Service PM8004 / K1SG/U1B PM-KI-PEARL-LITE / N1SG/N1B Manual N2SG/N2B Integrated Amplifier • For purposes of improvement, specifications and design are subject to change without notice. • Please use this service manual with referring to the operating instructions without fail. • Some illustrations using in this service manual are slightly different from the actual set.
Page 2 MARANTZ Parts for your equipment are generally available to our National Marantz Subsidiary or Agent. ORDERING PARTS : Parts can be ordered either by mail or by Fax.. In both cases, the correct part number has to be specified.
Page 3: Safety Precautions
SAFETY PRECAUTIONS The following check should be performed for the continued protection of the customer and service technician. LEAKAGE CURRENT CHECK Before returning the unit to the customer, make sure you make either (1) a leakage current check or (2) a line to chassis resistance check.
Page 4: Note For Schematic Diagram
NOTE FOR SCHEMATIC DIAGRAM WARNING: Parts marked with this symbol z have critical characteristics. Use ONLY replacement parts recommended by the manufacture CAUTION: Before returning the unit to the customer, make sure you make either (1) a leakage current check or (2) a line to chassis resistance check. If the leakage current exceeds 0.5 milliamps, or if the resistance from chassis to either side of the power cord is less than 460 kohms, the unit is defective.

Page 15: Protection Mode
PROTECTION MODE Explanation of microprocessor (U101) [PROT-1 (pin6) and PROT-2 (pin7)]. 1. The PROT-1 (pin6) is the port to detect the following abnormalities of the Power AMP (1) D etection of an abnormality in the DC offset voltage from the Speaker Output terminal. If the voltage from the Speaker Output terminal exceeds approximately 1.2V (DC), Q955 or Q956 will turn on and the signal from the PROT-1 terminal will change to "L" from "H". (2) D etection of an abnormal current from the power transistors (Q713 ~ Q716). If an electric current of over 7A flows in Q713 or Q715, Q951, Q953 and Q957 turn on, and the signal from the PROT-1 terminal will change to "L" from "H". If an electric current of over 7A flows in Q714 or Q716, Q952, Q954 and Q957 turn on, and the signal from the PROT-1 terminal will change to "L" from "H". (3) Detection of an abnormal temperature of the Heat Sink. If the temperature of the Heat Sink exceeds approximately +110 degrees C, the posistor (R969) will turn on Q958 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 circuit will be activated, the signal from the SPK_OUT (pin10) changing to "H" from "L" and the speaker relays L751, L752 and L753 immediately turned off. What this protection operation results in after this depends on how long the signal from the PROT-1 has to remain "L".
