3、re the amplifier is plugged in, be sure its rated voltage corresponds to the voltage of the AC power source to be used.Incorrect voltage could cause damage to the amplifier when the AC power cord is plugged in. Do not exceed rated voltage by more than 10%: operation below 90% of rated voltage will c

4、ause poor performance or may shut the unit off. Leakage/Resistance Check Before returning the unit to the customer, perform a leakage or resistance test as follows: Leakage Current. Connect the unit to its rated power source. Using an ammeter, measure the current between the neutral side of the AC s

5、upply and chassis ground of the unit under test. if leakage current exceeds 0.5mA, the unit is defective. Reverse the polarity of the AC supply and repeat. Resistance. Measure the resistance from either side of the line cord to chassis ground. If it is less than 500k ohms, the unit is defective. WAR
