Cambridge Audio CXN 业主指南

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.

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.

The CXN digital outputs enable a separate DAC (digital to analogue

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.

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.

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

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.
