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
to the connection type you wish to use.

Power syncing (On/Standby control)

When going in/out of Standby mode the Azur 840E pre-amplifier can (if
desired) automatically control the 840W when connected via the Control
Bus sockets (the Control Bus sockets are colour-coded orange on the
rear panels of compatible Azur models). For this feature to work the
units must be connected together by RCA/phono leads. No futher setup
is necessary. 

Connect the Control Bus Out from the 840E to the Control Bus In on the
840W. Continue the chain to other Azur models if it is required to sync
more units (refer to the 840E’s own manual for more information as this
requires some setup).

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
(Custom install and/or Multi-Room Systems etc).
