Bosch Praesideo Digital Public Address & Voice Alarm - Amplifiers Basic

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 equalisers, delay and AVC are required. They do not have a Praesideo network connection. Instead, these amplifiers are connected to the Praesideo network via the P004238N multichannel interface, which provides the basic amplifier with audio signals and has full control. There are two versions, the P004239N (1x 500W), and the P004240N (2x 250W).

The basic amplifiers are completely supervised and fault events are reported via the multichannel 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.
