Sielco EXC 300GX
300 Watt FM Transmitter
The EXC 300GX is the 300W exciter from the innovative GT family produced by Sielco.
The Sielco EXC 300GX is appreciated for it’s great efficiency and versatility due to three main reasons: LIGHT weight, MINIMUM size and LOW consumption. To buy an EXC 300GT, as anyone other 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. EXC 300GT is simple to set up: very easy to configure thanks to the intuitive human interface equipped with an elegant LCD graphic display, a multifunction jog control and only a few other control buttons. The high flexibility of this exciter 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 an easier integration with other instruments. The modern and attractive design of our GT transmitters reflects the state-of-the-art technology of this trustworthy model that requires a few maintenance and that allows to spare time and money.
