d&b audiotechnik 30D - Power Consumption and Thermal Data; Measurement References and Power Figures

14.4. Current/power draw and thermal dissipation
Measurement references
Signal CF 12 dB: Represents 1/8th of the nominal power.
Signal CF 9 dB: Represents 1/4th of the nominal power; power
is limited to the nominal line current.
Continuous (cont.): Unlimited time. Thermal conditions may
affect power figures.
Maximum (max.): Values are measured 1 sec. after signal was
applied.
Sine wave (Max. 1 s / 10 %): 1 kHz Sine wave with
(voltage) CF 3 dB / 1.4, resp. Represents the highest line current
draw.
