FM Broadcast Amplifier Mirage 680

Description

The FM amplifier MIRAGE 680 series is designed to simplify transport and installation. The design redundancy (a power supply for every MOS device), the oversized unbalanced power dummy loads, the wide input range of the switching-mode power supplies, allow a NO STOP transmission 24h per day. The temperature of the amplifiers is guaranteed by an extremely noiseless forced air cooling system. A microprocessor monitors and controls the currents of the MOSFETs and voltages of the power supplies together with the measure of DIR / REF power and the temperature of the heat-sink. A large multifunction display makes it possible to verify all the operating parameters ofthe unit.
