Sielco PolyEco 1000 watt Digital DDS FM Transmitter.


Sielco PolyEco 1000 Digital DDS Exiter 1 KWatt is a digital exciter of the innovative POLYHEDRA family, produced by Sielco. It is appreciated for the high efficiency and versatility due to three main reasons: LIGHT weight, MINIMUM size and LOW consumption. The SIELCO DIGITAL FM MODULATOR is a new digital FM modulator / exciter offering RF output power adjustment up 1Kw over the complete FM band (87,5 ~ 108.00Mhz).
The system is designed according to all the latest digital technologies with modern digital components, FPGA and DSP.
The equipment is supplied with a complete analog and digital audio interface including audio IP.
With 10 kg and compact dimensions in 2U, the transmitter is easy to transport and easy to install in any 19" rack. Many options are available on request
