Note: The M•1200/M•1400 power amplifiers draw large amounts of current from the AC line with continuous sine wave testing. Accurate measurement of power re- quires a steady and stable AC supply. This means the line impedance must be very low to insure that the peak AC line voltage does not sag to less than 97% of its value.
If driving highly reactive loads, we recommend that the limiter circuit be engaged.
