SENSOR – Medium-Power FM Transmitter

SENSOR FM Transmitters combine low energy consumption, exceptional reliability, and advanced connectivity. Their sound is warm and clear, thanks to a high-fidelity design with very low distortion, excellent stereo separation, and a high signal-to-noise ratio.

Composed SYNAPSE Exciter and CELL amplifier, SENSOR is DRM and IBOC ready.

ADVANTAGES OF MODULAR ARCHITECTURE

When the RF amplifier and exciter are integrated into a single enclosure it can complicates maintenance.

The SENSOR modular system overcomes these challenges by making each component independent and self-sufficient, greatly simplifying troubleshooting and fault resolution.

Another key advantage is that both, the FM Exciter and the RF Amplifier, are designed to operate independently and, each of them, includes all necessary components such as power supply, fans, control logic, output filter, and protections. Testing or repairing it, whether on-site or in the lab, requires only a dummy load and an standard power cord, without the need for special tools.

Final test and Burn-In

An extended burn-in procedure is used to thoroughly test the transmitters over many hours of continuous operation, ensuring reliability and reducing the risk of faults caused by early component aging.
