Manufacturer: Bosch

Product Overview

The Bosch PRS-4B125-EU is a cost-effective 4-channel basic power amplifier. It delivers 125W per channel. Furthermore, it is designed for integration with the Praesideo digital public address and emergency sound system. Housed in a 19-inch rack unit, it suits venues without built-in DSP needs. Instead, it connects via the PRS-16MCI Multi Channel Interface. Thus, it handles audio, control, and fault supervision. Additionally, it runs on mains power and a 48 VDC backup battery with automatic switchover.

Key Features and Benefits

• High-Efficiency 4-Channel Amplification: It supplies four channels at 125W each. Moreover, it features built-in transformers for 70V and 100V lines.

• Praesideo System Integration: It links to the Praesideo network through the PRS-16MCI interface. Consequently, it achieves IEC 60849 compliant supervision.

• Dual Power Operation: It runs on standard AC mains or 48 VDC backup power. Therefore, switchover happens automatically during emergencies.

• Flexible Zone Routing: It includes separate group A and group B terminals. Furthermore, these support class-A loop wiring and spare channel setups.

• Local Audio Inputs: Each channel features symmetrical analog inputs. Additionally, rear rotary volume controls manage low-priority local audio.
