Current draw at full power is measured with a 1 kHz sine
wave. However, it does not represent any real-world
operating condition.
Current draw at 1/3 of full power is measured with pink
noise as a signal. It approximates operating with music or
voice with very heavy clipping and a very compressed
dynamic range.
Current draw at 1/8 of full power is measured with pink
noise as a signal. It approximates operating with music or
voice with light clipping and repesents the amplifier's
typical "clean" maximum level, without audible clipping.
Use these figures for typical maximum level operation.
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 100-volt operation, see the companion sheets. For typical usage,
use the
idle
and
1/8 power
figures. Where an asterisk (*) appears, the data was not available at press time. The designations "na" and "nr" respectively mean "not applicable" to the particular
amplifier model and "not rated" for the particular load impedance.
