SielCo EXC5000GX FM Transmitter 5 KW / 5000 Watts

The EXC5000GX is the new 5000W transmitter of the innovative GX version that updates the consolidated transmitters and amplifiers of GT line that has been around for several years and was produced and sold in thousands of units.
With its 33 kg and compact dimensions in 4U (the first in the world), the transmitter is easy to transport and easy to install in any 19″ rack. The new basic amplifier module gives 1200W with LDMOS transistors of the latest generation that has in fact allowed to increase the power while increasing the efficiency that now is close to 70%.
In addition to the beneficial influence on the cost of the electricity, we have less heating generation and therefore greater reliability.
Many options are available on request. The most common are: the internal high quality stereo coder, the AES / EBU digital input, the remote control board via Ethernet allowing remote controlling from anywhere in the world (with devices like PC or mobile devices like smartphone), the remote control via GSM modem and RDS board.
It meets or exceeds CE, FCC or CCIR requirements.

The functions can be extended through the appropriate dedicated options.
