LD1.2
Description
The Opus Technologies LD1.2 is next-generation low-loss magnetic loop amplifiers witch incorporates two independent amplifiers out of phase.
%It provide an output current of 2x5Arms as well as a AGC to ensure optimum audio quality. The amplifier incorporate a fault synthesis that controls contiuously 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 tow 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 LD1.2 proven technologiy and quality of manufacturing allow us to offer a 5 years warranty.
