The smartRX is a smart FM receiver for use in relay transmission (retransmitter) sites. It is ideal for locations where the source signal may be lower than +54dBuV/m and where there are strong interfering signals.
It incorporates a sophisticated RF input filter, followed by a high-sensitivity front-end with quad Varactor filtering, which provides excellent immunity to other signals and high selectivity. The IF stage features triple filtering and DSP stages that reconstruct the baseband without the noise associated with weak incoming signals. All stages of the multiplexed signal are re-generated without noise, including the pilot signal, the stereo subcarrier and the RDS subcarrier.
This not only provides the optimum audio quality for the retransmitted signal, but also ensures that the levels are brought back into compliance with broadcasting regulations, especially spectral occupancy.
All adjustments are made automatically by the DSP circuitry, making installation a very simple process. In addition, the multiplex output level can be adjusted via the panel’s LCD menu.
