PROTECTOR OPERATION 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 removed.
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 removed.
4. Verify that the protector is released and LED901 illuminates green
when the power is turned off and then on again.
