NAD D 1050 Stereo DAC/headphone amplifier
The NAD D 1050 USB DAC is the best way to add Computer Audio and HD Digital to your component hi-fi system. Both the digital and the analogue circuits are highly optimized, and are based on techniques developed and proven over NAD’s history. The digital inputs cater to many different digital sources. SPDIF inputs support balanced AES/EBU, coaxial and optical connectors. The USB input is special; supporting USB Audio Codec 2.0 allowing for 192kHz signal transmission, its asynchronous operation mode uses the D 1050’s high precision clock to control the output of the connected USB device for lowest possible jitter. A choice of true balanced or low impedance single-ended outputs allows connection to a broad range of preamps. A discrete low impedance headphone amplifier rounds out the capabilities of this compact and affordable DAC. External DAC: The NAD 1050 is a high performance external DAC which lets you stream your high-resolution music files on your computer (via USB) to your home audio system (via RCA or XLR) with exceptional sound quality. It also provides optical and coaxial digital inputs for connection of other digital audio devices (like your Blu-ray or CD player). In addition an integrated headphone amplifier lets you listen to your digital music files privately with great sound.
Delta-Sigma 24-Bit/192kHz Architecture: The NAD 1050 employs a Delta-Sigma 24-bit/192kHz digital-to-analog converter (DAC), active oversampling filters, and separate precisions clocks. This configuration effectively reduces jitter (digital timing errors) to prevent unwanted noise and distortion, while maintaining a linear phase response and natural sound. All your digital music is bit perfect with nothing upscaled or downscaled. Ultra-Short Signal Paths: The D 1050's analog and digital circuits use ultra short impedance-controlled signal paths made possible by multi-layer circuit boards and micro-miniaturized surface mount components which are soldered with lead-free high silver content solder. These details contribute to reduced noise and excellent sound quality.
Asynchronous USB (Type-B) Input: The NAD D 1050 features an "asynchronous" USB (type-B) input to insure the lowest possible jitter (timing errors) from your connected Windows or Mac computer. The D 1050's USB input supports up to 24-bit/192kHz high-resolution music files on your computer. The D 1050 is compatible with Mac OS X Snow Leopard (version 10.6) or later version; no additional USB driver required. Its also compatible with Windows (XP service pack 2 or higher and 7); additional USB driver download required from NAD website.
Optical/Coaxial Digital Inputs: The NAD D 1050 is fitted with two digital coaxial (RCA) inputs and two optical (toslink) digital inputs for connection of your digital audio sources; like Blu-ray/DVD players, CD/SACD players, satellite/cable boxes, or network audio receivers. The D 1050 only supports a PCM digital audio signal (not Dolby Digital/DTS).
Balanced & Unbalanced Analog Outputs: The NAD D 1050 is fitted with both balanced (XLR) and unbalanced (RCA) analog audio outputs to connect to your integrated amplifier or AV receiver. Output impedance is extremely low, minimizing the effect of connecting cables and keeping noise vanishingly low.
Discrete Headphone Amp: The D 1050 also includes a premium discrete headphone amplifier output with a high-quality volume control for connection of a set of headphones. A specially designed low noise headphone circuitry accommodates a wide range of headphones, even 600-ohm studio models. When headphones are connected, the DAC's unbalanced and balanced audio outputs are muted.
External Power Supply: The NAD D 1050 includes an external power supply to provide isolation from ultra-precise audio circuits for better audio performance and less distortion.
Input: 100-240V~50/60Hz, 0.75A
Output: 5.0V - 400mA/20W
