BOSCH PRS-2P250 Presadio Controller
SKU:235,000৳
The Power Amplifiers receive input signals over the network. They also have two auxiliary audio inputs (four for LBB 4428/00) for local audio. Their eight control inputs are freely programmable for system actions, and priorities can be assigned to these inputs. Each control input has the ability to monitor the attached line for open and short-circuits. Control outputs are freely programmable for faults and call-related actions.
The 2 x 16‑character display and the rotary control enable local status inquiries. The display shows the VU‑meter reading when the audio monitoring mode is active. Audio can be monitored by headphones. 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.
