What about nad amplifier in Britain? Who has heard of it?

NAD can be said to be a British brand, because it was founded in Britain by Jiri Janda in 1972. It is also a Danish brand: Peter Lyngdorf, a Danish audio investment legend, took over NAD, a subsidiary of AudioNord International, and then transferred it to Rumbrook Group in Pickering, Ontario, Canada. Therefore, NAD combines the fever elements of Britain, Denmark and North America, and adheres to the concept of simplicity and true reduction.

A prominent feature of NAD's technology is its PowerDrive power supply and power boosting scheme, which is specially used to control low-impedance horn units. This technology even has 2? The speaker unit can still be controlled freely. This technology is completely different from the common "big current, big power and big dynamic" technology. This is also inherited the early improvement technology of NAD-controlling the speaker unit with small energy can also achieve the effect of restoring high-fidelity sound. The patented PowerDrive technology was recognized by the relevant technical departments of the US Federal Trade Commission at that time. 、8? It is really exciting to achieve "zero distortion" in the impedance state, especially near the frequency of 1KHz.

PowerDrive technology is also embodied in "airbag power technology", or "dynamic power"-the output power of the amplifier can be changed according to the state of the sound source signal, especially when a large dynamic signal comes, its output power can be doubled to compensate for the loss of dynamic distortion in the signal chain, so it is easier to obtain a surging and shocking large dynamic effect.

It is not easy to answer this question. Please adopt it if it helps. Thank you! !
