1
Power Socket
Once all other connections are made, connect the supplied power cable to
the CXN power socket and to an appropriate mains socket. The CXN is now
ready for use.
2
USB Sockets
Wi-Fi Dongle
– Should be in the upright position as shown. Allows connection
to 802.11b/g or n networks (2.4 GHz will only be used for n networks).
Local Media
– Use to connect a USB storage device or another portable device
that is USB HD/flashdisk compatible containing music files. Alternatively an
optional Cambridge Audio BT100 Bluetooth Adaptor can be plugged in here
adding wireless streaming audio capability directly from most phones, tablets
and laptops. See later section for details.
Note: The USB ports are not intended for connection to Apple mobile devices,
no functionality, charging or otherwise is supported.
3
Ethernet
Ethernet port for connecting to a 10/100BASE-T local area network (LAN).
4
Digital Inputs
The CXN has two digital inputs in total featuring both S/PDIF co-axial and
TOSLINK optical sockets.
D1 TOSLINK Optical
– Use a high quality TOSLINK fibre optic interconnect
cable designed specifically for audio use. This input is suitable for 16-24 bit
content up to 192kHz (using high quality TOSLINK optical cable).
Note:
Although TOSLINK connections on the CXN work up to 192kHz with
high quality cables, TOSLINK is not usually recommended with sampling rates
above 96kHz.
D2 Coaxial
– Use a high quality 75 ohm digital RCA Phono interconnect cable.
This input is suitable for 16-24 bit content up to 192kHz.
5
Digital Outputs
The CXN digital outputs enable a separate DAC (digital to analogue
converter) or digital recording device to be connected. Refer to the ‘Operating
instructions’ section for more information.
Two concurrent digital outputs are available. Note that these outputs pass
through the currently selected audio source unprocessed, i.e. no volume
control or up-sampling is performed on the digital outputs.
Coaxial
– To obtain best results, use a high quality 75 ohm digital RCA
interconnect cable.
TOSLINK Optical
– Use a high quality TOSLINK fibre optic interconnect cable
designed specifically for audio use.

USB Audio In
A USB B type socket is fitted to the CXN to enable the playback of audio from
a personal computer running either Microsoft Windows or Apple Mac OS X
operating systems, most Linux distributions are also suitable.
Note:
Always use a high quality USB connection cable certified as USB Hi-
Speed. USB cable connections longer than 3m may result in inconsistent
audio performance.
Always turn the Volume to minimum, switch to another input
or turn the CXN off before plugging/unplugging cables to the
USB input or whilst booting up/shutting down your PC/Mac.
Ground Lift Switch
The Ground Lift Switch enables the USB interface earth to be disconnected
from the CXN chassis earth. Disconnecting (lifting) the earth can be useful if
electronic hum is heard through the speakers. The switch should otherwise be
left in the Ground position.
7
IR (Infra Red) Emitter In
A 3.5mm mini-jack socket that enables modulated IR commands from multi-
room or IR repeater systems to be received by the CXN.
Note:
Commands received by the IR Emitter In socket are not looped out of the
Control Bus. Refer to the ‘Custom Installation’ section for more information.
8
Control Bus
In
– An RCA phono socket that enables un-modulated commands from multi-
rooms systems or other components to be received by the CXN.
Out
– An RCA phono socket that provides control bus output commands for
further downstream units. This can be useful if using the iPhone/Android app
to control the volume on a CXA-60/CXA-80 amplifiers and Azur amplifiers.
9
Balanced Audio Output
The CXN features balanced outputs on two XLR sockets. Balanced outputs
provide slightly better audio performance and can reject cable-borne noise
and interference when used with equipment with balanced inputs.
Note:
XLR connectors should be wired as follows:
Pin 1: Ground
Pin 2: Hot (in-phase)
Pin 3: Cold (phase-inverted)
10
Line Output
A conventional RCA phono stereo output for connection to the line-level
inputs of an amplifier. Use a high quality stereo RCA phono interconnect cable
intended for analogue audio signals.
