D 3020 V2

Hybrid Digital DAC Amplifier

The original NAD 3020 introduced a generation of music lovers to true high-fidelity sound. In the 1970’s, over a million people rediscovered their music when they placed a NAD 3020 between their turntable and loudspeakers. This little gem outshined amplifiers costing 10 times more with its big, warm, detailed sound. Today, the source is more likely to be a computer or smartphone than a turntable, but the ability to choose speakers that perfectly suit one’s taste is still a compelling argument for upgrading to an NAD amplifier. The D 3020 starts with the original NAD 3020 concept and brings it straight into the 21st century using the latest high-speed digital technology. Now with V2, we have refined the looks and added a Phono input for vinyl playback.

最初的NAD 3020将一代音乐爱好者带入了真正的高保真声音。在20世纪70年代，超过一百万人将NAD 3020放在转盘和扬声器之间，重新发现了他们的音乐。这颗小宝石以其宽大、温暖、细腻的声音胜过了10倍的功放。如今，音源更多的是电脑或智能手机，而不是转盘，但能够选择完全符合自己口味的扬声器，仍然是升级为NAD功放的有力理由。D 3020从最初的NAD 3020概念出发，用最新的高速数字技术将其直接带入21世纪。现在的V2，我们对外观进行了改进，并增加了黑胶播放的Phono输入。

Reinventing an Icon

By adapting to today’s media sources and using state-of-the-art digital technology for the new world of digital music, the D 3020 puts a completely modern spin on a revered icon. The original designer of the 3020, NAD’s Director of Advanced Technology, Bjorn Erik Edvardsen, has been pivotal in developing the D 3020 for the new digital generation. Offering an excellent quality 24/192 DAC with 8 channels mixed to 2 for improved resolution, the D 3020 V2 represents the same kind of value-bending innovation that gave the original 3020 its legendary overachieving phono stage.

重塑一个图标

通过适应当今的媒体来源，并利用最先进的数字技术，D 3020为数字音乐的新世界带来了全新的数字音乐世界，使D 3020在一个受人尊敬的标志上焕发出了全新的现代感。作为3020的原创设计者，NAD的高级技术总监Bjorn Erik Edvardsen在开发D 3020的过程中发挥了重要作用。D 3020 V2提供了一个质量卓越的24/192 DAC，8个声道混合为2个声道以提高分辨率，D 3020 V2代表了同样的价值创新，这也是最初的3020的传奇性的超音阶

More Connected

The D 3020 offers inputs for your digital and analogue sources. Coaxial and optical inputs allow many different digital sources to be connected, from CD and DVD players, to set top boxes, media streamers like AppleTV, or satellite and cable receivers. There are also analogue inputs including a sophisticated MM Phono input. Far from just another set of sockets, this Phono stage includes highly accurate RIAA equalization, an Infrasonic Warp Filter, and features both high overload margins and extremely low noise. With V2 we’ve also added a PreOut for increased connectivity in the output stage.

更多连接

D 3020提供了数字和模拟信号源的输入。同轴和光纤输入允许连接许多不同的数字信号源，从CD和DVD播放机、机顶盒、媒体流媒体播放器（如AppleTV）或卫星和有线电视接收机等。此外，还有模拟输入，包括一个复杂的MM Phono输入。这款Phono级不仅仅是另一套插座，它还包括高精度的RIAA均衡，Infrasonic翘曲滤波器，并具有高过载余量和极低的噪音。在V2中，我们还增加了一个Pre-Out，以增加输出级的连接性。

Power that Delivers

Power output may sound small at 30W per channel, but like all NAD amplifiers this is very misleading, as a properly designed 30W amplifier can sound superior to a 100W amplifier from a lesser brand. With its very small form factor, the D 3020 will astound many for its ability to drive difficult loudspeakers to satisfying levels without adding noise or distortion.

带来的力量

每声道30W的功率输出可能听起来很小，但就像所有NAD功放一样，这是很有误导性的，因为一个设计得当的30W功放可以比小品牌的100W功放听起来更出色。D 3020的外形尺寸非常小，它能在不增加噪音或失真的情况下，将使许多人感到震惊，因为它能将困难的扬声器驱动到令人满意的水平。

Real World Performance

NAD rewrote the rules for amplifiers when designing the original 3020. Instead of letting laboratory test equipment have the last word, we made sure that we could properly drive real loudspeakers with real music for the real world. The D 3020 lives up to this promise through a unique implementation of NAD PowerDrive™ developed by Edvardsen, that allows low impedance drive (current) and high dynamic power (voltage) at vanishingly low distortion levels. This refinement of PowerDrive combined with a precision soft clipping circuit, lets the D 3020 sound even more powerful than it already is. An innovative Bass EQ circuit helps small speakers sound big without overdriving or damaging ported woofers.

真实世界的表现

NAD在设计最初的3020时，重写了功放的规则。我们没有让实验室测试设备说了算，而是确保我们能够正确地驱动真实的扬声器，为真实的音乐提供真实的音乐。D 3020通过Edvardsen公司开发的NAD PowerDrive™独特的实现，实现了这一承诺，使D 3020能够在低阻抗驱动（电流）和高动态功率（电压）的同时，实现了极低的失真。PowerDrive的这种改进与精密的软削波电路相结合，使D 3020的声音比原来更有力量。创新性的低音均衡电路帮助小型扬声器在不过度驱动或损坏门式低音单元的情况下，使其听起来更有力量。

Stream with Bluetooth

The D 3020 V2 delivers the convenience of wireless streaming with its Bluetooth® capability. Stream all your music from a smartphone, tablet, or laptop. The D 3020 even supports the highest audio quality Bluetooth, aptX®, which is becoming ever more popular for its excellent sound quality and low power consumption compared to Wi-Fi.

蓝牙流

D 3020 V2 通过蓝牙功能提供了无线流媒体的便利。从智能手机、平板电脑或笔记本电脑上串流所有音乐。D 3020甚至还支持最高音质的蓝牙，即aptX®，与Wi-Fi相比，它因其出色的音质和低功耗而越来越受欢迎。

Mean and Green

The D 3020’s highly efficient design wastes less energy, requiring only 20% of the power needed by traditional Hi-Fi amplifiers. It’s like trading in a gas guzzling car for a hybrid vehicle. Standby power consumption is a miniscule <0.5W. NAD has taken amplification to new lows, with lower distortion, lower noise, and lower power consumption. NAD’s major focus is to find new technology that improves musical performance while consuming less power and using fewer non-renewable resources in manufacturing.

平均数和绿色

D 3020 的高效设计浪费了更少的能源，只需要传统Hi-Fi功放所需的20%的功率。这就像把油耗高的汽车换成了混合动力汽车。待机时的功耗仅需极少的 <0.5W.
