Can be bridged into:
- 1 x 160 W + 6 x 80 W
- 2 x 160 W + 4 x 80 W
- 3 x 160 W + 2 x 80 W
- 4 x 160 W
The amplifier has 48 VDC input which allows to connect with battery backup system for maximum availability and durability in an voice evacuation system, and has been developed to meet the specific requirements of the EN 54-16 standard for safety installations.
The amplifier is 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 amplifier is 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.
