Overview

Combining the very latest technologies with ECRESO’s proven RF experience, our ECRESO FM 1000W - Limited to 750W 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 dynamicRDS encoding and 5 band sound processing.

Fully featured for local maintenance and configuration, the Ecreso FM 750W allows extensive remote control by Web server, SNMP, RS232 or GPIOs.

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.
