Brand: OMB
Model: EM 5000-DIG
Stands: New
Categories: FM Transmitters
The 5KW FM transmitter, EM 5000 HE DIG PLUS, has been created by the OMB center of development for high efficiency transmitters. It consists on the high efficiency 5KW amplifier, FMA 5000 HE, with 72% efficiency and the EM 25 DIG PLUS, a 25W FM transmitter. The high efficiency 5KW amplifier has an approximate consumption of 6600VA at 230Vac, so it pays for itself in a short period of time due to its low consumption. This 5KW FM transmitter is also available in Dual Drive version
