This article describes different redundancy concepts for PA system in general and for Exigo.
The Exigo system supports several redundancy functions, allowing even a single system to become more redundant.
Depending on different claims that projects may have, there may be a need for one or more redundancy functionality.
Backup Amplifier
This is also refereed to as hot standby amplifier.
The basic concept is that if one amplifier fails, a backup amplifier will take over.
Exigo ENA Amplifiers have inbuilt support for backup amplifier switch-over where one amplifier can be designated as backup for up to six other amplifiers.
More information about this feature can be found here.
A-B Wiring
To avoid loosing coverage in a area if an amplifier fails, it is possible to design the solution with A-B wiring.
The concept is that you design the speaker layout in a given area (typically a zone) so that the speakers are managed from two different amplifiers.
If one of the amplifiers fails you still have audio in 50% of the speakers.
