(2)The 2200 does not abruptly switch from one supply to the other. The output stage is permanently connected to the lower-voltage supply. The commutator is simply an electronic gate that opens when needed to allow current to flow from the high-voltage supply-quickly enough to supply the power needed for sudden full-power transients, but smoothly enough to guarantee that no switching transients are ever detectable in the output signal.
NAD is the world’s leading manufacturer of affordable high-quality stereo equipment.

NAD products are sold by a carefully selected network of dealers in twenty-nine countries around the world. If you haven’t seen the name be-fore, it is because NAD invests most of its money in engineering rather than advertising-relying on enthusiastic word-of- mouth publicity and an unbroken string of rave reviews in magazines to spread the news of the superiority of NAD’s designs. In keeping with its dedication to high value engineering and innovative product design, NAD is proud to introduce the Model 2200 Power Amplifier.
