azur 840W

Bi-amped dual mono connections

The 840W features Mono and Bi-Amped 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 Bi-Amped Mono with an 840E.

In Bi-Amped Mono mode each 840W drives one speaker.

Important 840W settings

Only use the Left Inputs on the 840W for Bi-Amped 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 ‘Bi-Amp’.

The metal strip connecting the low-frequency terminals to the high- frequency loudspeaker terminals must be removed.

Bridged dual mono connections

The 840W 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 840W’s 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.

Important 840W settings

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’.
