Keenfinity Expands PRAESENSA Line With New Router Amplifier for Voice Alarm Projects
Keenfinity Group has introduced the PRA-AR616 router amplifier for its PRAESENSA platform, targeting voice evacuation and essential-zone applications where integrators need to balance compliance, reliability, and cost efficiency
Keenfinity Group has unveiled the PRA-AR616 router amplifier, a new addition to its PRAESENSA public address and voice alarm portfolio, designed to expand the system’s use in essential-zone applications. According to the company, the launch is intended to help system designers tailor performance more precisely by matching amplifier capabilities to the actual needs of each zone instead of over-specifying the entire installation.
As reported by Keenfinity Group, the new unit features a single 600-watt amplifier channel routed across 16 outputs and includes a built-in spare channel for full system redundancy while meeting EN certification requirements. The company said this makes the product suitable for environments where emergency voice evacuation, announcements, and basic background music are the main priorities, including offices, schools, small airports, shopping centers, and museums.
The launch reflects a practical trend in the life-safety segment, where consultants and integrators are increasingly looking for more flexible and cost-conscious ways to design compliant public address and voice alarm systems. Keenfinity said the PRA-AR616 is designed to support that need by allowing essential zones, such as staircases and hallways, to be equipped differently from performance zones that require higher-quality music and more advanced audio processing.
The company added that the amplifier is based on PRAESENSA’s IP architecture and offers line supervision on all outputs, 70 V compatibility, and low energy consumption. In market terms, the new product could appeal to projects seeking a stronger balance between scalability, resilience, and budget control, particularly in mid-sized facilities and larger sites where mixed-zone design is becoming more common.
