Amplifier Current Draw—100 VAC
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 on this sheet are for 120 VAC usage; for 230- and
