control the CXN with the Spotify Connect app on your
Apple iOS or
Android device. Access to Internet Radio and Spotify Connect requires the
Connect App for Apple iOS (7.1+) and Android (OS 4.0+) devices.
AirPlay Compatible: The Cambridge Audio CXN network audio player
is compatible with Apple's AirPlay technology. With AirPlay, the CXN 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.
- iTunes Streaming: The CXN network audio player is
able to stream audio from your computer's iTunes account via AirPlay
technology. When connected to the same network as a computer running iTunes,
the CXN can appear as an output option in the pop-up menu at the bottom
of the iTunes window. You can then browse your iTunes collection on your
computer & stream music to the Cambridge Audio network audio player. You will need a
Mac or Windows-based PC running iTunes (10.2.2 or later) connected to the same
network as the CXN.
- Apple Device Streaming: AirPlay also lets you
wirelessly stream music and music apps stored on your iPod touch, iPhone, or
iPad to the Cambridge Audio CXN. You will need an iPod touch, iPhone, or iPad
(running iOS 4.3.3 or later) connected to the same network as the CXN.
- Apple Remote App: 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 components or your computer to play, pause, skip, and stop
the songs in your iTunes music library. You will even see the iTunes music
information, including your track titles & artist info on your Apple device.
You will need an iPod touch, iPhone, or iPad (running iOS 7.0 or later)
connected to the same wireless network as the CXN.
UPnP Compatible: The Cambridge Audio CXN network audio
player is a UPnP (Universal Plug and Play) AV Client. Being a UPnP Client means
the it can connect to UPnP AV servers on a network and browse and playback their
music content. A connection to the internet is not strictly needed for this. The
CXN just needs to be able to connect to the server to access its content.
Most operating systems and/or music playback software now feature UPnP server
facilities built-in. This allow you to share the music on the computer's
hard-drive with Clients, such as the CXN. Your music library can include
digital music located anywhere on your home network such as shared folders on
your own computer (Windows or Mac), shared folders on another computer on your
network, or music stored on a Network-Attached Storage (NAS) device on your
network. Using UPnP, the CXN network player can connect to these devices and
play back, or 'stream' non-DRM music files via the network to your home
entertainment system. UPnP connection supports up to 24-bit/192kHz and Gapless
Note: Not all servers support serving of all audio
formats. Always make sure the server you choose also supports your formats
of choice. For example, Windows Media Server does not currently serve FLAC
USB Ports: The Cambridge Audio CXN network audio player is
fitted with two USB type-A ports (front/rear) to connect a USB flash
memory device or portable USB hard drive, and a rear-panel USB type-B port to
connect your Windows or Mac computer.
- Dual USB (Type-A) Ports: The Cambridge Audio CXN
features two USB (type-A) inputs for music playback from a USB flash
memory device or portable hard drive (up to 24-bit/192kHz). One USB port is
on the front-panel, while the other is on the rear-panel. Your USB
device must be formatted in FAT32 or NTFS format with non-DRM music files. The CXN
cannot supply greater than 500mA from the USB socket, itself. Good practice
is to create folders for Artists within which you should have sub folders
for each Album which then contain the tracks for that Album. Libraries with
thousands of tracks in one folder will progressively slow down the unit's media browsing.
- Asynchronous USB (Type-B) Input: A rear-panel
(type-B) port enables the CXN to be connected to your Windows PC or
Mac computer for playback of music files up to 24-bit/192kHz. The CXN will act as a very high-quality DAC/sound-card with
very low jitter for your computer, offering genuine Hi-Fi-quality
playback from your stored music and Internet radio. The CXN is both USB 2.0
(Hi-Speed) and USB 1.1 (Full-speed) USB port compatible. It will also work
with the new USB 3.0 ports where the PC will simply treat the CXN as if it
were a USB 2.0 or 1.1 device.
