3 Specifications of the Devices
3.13.10.3 Mode 3+1 with 4 Channel Amplifiers and Alive Contacts
The example uses 4-channel amplifiers. All channels use one power supply. Therefore it is necessary to
backup all 4 channel at one time. In other words: 4 backup channels are required.
This can be accomplished by connecting only 2 channels of the amp to a 3+1 group of the AX16. In the
diagram the channel 1+2 are indicated as „a“ and the channels 3+4 as „b“. The backup amplifier is number
4.
