NU2-WH

NU2-WH is an acronym for non-uniform 2nd order, with hybrid frequency components, and signifies an advanced, cutting-edge amplifier technology and is currently the industry standard for many high-end audio applications. The technology was originally developed by the Canadian audio manufacturer North American Digital Research (NADR) for a high-quality music playback system intended for use in both studios and home audio systems.NU2-WH uses a two-stage circuit topology, where the input circuit is configured as a non-uniform 2nd order filter, and the output circuit is a hybrid of second and fourth-order type structures, used in conjunction with a transformer to increase the dynamic range. This hybrid technology is used to achieve an exceptionally high audio reproduction quality, especially in terms of clarity and dynamic range.The non-uniform 2nd order filter is a configuration of resistors and a single capacitor in series arranged in such a way that low and mid-range frequencies can be accurately reproduced, while eliminating unwanted higher frequency noise. The filter has two operational modes - either an inverted or non-inverted signal response depending on the setting of its control switch. The hybrid frequency component in the output stage allows the unit to accurately reproduce the frequencies from lower to higher range levels without introducing distortion or transient noise.NU2-WH amplifiers are widely used in professional audio applications such as recording studios, sound systems, karaoke systems, and home audio systems. They are becoming increasingly popular for home theater system builds because of their superior audio reproduction quality and extensive frequency range. They are also favored by audiophiles because of their low noise and distortion figures.In terms of working principle, NU2-WH amplifiers are considered voltage source devices, meaning they draw current from a voltage source and serve as a means of power amplification. Power is drawn from the input to the output via an integrated power transformer. The transformer passes the input signal through the primary winding and then the amplified output is passed through the secondary winding. This process is repeated multiple times until the output voltage significantly amplifies the input voltage level.NU2-WH amplifiers boast a very wide frequency response, which is one of their main advantages over regular amplifiers as they can accurately reproduce a larger range of frequencies, making for an audible difference in sound reproduction quality. They are also highly efficient; they generate very low heat output and have low power dissipation, making them an ideal option for any application that requires an amplifier to work at low levels for extended periods of time.Overall, NU2-WH is a cutting-edge amplifier technology which provides excellent sound quality in a highly efficient and durable package. It is a great choice for professional and home audio applications, as it is designed to accurately reproduce a wide range of frequencies with minimal distortion or noise.
