AC Voltage Selection

115v / 230v AC Voltage Selector Switch

This switch is found on the underside of the chassis. Make sure the 115/230V switch is set for the correct AC line (mains) voltage before you plug in the JC 3’s AC power cord.

Note: The JC 3 could be seriously damaged if AC Voltage Selector switch is set incorrectly.

Prior to plugging your JC 3 into an AC power source, check the position of the 115v/230v switch on the JC 3’s chassis bottom and do not depend on the 115v or 230v markings on the carton.

The 115V setting is correct for North America where the JC 3 can operate safely with AC line voltages between 110-120v. Most other countries will require the switch to be set to 230V. With the 230V setting the JC 3 can operate safely with AC line voltages between 220V-240V.

Always turn off your JC 3 and disconnect its the AC cord before making or changing

any input, output or trigger wire connections. Inserting or removing an input or output cable while the JC 3 and your preamp and power amplifiers 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.
