2 1.2 SPECIFICATIONS 1.2.1 STEREO SPECIFICATIONS Output Power 80 watts per channel minimum RMS (both channels operating) into an 8 ohm load over a bandwidth of 1Hz-20KHz at a rated RMS sum total harmonic distortion of 0.05% of the fundamental output voltage. 90 watts RMS into 8 ohms, per channel, both channels operating, 0.1% total harmonic distortion. Less than 0.001% from 20Hz-400Hz, and increasing linearly to 0.05% at 20KHz at 80 watts RMS per channel into 8 ohms. Less than 0.05% from 0.01 watt to 0.25 watts and less than 0.01% from 0.25 watts to 80 watts into 8 ohms, per channel. 6 volts per microsecond (slewing rate is the maximum value of the first derivative of the output signal, or the maximum slope of the output signal). Greater than 400, DC-400Hz into 8 ohms. Less than 15 milliohms in series with less than 3 microhenries. Rated for 8 ohm usage; safely drives-any load including completely reactive loads, 20.6±2% or 26.3±.2dB at maximum gain. 1.19 volts ±2% for 80 watts into 8 ohms. Unbalanced, dual channel.
