Direct Digital Amplifier: 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; then compares the output to the input, and compensates for any
differences to achieve the perfect result. The high efficiency of NAD's 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.
- LSI's + Multi-Layer PCB's: The NAD 7050 direct digital amplifier
employs large scale integrated circuits (LSI) and multi-layer printed circuit
boards (PCB) to optimize speed and performance.
- NAD's Full Disclosure Power Ratings: NAD uses Full
Disclosure Power (FDP), the most demanding criterion for performance
measurement. FDP specifies distortion under the most extreme conditions of
low impedance loads and frequency extremes, rather than the simple and easy
1kHz @ 8 ohms test quoted by many of other manufactures. NAD uses this
stricter performance criterion because it more closely matches the demands
of real music and real loudspeakers. Maintaining specified distortion at 4
ohms and at 20Hz to 20kHz is a much more difficult achievement. The NAD D
7050 is rated at 50 watts x 2 channel (@ 20-20kHz, in 4-ohms, with 0.004%
THD).
Binding Post Speaker Terminals: The NAD D 7050 hybrid
digital amplifier is equipped with four binding post terminals to connect your
loudspeakers. The binding post speaker terminals will accept bare wire (up to
10AWG), banana plugs (single only), pin-connectors, and spade-connectors.
Analog Audio Outputs: The NAD D 7050 offers stereo RCA outputs that
can act as a pre-out to send an audio signal to a separate amplifier, or a
subwoofer output to send a low-pass audio signal (up to 200Hz) to a powered
subwoofer.
Built-in Headphone Amp: The D 7050 features an integrated
headphone amp with a 3.5mm headphone output jack to connect a pair of headphones
for private listening. A specially designed low noise headphone circuitry
accommodates a wide range of headphones, even 600-ohm studio models. Once
headphones are connected to the D 7050, your connected speakers will be turned
off.
Perfect Pitch: The PerfectPitch software program is
available as a free firmware upgrade for all D 7050 owners and can be downloaded
here.
Once installed, it is selected or bypassed using the D 7050 Remote App
available free at the Apple App Store. PerfectPitch
utilizes carefully developed DSP filters to raise accuracy to a new height of
perfection for PSB speakers. With PerfectPitch
engaged on the NAD D 7050, your PSB speakers sound smoother and more detailed in
the midrange with enhanced bass extension. The midrange is less forward and more
three-dimensional with superior depth and width. This creates a spacious and
airy sound field with improved image focus.
Variety of Digital Audio Sources
Wired or Wireless Network Connection: The NAD D 7050 is equipped with
dual network connection methods. There's an RJ-45 LAN (Ethernet) port for direct
wired connection to your home network, and there's also the built-in Wi-Fi
feature that includes Wi-Fi Protected Setup for safe and secure connection to your
wireless home network. Through either connection method, the D 7050 can playback
music on your network that is stored on your computer and playback music
directly from your Apple AirPlay iOS device or computer running iTunes.
- DLNA Certified: The D 7050 is DLNA (Digital Living Network
Alliance) 1.5 and Windows 7 compliant for audio networking. This means it's
easier for you to access and enjoy digital music stored on your PC or smartphone
(like Android). You can use your PC or smartphone to play high-bit rate music
content through your audio system.
- Apple Airplay: The NAD D 7050 is compatible with Apple AirPlay
technology. With AirPlay, the D 7050 can connect wirelessly to any
AirPlay-enabled Apple device. This allows you to stream music wirelessly
from your iPod touch, iPhone, iPad, or your computer's (Mac or PC) iTunes
library; via your WiFi network. Using the
Apple Remote App (Free download from iTunes) on your iPod touch, iPhone,
or iPad and your wireless home network, you don't even need to be in the
same room as the D 7050 or your computer to play, pause, skip, and stop the
songs in your iTunes music library. To use the AirPlay feature you need a
Mac or Windows-based PC running iTunes (10.2.2 or later) connected to your
wireless home network. Your iPod touch, iPhone, and iPad must have iOS 4.3.3
or later installed and connected to the same wireless home network.
Dual USB Inputs: The NAD D 7050 offers dual USB inputs; a
USB (type-B) port to connect your computer and a USB (type-A) port to connect
your Apple device.
- Asynchronous USB (type-B) Input: The NAD D 7050 features an
"asynchronous" USB (type-B) input to insure the lowest possible jitter (timing
errors) from your connected Windows or Mac computer. The D 7050's USB input
supports up to 24-bit/96kHz high-resolution music files on your computer. The D
7050 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 the
NAD
website.
- USB (type-A) Input For Apple Devices: The D 7050's USB (type-A)
input lets you connect your Apple iPod/iPhone/iPad using the connector cable
that came with your Apple device. The D 7050 supports playback of stored
music and music apps on your compatible Apple device. The USB (type-A) port
will also charged your connected Apple iPod or iPhone (but not iPad). Check
out the iPod compatibility chart for compatible iPod, iPhone, and iPod
models.
Bluetooth aptX Music Streaming: The NAD D 7050 offers
built-in Bluetooth aptX technology. Via Bluetooth, you can wirelessly stream
music from your smartphone, tablet, or laptop to the hybrid digital amplifier.
The D 7050 even supports aptX audio coding which delivers CD-quality sound
wirelessly over Bluetooth. The D 7050 is compatible with most Bluetooth devices
(such as Apple, Android, and Blackberry). However, due to the differences in
Bluetooth technology, some Bluetooth enabled devices may be incompatible,
function improperly, or may not support all features.
iPod Compatibility Chart: The NAD D 7050 is "Made for
iPod/iPhone/iPad" compatible and supports the following iPod, iPhone, and iPad
model features (as of 9/6/2013):
