"Current draw" is the amount of AC current an amplifier demands while it is operating. Measurements are provided for various loads at idle, 1/8 of average full power, 1/3 of average full power, and full power, with all channels driven simultaneously. 

The figures shown below are for 120 VAC usage; for 230- and 100-volt operation, see the companion sheets. For typical usage, use the idle and 1/8 power figures.

Each of QSC amplifiers has a chart like the one shown below with its appropriate ratings.
