ECRESO ­FM 3kW
Adds greater redundancy to compact transmitter range

Overview

The compact Ecreso FM transmitter range includes a direct to channel digital modulator into its 2U or 3U chassis and offers a wide range of on-board features in addition to its core structure of digital modulator, 6th generation MOSFET and up to 76% efficiency. These include a dynamic RDS encoder, stereo encoder, 5-band sound processor, MPX over AES, and GPIO support as well as Single Frequency Networking.  With the launch of the Ecreso FM 3kW Transmitter, the power range of the compact system is extended to now reach from 100W up to 3kW.

However, the new Ecreso 3kW FM does not only add additional power but also built-in redundancy on the system’s power supplies, power amplifiers and fans as well as hot-swappable power supplies.

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.
