Note: Power ratings are specified at 120VAC line voltages.

The M•2600 power amplifier draws large amounts of current from the AC line with continuous sine wave test- ing. 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.
