Designed for reliability and longevity, the modular design of the Ecreso FM 5000W is based on the ECRESO FM 1500W/2000W Amplifier module.

This amplifier delivers the best cost/watt ratio over the lifetime of the transmitter, has the lowest heat dissipation available on the market today and, with a maximum output power of 5500W, it provides a comfortable margin over nominal power. The amplifier redundancy ensures that, even if you lose one amplifier module, you still have more than 2500W on air.

A crystal-clear signal is achieved using the ECRESO FM 100W exciter and its direct to channel digital modulator and the system can be fully controlled and monitored through the built-in Web interface and SNMP protocol.

Be Proactive with Expert Maintenance Reporting

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.
