Note
: Power ratings are specified at
120VAC (U.S. and Canada) and 240VAC
(Export) line voltages.
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 requires 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.
