Product Detail

FLD-03-S offers the proven competitive advantages of all-digital processing: operation versatility, instantaneous preset recall, PC control, upgrade capability, consistent high quality, easy installation / configuration.

Typical applications for the FLD-03-S are small and medium radio stations, radio relay stations and advertising splitting systems.

FLD-03-S comes with an user-friendly and reliable PC control software which allows easy operations and a constant monitoring of all processing and modulation parameters.

FLD-03-S processing stage provides for analog stereo audio inputs (a digital input is available as an option). You can choose between two FLD-03-S models, featuring two different Output types: analog stereo or composite MPX (i.e. suitable for a direct transmitter connection or a STL radio link).

FLD-03-S processing is based on 3 compressors related to Bass, Mid and High audio bands. The wide range of preset curves and the sophisticated AGC stage allows all users (even unskilled) to achieve astonishing results for density, richness and colour of the sound.

The digital MPX stereo coder (built-in) makes adjustements easy. The FLD-03-S performance is enhanced by the addition of the Stereo Coder which ensures the best ratio between signal density and modulation level.

Together with the automatic composite clipper (always included), FLD-03-S MPX Stereo Coder ensures a modulation quality much better than that presented by external coders.

The Digital audio input (optional) supports a wide range of numerical formats with several sample rates. Thanks to its automatic recognition of the injected signal and connection type (optic or coaxial), the FLD-03-S digital input doesn’t require any specific configuration.

The Digital RDS coder (optional) provides the services : PS, PI, PTY, M/S, AF, RT, DI, TP, TA. Program service Name (PS) may be broadcast in a sequential mode (up to 8 different words) and with scrolling effect. RDS programming is achieved through the Pc software which comes with the unit.

The Analog Audio Output provides bi-channel (stereo) audio output electronically balanced on XLR male. It provides the L and R processed audio signals on which it is possible to enable/disable pre-emphasis. The level is set via menu.

The FLD-03-S processor comes with Windows software specifically designed for remote monitoring and control of all the processor sections (from the generation of the MPX signal to the level of AGC), as well as message editing and enabling RDS services.
