Stereo encoders

Stereo encoders ensure stereo sound with good channel separation and are sometimes also equipped with RDS and DSP audio processing. Good encoders such as our SE8000 DSP+ have built-in compressor, limiter, balanced inputs, sharp 19KHz stereo carrier notch filter, pre-emphasis, LC input filters and ESD protected inputs which all help to bring out the best sound. We also carry dedicated audio processors with built-in stereo encoders, designed for FM radio stations.
