Designed for reliability and longevity, the modular design of the Ecreso FM 3500W Transmitter 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 3800W, it provides a comfortable margin over nominal power.
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.
The Ecreso FM Transmitter range also features an integrated multi-band sound processor! This fully digital sound processor offers the highest signal quality and outstanding reliability as no additional hardware is required*.
You can choose from a wide-band or a multi-band version to achieve the level of processing required at your site and the processor is supplied with a full set of presets for many different formats and requirements.
Sound Processor interface
Automatic Gain Control
The first stage of the processor is an automatic gain control which regulates the perceived volume level of the station output across all audio sources and formats. It uses predictive algorithms and protects against unwelcome increases in noise.
Equalization, Bass and Treble Enhancers
The AGC is followed by enhancers which embellish both the low and high frequencies. Combined with 3 parametric equalizers, they enable the creation of a distinct sonic signature.
Stereo Enhancer and Limiter
A stereo enhancer can be used to improve the stereo image of your station when using non-mono content. It also includes a stereo limiter to improve the quality of your station in areas with problematic coverage.
5 Band Processor
The 5 Band Processor dynamically adjusts the gain of each audio band. Depending on the selected preset, it can work as a slow and purist multi-band leveler, or as a fuller processor to create a strong sonic signature. The fidelity parameter enables you to fine tune the bands according to your preference; from a purist sound to a more colored texture.
5 band Limiters
5 limiters have been designed to facilitate the work of the final clipper. For soft formats, the limiters provide smooth protection for your final audio and for commercial stations, they can be used to create extra loudness.
This section uses several limiters including HF and final low distortion limiters. In addition, and independently of any preset, the ECRESO FM Transmitter can be configured with an MPX Power Limiter and a deviation Hard Clipper for transmitter protection.
* Check your version for compatibility
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 simplifies the management of all SNMP-enabled devices in a network, providing real-time status, historical data 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.
The WorldCast Manager is compatible with all WorldCast Systems’ equipment as well as SNMP devices from ANY manufacturer.
"The efficiency, remote monitoring capability and reliability that the ECRESO units could offer at a relatively attractive price level meant that they were undoubtedly the best, overall supplier."
