36、 PROTECTION MODEExplanation of microprocessor (QU01) PROT-1 (pin54) and PROT-2 (pin53).A The PROT-1(pin54) is the port to detect the following abnormalities of the Power AMP1. Detection of an abnormality in the DC offset voltage from the Speaker Output terminal.If the voltage from the Speaker Output

37、 terminal exceeds approximately 1.2V (DC), Q954 or Q955 will turn on and the signal from the PROT-1 terminal will change to L from H.2. Detection of an abnormal current from the power transistors (Q622, Q623, Q722, Q723).If an electric current of over 10A flows in Q622 or Q623, Q624, Q625 and Q957 t

38、urn on, and the signal from the PORT-1 terminal will change to L from H.If an electric current of over 10A flows in Q722 or Q723, Q724, Q725 and Q957 turn on, and the signal from the PORT-1 terminal will change to L from H.3. Detection of an abnormal temperature of the Heat Sink.If the temperature o

39、f the Heat Sink exceeds approximately +110 degrees C, the posistor (R672 and R772) will turn on Q956 and the signal from the PROT-1 terminal will change to L from H.If any of the above three abnormalities is detected, the signal from the PROT-1 terminal will change to L from H, and the protection ci

40、rcuit will be activated, the signal from the SPK_OUT (pin40) changing to L from H and the speaker relays L901 immediately turned off.What this protection operation results in after this dependson how long the signal from the PROT-1 has to remain L. If the PROT-1 (pin54) recovers to “H” within as sho

41、rt a period of time as one second or less.The message “PROTECT” flashes on the display, thereby indicates that the protection circuit has come into operation and automatically turns down the volume.The protection circuit is deactivated after approximately 8 seconds, so that readjusting the volume wi

42、ll allow normal use of the unit again. This protection operation is intended for the situation wherein the user has misused the unit temporarily and automatically resets the unit while the amp circuit is functioning properly. If the PROT-1 (pin54) remains L for more than one second.The amp will be p

43、owered off by the POW-1 (pin25) changing to L from H and Power relay L852 turned off.Then, the OPERATION indicator flickers, thereby indicating that an error has occurred. This protection operation is intended for a failure in the amp circuit and immediately turns the power off to avoid the risk of

44、any damage. Depending on how the user is handling the unit, this operation may be performed no matter if the amp is functioning properly.5.

47、E点滅。電源再投入PROTECTION動作解除場合、 回路故障考。7To check if the amp is in order, switch off the unit and switch it on again one minute later. This action will deactivate the protection operation. If the PROT-1 (pin54) remains “L”, which constitutes an abnormality, the unit shuts down approximately 2 seconds later

48、 and the OPERATION indicator starts flickering.If the protection operation will not be deactivated after the power is turned on again, the amp circuit may be broken.B The PROT-2 (pin53) is the port to detect abnormalities of the power supply circuit 1. Detection of an abnormality in the power amp po

If the voltage at the connection point of R829 and R830 exceeds DC 1.2V, Q823 or Q824 will turn on to change the signal from the PROT-2 (pin53) to L from H.2. Detection of an abnormality i

If the voltage at the connection point of R823 and R824 exceeds DC 1.2V, Q821 or Q822 will turn on to change the signal from the PROT-2 (pin53) to L from H 3.
