Summary: PolyEco is the innovative family of high-end digital  
FM transmitters of Sielco. They are especially suited as high  
performance power system exciters or compact low-mid power  
transmitters. The same cabinet may in fact be fitted with 50,  
100, 300, 500, 1000W power stage (PolyEco50, 100, 300, 500,  
1000).  
  
All features can be controlled via the large touch-screen display  
4.3" or remotely. Many advanced features are inside by default  
in the basic version such as: stereo and RDS encoder, audio  
change-over, remote-control via LAN and SNMP, "FFT" spectral  
analysis of the audio sources, SFN synchronization and much more.  
  
Desc: The FM transmitter uses a weak set of default administrative  
credentials that can be easily guessed in remote password attacks  
and gain full control of the system.
