The Sielco RFB 5000GX model is the 5000W amplifier of the innovative GX family produced by Sielco. It is appreciated for the great efficiency and versatility due to three main reasons: LIGHT weight, MINIMUM size and LOW consumption. To buy an RFB 5000GX, as anyone another model of the GT line, means to make a winning choice, to enjoy all the relevant advantages during all the life of the product and to spare money: less transport costs, less needed space to install it and the lowest energy consumption during the work. RFB 5000GX is simple to set up: very easy to configure thanks to the intuitive human interface equipped with an elegant LCD graphic display, multifunction jog control and only a few other control buttons. The high flexibility of this amplifier could be even increased through the use of important options like telemetry/remote control systems, Ethernet connection with SNMP protocol, high-quality stereo encoder, audio digital board in accordance with AES/EBU directive and RS232/485 serial port to enable easier integration with other instruments. The modern and attractive design of our GX transmitters reflects the state-of-the-art technology of this trustworthy model that requires a little maintenance and that allows sparing time and money. N.B.: the amplifier characterized by the code RFB needs an exciter like our EXC30GT as a driver.
