The basic amplifiers are cost effective alternatives to the regular Praesideo power amplifiers, for situations where no built-in digital signal processing functions, such as equalizers, delay and AVC are required. They do not have a Praesideo network connection. Instead, these amplifiers are connected to the Praesideo network via the PRS-16MCI Multi Channel Interface, which provides the basic amplifier with audio signals and has full control. There are two versions, the PRS-1B500 (1 x 500 W), and the PRS-2B250 (2 x 250 W).

The basic amplifiers are completely supervised and fault events are reported via the multi channel interface (IEC 60849 compliant) to the Praesideo network controller. The basic amplifiers provide connections for separate group A and group B loudspeakers for each zone, and support class-A loudspeaker loop wiring. The units should be mounted in a 19"-rack with the included mounting brackets.
