Current Draw is based on 4Ω loads across all outputs, with all outputs driving
the same source material (mono input signal).
8Ω loads would be approximately half the current draw typically.
Use the 12.5% column for calculating high-volume level operating conditions.
12.5% is 1/8th power pink noise, which is the equivalent of typical of program
material being played at onset of clipping levels.
The 33% Column is typical of the power draw when the amplifiers are
experiencing extreme clipping on program material.
The 100% Column is the theoretical maximum power draw with a pure sign wave
input.
NOTES: (1) Maximum continuous current draw is limited by the maximum
safety ratings of the SA-8 / IA-8. Short term power to the speaker terminals
are approximately double.
