SWITCH 

When pressed to the IN position, power is applied to the PA635X [provided the rear panel 

master AC LINE ON/OFF Switch, item #13, is placed in the ON (I) position].  This is the MANUAL ON position.  
When pressed again, it releases to the OUT position (MANUAL OFF), turning the unit OFF. 

 
 

In addition, this switch must be left in the MANUAL OFF (OUT) position to permit an external DC Control Voltage 
to power the PA635X ON and OFF. Refer to "REMOTE MASTER ON/OFF CONTROL" terminals, item #10. 

 
 

NOTE:  The PA635X may also be powered ON/OFF with an external AC line switch into which the power cord of 
the PA635X is plugged (such as the switched AC outlet of a preamp, timer, etc. with a 5A minimum rating).  For 
this type of operation, leave the POWER switch depressed to the MANUAL ON position.
