Bosch PRS-16MCI Multi-Channel Interface

Bosch PRS-16MCI Multi-Channel Interface

The Bosch PRS-16MCI is a professional multi-channel interface module designed for the Praesideo digital public address and emergency sound system. It acts as a bridge between the Praesideo network and basic power amplifiers that do not have direct network connectivity.

The unit enables reliable audio distribution, amplifier control, and full system supervision, making it ideal for mission-critical PA/VA (Public Address / Voice Alarm) installations such as airports, industrial facilities, and large public buildings.

Key Features

• Interface for Praesideo basic amplifiers
• Up to 16 configurable audio channels (14 main + 2 spare)

• 32 control inputs and 16 control outputs
• Automatic amplifier supervision and fault detection
• Automatic switching to backup amplifier in case of failure
• Fail-safe audio loop-through for emergency signals
• Configuration via Praesideo system software
