1544BAS Backup Amplifier Switch

The 1544BAS is a backup amplifier switching module capable of switching up to four (4) loudspeaker loads from a primary power amplifier to a backup when a failure is detected. In stand-alone mode, logic outputs from the primary amplifier are used to trigger the switching of each individual channel to the backup amplifier. In network control mode, switching is determined by the IED GLOBALCOM system supervision sub-system. In network control mode, multiple 1544BAS units can be used to switch multiple primary amplifiers to a single backup amplifier unit. When used in this manner, all switching logic is accomplished through network commands and the logic inputs are not used.
