■Current Draw

1/8 power is typical of program material with occasional clipping. Refer to these ﬁgures for most applications.

1/3 power represents program material with extremely heavy clipping.

Test signal: Pink Noise, bandwidth limited from 22Hz to 22kHz

1W = 0.860kcal/h, 1BTU = 0.252kcal

Note that Line Voltage [V] x Line Current [A] = [VA], not equals to [W].

Inrush current: 11A (100V), 13A (120V), 25A (240V)
