Combining the very latest technologies with ECRESO’s proven RF experience, our 750W FM Transmitter has been designed to offer an innovative and highly reliable solution for medium power transmission.
Based on a 6th Generation MOSFET, the Ecreso FM 750W is highly robust and delivers efficiency of up to 70%. Top signal quality and performance are achieved thanks to the “FM Band Direct to Frequency” Digital Modulator. It also offers several innovative features such as dynamic RDS encoding and an FM Limiter.
Fully featured for local maintenance and configuration, the Ecreso FM 750W allows extensive remote control by Web server, SNMP, RS232 or GPIOs.
WorldCast Systems offers a standard warranty of 3 years on all our FM transmitters and up to TEN YEARS' Warranty on our range of compact FM transmitters and new ECRESO FM 5kW/10kW for a small additional charge.
No other FM Transmitter Manufacturer even comes close to that commitment or confidence! We can offer the 10 Year Warranty with confidence thanks to:
EMR is a proactive service available on ECRESO FM Transmitters. It sends the user regular reports on the status of key parameters such as temperatures, currents and voltages, plus information on the performance and lifespan of components such as the fan and power supply of the transmitter.
With detailed logging and trend analysis, Expert Maintenance Reporting can identify slow-burning problems and issue warnings well in advance to allow for corrective action to be taken. A map-based display of current statuses and detailed, user-friendly reports and graphs can be accessed around the clock in the EMR user page.
The WorldCast MANAGER Desktop simplifies the management of all SNMP-enabled devices in a network, providing real-time status and visualization of multiple devices from a single screen. The intuitive and simple-to-use interface shows all devices located at your site(s) displaying product information, alerting you to any alarms and providing one-click access to the unit’s web-based control interface.
Free to download, the WorldCast MANAGER Desktop is compatible with all WorldCast Systems’ equipment as well as SNMP devices from ANY manufacturer.
The WorldCast MANAGER Server adds recorded measurements, detailed logs, alarm management / notifications and more…
«The compact design of the ECRESO is not only a neat solution, it also makes it really easy to conduct maintenance tasks with no nasty surprises! They have totally changed our way of operating – very much for the better!»
Sylvain Cavet, Technical Director, Broadcast-associés, France
«We have a 10 year warranty on the Ecreso system, a sign of a manufacturer with confidence in their design and one of these things that helps me sleep a little easier.»
