SielCo EXC2000GX FM Transmitter 2 KW / 2000 Watt

The EXC2000GX is Sielco’s 2 kW model. The EXC2000GX is also convenient during installation: it works in an instant and is easy to set up using an intuitive operating interface common to all GT models, equipped with a common graphic LCD screen, a practical multifunction button, and several other keys.

This basic digital version can even be expanded with other important options such as telemetry/remote control via GSM cellular networks, the Ethernet cable with SNPM protocol, the high-quality stereo encoder, the digital audio input compliant with the AES/EBU directive, and the RS232/485 serial remote control ports that enable normal integration with other machines in a system. The modern and relevant design of GX transmitters incorporates a modular design philosophy aimed at reducing the number of maintenance interventions and lowering relevant costs. All of this is complemented by contact with the sales department, which has the utmost confidence in the sales process.
