4-channel public address and voice alarm system IF-8P4ETH

IPbattery backed

The IF-8P4ETH combines IP network control and integrated power amplification in a single unit, designed for OPTIMAX3 installations where space, redundancy and system supervision are critical, such as railway stations, tunnels, industrial complexes and large public infrastructures.

The unit hosts up to 4 high-efficiency amplifiers (>90%) with configurable output ratings of 120, 150, 250, 300 or 460 W per channel, with the option to reserve one channel for backup operation. Amplifier hot swapping allows replacement without interrupting system service, while A/B speaker line supervision ensures compliance with voice alarm requirements. The unit also provides direct interface with fire alarm systems (FAS).

The IF-8P4ETH supports 4 simultaneous IP audio channels, includes analogue audio inputs for integration with existing systems, receives SIP call messages and offers 16 GB of internal storage for pre-recorded audio. When higher power output is required, additional expansion units can be added without modifying the base configuration of the network.

Manufactured in-house by OPTIMUS with more than 30 years of experience in mission-critical PA and voice alarm projects, the IF-8P4ETH benefits from full control over hardware and software design, enabling custom adaptations when project specifications require them.
