The 25 / 50 W and 100 W amplifiers have a compact design and serve to amplify the power of the bass signals in the DS-6 systems from Neumann Elektronik. The amplifiers provide connectivity to all voice communication centers with an analog interface.


Due to the different operating voltages, they can be used according to the customer's wishes. They are also used for public address and emergency alarms in small areas and fire-prone zones, in office buildings, storage halls and sites, production areas, construction and production sites.
