Note: Power ratings are specified at 120VAC line voltages.
The M2600 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.
