The Suono Telecom DSS300 Digital Stereo Encoder, also known as the DSS300 Symphony One, is a stand-alone FM stereocoder designed to generate a precise MPX composite signal for professional broadcast chains. Built around DSP processing, the Suono Telecom DSS300 Digital Stereo Encoder combines stereo generation, pre-emphasis and controlled clipping in a single 1U unit, simplifying integration with existing audio processors and transmitters. Its design targets broadcasters who need stable, predictable multiplex performance with minimal adjustment and consistent sound across a network of FM transmitters.
The DSS300 digital stereo encoder provides left/right stereo separation greater than 75 dB, with typical values approaching 80 dB, ensuring clean imaging and accurate stereo soundstage for listeners. Mono-to-stereo separation is specified above 80 dB, while low total harmonic distortion figures keep the composite signal extremely clean. A 15 kHz low-pass filter and carefully managed pilot and subcarrier levels help protect against over-deviation and adjacent-channel interference when the multiplex feeds the FM exciter.
Suono Telecom DSS300 Digital Stereo Encoder accepts both analog balanced audio inputs and AES/EBU digital audio, giving engineers freedom to connect directly to modern digital studios or legacy analog consoles. Adjustable output level with low output impedance allows the DSS300 to drive a wide range of exciters, STL links and processing equipment without level-matching issues. Typical applications include upgrading existing FM transmitters with a modern digital stereocoder, pairing the DSS300 with external audio processors for music-intensive formats, and standardising multiplex quality across multi-site networks.
Broadcasters comparing options in this class may also consider other FM stereo encoders listed in generic FM stereo encoder ranges, which include different DSP architectures and feature sets for various budgets.
For projects needing integrated audio processing plus stereo coding in a single box, alternative products such as combined audio processor and stereocoder units can reduce rack space and simplify configuration while targeting similar composite performance.
Engineers planning larger audio-processing chains and multiplex upgrades can review the wider audio processors category to match the Suono Telecom DSS300 with companion processors or to evaluate alternative processing-plus-stereo solutions.
