflow Detect Pin (Note 3)
This pin goes to "H" if the analog input of Lch or Rch is overflows.
Common Voltage Output Pin, AVDD/2
Large external capacitor around 2.2µF is used to reduce power-supply noise.
Positive Voltage Reference Input Pin, AVDD
Analog Power Supply Pin, 4.5V~5.5V
Analog Ground Pin, 0V
Zero Input Detect 1 Pin
(Note 2)
When the input data of the group 1 follow total 8192 LRCK cycles with "0" input data,
this pin goes to "H".
Master Clock Input Pin
Parallel/Serial Select Pin
"L" : Serial control mode, "H" :Parallel control mode
Audio Data Interface Format 0 Pin in parallel control mode
Chip Select Pin in 3-wire serial control mode
This pin should be connected toDVDD at I 2 C bus control mode
Audio Data Interface Format 1 Pin in parallel control mode
Control Data Clock Pin in serial control mode
I2C= "L" : CCLK (3-wire Serial), I2C = "H" : SCL (I 2 C Bus)
Loopback Mode 0 Pin in parallel control mode
Enables digital loop-back from ADC to 4 DACs.
Control Data Input Pin in serial control mode
I2C= "L" : CDTI (3-wire Serial), I2C = "H" : SDA (I 2 C Bus)
TDM I/F Format Mode Pin (Note 1)
"L" : Normal format, "H" :TDM format
A
B

D
Notes: 1. SDOS, SMUTE, DFS, and TDM pins are ORed with register data if P/S = "L".
2. The group 1 and 2 can be selected by DZFM3-0 bits if P/S = "L" and DZFE = "L".
3. This pin becomes OVF pin if OVFE bit is set to "1" at serial control mode.
4. All input pins should not be left floating.
