PRS-2P250-EU
Bosch PRS‑2P250 Power Amplifier 2 x 250 W, 2-channel power amplifier with Praesideo network, connection, rack unit 2 RU, Frequency response : 60 Hz to 19 kHz (-3 dB), Rated load resistance 40 ohm (100 V); 20 ohm (70 V), 10 ohm (50 V) Loudspeaker output.
The PRS-2P250 Power Amplifier receives input signals over the network. They have two auxiliary audio inputs for local audio, and eight control inputs which are easily programmable for actions, and priorities can also be assigned to these inputs. That control input is capable of controlling open and short circuits on the attached panel. Control outputs are freely programmable for faults and call-related actions.
The units are self-monitoring and continually report their status to the network controller. They support both single branch and redundant loop cabling. The amplifiers have a changeover facility for spare power amplifier switching. Changeover relays are included with the units. The amplifiers have a 48 V DC back-up supply input.
The digital audio processing can handle three parametric equalization sections and two shelving equalization sections per channel with configurable audio delay.
