AEV RDS Evo 4.0 – Advanced RDS Encoder with Latest Generation DSP
Overview:
The AEV RDS Evo 4.0 RDS Encoder is equipped with the latest generation DSP, catering to the evolving operational requirements of signal management for FM stations.
Key Features:
- Inputs Section:
- Accepts MPX and RDS signals from external sources.
- RDS Signal Decoder:
- Decodes external RDS signals, allowing for selective data retention or modification before regenerating the RDS data package for transmission to the local FM transmitter.
- Monitors the PI code within the external RDS signal, enabling automatic switching between external and internally generated MPX signals.
- GPO Port:
- Transmits the machine’s input status for easy telemetry interface with transmitters.
- Remote Control:
- Manageable via Ethernet through the internal web server, eliminating the need for PC software installation.
- Web server configurable as CLIENT for LAN network insertion or as SERVER for direct PC connection via Ethernet cable.
- Password protection available to restrict unauthorized access to setup parameters.
