Overview

Combining the very latest technologies with ECRESO’s proven RF experience, our 1500W 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 1500W is highly robust and delivers efficiency of up to 72%. 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 5 band sound processing.

Fully featured for local maintenance and configuration, the Ecreso FM 1500W allows extensive remote control by Web server, SNMP, RS232 or GPIOs.

Processing stages

Audio Processor on Ecreso Transmitter. Processing stages

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. 

Final Limiters
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.
