PROTECTOR OPERA TION CHECK
Thermal Protect
1. Short across TH901 with the power on.
2. Verify that the protector is operated and LED901 illuminates
red.
3. Verify that the protector is released and LED901 illuminates green
when the short is removed.
4. Likewise, perform items 1 to 3 for TH902 and TH903.
Over Current Protect
1. Short between the positive and negative sides of the speaker
output terminal CN903 and CN904 (1/2) with the power on.
(Perform this shorting for each channel on FRONT and REAR.)
2. Verify that the protector is operated and LED901 illuminates
red.
3. Verify that the protector is not released and LED901 remains
red even when the short is remov e d.
4. Verify that the protector is released and LED901 illuminates green
when the power is turned off and then on again.
Offset Protect
1. Short between the +12V terminal of CN904 (2/2) and the BTL+
or BTL– of the speaker output terminal CN903 and CN904 (1/
2).
(Short between +12V terminal and BTL+ and between +12V
terminal and BTL–.)
2. Verify that the protector is operated and LED901 illuminates
red.
3. Verify that the protector is not released and LED901 remains
red even when the short is remov e d.
4. Verify that the protector is released and LED901 illuminates green
when the power is turned off and then on again.

printed in each block.)
for schematic diagram:
• 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/
specified.
Note:
The components identified by mark 0 or dotted
line with mark 0 are criti-
cal for safety.
Replace only with part
number specified.
• A : B+ Line.
• B : B– Line.
• Power voltage is dc 14.4V and fed with regulated dc power
supply from +12V and REM 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 production tolerances.
•Waveforms are taken with a oscilloscope.
Voltage variations may be noted due to normal production tolerances.
• Circled numbers refer to waveforms.
