Monacor LA-402 PA loop amplifier

Active loop amplifier
Dynamic compressor for setting up an inductive sound system in large rooms up to 750 m2.
Inductive audio transmission allows users to receive audio signals from hearing aids with a "telephone coil" or inductive receivers such as the LR-202. One advantage of inductive sound systems is wireless transmission, which allows the user to move freely within the loop.
Inductive hearing aids are used for a variety of applications, e.g. as aids for the hearing impaired in churches, theaters, cinemas, waiting rooms and lounges, as interpreter systems, at lectures in museums, exhibitions, etc.
In inductive hearing systems, an induction loop consisting of a wire wound is laid in the floor, in the wall or in the ceiling area and is controlled by a current amplifier. This creates a magnetic field within the loop which induces a voltage into the telephone coil of the hearing aid or into the inductive receiver. This voltage is converted again to an audio signal in the receiver.
