NAD D 7050 Direct Digital Network Amplifier

Introduction

If you have a computer or smart phone running iTunes, and a home Wi-Fi network, just add the D 7050 and your favorite loudspeakers. You'll now have a state-of-the-art audio system in a stylish and compact package the fits anywhere in your home or apartment. Wireless access is universal as we also support Bluetooth aptX for point-to-point streaming without a network.

INNOVATIVE TECHNOLOGY
The D 7050 combines NAD's most advanced digital platform, the Direct Digital technology first introduced in our $6,000 award-winning Masters Series M2 amplifier, with Apple's AirPlay Wi-Fi streaming technology to create the ultimate plug 'n play solution for wireless music in your home. We don't just speak Apple, we can also stream any UPnP audio content on your home network. Don't have a network? You can also stream directly from your smartphone or laptop using the latest Bluetooth High Fidelity Codec; aptX. You can also play from a wired connection from your computer or from a USB Drive. The only thing missing is an analog input; you see there are no analog circuits in the D 7050! The uncompromising performance of the D 7050 is made possible, in a large part, by the elimination of noisy and resonant analog circuits that can obscure musical detail and soften musical transients.

DIRECT DIGITAL
Direct Digital means there are no noise and distortion producing analog circuits in the D 7050; your music remains digital right up to the speaker outputs. NAD's Direct Digital technology of the D 7050 performs all preamplifier functions in the digital domain using sophisticated software to control all aspects of performance. Digital is converted to Analog by a simple passive two-pole reconstruction filter located right at the speaker outputs. This radical design is the worlds' first successful closed loop digital amplifier. Closed loop means that we compare the output to the input, and then compensate for any differences to achieve a 'perfect' result.

SMALL IS BEAUTIFUL
We've packed 4 times the amount of circuitry into ¼ the space of our traditional analog Receivers. You see, high speed digital circuits perform better with very short signal paths. For this reason we use large scale integrated circuits (LSI's) and multi-layer printed circuit boards to optimize speed and performance. The high efficiency of our Direct Digital amplifier technology significantly reduces the size of the heat sinks and power supply, which are physically large in high performance analog amplifiers, while offering improved sound quality. The result is a cool running, compact powerhouse with remarkable performance.
