5. ELECTRICAL PARTS LIST
NOTES:
A
B
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
562 x 10 1

7.3.4 AMPLIFIER SYSTEM PROTECTION OPERATION SPECIFICATION
1. DC-abnormality detection
DC detection is only enabled 2 seconds after power-on.
If there is a fault in the power amplifier or a high-level signal lower than 5 Hz is input,
the DC_DET port becomes “L”.
If the “L” is detected, the microprocessor will perform as following flow chart.
A
In the case of simultaneous detection with the overload protection circuit,
DC-abnormality detection is performed preferentially to overload detection.
When a DC abnormality is detected, A.MUTE* is turned
on, speaker relay is turned off, then
"AMP_ERR" flashes on the display.
*A.MUTE : Audio mute command
↓
B
The abnormality continues for 3 seconds.
↓ Continues.
↓ Recovery
The program restarts.
The power is shut off.
↓
Power key not effective and POWER LED blinks.
However, when the following keys are pushed so that the key input of a line and the service can
be carried out, power can be on. (If don't push these key, need to wait 1 min then power can be on again.)
1 TESTMODE ON (A55F+A55F)
2 When power off, push FRONT ENTER key + ADVANCED SURROUND key continuously 2sec.
(2: When a DC abnormality is detected and the power is shut off.)
C
2. Overload detection
If the speaker terminals are short-circuited or low-load driving is detected, the OL_DET port becomes “L”.
If the “L” is detected, the microprocessor will perform as following flow chart.
When an overload is detected, A.MUTE* is turned on,
speaker relay is turned off, then
"OVERLOAD" flashes on the display.
D
↓
↓ Continues.
↓ Recovery
The power is shut off even if the
unit recovers.

3. Board detection
If the board connection from Main Ass’y to Amp&Primary Ass’y is interrupted,
the BOARD_DET port becomes “H”.
If the “H” is detected, the microprocessor will perform as following flow chart.
A
In the case of simultaneous detection with the overload protection circuit,
Board detection is performed preferentially to DC-abnormality detection and Overload detection.
When an boad error is detected, A.MUTE* is turned on,
speaker relay is turned off, then
"BOAD ERR" flashes on the display.
↓
B
↓ Continues.
↓ Recovery
The power is shut off even if the
unit recovers.
4. Fan stop detection operation flow in the DC abnormality detection
If the fan is forcibly stopped, the 'DC PROT' port becomes "L". Then an abnormality of fan is detected.
C
When an abnormality of fan is detected,
A.MUTE* is turned on, speaker relay is turned off,
the "AMP_ERR" flashes on the display.
*A.MUTE : Audio mute command
↓
↓ Continues.
↓ Recovery
The program restarts.
D
↓
The power key is disabled.
However, when the following keys are pushed so that the key input of a line and the service can be carried out,
power can be on.
1 TESTMODE ON (A55F+A55F)
2 When power off, push FRONT ENTER key + ADVANCED SURROUND key continuously 2sec.
(Effective, only when power-off is carried out by DC detection)

7.3.5 AMPLIFIER FAILURE DIAGNOSIS FLOW CHART
Amplifier failure diagnosis flow chart
A
When DC detection is activated ("AMP_ERR" flashes on the display), failure (damage) of the power amplifier
section is considered.
As DC detection and fan stop protection circuits commonly use same abnormality detection port in
microprocessor, please make sure that the operation of fan motor is in normal condition before proceeding to
the troubleshooting of amplifier.
Caution:
When release the lock state of power key before repair, please be careful because there is the possibility that
more damages will occur when turns on the power once again!
B
• According to a symptom, perform the following confirmation beforehand.
1) Is the operation of fan motor in normal condition?
2) Are there any Fuses and IC protectors open?
3) After turn on the power, confirm that the supply voltage of the point that can be measured is appropriate.
4) Whether the voltage of pin3 of IC601 or IC602 is equal to (VL-0.7V). If not (eg, equal to VH), then change
the corresponding power pack IC601 or IC602.
C
5) Furthermore, check the output DC voltage of each channel of power pack IC601 and IC602 to limit the
failure channel and identify the defect power pack.
• After identify the failure channel, check that each part is not damaged (resistor, diode... etc. value / open /
short)
