Questions & answers
Know before you buy
Quick answers about the PRA-AR616, and how it compares.
What is the Bosch PRA-AR616 used for?
The Bosch PRA-AR616 is a 600 W router amplifier designed for PRAESENSA public address and voice alarm systems. It combines audio amplification with integrated routing to distribute sound to selected loudspeaker zones.
How many loudspeaker zones can the PRA-AR616 support?
The PRA-AR616 supports up to 16 zone outputs through its integrated relay-based router. It is a router amplifier, not a 16-channel amplifier with separate amplification for every zone.
Can the PRA-AR616 operate independently of a PRAESENSA system?
The PRA-AR616 is designed for integration into a Bosch PRAESENSA system. Normal audio routing, network control and supervision require the appropriate system configuration.
How does the PRA-AR616 monitor loudspeaker lines?
It supports configurable loudspeaker-line supervision using end-of-line devices or impedance monitoring. The monitoring method can be selected according to the requirements of each zone output.
What happens if the PRA-AR616 develops an amplifier fault?
The PRA-AR616 includes an integrated spare amplifier channel for automatic failover, helping maintain audio distribution if the main amplifier channel fails.
Does the PRA-AR616 support network-based audio and control?
Yes. The PRA-AR616 uses OMNEO IP networking for audio and control within a configured Bosch PRAESENSA system.
Where can I buy the Bosch PRA-AR616 in Pakistan?
Contact ESCO Pakistan to request pricing, check availability and discuss the Bosch PRA-AR616 for your public address or voice alarm project. Product availability and system compatibility should be confirmed before ordering.
