43、This port monitors the midpoint voltage of the power amp power supply between +48V and -48V. If the voltage at the connection point of R801 and R802 exceeds DC 1.2V, Q903 or Q904 will turn on to change the signal from the PROT-2 (pin7) to L from H.Detection of an abnormality in the preamp power supp

If the +24VL of the relay power supply receives an electric current of over 80 mA, Q815 and Q901 will turn on to change the signal from the PORT-2 (pin7) to L from H.If any of the above three abnormalities is detected, the signal from the P_ON (pin15) terminal will be changed to L from H,

46、the power relay L852 will be turned off and the unit will be shut down. Then, the STANDBY indicator flickers and indicates that an abnormality has occurred. This protection operation is intended for a breakdown of the AMP circuit or the power supply circuit and immediately shut s off the power in or
