AC Power
Be sure the ShowBox is plugged into an outlet that is able to supply the correct voltage. It will continue to operate at lower
voltages, but will not reach full power. Be sure the electrical service can supply enough amperage for all the components
connected to it.
We recommend that a stiff (robust) supply of AC power be used because the amplifiers place high current demands
on the AC line. The more power that is available on the line, the louder the speaker will play and the more peak output
power will be available for a cleaner, punchier bass. A suspected problem of “poor bass performance” is often caused
by a weak AC supply to the amplifiers.
Never remove the ground pin on the power cord or any other component of the ShowBox. This is very dangerous.
Care and Maintenance
Your ShowBox will provide many years of reliable service if you follow these guidelines:
• Avoid exposing it to moisture. If it is set up outdoors, be sure it is under cover if rain is expected.
• Avoid exposure to extreme cold (below freezing temperatures). If you must operate in a cold environment, warm up
the voice coils slowly by sending a low-level signal through them for about 15 minutes prior to high-power operation.
• Use a dry cloth to clean the cabinet. Only do this when the power is turned off. Avoid getting moisture into any
of the openings of the cabinet, particularly where the drivers are located.
