Opus Technologies LD3.2
The Opus Technologies LD3.2 is next-generation, low-loss magnetic loop amplifier. This device incorporates two independent amplifiers out of phase.
They provide an output current of 2X10Arms, as well as a AGC to ensure optimum audio quality. The amplifier incorporates a fault synthesis that controls continuously the loop and the amplifier. The information is displayed on the front panel and can be deported thanks to a dry contact.
It can equip adjoining rooms (amphitheater, courtroom, etc) with two magnetic loops installed hairpin. This type of installation makes it possible to limit the external radiation of the magnetic field, to guarantee uniformity of coverage and to provide a power which makes it possible to limit the distortions due to the presence of metal.
The LD3.2 proven technology and quality of manufacturing allow us to offer a 5 years warranty.
