In the context of safety and critical communication, the COMPACT and OPTIMAX3 series public address and voice alarm control systems are based on a modular matrix architecture with IP connection, allowing for full customization through the use of expansion cards. Within this UMX series card range, audio output management is a core component where each model meets a specific installation need, whether using the COMPACT system matrix or the UMX-03 matrix specific to the OPTIMAX3 system. The base card is the UMX-2SA, providing two audio outputs with volume control, a ten-band equalizer, and all the monitoring functions required for regulatory compliance.

For projects where service continuity is the decisive factor, as is specifically the case with the OPTIMAX3 system, we offer the UMX-SYL card, which provides extra security by incorporating audio redundancy to guarantee operational continuity. The latest addition is the UMX-SLR card, which maintains the same control and monitoring features as the standard UMX-2SA model but integrates an essential technical functionality for certain environments: delay management. This capability allows for precise adjustment of the audio signal emission time, a vital tool for inline speaker distributions and acoustically complex environments.
The application of this delay with the UMX-SLR is particularly critical in locations such as tunnels, where the physics of the space and the sequential distribution of speakers create acoustic phenomena that can drastically degrade message intelligibility. By electronically compensating for the distance between emission points, the UMX-SLR ensures that sound waves reach the listener coherently, preventing cacophony and ensuring that, in an emergency, voice instructions are clearly understood. With this new addition, OPTIMUS modular matrices reinforce their versatility, offering a precise technical solution for every acoustic engineering challenge, whether seeking total redundancy or maximum sound clarity in harsh environments.
