3. Connections of speaker wires should be made before
connecting the AC power supply cords.
Mi PROTECTION CIRCUITRY
The protection circuitry may have operated if either of If this occurs, follow the procedure outlines below:
the following conditions is noticed: 1. Turn off the power.
© No sound is heard when the power is turned on. 2. Determine the cause of the problem and Correct it.
© Sound stops during a performance. 3. Turn on the power once again after one minute.
The function of this circuitry is to prevent circuitry Note:
damage if, for example, the positive and negative
Speaker connection wires are ‘‘shorted”, or if speaker
systems with an impedance less than the indicated
rated impedance of the amplifier are used.
When the protection circuitry functions, the unit will
not operate unless the power is first turned off and
then on again.
Mi BEFORE REPAIR AND ADJUSTMENT
1. Turn off the power, Discharge both power supply 2. After completion of repair, slowly apply the primary
