C 700 BluOS Streaming Amplifier

The way people discover and experience music has shifted
profoundly. Today’s listeners can stream music from vast catalogues over the
Internet, often with better sound quality than discs can deliver. To simplify
music selection, streaming services offer discovery tools like curated
playlists and recommendation engines. Wireless multi-room audio lets listeners
enjoy music throughout their homes. The NAD C 700 BluOS Streaming Amplifier is
a compact, “just add speakers” solution that embraces all the possibilities of
the streaming age, offering state-of-the-art amplification that will transport
you to your favorite musical destination.


A Feast for the Senses

The C 700 BluOS Streaming Amplifier was designed for the
streaming age. Connect your speakers, then use the intuitive BluOS app on your
smartphone, tablet, PC, or Mac to select the music you want to hear. It will
sound glorious.

Through its HybridDigital UcD output stage, the C 700 can
deliver 2×80 watts of continuous power and 2×120 watts of instantaneous power,
for effortless reproduction of musical transients. NAD’s highly efficient
HybridDigital UcD amplifier design is renowned for ultra-low noise and
distortion through the entire audioband, regardless of the loudspeaker load.

Thanks to its elegant, minimalist design and premium
materials, the C 700 will engage all your senses — not just hearing, but sight
and touch as well. The amplifier is housed in a solid aluminum case, with a
smooth glass front panel and 5″ high-definition color display that shows album
art, track progress, and system settings.

Following menus on the C 700’s color display, you can adjust
amplifier settings with the control knob and navigation buttons on the front
panel. And the C 700 can learn commands from your favorite remote control.

A Modern Classic

With built-in Ethernet and Wi-Fi, and a network streamer
based on the rich, robust BluOS software platform, the C 700 has everything you
need to play music through your favorite speakers. Using the BluOS Controller
app, you can cue up music from dozens of different streaming and Web radio
services, or play music stored on an external drive connected to the C 700’s
USB port.

Like all BluOS-enabled components, the C 700 supports
high-resolution audio to 24-bit/192kHz, and has full MQA decoding and rendering
capability. With these features, you can enjoy lossless and high-resolution
audio from services such as Amazon Music Ultra HD, Deezer, Qobuz, and Tidal.

The C 700 supports Spotify Connect and Tidal Connect, so you
can control playback from the apps for those services; and Apple AirPlay 2, so
you can stream music from Apple devices and iTunes libraries. You can also cue
up music by voice, using the Amazon Alexa, Apple Siri, or Google Assistant

NAD offers software tools that allow smart-home specialists
to integrate the C 700 into home-automation systems from Control4, Crestron,
Elan, RTI, and others. This allows control of music playback, along with other
home systems like lighting, shades, HVAC, and security.

Well Connected

The C 700 has two pairs of RCA analog inputs, as well as
coaxial and optical digital inputs, for connecting disc players, game consoles,
media adapters, and other components. There’s also an HDMI-eARC port for
connecting an HDTV with HDMI-ARC support. This allows the C 700’s volume
setting to be adjusted from the TV’s remote.

In addition to the loudspeaker outputs, the C 700 has a
subwoofer output jack. Using the BluOS app, you can set low- and high-pass
crossover settings, for a seamless blend between the subwoofer and main

The C 700 also has two-way aptX HD Bluetooth, so you can
listen to music through wireless headphones, and stream audio from any smart

The Legend Continues

There are many ways to enjoy the NAD C 700 BluOS Streaming
Amplifier. It can serve as the hub of a standalone music system; or function as
part of a BluOS whole-home music system with as many as 63 zones, with full
support for high-resolution audio. The C 700 can also be combined with other AirPlay
2 components for whole-home music.

With the C 700, you can play music from your favorite
streaming services and Web radio stations, or from a music library on a USB
drive, through your loudspeakers; or you can listen though wireless headphones.
The C 700’s digital and analogue inputs will accommodate your legacy

Ever since NAD introduced the legendary 3020 integrated
amplifier in 1978, the NAD brand has been renowned for value, performance, and
innovation. With the C 700 BluOS Streaming Amplifier, NAD has reinvented that
tradition for the streaming age.
