Connections

When designing our amplifiers we include features that allow you to 

connect your system in various ways. The inclusion of features such as 

Pre-Out and Speaker B connections mean that you can flexibly configure 

your system depending on your requirements.

Important Note: When using a banana plug, make sure the speaker 

terminals are completely tightened before inserting the plug.

BASIC CONNECTIONS

The diagram below shows the basic connection of your amplifier to a CD 

player using the D3 coaxial digital input source and a pair of loudspeakers.

SPEAKER B CONNECTIONS

The Speaker B connections on the back of the amplifier allow for a second 

set of speakers to be used (i.e. speakers located in another room). The 

Speaker A/B button on the front panel scrolls through the selection of 

speaker A only, speaker B only, and speaker A and B together.

PREAMP OUT CONNECTIONS

The Preamp Out sockets are for connecting to the input sockets of a 

power amplifier or active subwoofer. The diagram below shows how to 

connect the amplifier to an active subwoofer via the Line In inputs on the 

subwoofer.

BALANCED AUDIO CONNECTIONS (CXA81 ONLY) 

The diagram below shows how to connect the CXA81 to the CXN Network 

player using the Balanced Audio inputs via three pin XLR connectors. 

The CXA81 can also be connected to non-Cambridge Audio sources with 

balanced outputs.

Line Output

Balanced connections in an audio system are designed to reject electrical 

noise, from power wiring etc, and also the effects of noise currents 

flowing through ground connections. The basic principle of balanced 

interconnection is to get the signal you want by subtraction, using a three-

wire connection. One signal wire (the hot or in-phase) carries the normal 

signal, while other (the cold or phase-inverted) carries an inverted version. 

The balanced input senses the difference between the two lines to give the 

wanted signal. Any noise voltages that appear identically on both lines 

(these are called common-mode signals) are cancelled by the subtraction. 

The CXA81 is designed to work at its highest performance when a balanced 

interconnect is used.

Note:

 To select the balanced input on the CXA81, press the A1 button twice 

on the front panel or on the remote control so that the A1 light on the front 

panel display lights up Orange. Repeatedly pressing the A1 button will 

toggle between balanced and unbalanced inputs.

USB AUDIO CONNECTION

The CXA USB input enables the playback of audio files or streamed 

programme from Microsoft Windows or Apple Mac OS X personal 

computers (and some Linux builds). When connected via USB the personal 

computer will identify the CXA as an audio device. Specifying the CXA in 

the computer’s audio control panel will enable it to play audio data either 

stored locally on the computer or streamed to the computer via a network 

or the internet.

Always turn the volume to minimum, switch to another 

input or turn the CXA off before plugging/unplugging 

cables to the USB input or whilst booting up/shutting 

down your PC/Mac.

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.
