Stereo/RDS Coder module
For support of FM Stereo modulation an optional Stereo/RDS Coder module can be installed. The Coder
accepts analog signals from the external audio input rear connectors or generated by the RF-Board LF
Generator. Alternatively, digital S/P DIF audio signals can be supplied to the S/P DIF connector on the
rear panel.
The coder digitally performs the signal processing and generation of ARI/RDS signals. The coder output
provides the analog multiplex signal that is fed into the RF-Board modulation matrix.
For power supply and digital control the Coder module is connected to the Basis Board by a ribbon cable.
