Strengthening broadcast network security with the first FM transmitter featuring APTmpX

As cyberattacks continue to make headlines across industries worldwide, securing broadcast infrastructure is no longer optional — it is essential. With the release of version 3.4.0, the AiO Series takes a decisive step forward, combining advanced network security with major enhancements to its integrated IP codec and audio capabilities, making it the first FM transmitter in the world to natively embed APTmpX technology.

Security is now at the core of your transmission chain. Version 3.4.0 introduces LDAP authentication, enabling seamless integration with centralized IT environments and strengthening access control policies across your organization. Combined with SYSLOG support, your transmitter can now send events directly to centralized monitoring systems, ensuring full traceability and faster incident response. Enhanced logging gives IT teams the tools they need to monitor, audit, and protect critical broadcast infrastructure. In a context where network intrusions, and infrastructure attacks are increasing, these improvements significantly reinforce the resilience of your broadcast network.

At the same time, the integrated APT IP Decoder reaches a new level of performance. With the implementation of APTmpX V2, the AiO Series now supports MPX compression with RDS at 300, 400, and 600 kbps, enabling precise adaptation to various network conditions. This evolution improves bandwidth optimization while enhancing robustness and operational flexibility. By embedding APTmpX directly inside the transmitter, broadcasters benefit from a simplified architecture, fewer external devices, and stronger end-to-end reliability.

Version 3.4.0 also enhances the built-in Icecast and Shoutcast player, widely used by radio stations across the world. The player now supports both MP3 and AAC formats, providing greater flexibility, quality and compatibility with common streaming infrastructures. This improvement allows broadcasters to use web streams as a reliable backup source while maintaining optimal audio performance.
