Cambridge Audio AXR100D Manual page 12

When using a banana plug, make sure the speaker terminals are completely tightened before inserting the plug.
The speaker terminals will need to have the round dust caps removed before you can insert a banana plug into them.
BASIC CONNECTIONS
Any 'line level' source equipment can be connected to the audio inputs on the AXR (A1 to A3).
The diagram below shows the basic connection of the AXR100D to a CD player using the A1 analogue input and a pair of loudspeakers.
The diagram below shows the basic connection of the AXR100D to a turntable via the Phono input.
This unit has a built-in Phono preamplifier (Phono Stage), so if your turntable does not possess its own Phono Stage, you may connect the record player
to the input on the rear of the unit marked 'Phono'.
If your turntable does have a built-in Phono stage or you are using an external version, you should connect to any of the other analogue inputs, as the
'Phono' input may produce an unwanted distortion.
Note: Do not connect a non-phono source to the phono input.
