Description

The Bosch PRS-2B250-EU 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 four versions, the PRS‑1B500 (1 x 500 W), PRS‑2B250 (2 x 250 W), PRS‑4B125 (4 x 125 W) and the PRS‑8B060 (8 x 60 W).

The Bosch PRS-2B250-EU basic amplifiers are completely supervised and fault events are reported via the multi channel interface 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.

The PRS‑1B500 is a single channel, 500 W unit, the PRS‑2B250 is a two-channel amplifier with 250 W per channel, the PRS‑4B125 is a four‑channel amplifier with 125 W per channel and the PRS‑8B060 is an eight‑channel amplifier with 60 W per channel. The power supply is switched mode with low inrush current and the units can run on 48 V, battery stand-by power.
