Power amplifiers

We offer class-D transformer isolated power amplifiers for 50 V and 100 V distributed loudspeaker systems. They are designed for rack mounting, 2U each.

In a bridged mode, amplifier channels are combined and the effect is increased.

The amplifiers have 48 VDC inputs, allowing connection to battery back-up systems for maximum availability and durability. They are powered from external power supply module ABT-PS48800 working in a block. The current from the 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).
