Input (Source) connections
Inputs 1 and 2 on the 840E feature either unbalanced (phono/RCA) or
balanced (XLR) connections. The 840E is designed to work at its highest
performance when a balanced interconnect is used.
The diagrams below shows the 840E pre-amplifier connected to an Azur
840C CD player in unbalanced (Figure 1) and balanced (Figure 2)
configurations. The 840E can also be connected to non Cambridge
Audio sources with balanced outputs.
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.
Make sure the Balanced/Unbalanced switch for Inputs 1 and 2 are set

Note:The 840E features a Trigger Out which can alternatively be used
to control the 840W’s Standby/On status if desired. Again, the
procedure is simply to connect the two units together (using a 3.5mm to
3.5mm mono mini-jack lead in this case).
Control Bus is the recommended method when using an 840E and other
Cambridge Audio equipment with Control Bus In/Out.
Trigger In/Out can be useful if the 840W (and indeed 840E) is desired
to be controlled by other equipment that features trigger outputs
