8 AC Power Draw and
Thermal Dissipation

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. Line current figures for 230VAC units derived by multiplying 120VAC figures by 0.5.
Data based on all channels driven.
At Idle (8.4 Ohm mode )
At Idle (70/100V mode)
1/8th Power Pink Noise
Typical of program material
just at clip.
1/3rd Power Pink Noise
Typical of program material
with severe clipping.
