Correct Speaker Wattage Tapping
When setting speaker taps, total combined speaker wattage should not exceed total wattage output of the amplier minus 20% headroom
buer space. This allows the speakers to perform at full peak wattage without audio clipping*

*Clipping is a form of waveform distortion that occurs when an amplier is overdriven and attempts to deliver an output wattage beyond its maximum capability. Loss of
audio will occur as a result of clipping.
