Praesideo PRS-xBxxx Basic Amplifiers
 
Features:
 

- High efficiency class-D amplifier channel(s)
- Switched mode power supply
- Local audio inputs
- Mains and battery operation
- Complete supervision

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 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). For more information download the Datasheet below...

Praesideo LBB 442x/xx Power Amplifiers
 
Features:
 

- 1, 2, 4, or 8 audio outputs (selection from 100 / 70 / 50 V outputs)
- Audio processing and delay for each amplifier channel
- Amplifier supervision and spare amplifier switching
- Loudspeaker line & loudspeaker supervision (LBB 4428/00 only line supervision)
- Eight control inputs and 1, 2, 4 or 8 control outputs

There are four types of power amplifier units in the Praesideo product range. These differ in the number of amplifier channels per frame: one, two, four, or eight. The overall power rating is 500 watts for all of the amplifiers. The power amplifiers can be set to 100 V, 70 V and 50 V output tappings. They have short-to-ground and shortcircuit detection functions, and can generate their own pilot tone for supervision purposes. For more information download the Datasheet below...
