Frequency Response 20Hz - 20kHz
Notes High Current for Low Impedance - Many loudspeakers have a complex impedance curve that is lower than 8 ohms at some frequencies. The lower and more complex the impedance, the more output current the amplifier must deliver. A special rear panel switch optimizes NAD amplifiers for 8 ohms or for low impedances [ 2 - 6 ohms ].
Adaptive Soft Clipping - NAD premiered the use of Soft Clipping in solid state amplifiers, gently rounding off waveform corners when the amplifier is overdriven. This eliminates any harsh power-supply buzz and high-order distortion.
