Station Audio Control 22 - SAC - 4 Channels I/O, SNMP

AeroAudio SAC – Station Audio Control

The AeroAudio SAC monitors the performance of public address amplifiers and loudspeaker networks, helping identify faults before they affect service. Designed for railway stations and other PA installations, it checks audio levels and loudspeaker impedance against calibrated reference values, reporting deviations through network alerts and logs.

Supporting up to four speaker circuits, the SAC works with both low-impedance and 100 V loudspeaker systems. Automatic, scheduled testing checks speaker network integrity without audible interruption, while audio monitoring helps confirm that amplifiers are operating during announcements.

A front-panel display and HTML5 web interface provide access to system status and configuration. SNMP alerts support integration with central monitoring systems, and NTP synchronisation keeps event logs aligned across devices.
