Cambridge Audio Azur 840E user manual Mono Bridged connections, Important! 840W settings

Mono Bridged connections

The matching Azur 840W power amplifier features Mono and Bridged Mono settings that allow two (or more) 840Ws to be used as mono-blocs for high end systems. Below is an example using two 840Ws in Bridged Mono with an 840E.

In Bridged Mono mode each 840W drives one speaker across its output channels acting as a 500W mono amplifier instead of a 200wpc stereo one. One 840W drives the left speaker and the other the right. See the 840W manual for full details on Bridged Mono and other possible combinations.

The example below uses balanced connections from 840E to each 840W, unbalanced connections can also be used and the principle is the same.

Important! 840W settings

Before making any connections to the loudspeakers, make sure all power is turned off and only use suitable interconnects (e.g. banana plugs). Ensure that the positive (+) and negative (-) connections are wired as shown in the diagram.

When using balanced (XLR) connections, the Left and Right Input Type switches on the 840W must be in the ‘Balanced’ position. When using unbalanced (phono/RCA) connections, the Left and Right Input Type switches on the 840W must be in the ‘Unbalanced’ position.

Only use the Left Inputs on the 840W for Bridged operation.

In this configuration the Stereo/Mono switch on the 840W must be set to ‘Mono’ and the Mono mode switch must be set to ‘Bridged’.
