5 6 7 8 5.3 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.
1 2 3 4 3. XPROTECT detection XPROTECT is started to be monitored 200msec after power on. XPROTECT port is checked every 20msec. If Low level (ERROR) is recognized during consecutive 9 times, micon judge it as XPROTECT ERROR. A It processes more preferentially than DC abnormal detection and overload detection. POWER ON ↓ When 200 msec passed after power on, the XPROTECT detection starts. Don't detect it during power off.
