AC Voltage Selection 

 
 

115

 

V / 230

 

V AC Voltage Selector Switch 

 

This switch is found on the underside of the chassis.

 

Make sure the 115

 

V/230

  

V switch is set for 

the correct AC line (mains) voltage 

before

 you plug in the JC 3 Jr.’s AC power cord. 

 
 
 

 

 
 
Note: The JC 3 Jr. could be seriously damaged if the AC Voltage Selector switch is in the 
wrong position for your voltage! 
 
Prior to plugging your JC 3 Jr. into an AC power source, check the position of the 
115v/230v switch on the JC 3 Jr.’s chassis bottom and do not depend on the 115

 

V or 230

 

markings on the carton

.

 

 
 

The 115

 

V setting is correct for North America where the JC 3 Jr. can operate safely with AC line 

voltages between 110

 

V-120

 

V. Most other countries will require the switch to be set to 230

 

V. With 

the 230

 

V setting the JC 3 Jr. can operate safely with AC line voltages between 220

 

V-240

 

V.   

 
 
Always turn off your JC 3 Jr. and disconnect its AC cord before making or changing the input, 
audio output or trigger wire connections. Inserting or removing an input or output cable while the 
JC 3 Jr. and your line stage preamp and power amplifier are turned on can result in a blast of 
sound that can damage your loudspeakers. Make sure there is no strain or tension on any cables 
that could cause them to pull loose.
