This includes the K3's and K2's internal 100-W amps as well as the KXPA100. They will certainly run from lower voltages -- down to about 10.5 to 11 V -- but for home use, we recommend setting the DC supply to 14.0-14.2 V. They'll run from as high as 15 V, though again, around 14 V optimizes power output, IMD levels, and efficiency.
