Bi-wired stereo connections
The diagram below shows the 840W connected to an 840E bi-wired to
a pair of loudspeakers.
IMPORTANT! The metal strip connecting the low-frequency terminals to
the high-frequency terminals must be removed for a bi-wiring system.
Note:
In this configuration the 840W must be set to Stereo mode.

Advanced connections
As well as normal single-wired stereo operation (whether balanced or unbalanced), several other modes of operation are possible; Bi-wired Stereo, Bi-
Amped Mono and Bridged Mono and others.
In all of the following examples either balanced or unbalanced connections can be used, the principle is exactly the same for each type of connection.
For simplicity, we will show only the balanced connections in each example.
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 further 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).