- PC Compatible: With the CXN switched to USB
Audio 1.0 (this is the default setting), the CXN will work with the
native Windows XP, Vista or 7 Audio 1.0 driver (no need to load any new
driver) and accept audio up to 24-bit/96kHz. With the CXN switched
to USB Audio 2.0, the CXN needs the Cambridge Audio USB Audio 2.0
Driver to be loaded and can then accept up to 24-bit/192kHz (and support
ASIO and WASAPI Exclusive, if required).
- Mac Compatible: No extra drivers are required to
connect your Mac computer. With the CXN switched to USB Audio
1.1, the CXN will work with the native Mac OS-X 10.5 (Leopard) or
above Audio 1.0 driver and accept audio up to 24/96kHz. With the
CXN switched to USB Audio 2.0, the CXN works with the native Mac OS-X
10.5 (Leopard) or above Audio 2.0 driver and can accept audio up to
here to download the Cambridge Audio USE Audio 2.0 Driver.

audio player supports many of the most popular formats via Network, UPnP, and USB
connection. Supported codecs include MP3 (16-320kbps), WMA (32-320kbps), AAC
(16-320kbps), WAV (16/24-bit; 32-192kHz), FLAC (16/24-bit; 32-192kHz), ALAC (16/24-bit:
32-192kHz), AIFF (16/24-bit; 32-192kHz), and Ogg Vorbis
Note: The CXN does not support WMA pro, WMA
lossless, RAW, AU, or other music file types not mentioned.
DSD Audio: The CXN will only support DSD x64 (AKA DSD64 or
64FS) via DoP (DSD over PCM). However this is only possible via USB connection
to a computer, using Class 2 USB Audio mode.
Digital Inputs: The Cambridge Audio CXN's optical
(toslink) digital input and coaxial (RCA) digital input allows it to act as
a high quality upsampling Digital-to-Analog Converter (DAC) to improve the sound
from other devices, such as set top boxes, games consoles, or disc players. The
optical and coaxial digital connections support up to 24-bit/192kHz, 2ch PCM
Optional Bluetooth Adapter: Simply plug in the Cambridge
Audio BT100 Bluetooth Audio Receiver (779BT100,
sold separately) into the network audio player's rear-panel USB (type-A) port
for wireless music streaming from many of today's most popular Bluetooth
supporting devices; such as Apple iPod/iPhone/iPad, Android smartphone/tablet,
Windows Phone/PC, Mac computer/laptop, and more. The BT100 even supports the
high-quality Bluetooth aptX CODEC, so you can stream audiophile quality music
from your Bluetooth-enabled Android (OS 4.0+) device to the Cambridge CXN.
Audiophile Performance: The
Cambridge Audio CXN network audio player provides audiophile
performance for outstanding reproduction of your streaming music files. The
CXN incorporates dual Wolfson digital-to-analog converters with
bit-perfect signal path and jitter suppression, as well as Cambridge's advanced
ATF2 upsampling technology and Dual Differential Earth Balanced Filter Topology
for all sources.
- Dual Wolfson Digital-to-Analog Converters: The
Cambridge Audio CXN employs two very high-quality Wolfson
WM8740 24-bit DAC ICs in dual-differential mode for excellent stereo
imaging. Since each channel has its own DAC to process information,
completely separate and symmetrical analog filter circuitry can be
implemented. This implementation allows both the left- and right-channel
circuitry to operate identically, ensuring the CXN delivers
fantastic sound-staging and stereo-imaging properties.
- ATF2 Upsampling Technology: The CXN
utilizes an asynchronous up-sampling process called "Adaptive Time Filtering
2nd Generation" that intelligently interpolates (converts) incoming audio
data from 16-24 bits (at any standard sampling frequency between 32-96kHz)
to 24-bit/384kHz for dramatically improved musical reproduction. ATF2 will
enhance the audio clarity, richness, and dynamic range of your compressed
- Dual Differential Virtual Earth Balanced Filter Topology:
The CXN uses Cambridge Audio's proprietary Dual
Differential Virtual Earth Balanced filter topology, configured as a
low-order two-pole liner-phase Bessel filter, in order to take advantage of
the achieved high-sampling rate. As a result your music will have extreme
linearity with greater dynamic range.
