Description
SielCo EXC FM Transmitter 300 Watts
The EXC300GX is the 300W rated model of the innovative GX Transmitter family appreciated for their great efficiency and versatility, due to 3 intrinsic factors: decreased weight, minimal size and reduced consumptions. As per all the GT devices, deciding to buy a EXC300GX represents a winning choice because it allows to obtain remarkable benefits for all the product life. Once bought, it ensures savings on the transport costs and rent burdens of the station where it is installed only for its small size and weight. Even more important, also during its normal job it pays back day by day, thanks to the lowest electrical costs of its class which minimize the electric bill.
The Sielco EXC300GX is convenient also at the moment of the installation: it is operative in a blink and it is easy to set up thanks to an intuitive control interface – common to all GX models – equipped of a detailed LCD graphic display, a multifunction practical knob and few other buttons. This remarkable basic flexibility can be even increased by other important options, as the Telemetry / Remote Control System possible through GSM cellular networks, the Ethernet connectivity with SNMP protocol, the high quality Stereo Encoder, the Digital Audio input conforming to the AES/EBU directive and the RS232/485 Serial Remote Control ports which enable an easier integration with other machines in a system.
The modern and attractive shape of GX transmitters reflects the trustable modular project philosophy aimed to reduce the number of maintenance interventions and make them easier to minimize the relevant costs. All that is completed by an efficient Sielco post-sale service, ensuring the best trust for the final user. For all the product life.
