Rear Panel Connections - Cambridge Audio CXN v2 User Manual

Rear panel connections

1. POWER SOCKET
Once all other connections are made, connect the supplied power cable to
the CXN v2 power socket and to an appropriate mains socket. The CXN v2
is now ready for use.
2. USB SOCKETS
Wi-Fi Dongle – The Wi-fi dongle is pre-fitted. Please leave connected.
Allows connection to 802.11b/g or n networks (2.4 GHz will only be used
for n networks). If you are using this CXN v2 with Wi-Fi please make sure
your unit is positioned within range of your wireless router.
Important note:
Do not connect/disconnect the Wi-Fi dongle when the unit is on.
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).
Your unit will automatically default to an Ethernet connection if one is
made.
4. DIGITAL INPUTS
The CXN v2 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 v2 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 v2 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.

6. USB AUDIO IN
A USB B type socket is fitted to the CXN v2 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.
Ground Lift Switch
The Ground Lift Switch enables the USB interface earth to be disconnected
from the CXN v2 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 v2.
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 v2.
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 v2 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.

Always turn the Volume to minimum, switch to another
input or turn the CXN v2 off before plugging/unplugging
cables to the USB input or whilst booting up/shutting
down your PC/Mac.
