Suono Telecom ESVA50 50 Watt FM Transmitter is designed for community, campus, religious and commercial stations that require dependable 50 Watt RF power in a compact 1U enclosure. Suono Telecom ESVA50 covers the full 87.5–108 MHz band without manual tuning, making it ideal as a main transmitter for local coverage, as an exciter feeding a larger PA stage, or as a ready-to-use standby in critical on-air chains. The reduced dimensions and weight simplify integration into existing racks and small transmitter huts.
The ESVA platform uses a high-quality FM signal generator with excellent signal-to-noise ratio and ultra-low THD, ensuring top sound quality on air. RF output from Suono Telecom ESVA50 is continuously adjustable from 0 to 50 W into 50 Ω via an N-female connector, with synthesizer steps of 10 kHz, tight frequency stability and very low spurious and harmonic emissions for regulatory compliance. The baseband path offers 30 Hz–60 kHz response within 0.15 dB, with unweighted S/N ratio better than 80 dB and distortion typically 0.06% at 1 kHz, while selectable 50 or 75 µs pre-emphasis supports different regional standards. MPX and three SCA inputs on BNC connectors allow straightforward connection of external stereo encoders, RDS generators and audio processors.
To keep your station on air under fault conditions, the Suono Telecom ESVA50 transmitter incorporates dynamic protection that automatically reduces output power in case of high VSWR or overload rather than shutting down abruptly. A wide-range 100–240 VAC, 47–63 Hz power supply supports global deployment and rough mains environments, and forced-air cooling with a brushless fan maintains reliable operation from −10 to +45 °C at up to 90% humidity. Front-panel controls and indicators make it easy to set frequency under password protection, adjust power and check operating status, while the 1U professional case with low power consumption and lower heating is well suited to dense racks and cost-sensitive installations.
For broadcasters looking for a robust, compact 50 Watt FM solution, Suono Telecom ESVA50 provides an effective balance of broadband flexibility, high audio performance and intelligent protection. If you are comparing equivalent 50 W transmitters from other manufacturers, you might also consider the EUROTEL ETL50, the OMB EM 50 DDS or the DB Mozart Next 50, each offering its own feature set and integration options.
