Electrical Installation
9
Power IN
The system requires one (1) 20 amp, 120 VAC circuit; 2W + GND. A power cord is located
inside the control enclosure.
Turn off power to the amplifier when not in use. The amplifier should be turned off after
each game/event in order to extend the life of the system and deter unauthorized use.
To turn off the amplifier, press and hold the front power button until the screen goes
black and the power button changes from blue (or flashing red) to red. If the power
button is flashing red, the amplifier is off, but the processing and screen remain on. There
is also a rocker switch next to the power connection on the back of the amplifier. This
switch is the safest method to power off the amplifier if the system will not be used for an
extended period of time and to protect from surge conditions.
Grounding
All components of an audio system – including but not limited to control equipment,
and connected peripheral equipment – must be electrically grounded. Only qualified
individuals may perform electrical work, including verification of ground resistance.
Daktronics is not responsible for improper grounding or damage incurred as a result of
improper grounding.
Grounding methods must meet the provisions of all applicable local and national codes.
Inspect and verify all grounding methods meet the provisions of all applicable local and
national codes.
Proper grounding is necessary for reliable equipment operation and general electrical
safety. Failure to properly ground the sound system may void the warranty, disrupt
operation, damage equipment, and cause bodily harm or death.
