Changing Voltage
Your PRX500 series speaker will typically be set at the factory to accommodate the power mains voltage in your
area. Before you set up your PRX500 series speaker for the first time it is a good idea to verify that the setting
of the selector is appropriate for the power in your area. In the event that you do need to change the voltage:
• Make sure that the speaker is powered off and the AC is disconnected from the speaker.
• Directly above the male IEC connector on the speaker is a voltage selector. Just slide the
switch to the appropriate setting.
• Set the voltage selector switch to the 115V for (100-120V~) or 230V for (220-240V~) range setting
as required for your area.
• After having reconfirmed that the correct voltage is selected, reconnect the AC (IEC connector)
and power the unit up.
DO NOT UNDER ANY CIRCUMSTANCES OPERATE THE UNIT WITH THE WRONG VOLTAGE SELECTED.
DOING SO MAY RESULT IN SERIOUS DAMAGE TO YOUR SPEAKER SYSTEM WHICH WILL NOT BE
COVERED BY WARRANTY.

AC Power Requirements
Standard PRX500 series speaker systems are equipped with a multi-channel Crown Class-D power amplifier
and loudspeaker specific DSP electronics and require appropriate AC power. Before plugging a PRX500
speaker into an outlet ensure that it is able to provide the appropriate AC power as set on the speaker.
A robust AC supply is necessary for maximum performance. If the supply is too weak the bass performance may
be affected and if it sags (drops) too much the system may self-mute to protect itself. As soon as the appropriate
AC supply is restored it will continue to operate. Plugging multiple systems into the same outlet and long
extension cord runs may affect the AC supply to the systems.
CAUTION
In compliance with safety agency criteria and proper system operation, it is critical that the system installer
observe all electrical safety practices at all times and provide proper earth grounding for all AC Power
connections.
Powering Up
The main power switch is located on the input panel on the back of the enclosure. Always ensure that the
speaker system is the last thing you power up, and the first thing to turn off when operating your complete PA
system. If speaker systems are daisy chained together always turn off the last system in the chain first. Power
“on” is indicated by the illumination of the logo on the front of the enclosure.