- Bit-Perfect Signal Path w/ Jitter Suppression: Music
stored on computers and other hard drives inherently suffers from jitter, so
the CXN implements a host of enhancements such as bit-perfect
signal path and jitter suppression to vastly improve the quality of digital
music playback. Total correlated jitter is less than 200ps.
All-Metal Chassis & Toroidal Transformer: The CXN network
audio player has an all-metal construction to ensure all components are
completely isolated for the very best possible performance. The CXN also uses a
large toroidal transformer to deliver perfect, low distortion power for all your
Digital Pre-Amplifier: By using a digital pre-amplifier, the audio
signal remains in the digital domain for much longer, compared to a traditional
analog integrated or pre-amplifier. Because the audio signal remains digital,
and is only converted to analog at the very last minute, it is far less
susceptible to analog signal deterioration. This means that the sound you hear
is as close as possible to the original recording.
DSP Controlled Volume: The CXN's digital pre-amplifier uses
a powerful 32-bit Blackfin DSP (Digital Signal Processor). Most digital
preamplifiers use "bit reduction" to adjust the level of the volume output,
however this results in much lower sound quality because digital information is
being cut out of the original audio signal. Instead, the CXN's digital
pre-amplifier uses the Blackfin DSP to control the level of the volume output,
meaning that the entire digital signal remains fully intact for the best
Balanced & Unbalanced Outputs: The Cambridge Audio CXN features both balanced (XLR) and unbalanced (RCA) audio outputs to
connect to a wide variety of home stereo receivers and amplifiers. The CXN features true balanced XLR analog audio outputs to connect high-end
home receivers and amplifiers. XLR is a higher-quality output that can reject
noise and interference with equipment with balanced inputs. The CXN also features an unbalanced stereo analog RCA audio output for connecting
your stereo receiver or amplifier. The unbalanced and balanced outputs are simultaneously
Digital Outputs: The CXN features two rear-panel digital
outputs; one optical (toslink) digital output and one coaxial
(RCA) digital output. These digital outputs allow pass-through of the selected digital source (no up-sampling performed). These outputs loop or
pass-through unprocessed digital audio from the selected digital input. Both digital outputs are always active and can be used to connect and run
equipment at the same time.
Ground/Lift Switch: When Grounded, the CXN is
connected to the earth connection of the PC directly. When Lifted the ground
connection is made via a network designed to break any hum loops that may be
caused by the source equipment. The Grounded setting is recommended, unless
audible hum is experienced.
IR Remote: The Cambridge Audio CXN includes a slim-line IR
remote control for wireless operation of the network audio player. The IR remote
also operates other Cambridge Audio devices, like CX series integrated amps
and AV receivers.
Cambridge Connect App: The free Cambridge Connect App for
Apple iOS (7.1+) and
Android (OS 4.0+) gives you full control of the CXN network audio player;
including power on/off, source selection, and volume up/down. The Cambridge
Connect App also gives you access and control over UPnP servers and NAS drives
connected to the same WiFi network, Internet Radio from across the world, select
online music services, USB media device plugged into the player, music stored on
your Apple iOS or Android device, and Bluetooth audio (requires BT100 adapter).
The free app also features a high-resolution display for album art and track
Front-Panel LCD: The network audio player's front-panel color LCD
displays album art and song/artist information. You can adjust the front-panel
LCD's brightness level.
Remote Connections: The Cambridge Audio CXN is fitted with
the following custom remote connections.
- IR Emitter In (3.5mm): 3.5mm minijack input that
enables modulated IR commands from multiroom or IR repeater systems to be
received by the CXN.
- Control Bus In/Out (RCA): The Control Bus RCA input
enables un-modulated commands from multiroom systems or other components to
be received by the CXN. The Control Bus RCA output provides
control bus output commands for further downstream units. This can be useful
if using the iPhone app to control the volume on a Cambridge Audio
