The Suono Telecom ESVB500 500 Watt FM transmitter is a compact, high-efficiency solution for broadcasters needing reliable main, backup or regional coverage in the 87.5–108 MHz band. This transmitter integrates front-panel control, LAN telemetry and optional IP connectivity in a rugged 3U 19-inch chassis for modern transmitter rooms. Adjustable RF output up to 500 W and wide mains tolerance make the Suono Telecom ESVB500 suitable for new installations and upgrades of existing FM plants that require stable, spectrally clean operation.
The unit supports mono and composite MPX operation with optional internal stereo encoder and RDS modules, allowing straightforward integration with studio processors and STL equipment. High efficiency and a power factor close to 0.95 at 220 VAC help reduce operating costs for regional and community broadcasters. Designed for demanding environments, the Suono Telecom ESVB500 operates across a wide temperature range and at high altitudes, making it appropriate for remote and mountain-top locations.
The ESVB500 provides continuously adjustable RF output from 0 to 500 W with fine (1 W) and coarse (10 W) steps set from the front-panel encoder and display. It covers 87.5–108 MHz as standard, with variants for OIRT and Japanese bands, and delivers power into a 50 Ω N-type RF connector. Integrated low-pass and band-defining filters maintain good spectral purity so the transmitter meets strict FM broadcast mask requirements in crowded bands.
To protect the RF stages, the Suono Telecom ESVB500 uses automatic VSWR fold-back that maintains safe operation into mismatched loads. A high-stability internal TCXO reference provides tight frequency accuracy across the operating range, keeping the carrier on channel. Forward and reflected power, temperature and alarms are monitored from the front panel and, with optional LAN or serial modules, from remote control systems and NOC environments.
The audio section supports balanced analog left/right, unbalanced composite MPX, AES/EBU digital audio, SCA and RDS inputs, so the transmitter can be deployed in mono or stereo/MPX chains without extra converters. Mono mode offers selectable input impedance with precise level adjustment and flat response from 30 Hz to 15 kHz, while composite operation provides wideband flatness to 100 kHz with low distortion suitable for modern FM processing chains. Typical applications include regional and local FM coverage, community and commercial stations, and N+1 systems where multiple units share redundant antenna infrastructure.
