ETG 3500, the smallest and lightest 3,5KW FM Stereo Transmitter of the world housed in 4 units rack only and 35 Kg including ,AES-EBU digital input, a complete high quality Stereo Exciter and a 3.5KW amplifier.
ETG 3500 is the result of an unprecedent design commitment, aimed at the study an adoption of innovative technical solutions which will mark an important turning point in the FM world.
ETG 3500 uses another exclusive ELENOS patented design: The polygonal coupling of 12 power modules in a single jump and the ICEFET technology, increase the overall efficiency with a great reduction of heat dissipation.
