AC Power Draw and Thermal Dissipation:
Pink noise 12dB crest factor, bandwidth limited 22Hz to 22kHz.
Typical line impedance used.
Measurements made with 120VAC mains. Data based on all channels driven.
Line current figures for 230VAC units derived by multiplying 120VAC figures by 0.5.
Line current figures for 100VAC units (not shown) are 1.2 times the line current figures of 120VAC units.
Power draw (”watts in”) of 100VAC units is the same as power draw of 120VAC units.
