Suono Telecom ESVA250 is a high-performance 250 Watt FM broadcast transmitter designed for community, regional and commercial stations that need dependable RF power in a compact 2U chassis. Suono Telecom ESVA250 covers the full 87.5–108 MHz band without manual tuning, making it suitable as a main transmitter for local coverage, as an exciter driving higher-power amplifiers, or as a ready standby unit in critical on-air chains. The robust solid-state MOSFET design and modest footprint of Suono Telecom ESVA250 help simplify installation in crowded racks and transmitter rooms.
Within the ESVA platform, the Suono Telecom ESVA250 transmitter provides continuously adjustable RF output from 0 to 250 W (with a typical maximum around 270 W) into 50 Ω through an N-type connector, using FM modulation with F3E emission class and a broadband VCO/synthesizer architecture. The standard frequency range is 87.5–108 MHz, with optional 76–88 MHz versions, and spurious emissions are typically below −80 dB with harmonics better than −65 dB to meet regulatory requirements. The audio/baseband path in Suono Telecom ESVA250 offers wide 30 Hz–60 kHz response within tight tolerance, very low THD and FM signal-to-noise ratio better than 80 dB, while selectable 50 or 75 µs pre-emphasis supports different regional standards.
Audio and MPX connectivity includes balanced mono inputs for L+R audio and a composite MPX input on BNC, plus SCA/RDS inputs for subcarriers, allowing Suono Telecom ESVA250 to integrate cleanly with external audio processors, stereo encoders and RDS generators. Automatic fold-back protection reduces power in the event of high VSWR or overload, helping to keep the transmitter on air and protect the PA stage. A wide-range mains supply, low power consumption and forced-air cooling with a brushless fan support reliable operation across typical broadcast temperature and humidity ranges, while the 2U rackmount form factor and front-panel metering make Suono Telecom ESVA250 straightforward to install and maintain.
For broadcasters seeking a compact yet robust 250 Watt FM solution, Suono Telecom ESVA250 offers an attractive balance of broadband flexibility, strong audio performance and efficient power use. If you are comparing equivalent 250 W transmitters, you can also consider the EUROTEL ETL1250, the OMB EM 250 DIG PLUS and the Suono Telecom ESVB250, each providing its own feature set and integration options.
