The Amplifiers are designed for perfect integration into the Ambient System solutions. Thanks to their flexibility, they can also be used for any other Public Address and Voice Alarm applications. These amplifiers have been developed to meet the specific requirements of the EN 54-16 standard for safety installations.
The ABT-PAXXXXB is a family of 2U, rack mountable, 8-channel (ABT-PA8080B, ABT-PA8160B) and 2-channel (high power ABT-PA2650B) class-D transformer isolated power amplifiers for 50 V and 100 V distributed loudspeaker systems. Amplifier ABT-PA8080B can deliver up to 8x 80W, for ABT-PA8160B and ABT-2650B delivering power increases respectively to the 8x 160 W and 2x 650 W. In a bridged mode amplifier channels are combined and can deliver 4x 160 W for ABTPA8080B, 4×320 W for ABT-PA8160B and 1x 1300 W for ABT-PA2650B.
These amplifiers have 48 VDC input which allows to connect with battery backup system for maximum availability and durability in an voice evacuation system.
The ABT-PAXXXXB amplifiers are powered from external power supply module ABTPS48800 working in a block. The current from block is distributed to individual amplifiers through the „power manager” ABT-PSM48 (device includes a battery charger and is in compliance with EN 54-4).
The ABT-PAXXXXB amplifiers are prepared to connect an external audio source by using up to the eight BGM inputs (1 per channel) with the sensitivity level regulation. In the alarm mode the BGM inputs have to be muted by shorting the lines from BGM CTRL to the ground.
