Note: Power ratings are specified at I2OVAC (U.S. and Canada) and 24OVAC (Export) line voltages.

The M-Series power ampli&rs 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.
