Switch.
When pressed to the IN position, power is applied to the PA1235X [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 PA1235X ON and OFF. Refer to "REMOTE MASTER ON/OFF CONTROL" terminals,
item #10.
NOTE: The PA1235X may also be powered ON/OFF with an external AC line switch into which the power
cord of the PA1235X is plugged (such as the switched AC outlet of a preamp, timer, etc. with a 15 Amp
rating). For this type of operation, leave the POWER switch depressed to the MANUAL ON position.
