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.
| Power Bandwidth (rated power into 4 ohms): |
