Intelligent design delivers 1+1 levels of performance

The latest and most powerful system in our range, the ECRESO FM 5kW/10kW transmitter offers a truly revolutionary approach to high power FM transmission.

With all the key advantages of the core ECRESO range, the ECRESO FM 5kW/10kW adds a whole new dimension of reliability, redundancy and efficiency.  The power amplifiers, power supplies and even the fan modules are fully hot swappable and redundant and a completely passive 6-way coupler ensures that, should one of the amplifiers suffer a fault, the transmitter can stay on-air with minimum power loss indefinitely until the fault is rectified.


The highly efficient, self-monitoring power supplies contribute to a transmitter system efficiency of up to 76%, the highest available in today’s FM broadcast market. 

The unique architecture and innovative design ensure ease of access, ease of use and ease of maintenance.
